The invention provides an automobile battery full-charge capacity updating method, device and equipment and a storage medium, and the method comprises the steps: obtaining a current battery temperature value, a current open-circuit voltage value and a current full-charge reference capacity value of an automobile, and determining a current battery health degree according to the current battery temperature value and the current open-circuit voltage value; according to the method, the target full-electric capacity value is calculated according to the current battery health degree and the current full-electric reference capacity value, and the actual full-electric capacity of the automobile is updated based on the target full-electric capacity value, so that when the actual full-electric capacity of the automobile is estimated, the influence of the battery temperature and the open-circuit voltage value on the battery health degree is fully considered; therefore, the accuracy of estimating the actual full capacitance of the automobile based on the battery health degree is high.

    本申请提供一种汽车电池满电容量更新方法、装置、设备及存储介质,通过获取汽车的当前电池温度值、当前开路电压值和当前的满电参考容量值,根据当前电池温度值和当前开路电压值确定当前电池健康度,根据当前电池健康度和当前的满电参考容量值计算目标满电容量值,并基于目标满电容量值对汽车的实际满电容量进行更新,由于在估算汽车的实际满电容量时,充分考虑了电池温度和开路电压值对电池健康度的影响,所以基于该电池健康度估算汽车的实际满电容量的准确度较高。
