Leave a Comment / Public Transportation, Technologies /

AMT Powertrain System for Battery Electric Buses: Enhancing Efficiency and Performance The transition to battery electric buses has become a key focus for bus manufacturers and cities aiming to reduce emissions and improve public transport sustainability. In recent years, some bus manufacturers have shifted from traditional direct-drive systems to e-powertrain systems that include Automated Manual Transmission (AMT) for battery electric buses (BEB). But what does this mean for electric bus performance, and how does it affect the overall driving experience? What is an AMT Powertrain System for BEB? The direct drive system delivers power directly from the motor to the rear axle, offering a simple, reliable, and efficient design. In contrast, the AMT e-powertrain system utilizes a gearshifting mechanism to transmit motor torque to the rear axle, allowing for optimized performance and energy efficiency by adjusting the gear ratios.  AMT Powertrain System vs Direct Drive System: Performance In fact, not all BEBs should be equipped with an AMT system. Compared to the conventional direct-drive system, electric buses with AMT have both advantages and disadvantages. Let’s take a 12-meter battery electric bus as an example to focus on the power performance comparison between AMT powertrain and direct-drive systems. System Parameters AMT Powertrain Direct Drive System Total Weight 260 kg 364 kg Maximum Torque 3730 N.m 2800 N.m Length 716 mm 470 mm Width 614 mm 603 mm Height 592 mm 592 mm For a 12-meter BEB, the electric motor in the AMT powertrain system has a rated power of 80 kW, whereas the direct-drive system uses a more powerful 100 kW electric motor. However, the motor in the AMT system can reach a maximum speed of 3500 rpm, which is higher than the motor speed (3000 rpm) in the direct-drive system. Electric buses with AMT powertrain systems offer better hill-climbing ability (23%) and can achieve higher speeds (14%), though the acceleration time may be slightly longer due to the shifting process. Motor Parameters AMT Powertrain System Direct-Drive System Rated Power 80 kW 100 kW Peak Power 140 kW 200 kW Rated Torque 600 N.m 1250 N.m Peak Torque 1000 N.m 2800 N.m Maximum Speed 3500 rpm 3000 rpm Maximum Gradeability 23% 14% Maximum Vehicle Speed 116 km/h 107 km/h 0-50 km/h Time 16 s 13.4 s In terms of system efficiency during normal operation, the two types of systems are quite different. When comparing system efficiency at different speeds, we find that the direct-drive system performs more efficiently in the 40-60 km/h range, with lower overall energy consumption. However, in the speed ranges below 40 km/h and above 60 km/h, the AMT powertrain system outperforms, showing lower overall energy consumption. Overall, when considering a wider range of driving conditions, the AMT system tends to offer better energy efficiency. In typical urban driving conditions, the electric bus equipped with the AMT system has a simulated energy consumption of 68.3 kWh per 100 km, with actual test results showing 68.6 kWh per 100 km. In contrast, the electric bus using a direct-drive system has a simulated consumption of 72.5 kWh per 100 km, with test results showing 73.3 kWh per 100 km. AMT Powertrain System vs Direct Drive System: Cost Considerations Cost is another significant factor for bus manufacturers. While the AMT system offers enhanced perofrmance, the cost implications depend on the bus’s torque demands. For buses with lower torque requirements, the direct drive system may be more cost-effective. However, for high-torque applications, such as large electric buses, the AMT system proves more economical. By using smaller motors with the AMT system, bus manufacturers can reduce motor costs without sacrificing power, resulting in a more affordable overall vehicle. In essence, when the required torque exceeds 1500 N.m, the AMT powertrain system becomes the more cost-effective choice. Larger buses with higher power demands benefit the most from AMT technology, offering both cost savings and better performance. AMT Powertrain System vs Direct Drive System: Comfort & Reliability Beyond performance and cost, comfort and reliability are crucial factors for any bus manufacturer. AMT powertrain systems do introduce gear shifts, which can cause slight interruptions in power delivery and reduce comfort compared to direct drive systems, which offer smoother acceleration. However, technological improvements in AMT design can mitigate these discomforts. For example, the shifting process can be optimized to minimize interruptions, thus improving the passenger experience. From a reliability perspective, the complexity of the AMT system theoretically makes it less reliable than direct drive systems. However, through rigorous design and quality control, these concerns can be addressed. For instance, AMT products can be designed with durability in mind, achieving similar reliability levels as direct-drive systems. Additionally, the AMT system’s lightweight design, compared to traditional systems, contributes to overall vehicle weight reduction. Our AMT Powertrain Systems for Electric Commercial Vehicles At Brogen, we offer e-powertrain systems based on AMT technology, utilizing PMSM for drive. The AMT is co-axially connected to the motor, taking advantage of the gearbox’s speed control and torque-boosting features. This enables a smaller motor to achieve the same performance as a larger direct-drive motor, while also enhancing the vehicle’s adaptability and efficiency. Our e-powertrain system with AMT ranges from 60 kW to 550 kW, making it suitable for applications in buses, trucks, heavy commercial vehicles, municipal vehicles, and loaders.

