The LiBAL c-BPU100™ is a PCB based Battery protection unit, which combines 4 essential functions in one compact unit

Details

The LiBAL c-BPU100™ is a PCB based Battery protection unit, which combines 4 essential functions in one compact unit:


1. Monitor the current
2. Provide the correct power for the BMS through a DC/DC converter
3. Disconnect the battery when the BMS detect a safety critical error
4. A separate auto-off relay to enable the sleep mode function


By combining the 4 functions in one compact unit that integrate directly with LiBAL c-BMS24™, the total solution provide a powerful, compact and highly cost-efficient system.

The size of the c-BMS with LiBAL c-BMS24, compared with a traditional PDU solution, is 20 times smaller. This makes it an ideal choice for small compact vehicles.

For small vehicles with relatively small capacity battery packs, the “sleep mode” current consumption becomes critical. By integrating the DC/DC in the c-BPU the result is an extremely low consumption of 2,5 mW. This combined with the c-BMS build in auto-off function makes it an ideal system for the small robots, 2w vehicles and AGV’s. The auto-off function can be re-engaged by a physical push button, which can be ordered separately.
