The main function of the BMS is to keep all the individual cells in the battery pack in their safe operating area (SOA) by monitoring the following physical quantities: battery pack charge and discharge current, individual cell voltage, and battery pack temperature. Based on these values, not only can the battery be operated safely, but also the SOC and state of health (SOH) calculations can be performed. Analog Devices has developed a series of battery monitors that can measure up to 18 batteries connected in series. The AD7284 can measure 8 batteries, the LTC6811 can measure 12 batteries, and the LTC6813 can measure 18 batteries.