Electronic Differential System (EDS) for Electric Vehicles – Introduction

Leave a Comment / Industry Insight, Technologies /

Electronic Differential System (EDS) for Electric Vehicles – Introduction What is the Electronic Differential System (EDS) for Electric Vehicles? The Electronic Differential System (EDS) is a system that uses electronic technology to replicate the functionality of a traditional mechanical differential. Far beyond just an extension of ABS, EDS stands out as a technological gem in modern automotive electronic control systems. The core function of EDS is to monitor and adjust the rotational speed differences between the vehicle’s drive wheels in real-time, effectively addressing wheel slippage in challenging road conditions. How Does the Electronic Differential System (EDS) Work? During acceleration—particularly on slippery, muddy, or uneven roads—one drive wheel may lose traction and start to slip. EDS intervenes instantly by using wheel speed sensors to capture real-time data and accurately identify slippage. Once slippage is detected, the system activates, applying precise braking force to the slipping wheel through a hydraulic control unit. By limiting the rotational speed of the slipping wheel, EDS transfers more power to the wheel with better traction. This dynamic adjustment not only maximizes the adhesion of the non-slipping wheel but also significantly enhances the vehicle’s traction and drivability. In simpler terms, EDS intelligently distributes power, ensuring stable performance in complex road conditions. It guarantees smoother driving while minimizing energy loss. Practical Applications and Benefits of EDS For everyday drivers, vehicles equipped with EDS deliver a more stable and seamless driving experience, particularly during critial scenarios such as starting, accelerating, or climbing. Whether navigating slippery urban streets or tackling rugged off-road trails, EDS enhances the vehicle’s adaptability and safety. Additionally, the system reduces the operational burden on drivers in challenging conditions, making driving more effortless and enjoyable. Our e-Powertrain Systems With EDS As a pivotal innovation in modern automotive technology, the EDS combines unique principles and practical results to offer unprecendented safety and convenience for drivers. Our distributed drive electric axles integrate this advanced technology to effectively prevent tire slippage and reduce tire wear, achieving a tire replacement cycle of 100,000 kilometers for buses. These systems are widely used in pure electric double-decker sightseeing buses, hydrogen fuel cell buses, battery electric buses, 18-meter articulated buses, airport shuttle buses, heavy-duty trucks, electrified trailers, and more.

