E-Axle Explained: Core Structural Components and Their Engineering Roles 1. Introduction: The E-Axle as the Core of Electric Truck Powertrains As truck electrification accelerates, the e-axle has transitioned from a passive structural member of the chassis into a key subsystem governing propulsion efficiency, durability, NVH, and packaging. With deep integration of the electric motor, reduction gearbox, and drive axle, the components traditionally concealed behind the wheels – such as the axle housing, half shafts, and wheel-end assemblies – now play critical engineering roles in determining the overall performance and reliability of the e-axle. The axle housing becomes the structural backbone that manages reaction torque, supports cooling and suspension interfaces; the half shaft becomes a dynamic torque-transmitting element with high transient response requirements; and the wheel end serves as the terminal load and torque interface, directly influencing energy recovery, safety, and thermal management. Brogen e-axle on the heavy-duty truck 2. Axle Housing in the E-Axle: Structural Foundation and System Integration Platform The axle housing is one of the most important structural components in an electric truck e-axle. It supports the vehicle’s static load – body, cargo, and passengers – while also enduring complex dynamic loads including vertical, lateral, braking, and traction forces. These loads fluctuate continuously based on road conditions and driving maneuvers, requiring the axle housing to provide high strength, stiffness, and durability to ensure safety operation of the entire e-axle. Axle housing for e-axles 2.1 Structural Types of E-Axle Housings 2.1.1 Integral (One-Piece) Axle Housing Produced by casting or welding, integral housings are the mainstream solution for heavy-duty truck e-axles.  Cast one-piece housings offer high strength and stiffness and are widely used in medium- and heavy-duty e-axles. They withstand heavy payloads, high impact loads, and demanding duty cycles. Welded one-piece housings provide lightweight construction and manufacturing efficiency, making them suitable for urban delivery vans and light commercial vehicles where mass reduction is critical. Brogen one-piece axle housing for heavy-duty truck e-axles 2.1.2 Sectional (Split) Axle Housing Split housings are assembled using bolts or other fasteners. They are easier to manufacture and service, but due to reduced stiffness and potential joint failure, they are less common in heavy-truck e-axle applications, especially where high loads are involved. E-axle with three-piece axle housing 2.2 Materials and Manufacturing Processes Common materials for e-axle housings include: Cast steel – Very high strength and toughness, suited for harsh environments, but more expensive to produce. Ductile iron – Offers excellent castability and balanced mechanical performance at lower cost, widely adopted for e-axles. Stamped and welded steel plate – Lightweight and material-efficient, frequently used in light-duty e-axles where mass matters. Manufacturing considerations: Casting allows complex geometries and high stiffness, but has a higher cost and longer production cycles. Welding enables cost-efficient, high-throughput production but requires strict process control to prevent weld defects that may impact reliability. 3. Half Shafts in the E-Axle: Precision Torque Transmission Components In an e-axle system, the half shaft transfers torque from the differential (or motor output via reduction gears) to the wheel ends. It must endure not only continuous torque loads but also bending forces and dynamic impacts from uneven road surfaces and steering operations. For commercial vehicles, these conditions are particularly demanding. Half shaft structure 3.1 Half Shaft Types in Truck E-Axles 3.1.1 Full-Floating Half Shaft The most widely used design in truck e-axles. The wheel hub is supported by two tapered roller bearings on the axle housing, so the half shaft’s sole function is torque transmission. It does not bear vertical or bending loads. This improves fatigue resistance, durability, and reliability – ideal for heavy-duty trucks and high-load electric applications. 3.1.2 Three-Quarter Floating Half Shaft Transmits torque and needs to withstand part of the bending moment. It’s less common in e-axles due to inferior load performance compared with full-floating designs. 3.1.3 Semi-Floating Half Shaft Simple and low-cost; it must carry both torque and wheel-induced loads. Used mainly in passenger cars and some light commercial EVs where cost and lightweighting take priority. Half shaft 3.2 Materials and Manufacturing Processes Common materials for e-axle half shafts include 40Cr, 42CrMo, and other high-strength alloy steels. Heat treatments such as quenching and tempering significantly enhance strength, toughness, and wear resistance. Typical manufacturing stages: Forging – Improves grain structure and ensures high mechanical strength. Precision machining – Ensures dimensional accuracy and fit with differential and wheel-end interfaces. Heat treatment – Enhances fatigue resistance and extends service life under harsh EV duty cycles. 