The invention discloses an automobile storage battery aging prediction method and system, a vehicle and a storage medium. The automobile storage battery aging prediction method comprises the following steps that the voltage, the current, the temperature and the state of charge SOC of a storage battery are obtained; calculating the internal resistance Ri of the storage battery; comparing the internal resistance Ri of the storage battery with a theoretical aging internal resistance threshold value R of the storage battery in the current state of charge SOC; and if the internal resistance Ri of the storage battery in the current state of charge SOC is greater than the theoretical aging internal resistance threshold value R, indicating that the service life of the storage battery expires, and sending out alarm information, otherwise, indicating that the service life of the storage battery is in a normal state. The aging problem of the storage battery can be accurately predicted.
本发明公开了一种汽车蓄电池老化预测方法、系统、车辆及存储介质,包括以下步骤:获取蓄电池的电压、电流、温度和荷电状态SOC;计算蓄电池的内阻Ri;将蓄电池的内阻Ri与蓄电池在当前荷电状态SOC下的理论老化内阻门槛值R进行对比;若蓄电池在当前荷电状态SOC下的内阻Ri大于理论老化内阻门槛值R,则表示蓄电池的寿命到期,发出报警信息,否则表示蓄电池的寿命处于正常状态。本发明能够准确预测蓄电池的老化问题。
