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,

EV Truck Drive Systems: Direct Drive Motor vs. E-Axle

Leave a Comment / EV Industry /

When it comes to the pure EV truck, understanding the differences between traditional electric motor structures and modern e-axle systems is crucial. Let’s use an electric dump truck as an example to explore these differences. Traditional Drivetrain Structure – Direct Drive Motor The traditional drivetrain in electric trucks closely resembles the layout found in conventional vehicles. The drive motor, equivalent to a diesel engine, is the heart of this system. Directly behind the motor is a reducer, functioning similarly to a traditional gearbox. The reducer’s job is to increase torque by reducing the motor’s speed, effectively amplifying power. This amplified power is then transmitted through a driveshaft to the rear axle. The rear axle, with a gear ratio of approximately 5.857, is comparable to that of traditional dump trucks. How It Works A notable feature of this system is the two-speed function of the reducer, which allows the vehicle to switch between different gear ratios based on the load, similar to shifting gears in a traditional transmission. This functionality provides both speed and power as needed. E-Axle System Now, let’s delve into the e-axle system. An e-axle integrates the electric motor with the rear axle, combining four major functions: the motor, rear axle, transmission, and differential. This integration brings several significant advantages: However, the e-axle system does present challenges. Integrating the motor with the rear axle reduces space for torque amplification mechanisms, potentially limiting the power output compared to traditional setups with a gearbox. Achieving high power levels with an e-axle requires advanced design and engineering capabilities. Brogen’s Solutions At Brogen, we supply traditional drive motor and e-axle systems for electric vehicle builders. Our e-axle for heavy-duty trucks can deliver a maximum output torque of 50,000 Nm, providing ample power for these vehicles. Our electric motors offer power options ranging from 165 kW to nearly 800 kW, catering to various commercial vehicles, including light trucks, tractors, concrete mixers, and more. Explore our cutting-edge electric axle solutions and see how Brogen can help you achieve success in the rapidly expanding e-mobility sector. Contact

How Blade Battery Packs Benefit the Electric Truck?

Leave a Comment / EV Industry /

Electric Trucks Equipped With Blade Batteries: Higher Energy, Lower Consumption The latest all-electric truck from BYD features blade battery packs. Introduced by BYD four years ago, these LFP blade battery packs eliminate the module design, reducing many structural components. The close connection between the upper and lower casings and the battery cells significantly increases volumetric energy density, reaching levels comparable to high-energy-density ternary lithium batteries. This battery electric vehicle model boasts a battery capacity of 94.3 kWh, providing a pure electric range of over 275 kilometers, surpassing the typical 100~200 kilometer range of industry-standard electric light trucks. In addition to the impressive energy density, blade battery technology offers higher thermal stability, lower thermal runaway temperature, smaller thermal runaway reactions, and a reduced likelihood of thermal runaway compared to ternary lithium and standard LFP batteries. This makes the light-duty truck, which operates over longer distances annually, safer. The blade battery’s exceptional thermal management extends battery life, improves charging and discharging efficiency, and shortens charging time. This all-electric truck can achieve over 100 kilometers of range with just half an hour of charging, further enhancing operational efficiency. Electric Truck Chassis Optimization: Better Layout, Higher Load Capacity Unlike traditional electric light trucks that position the standard battery boxes on the sides of the chassis or hang them in the middle, this electric truck’s blade battery is semi-embedded within the chassis frame. This structure integrates the battery into the chassis, making it part of the vehicle’s framework, providing both an energy source and structural rigidity. This design completely revolutionizes traditional electric light truck chassis layouts. Additionally, the semi-embedded design increases the chassis’ ground clearance, improving overall vehicle possibility. The flat-laying design of the chassis battery allows the truck to use a direct-drive system with an integrated electric drive axle. This system features a flat-wire motor and reducer within a shared casing, improving slot fill rate and efficiency. The lightweight aluminum alloy casing enhances transmission efficiency and reduces energy loss compared to traditional direct-drive systems. In terms of the suspension design, the vehicle uses a 3/5+6 leaf spring, with significantly more leaves in the rear axle springs, directly boosting the vehicle’s load capacity. Cabin Design: More Space, Lower Wind Resistance Building on the previous generation electric light truck, which positioned the integrated controller and battery systems on the sides of the chassis under the body, this EV truck continues this design, thanks to the more compact blade battery pack. This allows for a more spacious cabin layout. The cabin details have been optimized, upgrading the traditional mechanical handbrake to an electronic handbrake for increased comfort during driver rest periods while charging. Additionally, the vehicle’s battery system is split into two sets: one located on the side of the chassis under the body, and the other under the tilting cab, powering the low-voltage system of the cabin. This separated design enhances the stability and safety of the cabin’s power supply system. Summary In summary, the new electric light-duty truck, equipped with a 94.3 kWh blade battery, not only significantly improves vehicle range but also addresses user-identified issues through comprehensive upgrades to the chassis structure and cabin design. By leveraging blade battery technology, the vehicle reduces costs and increases efficiency for users. With competitive blade battery prices and enhanced electric truck battery capacity, BYD’s approach to batteries for electric vehicles sets a new standard in the industry.