4. Wheel-End Assemblies: The Terminal Interface of the E-Axle Drive System The wheel end is the part that directly connects an e-axle to the wheels and serves as the final stage of the drive system. Its performance has a direct impact on driving safety and handling. The wheel end is primarily composed of the hub, tire, braking components, bearings, and other parts. These components work together to enable vehicle driving, steering, and braking functions. Brogen e-axle wheel-end 4.1 Wheel Hub The hub supports the tire and connects to the half shaft via high-load bearings. Common materials: Aluminum alloy – Lightweight with strong heat dissipation, reducing unsprung mass and improving handling and efficiency. Often used in premium commercial vehicles. Steel – High strength and cost-effective, widely used in mainstream trucks and buses. Hub design must ensure strength, stiffness, and excellent dynamic balance; otherwise, vibration, steering shake, and reduced safety may result. 4.2 Tires Commercial vehicle tires must offer: High wear resistance Large load capacity Strong grip and puncture resistance Tire selection must match vehicle’s duty cycle and application: Long-haul EV trucks  → low rolling resistance, high mileage Construction vehicles → puncture-resistant, high-load tire structures Tire pressure maintenance is essential for both safety and lifespan. 4.3 Brake Systems at the Wheel End The braking system is a critical safeguard for vehicle safety, allowing the wheels to decelerate or stop quickly when needed. At the wheel end of commercial vehicles, the two commonly used braking types are drum brakes and disc brakes. Drum brakes – Simple, cost-effective, high brake torque. Limitations include poor heat dissipation

A Complete Overview of Automotive Steering Systems: Structure, Working Principles, and EPS/EHPS Technologies 1. Steering System Structure and Operating Principles 1.1 Steering System Structure Steering Control Mechanism: This includes the steering wheel, steering column, and the two tie rods connecting them. These components allow the driver to apply steering input to the vehicle. Steering Gear (Steering Mechanism): As the core of the steering system, the steering gear amplifies the driver’s input force and changes the direction of force transmission. Common types include rack-and-pinion, recirculating ball, and worm-crank designs. Steering Linkage: A series of rods and mechanical linkages between the steering gear and the steering knuckles. Their role is to transfer output force from the steering gear to the steering knuckle, enabling wheel angle changes while maintaining correct steering geometry. Power-Assist Systems: Systems such as electro-hydraulic power steering (EHPS) and electric power steering (EPS) use electronic control of hydraulic pumps or electric motors to provide steering assist, improving steering ease and driving comfort. 1.2 Operating Principle of the Steering System Using a rack-and-pinion system as an example: The steering wheel is connected to the steering column, so turning the wheel rotates the column. Through the steering intermediate shaft and joints, torque is transmitted to the input shaft of the steering gear. The rack-and-pinion mechanism converts the rotational input into linear (or near-linear) motion, pushing or pulling the steering linkage and steering knuckle, causing the front wheels to steer. The rack-and-pinion steering gear reduces speed and increases torque while converting rotational motion into linear motion. Rack-and-pinion type 2. Types of Steering Systems 2.1 Mechanical Steering Systems Mechanical steering linkages connect the steering gear to the wheels and transfer steering force to the knuckles while maintaining proper steering geometry. 2.2 Hydraulic Power Steering (HPS) Hydraulic power steering reduces steering effort and absorbs road shocks. The key feature of a hydraulic power steering system is that the power steering pump is driven either by the engine’s accessory belt or by an electric motor. The pump delivers pressurized steering fluid to the steering control valve, which regulates the pressure and directs the flow. The fluid is then routed to one side of the hydraulic cylinder inside the steering gear, where it generates the assist force that drives the rack-and-pinion mechanism. Rack-and-pinion type hydraulic power steering 2.3 Electro-Hydraulic Power Steering (EHPS) EHPS systems solve the drawbacks of traditional HPS. Instead of being driven by the engine belt, the hydraulic pump is driven by an electric motor. An electronic control unit (ECU) adjusts the motor speed and hydraulic flow based on vehicle speed and steering angle velocity. This enables continuously adjustable assist torque to suit both low-speed maneuvering and high-speed stability requirements. Electro-Hydraulic Power Steering 2.4 Electric Power Steering (EPS) Electric Power Steering (EPS) uses an electric motor to provide steering assist, applying torque to either the steering column or the steering rack. A gear reduction mechanism typically connects the motor to the steering components.  