One way is to use a Battery Management System. In simple words, a Battery Management System, popularly known as BMS, is an embedded system that monitors battery voltage, state of charge (SOC), state of health (SOH), temperature and other critical parameters and also controls charging and discharging of a battery.
A battery management system monitors the voltage of individual cells. If the cell voltage is increasing, it will shut down the battery until the user adjusts the charging voltage. Over-discharge can happen if a battery is exposed to a high electric load.
A BMS may monitor the state of the battery as represented by various items, such as: • Voltage: total voltage, voltages of individual cells, or voltage of periodic taps• Temperature: average temperature, coolant intake temperature, coolant output temperature, or temperatures of individual cells
Being able to effectively monitor current is important to monitor battery pack safety and for most state-of-charge and state-of-health algorithms. Battery management systems must not only monitor temperature and voltage …
