Leave a Comment / EV Industry /

Understanding Electric Power Steering Solutions: Types and Key Differences The power steering system is a crucial component of a vehicle, serving as an important connection between the driver and the car. It has evolved alongside the overall development of vehicles and the emergence of new technologies. Initially, there was mechanical steering, followed by hydraulic power steering systems (HPS), electro-hydraulic power steering systems (EHPS), electric power steering systems (EPS), and now the latest steer-by-wire (SBW) technology. Depending on the location of the assist motor, electric power steering systems (EPS) are classified into C-EPS, P-EPS, DP-EPS, and R-EPS. Each type has its own unique functional and performance characteristics. Different Types of Electric Power Steering Systems 1. Column Assist Type Electric Power Steering (C-EPS) Motor placement: the motor and reduction gears are mounted on the steering column. The motor’s torque works together with the driver’s input to rotate the steering column, which then transmits force through the intermediate shaft and pinion to the rack, providing steering assistance. Applicable vehicle types: particularly suitable for compact vehicles that do not require excessive assistance. Structural characteristics: compact design, easy installation, and minimal required installation space. Driving experience: lightweight steering at low speeds, stable handling at high speeds, and excellent self-centering performance. Additional features: equipped with self-diagnosis and safety control functions, highly adaptable, allowing for customization of electric power steering columns and controllers based on different vehicle models. 2. Pinion Assist Type Electric Power Steering (P-EPS) Motor placement: the motor provides assistance directly to the pinion of the rack-and-pinion steering system, combining the precise adjustability of electric power steering with the strong road feedback typical of hydraulic power steering. System performance: equipped with a waterproof, compact, lightweight, high-performance integrated motor-ECU unit, the system delivers high rigidity and excellent dynamic steering performance. Structural characteristics: the compact, integrated housing structure enhances the precision of component manufacturing and improves overall product reliability. Cost: P-EPS is more expensive compared to C-EPS. 3. Dual-Pinion Assist Type Electric Power Steering (DP-EPS) Motor placement: an additional assist motor is placed on another part of the rack, applying steering force to the tie rod via a pinion. Together with the pinion on the intermediate shaft and tie rod, this forms a dual pinion structure. Applicable vehicle types: suitable for mid-size SUVs, large SUVs, MPVs, pickups, and other passenger vehicles, meeting the requirements for ADAS (Advanced Driver Assistance Systems). Performance advantages: the servo motor only operates when steering assistance is needed, reducing fuel consumption by 3-5%. It complies with ISO 26262 functional safety standards at the ASIL D level. The system is designed with high robustness to handle complex driving conditions, with high steering precision to support driving assistance at high speeds. Redundant design: the fully redundant DP-EPS system includes redundancy in power supply, communication, sensors, electronic control, and motor output, significantly enhancing the reliability and safety of the system. 4. Rack Assist Type Electric Power Steering (R-EPS) Motor placement: the motor typically applies force to the rack through a timing belt or ball screw. In some configurations, a coaxial motor directly provides assistance via a roller screw. Structural characteristics: the structure is relatively compact, making it suitable for scenarios where front axle loads are increasing and the steering system is positioned farther from the driver. Driving experience: it offers an enhanced steering feel and higher efficiency, making it more suitable for premium vehicles. Performance advantages: with a finely tuned steering feel and excellent NVH performance, it fully meets the steering needs of vehicles ranging from mid-size sedans to luxury MPVs. It also supports Level 2+ autonomous driving, including features like Lane Keep Assist (LKA), Automated Parking Assist (APA), and Remote Control Steering (RCS). Safety: the entire product platform is developed following ISO 26262 processes, ensuring functional safety at ASIL-D level. Key Differences of Electric Power Steering Systems After gaining a basic understanding of the different EPS structures, let’s take a look at the performance differences and suitable applications for each type: 1. Assist Effect and Applicable Vehicle Types EPS Type Maximum Assist Force Applicable Vehicle Types C-EPS 11 kN Compact cars, small SUVs P-EPS 12 kN Midsize cars, SUVs DP-EPS 13 kN Midsize/large SUVs, MPVs, pickups R-EPS 16 kN Luxury cars, large SUVs, performance vehicles C-EPS, with its compact structure, is typically used for vehicles that require moderate steering assistance. P-EPS, by applying assist force to the pinion, provides stronger assistance and is suitable for heavier vehicles. DP-EPS, with its dual-pinion design, offers even greater assist force to meet the needs of larger vehicles. R-EPS generally delivers the strongest assist, making it ideal for luxury and performance vehicles. 2. Energy Consumption and Efficiency by EPS Type EPS Type Energy Consumption Efficiency C-EPS Low Moderate P-EPS Moderate Relatively High DP-EPS Moderate to High High R-EPS High (operates only when needed) Very High While DP-EPS and R-EPS have relatively higher energy consumption, their servo motors only operate when steering assistance is required, effectively reducing fuel consumption in real-world use. Additionally, these systems generally exhibit higher efficiency, converting electrical energy into steering assistance more effectively. 3. Response Speed and Precision by EPS Type EPS Type Response Speed Precision C-EPS Moderate Moderate P-EPS Relatively Fast High DP-EPS Fast High R-EPS Very Fast Very High R-EPS typically exhibits the fastest response speed and highest precision, thanks to its advanced control algorithms and precise mechanical structure. DP-EPS also performs well, while C-EPS and P-EPS are comparatively slower and less precise. 4. Noise Levels and NVH Performance by EPS Type EPS Type Noise Level NVH Performance C-EPS Moderate Moderate P-EPS Lower High DP-EPS Very Low High R-EPS Very Low Very High Among these types, only C-EPS has the motor located in the passenger cabin, making it the noisiest and has the worst NVH experience. In contrast, P-EPS, DP-EPS, and R-EPS have their motors in the front compartment, resulting in better noise performance. Additionally, R-EPS benefits from its force transmission structure, offering the best NVH performance. 5. Redundancy Design and Safety by EPS Type EPS Type Redundancy Design Safety Level C-EPS Minimal