A torque sensor measures steering torque and direction. The ECU calculates required assist based on torque, steering direction, and vehicle speed. The motor outputs a corresponding torque to provide steering assistance. EPS assistance varies with steering torque, vehicle speed, and steering angle. With automated parking systems, the EPS motor can also control steering automatically. Characteristics: Low-speed steering: High assist for light steering effort High-speed steering: Lower assist for better road feel and vehicle stability Most EPS systems offer selectable steering modes (Comfort, Standard, Sport) with different assist curves. Electro-Hydraulic Power Steering EPS assistance varies with steering torque, vehicle speed, and steering angle. With automated parking systems, the EPS motor can also control steering automatically. Characteristics: Low-speed steering: High assist for light steering effort High-speed steering: Lower assist for better road feel and vehicle stability Most EPS systems offer selectable steering modes (Comfort, Standard, Sport) with different assist curves. EPS can be categorized by motor placement: 2.4.1 C-EPS (Column EPS) Brogen C-EPS The motor is mounted on the steering column. Advantages: Compact structure; suitable for small vehicles with low assist demand. Disadvantages: Motor vibration may directly affect steering feel; closer to the cabin → higher noise intrusion. 2.4.2 P-EPS (Pinon EPS) Brogen P-EPS The motor is mounted on the pinion of the steering gear. Advantages: Compact; suitable for small vehicles. Disadvantages: Similar to C-EPS, motor interference may affect steering feel. 2.4.3 DP-EPS (Pinon EPS) Brogen DP-EPS Adds an additional motor-driven pinion shaft. Advantages: Better noise performance; provides higher assist; motor acts on the rack → reduced sensitivity to torque ripple; suitable for mid-to-high-end vehicles Disadvantages: Higher cost 2.4.4 R-EPS (Pack EPS) Brogen R-EPS Uses a more precise ball-screw assist mechanism. Its operating principle is as follows: when the electric motor rotates, it drives the ball-nut through a belt pulley. As the ball-nut rotates, the recirculating balls inside convert this rotation into linear motion, moving the rack shaft left or right. Advantages: high efficiency; capable of large assist torque; commonly used in MPVs, commercial vehicles, and premium cars. 3.

How Electric Truck Axles Enhance Semi-Truck Performance: A Technical Look at the J6L BEV Developing battery-electric semi-trucks involves managing energy efficiency, thermal performance, system mass, and packaging constraints while keeping operating requirements in mind. At the 2025 China Commercial Vehicles Show (CCVS), FAW Jiefang presented a 400 kWh J6L 6×4 battery-electric semi-truck that uses dual electric truck axles. Its drivetrain configuration provides an example of how e-axle-based layouts can influence the performance and operation of a BEV semi-truck intended for demanding duty cycles. 1. Energy Consumption Characteristics The J6L is equipped with two 240 kW two-speed electric drive axles, replacing the more common centralized motor and prop-shaft system. 1.1 Mechanical Layout Effects Switching to electric truck axles removes the prop-shaft and several intermediate driveline components, reducing system mass by roughly 140 kg. A shorter transmission path also decreases mechanical losses, improving efficiency by about 5% during steady-state operation. 1.2 Operating Modes Each electric truck axle is equipped with a 2-speed transmission, allowing the vehicle to operate in five useful combinations: Both e-axles in low gear – for high-load launch, grades, or rapid acceleration. One low / one high – for low-speed, full-load stop-and-go conditions. Both in high gear – for loaded high-speed cruising (up to 89 km/h). One low / one neutral – single-axle drive at low speeds when empty to reduce energy use. One high / one neutral – single-axle drive at higher speeds when empty. This gear-state flexibility helps match torque and speed to varying load conditions, improving overall efficiency compared with a fixed-path contralized drivetrain. 1.3 Motor Cooling & Efficiency Both electric truck axles utilize oil-cooled flat-wire motors, which simultaneously support rotor and stator cooling. This reduces torque derating on long climbs and offers a modest efficiency improvement – around 2% – compared with water-cooled designs. 