The integration of a Battery Management System (BMS) into a lithium battery significantly enhances the performance and safety of the energy conversion device. A BMS is one of the primary components that gets a battery's voltage, current, and temperature. Moreover, it limits overcharging, over-discharging, and overheating. This allows the battery to perform optimally and increases its longevity. Also, the BMS balances the charge among battery cells which allows uniform performance across cells while preventing single cells from being stressed. The advantages provided by combining a lithium battery with a BMS make it effective for many applications, including home energy storage and electric vehicles, where utmost safety and reliability are essential
