Battery Management System


ENNOID-BMS-SS-LITE is a charge only BMS oriented toward Light Electric Vehicles. 

Thanks to the Open-Source nature of ENNOID-BMS, customers can contribute to the project and adapt the BMS to their needs. Firmware & software repositories are available on our Github page.


NEW feature for 2022:


SS-LITE version has no pre-charging circuit & no main fuse. User must use an external anti-spark switch or anti-spark connector & use an external main fuse on the main discharge path. This version  of the BMS has no direct control over the battery discharge path.

*Status: 15S-LITE & 18S-LITE in production & shipping

**Boards are sold without accessories. Please buy the appropriate accessories for your own particular needs.

*(HD version with dual sided optional shunt & FETs). 

**Discharge/regen current is limited only when the BMS is wired to monitor the discharge/regen current path. There is no current limit if the BMS discharge/regen path is bypassed. See user guide for additional information.

Additional documentation:

**UART protocol

**CAN protocol

**The documentation pointed to could be outdated due to the constant evolution of the firmware data sets. The basis for UART & CAN implementation will stay valid despite firmware updates. You can refer to the official firmware source code for accurate data sets.