1.4 Estimated Energy Use Typical 49-ton BEV trucks transporting sand and gravel operate at: ~1.6 kWh/km loaded ~0.8 kWh/km empty With its dual-axle configuration and reduced mechanical losses, the J6L’s estimated energy use is: ~1.4 kWh/km loaded ~0.7 kWh/km empty   2. Packaging and Cost Considerations Current BEV heavy-truck layouts generally fall into three categories: Rear-mounted battery + centralized drive Under-frame transverse batteries + e-axle Side-mounted batteries + centralized drive The J6L uses rear-mounted batteries combined with dual electric truck axles, a layout that simplifies packaging on the existing J6L platform. Battery System Configuration Under-frame solutions frequently use three 171 kWh battery packs (513 kWh). While this increases range, it also raises cost. The J6L’s 400 kWh arrangement provides a balance for sand-and-gravel transport, where: A 342 kWh dual-pack layout is typically insufficient for the daily operating range A full 513 kWh system increases the cost significantly The chosen configuration reduces battery system cost while still meeting expected range requirements. Conclusion The J6L BEV reflects how electric drive axles can influence key aspects of BEV semi-truck development: reduced mechanical losses and lower mass, improved torque and speed matching under various load conditions, better energy consumption in mixed duty cycles, and straightforward integration on an existing platform. For OEMs evaluating next-generation BEV platforms, this example illustrates how e-axle configurations can support efficiency and packaging goals in heavy-duty commercial applications.

Maintenance & engine wear: Continuous idling shortens engine life and increases maintenance costs. These challenges make concrete mixer electrification an ideal solution to save fuel and reduce operational downtime. Our Electric Drive Solution for Mixer Drums We implemented a battery-powered electric motor system to enable concrete mixer electrification. Key benefits include: Independent drum rotation: Onboard battery powers the drum during loading, unloading, or idle periods, allowing the engine to be turned off without interrupting drum operation. Energy-efficient loop: Surplus engine energy is captured to recharge the battery, minimizing power draw. Reduced fuel consumption: Eliminates unnecessary engine idling while keeping the drum rotating. Improved operation & comfort: Air conditioning and other vehicle systems remain fully functional during drum operation. Results & ROI from Concrete Mixer Electrification After almost a year of operation: Trucks achieved monthly fuel savings up to $1,000. Engine wear and maintenance requirements were reduced. Rapid return on investment: initial system costs expected to be recovered within months.

Oil-Free Air Brake Compressor for Commercial EVs: The Next Step in Clean Mobility With the rapid growth of electric vehicles worldwide, the electrification of commercial vehicles has entered a stage of fast expansion. Among their key subsystems, the electric air brake compressor plays a critical role in the pneumatic braking system, air suspension, and other auxiliary air systems. It’s a core component that directly impacts vehicle safety, reliability, and efficiency – and is now entering a rapid phase of technological evolution. This article explores the current market landscape and development trends of EV air brake compressors, particularly for commercial vehicles. 1. What is An Electric Air Brake Compressor in Commercial Vehicles In traditional commercial vehicles, the air compressor is typically driven by the engine. However, in electric vehicles, which no longer rely on internal combustion, an electric air compressor replaces this function. It provides compressed air for the vehicle’s brake system, air suspension, and auxiliary actuators, making it an essential element of EV safety and performance. With strong government policies promoting EVs globally, the market demand for electric air brake compressors has grown significantly. Traditional air compressor Electric air brake compressor 2. Current Status of Electric Air Brake Compressor Technology The shift toward electrification in commercial vehicles has given rise to multiple types of electric air brake compressors, such as screw, vane, and scroll compressors. However, over nearly a decade of market validation, these designs have shown limitations such as oil-gas emulsification, low discharge pressure, and poor reliability – leading to their gradual replacement. Today, piston-type air compressors have become the mainstream solution for electric commercial vehicles, offering better efficiency, reliability, and adaptability to high-pressure systems. Screw compressor Vane compressor Scroll compressor Piston compressor Item Oil-lubricated piston type Screw type Vane type Scroll type Lubricating oil type Traditional diesel engine oil Special screw compressor oil Special vane compressor oil – Driving safety Safe If maintenance is not timely, it will contaminate the air system, causing rubber parts to expand and age, easily leading to brake system failure – Lubricant consumption Small Large Large – Lubricant emulsification and deterioration None Easy Easy – Environmental adaptability (air contact) Less contact with external air Easily affected by external air contamination – Oil-gas separator Not required Required Required – Oil separator filter element lifespan – Short Short – Lubricant temperature control Not required Required Required – Impact of ambient humidity Small Large Large – Discharge pressure Can withstand short-term overload General General Low Special maintenance experience requirements None High High Very high Environmental adaptability Good Poor Poor Poor Service life Good Poor Poor Poor 3. The Rise of Oil-Free Piston Electric Air Brake