The module supports CAN bus communication, enabling seamless integration with the vehicle control unit (VCU), motor controller, and onboard charger. For example, in an electric logistics truck, it communicates directly with the controller to optimize power flow during acceleration or regenerative braking, enhancing overall energy efficiency.

Comprehensive Protection and Compliance with Industry Standards

Safety is paramount in high-voltage systems. The module incorporates multi-level protection, including overvoltage, undervoltage, overcurrent, short-circuit, and thermal safeguards to ensure system stability under all operating conditions.

It complies with key automotive and marine safety standards, including ISO 16750, E-Mark, and CE certifications, assuring global compatibility and reliable operation in mission-critical commercial vehicles.

Flexible Voltage Configuration for System Optimization

Each electric platform has unique voltage requirements. The High-Power DC-DC Power Module offers flexible configuration options, supporting both step-down and step-up modes.

For instance, it can step down from 800 V to 48 V for auxiliary circuits in an electric bus or boost from 400 V to higher levels for propulsion systems in hybrid marine applications. This adaptability allows OEMs and integrators to optimize their system architecture efficiently and cost-effectively.

Seamless Integration with Onboard Charging and Power Management Systems

In addition to motor drives and controllers, our DC DC module is designed to integrate with onboard charging systems and energy management units. By coordinating energy distribution during driving and charging cycles, it ensures that the entire powertrain from charger to converter to controller and operates in balance.

For electric fleets with fast-charging requirements, this coordination enables quick turnaround times and improved system longevity through optimized thermal and power management.
