BATTERY SYSTEM CHARGING AND DISCHARGING METHOD AND APPARATUS, BATTERY SYSTEM, AND ELECTRIC VEHICLE

WIPO Patent Application WO/2023/122960

A1

Provided by the present application are a battery system charging and discharging method and apparatus, battery system, and electric vehicle; the battery system comprises a low-voltage battery and a high-voltage battery, and the high-voltage battery and the low-voltage battery are both used for being connected to a load. The battery system charging and discharging method comprises: obtaining a first power when a load is operating; obtaining a first SOC value of the low-voltage battery and a second SOC value of the high-voltage battery; controlling the charging and discharging process of the high-voltage battery and the low-voltage battery according to the first power, the first SOC value, and the second SOC value. In the described manner, the risk of over-discharge of the high-voltage battery and the low-voltage battery is reduced and the service life of the high-voltage battery and the low-voltage battery is prolonged.
