Monitor

A BMS may 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 or voltage of periodic taps

  • Temperature: average temperature, coolant intake temperature, coolant output temperature, or temperatures of individual cells

  • State of charge (SOC) or depth of discharge (DOD), to indicate the charge level of the battery

  • State of health (SOH), a variously-defined measurement of the overall condition of the battery

  • Coolant flow: for air or fluid cooled batteries

  • Current: current in or out of the battery
