The invention discloses a battery protection method, device and equipment and a storage medium, and the method comprises the steps: responding to a condition that the charging voltage of a vehicle battery is greater than any preset pre-overvoltage trigger threshold value in a vehicle driving process, and entering a corresponding battery pre-overvoltage protection mode, so as to reduce the charging voltage; in response to the condition that the charging voltage is reduced to be below a preset pre-overvoltage exit threshold, exiting the corresponding battery pre-overvoltage protection mode; the number of the pre-overvoltage trigger threshold values is multiple, each pre-overvoltage trigger threshold value is correspondingly provided with a battery pre-overvoltage protection mode and a pre-overvoltage exit threshold value, each pre-overvoltage trigger threshold value is larger than the corresponding pre-overvoltage exit threshold value, and the multiple pre-overvoltage trigger threshold values are smaller than or equal to a battery full charge cutoff voltage; the battery pre-overvoltage protection modes corresponding to different pre-overvoltage trigger thresholds are different. By setting the pre-overvoltage protection, the battery is prevented from triggering the overvoltage protection, the battery can be effectively prevented from being overcharged, and the battery safety and the vehicle use safety of a user are guaranteed.

    本发明公开了一种电池保护方法、装置、设备及存储介质,方法包括:在车辆行驶过程中,响应于车辆电池的充电电压大于预设的任一预过压触发阈值,进入相应的电池预过压保护模式,以降低所述充电电压;响应于所述充电电压降低至预设的预过压退出阈值以下,退出相应的所述电池预过压保护模式;预过压触发阈值包括多个,每个预过压触发阈值均对应设置有一个电池预过压保护模式和预过压退出阈值,每个预过压触发阈值均大于对应的预过压退出阈值,多个预过压触发阈值小于等于电池满充截至电压,不同的预过压触发阈值对应的电池预过压保护模式不同。通过设置预过压保护,以防止电池触发过压保护,可以有效防止电池过充,保障电池安全性和用户用车安全性。
