The embodiment of the invention provides a battery system protection method, control equipment and a computer storage medium. The battery system protection method comprises the following steps: acquiring an initial power state of a battery system according to the temperature of the battery system and the charge state of the battery system; a target discharge coefficient is determined according to the working condition of the battery system, the target discharge coefficient is 1 under the working condition that the battery system does not break down, and the target discharge coefficient is smaller than 1 under the working condition that the battery system breaks down. And obtaining a target power state of the battery system according to the target discharge coefficient and the initial power state, wherein the target power state is a product of the target discharge coefficient and the initial power state. According to the battery system protection method provided by the embodiment of the invention, the discharge capacity limiting coefficient under various faults in the actual operation of the vehicle is comprehensively considered, the initial battery system power state obtained theoretically is corrected through the discharge capacity limiting coefficient, and the over-discharge phenomenon of the battery system under various faults is prevented.

    本申请实施例提供一种电池系统保护方法、控制设备以及计算机存储介质。电池系统保护方法包括:根据电池系统的温度和电池系统的荷电状态获取电池系统的初始功率状态。根据电池系统的工况确定目标放电系数,目标放电系数在电池系统未发生故障的工况下为1,目标放电系数在电池系统发生故障的工况下小于1。根据目标放电系数以及初始功率状态得到电池系统的目标功率状态,目标功率状态为目标放电系数以及初始功率状态的乘积。本申请实施例提供的电池系统保护方法,综合考虑了车辆实际运行中各种故障下的放电能力限制系数,通过放电能力限制系数修正了理论下得出的初始电池系统功率状态,防止电池系统在各种故障下产生过放现象。