One of the most significant benefits of electrication is zero emissions, leading to cleaner air around airports and contributing to global environmental goals. Additionally, electric GSE reduces noise pollution, which is particularly important in densely populated areas near airports. The safety of energy use is also greatly improved, with electric equipment offering enhanced security compared to traditional fuel-based counterparts. In terms of operational efficiency, electrification boosts both energy conversion efficiency and overall airport productivity. By transitioning to electric ground support equipment, airports can achieve not only better performance from individual equipment but also streamline the entire airport operation. The reduced workload for ground crews, coupled with the ease of integrating intelligent systems, accelerates the automotion of airport processes. Overall, electrifying airport ground support equipment ensures environmental benefits, enhances energy security, and improves the overall efficiency of airport operations while pushing forward the integration of smarter, more automated systems. How to Choose the Best GSE Batteries When selecting batteries for electric ground support equipment, it’s essential to understand the specific requirements for these devices. This selection process presents challenges, as airport operations prioritize safety, especially in civil aviation. The safety standards for airport GSE must exceed those required for road vehicles, given the critical nature of airport operations. The reliability of these batteries is also vital – minimizing failure rates is essential to maintaining high fleet availability. Furthermore, airport GSE batteries must be durable, with long lifespans that can withstand the diverse environmental conditions in which these vehicles operate, from extreme temperatures to high humidity levels. The batteries should also be cost-effective, easy to deploy, and capable of fast delivery. For these requirements, safety is paramount. The battery itself must ensure the safety of the equipment and, ultimately, the safety of airport personnel. With this in mnd, we design our battery systems based on four key dimensions of safety: mechanical, electrical, chemical, and functional. This comprehensive approach guarantees that every battery system provides full protection of both the equipment and operators. Our battery factory – production line In terms of improving reliability, we focus on enhancing the lifespan and durability of lithium-ion batteries, using advanced engineering methods to minimize the failure rates throughout the battery’s lifecycle. Innovations in materials, such as optimized cathodes and anodes, as well as the development of advanced manufacturing processes, significantly reduce the risk of mechanical and chemical degradation, thus extending battery life. Additionally, batteries used in airport GSE are designed with features like IP67, IP68, and IP69K ratings, which provide effective moisture and dust protection. High-performance thermal management ensures the battery can operate within a broad temperature range, making it ideal for various environmental conditions found at airports worldwide. Our battery factory – standardized battery modules and packs One major challenge for airport GSE electrification is the relatively small scale of the equipment compared to road vehicles, leading to a greater variety of types and applications. To control costs and reduce development time, we have adopted a standardized solution approach. This includes the use of standardized battery modules and packs to meet the diverse needs of airport ground support equipment. Such a solution ensures that the system is both cost-effective and market-proven,while also offering the flexibility for small-batch, multi-type production.

The Best Batteries for Airport Ground Support Equipment

Leave a Comment / Industry Insight, Specialty Equipment /

The Best Batteries for Airport Ground Support Equipment: Choosing High-Performance GSE Electrification Solutions As airports transition toward sustainability and electrification, choosing the right batteries for ground support equipment (GSE) is crucial. From tow tractors and shuttle buses to baggage conveyors and forklifts, electrification helps reduce carbon emissions, improve energy efficiency, and enhance operational performance.  This guides explores key considerations for selecting airport GSE batteries, comparing battery types, voltage systems, and charging methods to meet the needs of modern airports. Why Lithium Batteries Are the Best Choice for Airport GSE Electrification Lithium-ion vs. Lead Acid Batteries While lead-acid batteries have historically been used in airport vehicles like baggage tractors, the industry has largely shifted to lithium iron phosphate (LFP) batteries due to their superior performance. Here’s a comparison: Feature Lead-Acid Batteries Lithium (LFP) Batteries Energy Density 30-45 Wh/kg 120-160 Wh/kg Charging Time 5-6 hours (0.2C rate) 1-2 hours (0.5-1C rate) Cold Weather Use Poor, with significant loss Good with insulation options Cycle Life 400-1000 cycles 2000-4000 cycles Maintenance High (e.g., water refills) Minimal (virtually maintenance-free) Environmental Impact Lead and acid pollution Green and eco-friendly Battery Management Limited or none Advanced Battery Management Systems (BMS) Lithium-ion vs. NCM Batteries: Why Safety Matters Airports require the highest safety standards, making lithium iron phosphate (LFP) batteries are the optimal choice over nickel-cobalt-manganese (NCM) batteries. Why LFP Batteries Are Safer? Thermal Stability: LFP batteries withstand temperatures up to 700-800°C before decomposition, compared to 200°C for NCM batteries, reducing fire risks. Proven Reliability: Widely used in electric buses, LFP batteries account for 98% of China’s electric bus market, demonstrating their safety and performance under demanding conditions. While NCM  batteries are favored for passenger cars due to their compact size and lightweight design, the safety and durability of LFP batteries make them better suited for electric ground support equipment. Key Advantages of Lithium Batteries for Airport GSE High Energy  Density: Delivers more power in a compact and lightweight degisn, optimizing vehicle performance. Longer Lifespan: Reduced replacement frequency translates to lower lifecycle costs. Superior Cold Weather Performance: Ideal for year-round operations, even in outdoor environments. Advanced BMS: Ensures safety, efficiency, and real-time monitoring. High Voltage Systems: Optimizing Efficiency for GSE Batteries When it comes to battery voltage, the choice between low-voltage (80V) and high-voltage (300V-600V) systems is critical. Why High Voltage (300V-600V) is Superior? Higher Efficiency: High-voltage systems minimize energy loss and improve operational efficiency. Enhanced Safety: Lithium batteries, with advanced BMS, support higher voltages safely. Scalability: High-voltage configurations, such as the 576V, meet the power demands of larger GSE. In constrast, lead-acid batteries are limited to 80V systems due to technical constraints, making them less efficient and impractical for modern GSE electrification needs. Charging Solutions for Airport Electric GSE Efficient charging is vital for electrified airport GSE. Here are the best practices for airport battery charging infrastructure: The optimal solution is distributed charging, conveniently located near parking spaces. Use standardized charging equipment (including charging voltage, protocols, and interfaces). Ensures “vehicles are compatible with all stations, and stations are compatible with all vehicles.” Distributed, near-parking charging is the best approach for airport electric ground support equipment due to the diverse range and unique designs of these vehicles. Battery-swapping is challenging and impractical for most airport GSE, making it unsuitable for this approach. Most airport GSE have limited range and are not designed for long-distance charging or swapping, making centralized charging facilities less ideal. Establishing 2-3 battery maintenance stations within the operational zone while receiving periodic battery inspections and maintenance. This is an excellent solution for maintaining battery health in newly constructed airports.  Choosing the Right Motor and Controller for GSE Airport GSE should use permanent magnet brushless motors paired with multi-in-one motor controllers.  Advantages of This Setup: High Motor Efficiency: Permanent magnets enhance efficiency and reliability. Integrated Controllers: Combining multiple controllers (e.g., for drive, hydraulic, and air systems) into a single unit improves compactness, reduces wiring complexity, and enhances reliability. Rugged Design: Water-cooled, IP67-rated controllers withstand harsh operating environments while maintaining electromagnetic compatibility. Conclusion: Powering the Future of Airport Operations Electrifying airport GSE with high-performance electric batteries like LFP systems is essential for achieving sustanability goals. By choosing the right battery type, voltage system, and charging solutions, airports can reduce carbon emissions, lower operating costs, and enhance equipment reliability.  For more insights on the best battery solutions for your airport’s ground support equipment, contact us to explore customized battery systems tailored to your needs.

