【 摘 要 】

With the popularization of electric vehicles, the maintenance of power batteries has gradually become a major research topic in the maintenance of electric vehicles. This paper proposes a battery aging detection method based on the real-time vehicle condition of electric vehicles. Through the monitoring of current changes, the change of ohmic internal resistance of power battery is observed. And through the SOC changing trend when the electric vehicle is running, the battery health status is estimated, thereby effectively providing a reference for the user's electric vehicle maintenance. According to changes in the SOC, SOH, and ohmic resistance of the power battery, it is determined whether the power battery needs to be replaced.
