The invention discloses a battery liquid leakage diagnosis method and device, a storage medium and a vehicle, and the method comprises the steps: obtaining a plurality of first state parameters of a battery, the first state parameters comprise shell pressure, AC internal resistance and insulation resistance, and different first state parameters correspond to different preset risk levels respectively; the preset risk levels corresponding to the shell pressure, the AC internal resistance and the insulation resistance are from low to high; when the numerical value change of at least one first state parameter in the multiple first state parameters exceeds a corresponding preset threshold value, the first state parameter with the numerical value change exceeding the corresponding preset threshold value is determined as a first abnormal parameter; and determining a highest preset risk level corresponding to the first abnormal parameter as a first liquid leakage risk alarm level. According to the method and the device, an operator can more accurately judge the liquid leakage degree of the battery according to the preset risk level, so that the vehicle can be regulated and managed in time.

    本申请公开了一种电池漏液的诊断方法、装置、存储介质及车辆,该诊断方法包括:获取电池的多种第一状态参数,其中,所述第一状态参数包括壳压、交流内阻和绝缘电阻,不同的第一状态参数分别对应不同的预设风险等级,壳压、交流内阻和绝缘电阻对应的预设风险等级由低到高;当多种第一状态参数中的至少一种第一状态参数的数值变化超过对应的预设阈值时,确定数值变化超过对应的预设阈值的第一状态参数为第一异常参数;确定第一异常参数对应的最高预设风险等级为第一漏液风险报警等级。本申请能够使操作人员能够根据预设风险等级更加精确地判断电池的漏液程度,以便于及时对车辆进行调控和管理。
