3 -The BMS Main 2.1b is a controller of the modular battery management system that has the following features:
3 +BMS Main 2.1 is a modular BMS controller for 24-1200V batteries. It interacts with measuring modules, calculates the battery state, and protects the battery from damage.
4 4  
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.
5 +BMS based on the Main 2.1 can control up to 23 measuring modules and manage a battery consisting of 414 cells.
