| 3 | The BMS Main 2.1b is a controller of the modular battery management system that has the following features: | ||
| 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. | ||
| 13 | |||
| 14 | The BMS Main 2.1b is used solely in civil areas. It does not use encryption and cryptography. | ||
| 15 | |||
| 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//. | ||