Compressor Most piston-type electric air compressors in use today are still oil-lubricated, which requires regular oil changes and maintenance. Problems such as oil leakage or contamination can lead to secondary pollution and increased maintenance costs. In constrast, oil-free air brake compressors eliminate the need for lubrication oil, reduce system complexity, and ensure clean, oil-free compressed air – protecting pneumatic components and improving environmental sustainability. Based on years of market application and customer feedback, the trend is clear: oil-free piston compressors are becoming the future direction of EV air brake compressor technology. Oil electric air brake compressor Oil-free electric air brake compressor 4. Oil-Free Air Brake Compressor Technology Overview Among current oil-free air compressor designs, scroll compressors have seen early adoption in electric vehicles. They offer compact structure, smooth operation, and high efficiency. However, due to their tight sealing gaps, scroll compressors require extremely clean intake air, making them vulnerable to dust and humidity, especially since compressors in commercial EVs are often mounted on the chassis. Additionally, scroll compressors tend to have high discharge temperatures and struggle to meet the >1 MPa high-pressure requirements of commercial brake systems. Maintenance is also costly, as damaged scroll plates must be replaced entirely. As a result, oil-free piston compressors have emerged as the mainstream solution due to their superior pressure performance, environmental adaptability, and long service life. Comparison of Oil-Free Air Compressor Types Item Oil-free piston air compressor Oil-free scroll air compressor Discharge pressure Strong high-pressure capability; easily meets the standard requirement of ≥ 1 Mpa. Limited by the scroll sealing structure, poor high-pressure sealing performance leads to low discharge pressure. High-pressure performance decays significantly over time, making it difficult to maintain 1 MPa for long periods. Structural sealing Use a direct-drive motor design with a simple and reliable transmission structure; minimal high-pressure attenuation. Requires a precise clearance between moving components to achieve sealing, resulting in high requirements for sealing materials. The complex sealing structure is prone to thermal deformation and leakage. Environmental adaptability Excellent adaptability; IP67 or higher protection level allows operation in harsh environments (high temperature, low temperature, high altitude). Both the orbiting and fixed scroll plates feature curved surfaces requiring high machining accuracy. The strict sealing demands on upper and lower end faces make it sensitive to environmental conditions. Cooling performance The compressor head uses air or water cooling with an additional cooler, providing excellent heat dissipation. The internal working chamber cannot be externally cooled, making heat removal difficult. Localized overheating occurs easily, resulting in high discharge temperatures. Maintenance Requires no special maintenance – only periodic air filter cleaning. High sealing precision requirements lead to faster seal wear. Maintenance involves disassembling the entire unit to replace seals, making servicing difficult and costly. If scroll plates are damaged, the entire assembly must be replaced. Service life High reliability and long service life. Due to its unique sealing structure, service life is highly dependent on working conditions. Components operate under high temperature, humidity, and pressure, significantly shortening lifespan and overall reliability. 5. Advantages of the Two-Stage Oil-Free Piston Air Brake Compressor In response to the GB 7258 national standard requiring brake air pressure above 1 MPa, and OEMs demanding even higher efficiency and emission reduction, two-stage oil-free piston compressors have become the latest evolution trend. They are designed for high discharge pressure, low exhaust temperature, high efficiency, and long service life. Single-stage oil-free

Mining Electrification Solutions: Electric Dump Truck System Design 1. Introduction The electric dump truck is a specialized off-highway vehicle designed for short-haul material transport in industries such as mining, metallurgy, cement, water conservancy, and construction. Its working conditions are characterized by steep slopes, short routes, large load variations, fixed transport lines, and complex operating environments. Traditional diesel-powered dump trucks face several challenges in these conditions: high fuel consumption, elevated maintenance costs, and shorter service life.  By contrast, electric dump trucks replace diesel engines and manual transmissions with battery packs and electric drive motors. When traveling on flat roads or downhill, the motor operates in regenerative braking mode, converting braking energy into electricity to recharge the battery. This not only reduces wear on the mechanical brake system – improving safety and extending component life – but also increases vehicle range. With fewer maintenance needs, high protection levels, and superior adaptability to harsh mining environments, electric dump trucks are becoming the preferred choice for heavy-duty operations. 