Electric Heavy-Duty Truck Design: Which E-Powertrain is Better?

Leave a Comment / EV Industry /

Electric Heavy-Duty Truck Design: Which E-Powertrain is Better? At Brogen, we’ve spent a lot of time developing electric axle systems for commercial vehicles, particularly in heavy-duty applications like semi-trucks, tractors, and trailers. In this article, we’ll explore different electric powertrain systems, compare solutions, and discuss the pros and cons of each. 1. Types of E-Powertrain Systems Electric powertrain systems for heavy-duty vehicles can be categorized into three main configurations based on motor layout: Central Direct Drive: Direct drive motor Electric Drive Axles: Parallel-Axis E-Axle Coaxial E-Axle Vertical-axis E-Axle Distributed Drive Systems  Wheel-End Drive Wheel-Hub Drive Each system offers unique advantages, and we’ll explore them in more detail below. But first, let’s look at some broader trends driving innovation in e-powertrain systems. 2. Key Trends in E-Powertrain Systems 2.1 Increasing Integration of E-Powertrain Systems More and more, motors, gearboxes, controllers, and other key components are being integrated into compact units. This not only reduces weight and space but also improves overall system efficiency and reliability. For example, our 360 kW drive assembly integrates the motor and gearbox into a single unit, which optimizes the layout for heavy-duty trucks and saves valuable space. Similarly, our 360 kW electric axle for heavy commercial vehicles combines the drive system, transmission, braking, and other key components into a compact, efficient assembly. Brogen 360 kW drive assembly for 40-ton to 90-ton HCV Brogen 360 kW E-axle for 4×2/6×2/6×4/8×4 HCV 2.2 Adoption of Dual-Motor E-Powertrain Systems Dual-motor setups are becoming increasingly popular, especially in high-end and specialized trucks. These systems offer better power distribution, improved energy efficiency, and enhanced performance for heavy loads. Our dual-motor drive assembly is a prime example, delivering continuous power during demanding conditions, such as hill climbs, while maximizing operational efficiency. Brogen Dual-Motor Drive Assembly for 55-180T HCV Brogen Dual-Motor 360 kW E-axle for 4×2/6×2/6×4/8×4 HCV 3. Central Direct Drive Systems: A Cost-Effective E-Powertrain Solution Central Direct Drive System Architecture Central Direct Drive System Examples Central direct drive systems are primarily used to convert traditional fuel-powered trucks into electric vehicles. In this configuration, the engine is replaced with an electric motor, along with an electric drive unit (EDU), battery packs, and other key components. The original chassis remains largely unchanged, making this solution adaptable for a wide range of commercial vehicles. Pros: Cost-Effective & Quick to Market: This is the most economical and fastest way to electrify existing vehicle platforms without extensive redesigns. Ease of Conversion: Many manufacturers opt for this approach as it allows them to enter the EV market without the significant financial and time investments required for developing a new platform. Cons: Limited Battery Space: Since the original chassis isn’t significantly altered, space for battery packs is restricted, which limits driving range and affects battery cooling system layout. Compromised Handling & Comfort: Converted models often have poor weight distribution, leading to increased braking distances and reduced driving comfort. Central direct drive systems are commonly used in short-distance transportation scenarios, such as ports, steel mills, power plants, and mines. They are less suited for medium- or long-distance travel. 