Battery Electric Bus vs Hybrid Electric Bus vs Hydrogen Fuel Cell Bus: Overview and Comparison

Leave a Comment / Industry Insight, Public Transportation /

Battery Electric Bus vs Hybrid Electric Bus vs Hydrogen Fuel Cell Bus: Comparison Today, in addition to traditional fuel-powered vehicles, buses powered entirely or primarily by alternative energy sources are gaining attention. There are three main types of new energy buses, classified by their power source: battery electric bus, plug-in hybrid electric bus, and hydrogen fuel cell bus. Plug-in Hybrid Electric Buses These buses combine a conventional fuel engine with electric components like motors, batteries, etc. They can charge their onboard energy storage devices from an external power source. Current operating models include two main types: gas-electric hybrids and diesel-electric hybrids. They can run in either electric-only mode or hybrid mode. In short-range trips, they operate in electric mode to save fuel and reduce emissions. For longer journeys, they switch to hybrid mode to extend range. Hydrogen Fuel Cell Buses Fuel cell buses generate electricity through a chemical reaction between hydrogen and oxygen, which powers the bus. Unlike conventional electric vehicles that draw power from grid-charged batteries, fuel cell buses use hydrogen as the main fuel source, supplied through hydrogen refueling stations similar to gas or charging stations. With high energy density, zero emissions, and quick refueling, they offer a promising alternative to traditional engines. Battery Electric Buses Battery electric buses rely entirely on electric power, using a motor, battery, and controller. They produce zero emissions, run quietly, and minimize vibration, making them a popular choice among new energy buses today. Battery electric buses are further categorized by their charging methods: fast-charging plug-in buses, standard-charging plug-in buses, and battery-swapping buses. Fast-Charging Battery Electric Bus: These buses have a charging rate of 3C or above. they utilize high-power batteries (such as lithium titanate, multi-composite lithium, or lithium manganese batteries) to achieve high charge and discharge rates, enabling fast charging. Standard Plug-in Battery Electric Bus: These buses have a charging rate below 3C. Battery-Swapping Electric Bus: These buses have removable batteries that can be quickly swapped with fully charged battery packs using automated or semi-automated equipment, providing a fast energy supply for the vehicle. Comparative Analysis of Different Electric Bus Types Bus Type Pros Cons Fast-charging plug-in battery electric bus Short charging time; optimizes space and infrastructure usage at bus depots; smaller batteries are required, making the bus lighter Higher battery cost; increased power demand strains the grid and requires expensive infrastructure; energy costs can be high due to peak-hour charging Standard-charging plug-in battery electric bus Lower battery costs reduce financial pressure on fleet operators; can charge overnight during off-peak hours, cutting costs; slower charging is gentler on batteries and the grid Requires more space at depots due to a lower station-to-bus ratio; additional staff may be needed for overnight charging; larger batteries are needed to meet daily demands, which adds weight Battery-swapping electric bus Fast battery swaps, usually 7-8 minutes for four battery packs, allow for efficient recharging; centrailized battery management extends battery lifespan High battery costs; large space is needed to store charged and used batteries; charging multiple batteries at once can strain the grid Plug-in hybrid electric bus Easy to refuel with fuel or gas; economical due to reduced fuel consumption during start and acceleration Higher maintenance due to breakdowns; limited fuel-saving benefits in practice Hydrogen fuel cell bus Zero emissions using renewable hydrogen fuel Technology is still developing; building hydrogen refueling stations is costly When comparing these options based on cost-efficiency, space needs, grid demand, operational flexibility, and durability, the standard-charging plug-in electric bus stands out for its balanced performance across most categories, though it does require more depot space.