2. High-Voltage System Architecture of Electric Dump Truck High-voltage system architecture for the electric dump truck (for reference) Electric dump trucks replace the conventional powertrain with a high-voltage system. The main high-voltage components include: traction battery, PDU, DC fast charging port, integrated controller, thermal management system, and other auxiliary high-voltage systems. ● Traction Battery It’s the energy supply unit in an electric dump truck, providing electric power to all vehicle systems. When the battery is depleted, it also requires recharging. Therefore, the energy flow of the battery is bidirectional. ● High-Voltage Power Distribution Unit (PDU) The PDU is a distribution hub for high-voltage power, supplying electricity to all components within the high-voltage system. For example, battery heating, charging circuits, and power distribution to the integrated controller. Inside the PDU are fuses, relays, and a pre-charge circuit for each controllable high-voltage loop.  Between the traction battery and the PDU, a Manual Service Disconnect (MSD) is installed. The MSD is a mandatory safety device that allows physical disconnection of the high-voltage circuit during battery servicing or vehicle maintenance. It ensures safe isolation of the high-voltage system and often incorporates fuse protection to enhance electrical safety and reliability. ● Thermal Management System The thermal management system integrates both heating and cooling functions, maintaining the traction battery within its optimal operating temperature range to ensure safety, efficiency, and extended service life. Brogen traction batteries for electric trucks Brogen PDU for electric trucks Brogen BTMS for electric trucks ● Motor Controller and Drive Motor The motor controller converts high-voltage DC from the integrated controller into three-phase AC to power the drive motor. It regulates motor torque and rotational direction, enabling smooth vehicle start, stop, forward, and reverse operations. Additionally, during braking or deceleration, the drive motor recovers kinetic energy, converts it into electrical energy, and feeds it back to the traction battery for extended range and efficiency. Brogen e-powertrain (motor+AMT) for heavy-duty trucks System schematic for Brogen’s electric motor + AMT e-powertrain ● DC Fast-Charging Port The DC fast-charging port delivers high-voltage direct current, which can be routed through the PDU directly to the power battery for rapid charging without additional processing. ● Integrated Controller The integrated controller receives commands from the VCU and coordinates both the main drive system and auxiliary subsystems. Key auxiliary loads include the cab air-conditioning compressor, PTC heater, electro-hydraulic power steering pump, air compressor, and DC/DC converter.  The DC/DC converter steps down high-voltage DC from the traction battery to low-voltage DC to charge the auxiliary lead-acid battery. Compared with traditional distributed controllers, the integrated controller offers reduced size and footprint, optimizing vehicle layout. Minimizing high-voltage external wiring between discrete controllers reduces potential failure points, lowers costs, and enhances overall system reliability and safety. Brogen 4-in-1 integrated auxiliary inverter System schematic for Brogen’s integrated auxiliary inverter ● Auxiliary High-Voltage Systems The electric A/C compressor and PTC heater serve as the core components of the HVAC system, delivering cooling and heating functions. The electric air compressor supplies high-pressure compressed air for the braking system. The electro-hydraulic power steering pump provides hydraulic assistance to the steering system. 3. Traction Battery Selection and Design At present, mainstream electric vehicles generally adopt ternary lithium batteries or lithium iron phosphate (LFP) batteries. LFP batteries use lithium iron phosphate as the cathode material and graphite as the anode material. Compared with ternary batteries, LFP batteries offer the following advantages: High safety performance: The decomposition temperature of LFP is about 600°C. Even under high temperature or overcharge conditions, it does not undergo structural collapse, generate excessive heat, or form highly oxidative substances as ternary batteries do. In the event of a collision or short circuit, LFP batteries are also highly resistant to explosion. Long cycle life: The cell cycle life can reach up to 4,000 cycles, and around 3,000 cycles at the PACK level. Excellent high-temperature performance: Wide operating temperature range with strong thermal stability. Environmental friendliness: LFP batteries contain no heavy metals or rare metals, making them non-toxic and pollution-free. These features make LFP batteries particularly well-suited for mining applications, where operating conditions are harsh, ambient temperatures vary widely, and safety requirements are stringent.

