Battery management is the management of the charge, temperature, and other parameters of a battery. This includes extending the battery life, increasing the amount of charge, and also balancing cell health. Battery management systems help to monitor and optimize battery performance and ensure the operating parameters of a battery remain within the manufacturer's recommended levels. The system also performs other tasks including charging, discharging, and safety features such as protecting against overcharge or over discharge. Battery management also requires regular maintenance, such as periodic testing and calibration of the battery system, to ensure optimal performance. Proper battery management helps to increase the longevity of the battery and minimize the risk of failure due to improper maintenance or abuse.
