BENEFITS

BENEFITS

  • Rapid Charging

    Up to 300A high output. Ideal for 12V / 24V / 48V lithium batteries.

  • 2-in-1, Motor Integrated with Controller

    Compact and lightweight design with no external regulator required.

  • Wide Compatibility

    Compatible with rated 14.4V / 27.2V / 51.2V LiFePO4 and other types of batteries.

  • Comprehensive Diagnosis & Protection

    Supports current monitoring & protection, thermal monitoring & derating, load dump protection, etc.

  • 85% Overall High Efficiency

    Consumes far less power from the engine and generates far less heat, resulting in substantial fuel savings over the whole life cycle.

  • Fully Software Controllable

    Supports continuously adjustable closed-loop voltage control and current-limiting control to ensure safe battery charging.

  • Superior Idle Output

    Extremely low turn-on speed with charging capability at 1,500 rpm (＞2kW), enabling efficient battery charging even at idle.

  • Dedicated Drivability Performance Improvement

    Software-defined slew rate for charging power ramp-up and ramp-down ensures smooth drivability. Software-defined adaptive idle power reduction helps prevent engine stall.

  • Customized Mechanical & Electrical Interfaces

    Simplified plug-and-play harness for easy installation and flexible compatibility with RVC, CAN 2.0B, J1939, and other protocols.
