3 +The BMS Main 2.1b is a controller of the modular battery management system that has the following features:
3 3  
5 +* measuring current flowing through the battery;
6 +* communication with BMS Logic that measure voltage and temperature of the battery cells;
7 +* management of charging and discharging the battery;
8 +* management of balancing the battery cells;
9 +* protection of the battery from damage caused by current, voltage, temperature, etc.;
10 +* communication with external equipment (chargers, inverters, indication panels) to provide needed battery operation mode;
11 +* communication with external systems over Ethernet, CAN, RS-485, Wi-Fi;
12 +* collecting and storing battery history data on an SD card.

16 +The BMS Main 2.1b is a part of Movicom Electric BMS, a modular battery management system, and controls the following devices:
17 +
18 +* //BMS Logic 2.0//;
19 +* //BMS Logic 12//;
20 +* //BMS Logic 18//;
21 +* //BMS Logic RET//.