Introduction of the Electric Drive Axle for Heavy Duty Trucks

Leave a Comment / EV Industry /

Introduction of the Electric Drive Axle for Heavy Duty Trucks Sales of electric trucks have continued to rise in 2023 compared to 2022, driven by strong and ambitious government policies. For heavy-duty vehicle manufacturers, adopting a reliable and powerful electric powertrain system is crucial to staying competitive in this rapidly expanding market. As demand for sustainable transportation grows, integrating advanced electric systems will be key to their long-term success. The Evolution of the Electric Drive Axle for Heavy Duty Trucks The evolution of heavy-duty trucks has gone through three distinct phases, with a vision of the future of electric mobility shaping the landscape. First, traditional fuel-powered trucks dominated the roads, with cabs that were flat and high drag coefficient. These trucks relied on engine-based power systems located at the bottom of the cab. The next phase saw the emergence of gas-electric heavy-duty trucks, which retained the central drive model but swapped the engine for electric motors. However, these vehicles retained conventional propulsion systems that were bulky, inefficient, and compromised cargo space due to rear-mounted battery boxes. Today, all-electric heavy-duty trucks typically use the electric axle as the e-powertrain system. EV solutions with electric drive axles provide increased transmission efficiency and space flexibility. At the same time, cabin structures are redesigned to lower the center of gravity and improve aerodynamics. Why The Electric Drive Axle is a Better Choice for Battery-Electric Trucks Building on the advanced design of the electric axle drive system, the structural design of the chassis for pure electric heavy-duty trucks can be further optimized, resulting in more efficient use of space. For example, all-electric heavy-duty trucks using our e-axle solution can eliminate traditional driveshafts, allowing the chassis structure to be redesigned to accommodate the battery spread flat across the chassis. This layout has many advantages: Placing the battery flat at the bottom allows for a larger battery capacity, extending the range while minimizing intrusion into the cargo area. By using a box-shaped beam frame structure, the battery pack is placed within the box frame structure, ensuring both battery safety and full utilization of the chassis load capacity. Lowering the vehicle’s overall center of gravity reduces the risk of rollover during cornering and improves driving stability and maneuverability. The overall appearance of the vehicle is improved. Analysis of Different Electric Powertrain Systems for Heavy Trucks At present, the primary e-powertrain configurations for electric heavy trucks encompass several distinct forms: Different configurations of electric powertrains for heavy-duty trucks Analysis of configuration characteristics of different electric drive axles Comparison of dual-motor central drive and dual-motor distribute drive systems An Example of Our Electric Drive Axle for Heavy Duty Trucks Let’s take our 360 kW eAxle as an example, which is suitable for 6×4 and 4×2 tractors and heavy-duty trucks. Compared to similar eAxle products on the market, our eAxle integrates two motors, providing higher system power and torque with a smaller footprint, and has 100% regenerative braking capability, eliminating mechanical differentials. This results in lower space requirements, weight, and cost. Our electric drive axle installed on the heavy-duty truck Additional Safety Redundancy In addition, our distributed drive system minimizes layout losses, reduces weight, and incorporates fault and safety strategies. The two drive systems are completely independent, consisting of a motor + 2-speed AMT and wheel-side reducer, using electronic differential technology and independently controlling the left and right drive systems. In the event of a single motor failure, the other motor can continue to operate normally, ensuring system safety. 23% System Weight Reduction Weight of different electric powertrain solutions for heavy trucks In contrast to the central drive system, our distributed drive system has achieved a weight reduction of 23.6%. Similarly, compared to the motor gearbox integration system, our distributed drive system has managed to reduce weight by 23.9%. Good Passability The distributed drive system boasts a 7.3% increase in ground clearance compared to the central drive system. Moreover, it achieves an even greater elevation of 11.7% when compared to the motor gearbox integration system. Higher Transmission Efficiency Compared to the central drive system, our distributed drive system demonstrates a 6% enhancement in overall transmission efficiency. High Security Currently, heavy-duty trucks are only equipped with ABS and lack ASR, ESC, and EDL. With our EV motor’s electronic differential system strategy control, heavy trucks can be equipped with ASR/ESC safety configurations, improving vehicle traction, stability, and safety.
