BMS Main 2.1

The BMS Main 2.1 is a controller of the modular battery management system that has the following features:

measuring current flowing through the battery;
communication with BMS Logic that measure voltage and temperature of the battery cells;
management of charging and discharging the battery;
management of balancing the battery cells;
protection of the battery from damage caused by current, voltage, temperature, etc.;
communication with external equipment (chargers, inverters, indication panels) to provide needed battery operation mode;
communication with external systems over Ethernet, CAN, RS-485, Wi-Fi;
collecting and storing battery history data on an SD card.

The BMS Main 2.1 is used solely in civil areas. It does not use encryption and cryptography.

The BMS Main 2.1 is a part of Movicom Electric BMS, a modular battery management system, and controls the following devices:
