The invention discloses a charging method, a charging device, electronic equipment and a storage medium. The method comprises the following steps: determining a pre-charging current value according to the current state of charge and temperature of a power battery; charging the power battery based on the pre-charging current value; under the condition of determining that the charging state of the power battery meets a current reduction precondition, determining whether the maximum voltage value of a single body of the power battery meets a preset current reduction condition or not; and returning to execute the step of determining the pre-charging current value according to the current state of charge and temperature of the power battery and the subsequent steps until the maximum voltage value of the single body meets the current reduction condition under the condition that the charging state of the power battery does not meet the current reduction precondition or the maximum voltage value of the single body does not meet the current reduction condition, and returning to execute the step of determining the pre-charging current value according to the current state of charge and temperature of the power battery and the subsequent steps until the maximum voltage value of the single body meets the current reduction condition. And according to the target pre-charging current value, carrying out end current reduction charging on the power battery, wherein the target pre-charging current value is a pre-charging current value which enables the maximum voltage value of the single body to meet a current reduction condition. The method can prevent the power battery from being overcharged.

    本申请公开了一种充电方法、充电装置、电子设备及存储介质,该方法包括:根据动力电池当前的荷电状态和温度确定预充电流值;基于预充电流值对动力电池进行充电;在确定动力电池的充电状态满足降流前置条件的情况下,确定动力电池的单体最高电压值是否满足预设的降流条件;在确定动力电池的充电状态不满足降流前置条件的情况下,或者,单体最高电压值不满足降流条件的情况下,返回执行根据动力电池当前的荷电状态和温度确定预充电流值的步骤及其后续步骤,直至单体最高电压值满足降流条件后,根据目标预充电流值对动力电池进行末端降流充电,目标预充电流值为使单体最高电压值满足降流条件的预充电流值。该方法能够避免动力电池过充。
