Key Considerations for Medium & Heavy-Duty Truck Electric Powertrain
Medium- and heavy-duty trucks operate under significantly higher loads and longer duty cycles than light commercial vehicles. Truck electric powertrain selection therefore needs to consider not only peak performance, but also continuous power capability, gradeability, energy efficiency, chassis architecture, and application-specific operating conditions.
Energy Efficiency
Drivetrain efficiency has a direct impact on energy consumption and operating costs, particularly for high-mileage and continuous-duty applications.
Continuous-Duty Performance
Powertrain components must maintain stable performance during extended operation, repeated acceleration, and sustained high-load conditions.
Chassis Integration
Motor, transmission or axle, battery, thermal management, and auxiliary systems must be packaged within the available chassis space while meeting payload and service requirements.
Torque & Gradeability
High payloads and demanding gradients require sufficient wheel torque and continuous power to maintain vehicle performance under loaded conditions.
Reliability & Durability
Commercial powertrains must withstand repeated loading, vibration, temperature variation, and demanding operating environments over long service periods.
Operating Conditions
Payload, route profile, annual mileage, operating hours, temperature, and charging availability all influence the appropriate powertrain configuration.
Medium & Heavy-Duty Truck Electric Powertrain Architectures
We support multiple medium- and heavy-duty truck electric powertrain architectures. Central electric drive and integrated electric axle systems provide different approaches to drivetrain integration, while range extender systems can be combined with suitable electric drive architectures when extended operating range or greater energy flexibility is required.
01
Central Electric Drive Architecture
The central electric drive system integrates a high-power electric traction motor with a multi-speed AMT to provide efficient and controllable power delivery for medium- and heavy-duty commercial vehicles. The system connects to the vehicle’s existing propeller shaft and driven axle, providing a practical solution for applications requiring high torque, gradeability, and flexible drivetrain integration.
Engineering Advantages
Multi-Speed Torque Multiplication
Multi-speed AMT configurations provide additional torque multiplication and help maintain an efficient motor operating range across different vehicle speeds and load conditions.
Conventional Driveline Compatibility
The system connects to the vehicle's propeller shaft and driven axle, allowing integration with established commercial vehicle driveline architectures.
High-Load Capability
High-power PMSM motors and multi-speed transmissions provide the torque and continuous power required for loaded operation, gradeability, and demanding duty cycles.
Platform Adaptability
Different motor power levels, transmission ratios, and PTO configurations can be matched to vehicle weight, payload, axle configuration, and operating requirements.
Suitable Applications
- Heavy-duty dump trucks
- Construction and specialty vehicles
- Mining and industrial transportation
- Short-haul and site-based operations
- Heavy-load regional transportation
- PTO-equipped commercial vehicles
Recommended When
- High-load and high-gradeability performance is required
- Multi-speed torque multiplication is beneficial for the duty cycle
- The vehicle retains a conventional propeller shaft and driven axle layout
- PTO integration is required for auxiliary equipment
- The application involves demanding or off-road operating conditions
- Minimize changes to the existing chassis and driveline architecture

02
Integrated Electric Axle Architecture
Integrated electric axles combine the electric motor, reduction gear, and axle assembly into a single drivetrain unit. By eliminating the conventional propeller shaft and integrating the main drivetrain components, this architecture shortens the mechanical power path, reduces the number of mechanical interfaces, and provides a more compact layout for chassis and battery integration.
Engineering Advantages
Short Mechanical Power Path
Eliminates the conventional propeller shaft and reduces intermediate mechanical components between the motor and wheels.
Improved Battery Packaging Flexibility
The absence of a central propeller shaft creates additional space for low-mounted battery installation.
Reduced Mechanical Interfaces
Fewer separate drivetrain components and mechanical connections simplify vehicle-level drivetrain integration.
High Drivetrain Efficiency Potential
A shortened mechanical power path reduces transmission losses and supports efficient operation across commercial duty cycles.
Single- and Dual-Motor Options
Different drive configurations provide flexibility for vehicle power requirements and axle-level performance targets.
Suitable Applications
- Long-haul and regional electric tractors
- Medium- and heavy-duty cargo trucks
- Urban and regional logistics vehicles
- Port and terminal transport vehicles
- High-mileage fleet applications
- Dedicated battery-electric truck platforms
Recommended When
- Developing a dedicated battery-electric chassis
- High annual mileage is expected
- Battery capacity and chassis packaging are key constraints
- Operating routes are relatively predictable
- Drivetrain efficiency is a major vehicle-level consideration

Range-Extended Electric Truck Architecture
We provide EV range extender systems for medium- and heavy-duty commercial vehicles that combine electric propulsion with onboard power generation. By supplying electrical power directly to the vehicle’s high-voltage system, the range extender enables continued operation when battery charge is insufficient or charging is unavailable, while allowing OEMs to avoid oversized battery packs and maintain the advantages of electric drive.
With rated power options from 65 to 200 kW, our range extender portfolio supports trucks, buses, and specialized commercial vehicles across regional transportation, construction, sanitation, mining, and other demanding applications.
Engineering Advantages
Direct Engine–Generator Coupling
Reduces mechanical transmission losses through direct generator integration.
Flexible Energy Management
Supports constant-power, load-following, and efficiency-optimized generation strategies according to vehicle operating conditions.
Reduced Battery Dependency
Enables smaller battery configurations while maintaining the required operating range and vehicle performance.
Extended Operating Flexibility
Allows vehicles to continue operating beyond the practical range of battery-only operation without immediate access to charging infrastructure.
Regenerative Energy Recovery
Works with the electric drivetrain to recover braking energy and return it to the battery.
Suitable Applications
- Regional and intercity heavy-duty transportation
- Non-fixed-route commercial fleets
- Mining and resource transportation
- Construction and site-based operations
- Concrete mixer and dump trucks
- Commercial vehicles with limited charging access
Recommended When
- Pure-electric operation is preferred for daily driving
- Operating range exceeds practical battery-only capability
- Charging infrastructure is limited or unavailable along the route
- Daily utilization leaves limited time for charging
- Large battery packs would significantly increase vehicle weight or cost
- Flexible operation across different routes and duty cycles is required
