The battery management system (BMS) is the most important component of the battery energy storage system and the link between the battery pack and the external equipment that determines the battery's utilization rate. Its performance is very important for the cost, safety and reliability of the energy storage system .
The BMS collects data on the voltage of every cell and adjusts the balancing circuits as needed to maintain a balanced voltage. By ensuring cell balancing, the BMS can enhance efficiency, extend battery life, and minimize the risk of safety hazards. Passive Cell Balancing:- It is a method used to equalize the voltage of the individual cells.
A centralized BMS is a common type used in larger battery systems such as electric vehicles or grid energy storage. It consists of a single control unit that monitors and controls all the batteries within the system. This allows for efficient management and optimization of battery performance, ensuring equal charging and discharging among cells. 2.
