Design of lithium battery management system in civil aircraft

Battery management system ( BMS ) is very important to ensure the safe and stable operation of lithium batteries. Among them, battery balancing technology is a key technology in BMS design. It can adjust the state of charge ( SOC ) of each battery cell in the battery pack and prevent the battery from overcharging or discharging, thereby prolonging the overall lif e of the battery pack and ensuring the safety of use. In this paper, a battery balancing technology suitable for civil aircraft is given in combination with the scenario of emergency power supply for civil aircraft, and this battery balancing method is verified by simulation. Finally, a design scheme of lithium battery management system (BMS) with high reliability and high safety is given.
