Electric Power Recirculating Ball Steering (eRCB) for Commercial Vehicles

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.

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

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

blade battery for battery electric truck

How Blade Battery Packs Benefit the Electric Truck?

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.

3-in-1 on-board charger (OBC) + DCDC+ PDU onboard charger

Industry Insight

Everything You Need to Know About The On Board Charger for Electric Vehicles

Everything You Need to Know About The On Board Charger for Electric Vehicles What is an on-board charger? An On Board Charger (OBC) is a device that converts AC power into DC power. It transforms the AC voltage from charging stations into the DC voltage required by the battery. OBCs are installed in electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs). They enable these vehicles to be charged using AC power from residential or public charging stations. The output power of an OBC typically ranges from 3.3 kW to 22 kW. A significant advantage of OBCs is their ability to charge electric vehicles using standard household outlets. What are the different methods of charging an electric vehicle? Electric vehicle charging stations can be broadly categorized into two types: AC charging stations and DC charging stations. AC Charging Stations As the name suggests, AC charging stations provide alternating current (AC) from the electrical grid to electric vehicles. The onboard charger then converts the AC to direct current (DC) to charge the vehicle’s battery. These stations, also known as Level 1 and Level 2 chargers, are used in residential and commercial applications. The advantage of AC charging stations is that the OBC can adjust the voltage and current according to the vehicle’s needs. This eliminates the need for the charging station to communicate with the electric vehicle. However, the disadvantage is their low output power. It results in longer charging times. AC power from the grid is delivered directly to the OBC via an Electric Vehicle Supply Equipment (EVSE), which then converts it to DC and charges the battery via the Battery Management System (BMS). DC Charging Stations DC chargers take AC power from the grid and convert it to DC, bypassing the OBC to charge the battery pack directly. These chargers typically deliver high voltages up to 600V and currents up to 400A. Unlike AC chargers, which take 8-16 hours to charge a vehicle, DC charging stations can fully charge an electric vehicle in approximately 30 minutes. These stations are also known as Level 3 chargers, with the chargers referred to as DC Fast Chargers (DCFC) or Superchargers. The main advantage of DC chargers is their fast charging time. However, they are technically complex and need to communicate with the electric vehicle to charge it efficiently and safely. As shown in the typical DC charging system diagram, the EVSE bypasses the OBC and delivers DC power directly to the battery pack. The standard capacity of a DC charging station ranges from 50 kW to 300 kW. It’s more than 6 times the capacity of a single-phase on-board charger. However, AC charging through the OBC has less impact on the battery and minimizes battery aging. What are the functions of the onboard charger? The primary function of the OBC is to manage the charging process from the power grid to the vehicle’s battery. The OBC is designed to charge the battery as quickly as possible while minimizing battery degradation. It offers two charging methods: constant current charging and constant voltage charging. Constant current charging: this method charges the battery faster, but cannot fully charge the vehicle. Constant voltage charging: also known as trickle charging, this method charges the battery more slowly but with greater control, allowing the vehicle to reach a full charge. To optimize charging speed, the OBC uses constant current charging at the beginning of the charge cycle and switches to constant voltage charging toward the end. The OBC also plays a critical role in the bi-directional charging mode available in some vehicles. This capability allows it to convert DC power from the high-voltage battery pack back to AC power, supporting AC loads (Vehicle to Load, V2L), grid power (Vehicle to Grid, V2G), and even home power (Vehicle to Home, V2H). Hardware architecture of the OBC The OBC primarily consists of the following hardware components: Input Voltage Measurement Circuit: Measures the input voltage to control the conversion circuit. Input Filter: Suppresses internal noise or noise from external devices. Full-Wave Rectification Circuit: Converts AC voltage to DC voltage. Power Factor Correction (PFC) Circuit: Improves power efficiency degraded by waveform phase shifts. Voltage Conversion Circuit: Converts voltage using components such as an isolation transformer and field-effect transistor (FET) switches. Output Filter: Suppresses noise generated internally. Output Voltage Measurement Circuit: Measures the output voltage to control the conversion circuit. Control Circuit: Manages the conversion circuit and other components. DC/DC Converter: Provides power to the control circuit. Communication Interface: Facilitates communication with external devices. What are the trends and challenges in OBC development? The OBC is a critical component for both battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs). As the number of electric vehicles increases, the number of vehicles equipped with OBCs will also increase. At the same time, more electric vehicles will be equipped with DC fast charging capabilities.Key trends and challenges in OBC development include: Adaptation to 800V High-Voltage Platforms: OBCs will be compatible with these high-voltage systems. Increased Output Power: As 800V platforms become more common and battery capacities grow, OBCs will need to provide higher output power. Future OBCs will need to feature high voltage (high withstand voltage), high current, low loss, high heat resistance, and compact size. Bidirectional Charging Capability: OBCs will need to support bidirectional charging, allowing the conversion of DC power from high-voltage battery packs into AC power to support external AC loads. Use of Discrete High-Voltage Components: These components will be widely used in OBCs to enhance performance. Increased Power Requirements: The trend towards fast charging will significantly increase the power requirements of OBC topologies. Our On Board Charger Systems Engineered for top-tier power conversion efficiency and remarkable power density, our chargers cover a broad power spectrum, ranging from 3.3 kW to 40 kW. Whether you’re driving a passenger car, bus, van, or LCV, or require upfit power supply for specialized vehicles, our comprehensive solutions ensure seamless integration and optimal performance.

What Are The Benefits of Direct Drive System for Electric LCVs?

Two Major E-Powertrain Solutions for LCVs Electric power has become the primary driving force for new energy light trucks. These trucks typically employ two main power layouts: one utilizes a traditional drive motor paired with a gearbox and rear axle, while the other employs a combination of a motor and an electric drive axle. Initially, many automakers adopted the former approach to capitalize on emerging opportunities driven by policies and market demands. This involved directly modifying the architecture of conventional fuel-powered light trucks to create pure electric models, maintaining consistency with traditional fuel-based layouts. Developing an entirely new platform for new energy light trucks entails significant investments in manpower and finances, along with lengthy product validation processes. The “gas-to-electric” conversion model streamlines this process by simply replacing the original engine and transmission assembly with a motor and single-stage reducer. This not only reduces development time but also simplifies post-vehicle maintenance, resulting in lower costs. Moreover, the motor + reducer + rear axle combination closely resembles the power structure of diesel vehicles. The electric drive axle represents a novel technical solution that integrates components like the motor, reducer, and differential, enabling the axle to generate power output. Its major advantages lie in reducing vehicle weight and significantly increasing chassis space due to its high integration, thereby enhancing overall efficiency. Currently, traditional “gas-to-electric” new energy LCVs remain the preferred choice for EV builders due to their lower procurement and maintenance costs. Although they may be less technologically advanced than electric LCVs utilizing e-axle technology, their minor modifications to traditional power layouts ensure stronger reliability and stability by retaining the original vehicle structure. Brogen’s Direct Drive System for EV LCVs At Brogen, we offer both direct drive systems and electric axle systems.
