Electric Power Recirculating Ball Steering (eRCB) for Commercial Vehicles

Leave a Comment / Industry Insight, Technologies / July 1, 2024

Electric Power Recirculating Ball Steering (eRCB) for Commercial Vehicles As the commercial vehicle industry trends towards electrification, intelligent systems, and connectivity, the power steering systems in commercial vehicles are also moving towards electrification. The evolution of commercial vehicle steering technology has progressed through several stages: from mechanical steering, to hydraulic steering, to electro-hydraulic steering, and now to fully electric steering, such as the electric power recirculating ball steering. Our eRCB installed on hybrid electric trucks What is the Electric Power Recirculating Ball Steering (eRCB) System? Unlike traditional mechanical recirculating ball steering systems, the electric power recirculating ball (eRCB) steering system integrates an electric motor and a reduction mechanism at the input end of the mechanical recirculating ball steering gear. This system uses steering signals, vehicle speed signals, and active control commands to control the motor, generating steering torque. This allows for different levels of power assistance and enables active steering functions. How Does the Electric Power Recirculating Ball Steering Work? When the steering wheel is turned, a torque sensor sends a torque signal to the controller. This signal is generated by a torsion bar inside the steering shaft, where the ends of the bar twist relative to each other under external force, reflecting the angle of twist to the torque sensor. The steering torque is directly proportional to the torsion bar’s twist angle. A vehicle speed sensor sends a speed signal (a square wave signal) to the controller. The controller then processes the torque signal and the speed signal from the dashboard and uses a pre-set force model to control the DC motor. By adjusting the current to the motor, the output torque changes, which is amplified by the reduction mechanism to directly assist the steering gear. What Are the Advantages of Electric Power Recirculating Ball Steering Systems? Compared to traditional hydraulic power steering, electric power recirculating ball steering offers the following advantages: 1. Reduced Procurement Costs Traditional hydraulic power steering systems for electric vehicles require an additional electric motor and controller, as there’s no engine-driven hydraulic pump. This setup can cost significantly more than electric steering. 2. Fewer Components and Lighter Weight Hydraulic steering for electric vehicles requires extra components like hoses, reservoirs, pumps, motors, and controllers. In contrast, electric power steering is an integrated system that saves time and effort during assembly. It’s approximately 50% lighter than hydraulic steering, making it easier to install and maintain, while also enhancing vehicle layout and safety. 3. Extended Driving Range by 25% Hydraulic steering systems need a motor with at least 2 kW power that runs continuously. In contrast, electric steering only requires a 12V (or 24V) power source, with a bus only needing around a 400W motor. The system only consumes power when steering, leading to minimal energy loss. Tests show that this can extend the driving range by over 25%. 4. Improved Steering Ease and Stability The eRCB system adjusts the steering assistance based on vehicle speed—light and easy steering at low speeds and stable, secure handling at high speeds, improving vehicle stability and control. 5. No Hydraulic Fluid, No Leaks Since the eRCB system doesn’t use hydraulic fluid, it eliminates the risk of leaks and reduces environmental pollution. 6. High Reliability and Maintenance-Free The eRCB system is highly reliable, maintenance-free, and performs well even in low temperatures. 7. Broad Applicability The eRCB system is versatile, suitable for fuel-powered vehicles, and hybrid vehicles, and is the ideal choice for pure electric vehicles.

How Blade Battery Packs Benefit the Electric Truck?

Leave a Comment / Heavy Transport, Industry Insight, Light Commercial Vehicles, Technologies / May 20, 2024

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 / Heavy Transport, Technologies / April 12, 2024

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.