4. Electric Drive Axles: Optimizing Space & Efficiency In contrast, electric drive axles (e-axles) eliminate the need for a drive shaft, reducing vehicle weight and improving system efficiency. E-axles also allow for better space optimization for battery packs, increasing driving range and better overall efficiency. Among the different types of electric drive axles, three main configurations stand out: parallel-axis, coaxial, and vertical-axis. Each configuration offers distinct advantages and challenges, making them suitable for various vehicle types and operational needs. 4.1 Parallel-Axis E-Axle Parallel-Axis E-Axle System Architecture Brogen Parallel-Axis E-Axle The parallel-axis electric drive axle is currently the most widely adopted configuration for electric axles in the market. In this system, the motor is positioned parallel to the axle, and the motor, drive axle, and AMT are integrated into a single unit. This design eliminates the need for a drive shaft, reducing overall system weight and improving transmission efficiency. Additionally, this configuration uses helical gears, which significantly enhance reverse braking capability—from the typical 30% to an impressive 100%. By removing traditional components such as the universal drive shaft, reducer, and suspension brackets, installation costs are significantly reduced compared to central direct drive systems. This compact design also saves weight and space, allowing for better battery placement and increased driving range. However, there are drawbacks. The large unsprung weight of the system, combined with its offset configuration, can negatively impact the vehicle’s handling, especially in heavy-duty applications. 4.2 Coaxial Electric Drive Axle Coaxial Electric Drive Axle Architecture Brogen Coaxial E-Axle The coaxial electric drive axle features a motor aligned directly with the axle housing. This configuration creates a more compact and concentrated power system, which optimizes the vehicle’s overall chassis layout. Due to its efficient space utilization, coaxial e-axles are ideal for smaller commercial vehicles like light vans and trucks weighing under 4.5 tons. However, their compact nature and lower power density make them unsuitable for heavy-duty vehicles, which require more robust power systems. 4.3 Vertical Axis Electric Drive Axle Vertical Axis Electric Drive Axle Architecture In the vertical axis electric drive axle, the motor is connected to the drive axle at a perpendicular angle. This setup offers some key advantages, such as lower installation costs and the efficient use of longitudinal space, which allows for better battery pack arrangement. Despite these benefits, there are significant trade-offs. The vertical axis design has lower transmission efficiency compared to parallel-axis e-axles, and its system power density is not as high. Additionally, the use of hypoid gears for speed reduction results in a smaller speed ratio and poorer performance in NVH (noise, vibration, and harshness). As a result, this configuration is more commonly used in medium- and heavy-duty commercial vehicles. 5. Distributed Drive Systems As electric vehicles continue to evolve, distributed drive systems are emerging as a powerful alternative to traditional powertrains. Distributed drive systems can be divided into two main types: wheel-end drive and wheel-hub drive. Each of these technologies offers distinct advantages, as well as unique challenges,

