Our Battery Management System is a dedicated technology, monitoring the pack's voltage and temperature to ensure safe and efficient operations.

Easy Integration

Dual CANbus communication protocol allows OEMs to communicate with the battery's J1939 (automotive standard) CANbus and use the second CANbus to communicate with the existing communication network without having to reprogram the legacy system.

Easy Troubleshooting

Via standard CANbus diagnostic protocols.
