A Battery Management System is any electronic system that manages a rechargeable battery, such as by protecting the battery from operating outside its safe operating area, monitoring its state, calculating secondary data, reporting that data, controlling its environment, authenticating it and / or balancing it.
A BMS monitor the state of the battery as represented by various items, such as:
Voltage: total voltage, voltages of individual cells, minimum and maximum cell voltage
Temperature: average temperature
State of charge or discharge, to indicate the charge level of the battery
Current: current in or out of the battery
A BMS protects its battery by preventing it from operating outside its safe operating area.
The BMS controls the charging and discharging, immediately takes action when certain (critical) values are exceeded and safeguards an efficient energy transfer.
The BMS is designed for use with Lithium Iron Phosphate batteries. Its function is to manage the battery bank and prevent overcharging or over discharging.
