The ZEVA BMS12 modules offers a robust, automotive-grade solution for managing the lithium battery pack in your electric vehicle or stationary battery system, reporting cell voltages and temperatures over CAN bus to a master control unit.

Each module can manage up to 12 cells. An onboard module ID selector allows up to 16 modules to operate on the same CAN bus, for packs containing up to 192 cells.

Voltage thresholds can be programmed over CAN bus to suit almost any battery chemistry such as Lithium Iron Phosphate (LiFePO4), Lithium Cobalt (LiCo), Lithium Manganese (LiMn), Lithium Titanate (Li2TiO3) etc, and will work with any cell capacity. Onboard shunt balancers maintain pack balance by bleeding a small amount of power from any high cells throughout a charge cycle.

For a complete battery management system, BMS12 modules must communicate over CAN bus with a master controller such as our Electric Vehicle Management System (EVMS3), which is able to take action (either stop the charger or shut down the drive system) if a BMS12 reports a cell voltage out of safe operating range.