4 Motors With 1000 HP? Our Electric Truck Axle May Exceed Your Expectations

Leave a Comment / EV Industry /

4 Motors With 1000 HP for Electric Heavy Trucks? Our Electric Truck Axle May Exceed Your Expectations The semi-truck shown here is a battery-swapping electric tractor equipped with our 360 kW electric truck axles. It features two rear electric drive axles, each e-axle housing two motors, delivering 180 kW of peak power per motor. Together, they generate a total of 720 kW, nearly 1000 horsepower. And there’s even more beneath the surface. Our electric axle integrates the motors, along with key components such as the speed reducer and differential gear, directly into the rear axle. The total weight of the electric axle is 950 kg, with each axle capable of delivering up to 50,000 N.m of torque, ensuring abundant power for heavy-duty operations. One of the unique features of this e-axle is its distributed drive system. This means that each motor operates independently, providing added safety redundancy—if one motor fails, the other can continue to function normally. There are additional benefits as well. To improve efficiency, the vehicle’s design allows for both motors to work simultaneously or to alternate between them. When the truck is unloaded, only a minimal amount of power is used, as the motors take turns powering the vehicle. During start-up or climbing, both motors can work together, delivering maximum power. This cooperative strategy is coordinated with the vehicle’s overall control system. For fully electric trucks carrying heavy loads, alternating between the two motors helps prevent overheating, keeping both motors within their optimal operating range. This not only enhances reliability but also enables the motors to work together to deliver ideal power and torque when high demand is required. For example, the maximum torque output of our single electric axle reaches an impressive 50,000 N.m, an extraordinary figure for a heavy-duty tractor. We all know that traditional motor layouts are often limited by space and require numerous components. In contrast, the integrated design of our electric axle, with its compact central structure, reduces the number of parts needed. For example, our e-axle weighs 950 kg, contributing to a vehicle weight reduction of 300 kg. The highly integrated design also frees up valuable chassis space in electric trucks, a critical factor given the current focus on maximizing battery capacity for longer range. This central, compact electric axle allows for more or larger battery packs, improving range. It is also compatible with a variety of suspension systems, including air suspensions and multi-leaf springs, making it adaptable to different truck platforms. By integrating the entire axle assembly into the chassis, and using a highly compact dual-motor design, we’ve reduced the number of parts in the drivetrain, leading to higher transmission efficiency and more effective regenerative braking—both of which contribute to extending the vehicle’s range. This central, integrated electric axle not only offers higher reliability but also benefits from reduced weight, increased chassis space, and higher transmission efficiency. With the rise of hydrogen fuel cell systems, which require even more chassis space than pure electric trucks, this axle design is undoubtedly poised to become the mainstream choice, offering tremendous market potential in the future.

Optimizing Electric Pickup Truck Development: E-Axles Benefits

Leave a Comment / EV Industry /

Optimizing Electric Pickup Truck Development: E-Axle Benefits The Unique Requirements of Electric Pickup Trucks Pickup trucks, primarily commercial vehicles, have a chassis design more aligned with light commercial vehicles than with passenger cars or SUVs. Directly using passenger car electric powertrains in electric pickup trucks can increase costs and fail to meet the specific demands of pickup truck usage. A truck-style rear axle design is an economical and effective solution that meets the essential requirements of electric pickup trucks, such as traction, payload capacity, durability, and off-road capability. Additionally, it ensures superior towing performance. Electric Drive Axle Technology for Electric Pickup Trucks The axle is a critical element in the strength and durability of pickups and light trucks. The electric drive axle technology integrates the electric motor directly with the axle, allowing seamless integration with existing truck structures without the need for specialized suspension, chassis, or braking systems. This setup enables electric pickup trucks to retain the towing capacity of traditional fuel-powered vehicles while also accommodating higher payloads. The highly concentrated power system of the electric drive axle simplifies vehicle battery placement and features an integrated structure that adapts to the unique operating conditions of fully electric vehicles. Flexibility in E-Powertrain Configurations In addition to rear-wheel drive, pickup manufacturers can integrate a standard electric drive system into the front axle of their electric pickup trucks, achieving an electric four-wheel drive configuration. For the ultimate solution, a three-motor setup, including a front axle motor, offers the highest level of performance for electric pickup trucks. However, manufacturers can opt for a simpler rear-drive system or a lower power output axle, such as a 115 kW rear axle motor, which is generally suited for fully electric vehicles with a GVWR of 4.5 to 6 tons. The 150 kW electric drive axle is suitable for larger fully electric commercial vehicles. Benefits for OEMs This approach allows electric pickup trucks and light commercial vehicles to maintain their performance without compromising payload or towing capacity, all without requiring a complete redesign of the existing truck platform. These advantages make it easier for OEMs to transition to electrification. Additionally, the reduced number of moving parts in the powertrain translates to lower maintenance and servicing needs. High-Power Electric Drive Axles for Pickup Trucks Our high-power output electric drive axles feature the PMSM motor, offering peak power options ranging from 90 kW to 165 kW, with a top speed of up to 110 km/h.

