The invention provides a battery charging and discharging protection method and system, a storage medium and equipment. The battery charging and discharging protection method comprises the steps of acquiring target discharging current and current actual discharging current; judging whether the current actual discharge current is greater than the target discharge current; if yes, acquiring the deviation value between the current actual discharging current and the target discharging current, and adjusting the request torque of the driving motor according to the deviation value so as to reduce the deviation value; acquiring actual discharging current after torque adjustment; judging whether the actual discharging current after torque adjustment is smaller than the target discharging current or not; and if yes, quitting the adjustment of the request torque. According to the battery charging and discharging protection method and system, the storage medium and the equipment, in the charging and discharging process of the power battery, the charging and discharging current is monitored in real time, the request torque of the driving motor is adjusted according to the deviation value, the deviation value is reduced, the battery current is limited within the normal working range, so that the battery is protected, the operating performance of the battery is improved, and the service life of the battery is prolonged.

    本发明提供一种电池充放电保护方法、系统、存储介质及设备,包括:获取目标放电电流与当前实际放电电流;判断当前实际放电电流是否大于目标放电电流;若是,获取当前实际放电电流与目标放电电流的偏差值,并根据偏差值对驱动电机的请求扭矩进行调节,以缩小偏差值;获取扭矩调节后的实际放电电流;判断扭矩调节后的实际放电电流是否小于目标放电电流;若是,则退出对请求扭矩的调节。上述电池充放电保护方法、系统、存储介质及设备,在动力电池充放电过程中,对充放电电流进行实时监控,同时根据偏差值对驱动电机的请求扭矩进行调节,缩小偏差值,将电池电流限制在正常工作的范围内,从而起到保护电池,提高电池工作性能,延长电池寿命。