Coaxial eAxle for Light Trucks: Technology Overview and Performance Analysis

Light Commercial Vehicles, Technologies /

Coaxial eAxle for Light Trucks: Technology Overview and Performance Analysis Traditional fuel-powered trucks reply on a complex drivetrain consisting of an engine, clutch, transmission, driveshaft, and axle. This setup is not only heavy but also has low transmission efficiency. Early electric trucks often adopted a “retrofit” approach, replacing the engine and transmission with a motor and reducer. However, this direct-drive solution was both costly and inefficient. With the growing understanding of electric truck design and the need to lower costs, reduce energy consumption, and lighten vehicle weight, the industry is shifting toward integrated electric drivetrains. Today, many small and light-duty electric trucks are equipped with a coaxial eAxle. A coaxial eAxle integrates the motor, planetary reducer, differential, and axle housing into a single, compact unit, significantly shortening the drivetrain, reducing parts, and simplifying structure. This system offers traction, braking, and efficient energy conversion while ensuring higher transmission efficiency than direct-drive systems. It also features automatic transmission and regenerative braking, which help extend driving range by recovering energy. Advantages of Brogen Coaxial Drive eAxle Over Central Motor Direct-Drive At Brogen, we provide coaxial drive eAxles, suitable for electric light duty trucks. They have the following advantages: Structural Efficiency:The coaxial drive eAxle combines the motor, planetary reducer, differential, and axle housing in one integrated unit, creating a short drivetrain with fewer parts and a simpler structure. In contrast, the direct-drive approach requires separate motor, reducer, driveshaft, and axle assemblies, resulting in a longer, more complex drivetrain. Space Efficiency: The coaxial design is highly integrated, freeing up valuable chassis space and simplifying the assembly process. Direct-drive systems, on the other hand, require space for multiple components, complicating the overall vehicle layout. Energy Efficiency: With a direct-drive and planetary reduction transmission, the coaxial eAxle achieves an overall transmission efficiency of ≥94%, while traditional direct-drive systems fall below 90% due to a longer drivetrain and additional components. Transmission Process: In the coaxial system, power from the battery drives the motor shaft, which in turn powers the differential and planetary reducer to move the wheels. Direct-drive systems use the motor torque to drive a longer sequence of parts, resulting in lower efficiency. Weight Advantage: Coaxial drive axles are 10-25% lighter than direct-drive systems, reducing energy consumption, increasing motor speed capacity, and offering a higher power density, which extends range. Direct-drive systems are bulkier and lower in power density. Technical Superiority: Coaxial eAxles support a high level of regenerative braking and align with future trends in drivetrain integration. Direct-drive systems, by contrast, offer lower levels of integration and energy recovery. Maintenance Benefits: Coaxial drive eAxles have fewer components, which simplifies maintenance and reduces lifecycle costs. Direct-drive systems, with more parts, tend to have more complex maintenance requirements. In sum, the coaxial electric drive axle offers a highly integrated, efficient, and cost-effective solution for electric light trucks, aligning well with the industry’s movement towards compact, high-performance e-powertrains that maximize both range and durability.