Electric Pickup Truck Axle: Understanding the Difference Between Rigid and Flexible Axles Recently, BYD launched its first hybrid pickup truck: BYD SHARK in Mexico, showcasing its latest advancements in hybrid technology on a global stage. This vehicle, built on the DMO platform, features an off-road specific longitudinal EHS hybrid system in the front and a globally pioneering rear-drive electric powertrain at the rear. What sets this pickup apart is its “flexible axle” rear design, a significant departure from traditional pickups. As we enter the era of electric and hybrid pickups,  could traditional “rigid axles” become a thing of the past? What Are “Rigid Axles” and “Flexible Axles”? To understand this concept, it’s essential to know what an axle is. An axle, also known as a drive axle, connects the suspension to the vehicle’s frame or chassis, with wheels mounted at either end. It transmits power and supports the vehicle’s weight. Axles can be classified into two types based on their suspension structure: solid and independent. A solid axle, commonly known as a “rigid axle,” features a rigid beam that connects the wheels, ensuring they move in unison. On the other hand, a “flexible axle” uses an independent suspension system where the wheels can move independently, providing more flexibility and better ride comfort. The Shift to Flexible Axles in Electric Pickup Trucks In traditional pickup trucks, especially those with rear-wheel drive, the rear axle is typically a rigid axle because it needs to be rigid to handle the load. However, as pickups evolve into more passenger-friendly and electric-powered vehicles, many are transitioning to flexible axles. This allows the half-shafts between the differential and wheels to flex, offering better ride comfort and versatility. The BYD SHARK, mentioned earlier, is a prime example of this shift. Other electric pickup trucks, like the Radar RD6, Horizon, and various American models, also use flexible axles. The Tesla Cybertruck, Hummer EV, Ford F-150 Lightning, and Rivian R1T are all examples of electric trucks that have adopted this design. Even Toyota’s recently announced electric Hilux is expected to feature a flexible axle. Are Rigid Electric Pickup Truck Axles Becoming Obsolete? While many new electric pickup trucks are adopting flexible axles, some still use rigid axles, especially those designed for heavy-duty or off-road use. For instance, the Jiangling Daoda EV features a world-first high-performance oil-cooled coaxial electric drive axle, which is essentially a rigid axle integrated with an electric motor. This design offers superior load capacity, making it ideal for heavy-duty applications. Similarly, the Changan Hunter EV uses a hard axle structure for its electric drive axle. The single-motor rear-wheel-drive version delivers a maximum power of 110 kW and a torque of 300 Nm, retaining the characteristics of traditional solid axles while incorporating electric drive technology. Pros and Cons of Flexible and Rigid Electric Pickup Truck Axles Each type of axle has its advantages and disadvantages. Flexible axles, with their independent suspension, offer better ride comfort and are well-suited for light-duty, household, and light off-road use. However, they may compromise ground clearance, which can be a drawback on rough terrain. Additionally, the complex structure of flexible axles can limit customization options and increase the risk of damage when subjected to extreme conditions. Rigid axles, on the other hand, provide consistent ground clearance, making them more suitable for off-road and heavy-duty applications. They offer greater load capacity and are better suited for modifications. However, the added weight of a rigid axle, especially when integrated with an electric motor, can affect handling and reduce ride comfort. The Future of Electric Pickup Truck Axles While flexible axles are becoming more common, rigid electric drive axles remain essential for heavy-duty and off-road electric trucks. These axles provide consistent ground clearance, superior load capacity, and enhanced durability, making them ideal for demanding applications. Our rigid electric drive axles are designed to integrate seamlessly with electric powertrains, offering the strength and reliability needed for tough environments. As the market for electric trucks grows, hard axles will continue to be crucial for those who prioritize performance and durability. Learn more about our electric drive axle systems here.

DC-DC Converter: Unlocking the Energy Code of Electric Vehicles Introduction to the DC-DC Converter The onboard DC-DC converter is a crucial component in electric vehicles (EVs). It’s primarily responsible for converting the high-voltage DC power from the battery into the low-voltage DC power needed by various electronic components and control systems within the vehicle. The operation of a DC-DC converter involves multiple modules, including power conversion, driving, and control, ensuring that energy is safely and efficiently transferred. Functions of the DC-DC Converter In electric vehicles, the DC-DC converter plays several key roles. First, it provides the necessary power for systems like power steering, air conditioning, and other auxiliary equipment, ensuring the vehicle operates smoothly. Additionally, since many of the electronic components and control systems in a pure electric vehicle use low-voltage power, the DC-DC converter ensures that the low-voltage battery is sufficiently charged. In some systems, the DC-DC converter even replaces the traditional 12V alternator, becoming the primary power source for recharging the high-voltage battery and supplying the 12V power load. DC-DC Converter Types There are various types of onboard DC-DC converters, including boost, buck, and buck-boost converters, which can be selected and configured based on specific needs. When selecting a converter, factors such as the vehicle’s top speed, acceleration, weight, maximum torque, and power requirements must be considered to ensure the converter’s power capacity meets the vehicle’s needs. Future Trends It’s worth noting that as EV technology continues to evolve, onboard DC-DC converters are also being optimized and upgraded. In the future, with the rise of higher voltage systems and the adoption of 48V systems, DC-DC converters will play an even more critical role in providing stable and efficient power to vehicles.