High-Voltage Power Distribution Unit (PDU) Design The High-Voltage Power Distribution Unit (PDU) is responsible for distributing electrical power throughout the vehicle’s high-voltage system. Its function is similar to a fuse box in a low-voltage electrical system, primarily managing power distribution and providing overload and short-circuit protection for high-voltage circuits. High-voltage distribution schematic Brogen PDU system, typically integrated with the battery system The PDU distributes the energy supplied by the power battery to the integrated controller, as well as to the battery heating and cooling systems. During DC fast charging, the charging current also flows through the PDU to charge the power battery. Additionally, the Battery Management System (BMS) is integrated into the PDU. The BMS performs the following key functions: Monitoring the total battery voltage and charge/discharge current. Monitoring battery status, including individual cell

Electrified Trailers: Driving the Next Evolution of Semi-Trailer Trucks 1. The Strategic Role of Semi Trailers in Commercial Vehicles In the commercial vehicle sector, semi-trucks and semi-trailers are typically manufactured by two separate companies. While semi-truck sales often attract more attention, semi-trailers represent an equally important and sizeable market segment. The performance of a tractor-trailer combination largely depends on how well the two units are coordinated and matched. Electrifying semi-trailers brings new opportunities. By integrating batteries into trailers, the overall driving range can be extended. In more advanced scenarios, an electrified trailer could even supply supplementary power to the semi-truck, reducing operating costs. This multi-mode adaptability – whether paired with internal combustion engine (ICE) semi-trucks, hybrid semi-trucks, or fully electric semi-trucks – creates flexibility in today’s mixed market where ICE trucks still dominate. For fleet operators, return on investment must be visible in the short term. This is why leasing models for intelligent or electrified trailers are emerging: the upfront cost of advanced perception and drive systems is high, but a leasing approach allows broader adoption. Traditional semi-trailers are already widely leased in the logistics sector, making this model a natural fit. 2. Technical Trends: Architecture of Electrified Trailers Despite trailers’ relatively simple structures, electrification presents unique engineering challenges. Semi-trailers require integration of electric drive components, with the most efficient solution being the use of an electric drive axle (e-axle) (Discover our e-axle solution for electrified trailers here). With the mature e-axle technology, trailers can become independent driving units, capable of moving under their own power while still requiring support from the semi-truck. This allows for better performance when combined with semi-trucks, as integrated control systems can optimize the overall semi-trailer truck dynamics beyond what conventional, loosely coupled combinations can achieve. Advantages of Semi-Trailer Truck Integrated Control With Electrified Trailers Energy Efficiency: Up to 20%-30% reduction in fuel consumption and CO₂ emissions through optimized power coordination; More than 50% of braking energy can be recovered; Supply power to refrigeration units or other auxiliary equipment. Performance: Improved traction on slippery surfaces (up to +80%); Enhanced acceleration (time reduced by 50%); Stronger climbing ability; Safer lane-change and overtaking capability. Cost Benefits: Lower lifecycle operating costs; Better synergy with smart vehicle technologies; Moderate weight increase offset by efficiency gains. Safety: Improved stability; Reduced risk of jackknifing or trailer swing; Integration with braking systems enables advanced dual electric braking control.

Engineering Challenges in Electrified Trailers Adapting semi-truck e-drive technology to trailers is technically feasible. The primary challenges lie in: Integrated Control: Developing precise tractor-trailer coordination strategies. Electronic Architecture: Reconfiguring trailer E/E systems to support additional electric drive and control functions. Lightweight Design: Since gross vehicle weight limits are fixed, adding e-axles and batteries reduces payload. This necessitates advanced materials and optimized structural design to preserve carrying capacity. 4. Industry Outlook and the Future of Electrified Trailer The commercial vehicle industry faces a paradox of limited market size but high R&D demands, as system complexity in trucks far exceeds that of passenger cars. This tension requires innovative approaches to balance performance, cost, and adoption. Under the dual trends of electrification and intelligent vehicle systems, technologies such as smart chassis, electrified trailers, and tractor-trailer integrated control are becoming core areas of research and competition. Electrified trailers, with their potential to boost efficiency, safety, and versatility, are set to become a vital part of the commercial transport market. 5.
