The invention provides a battery discharge protection method, device and equipment, and a medium. The method comprises steps of receiving a battery discharge request transmitted by a charging and discharging pile, and returning a battery discharge parameter to the charging and discharging pile; receiving a discharging mode entering instruction returned by the charging and discharging pile, issuinga discharging starting instruction to an automobile battery pack so as to trigger starting discharging, and controlling closing of countercurrent protection at the same time; receiving battery working environment data uploaded by a monitoring unit, and performing protection operation of an automobile battery pack; issuing a discharging stopping request to the charging and discharging pile, and controlling the automobile battery pack to quit discharging by the charging and discharging pile; receiving a discharging mode quitting instruction returned by the charging and discharging pile, and issuing a discharging stopping instruction to the automobile battery pack to trigger discharging stopping; receiving a discharging current uploaded by a monitoring unit, judging whether the discharging current is smaller than a set current value or not, and if so, controlling for starting countercurrent protection; otherwise, starting no countercurrent protection. The method is advantaged in that thewhole discharging process of the automobile battery pack can be protected in real time, and safety is ensured.
本发明提供一种电池放电保护方法、装置、设备和介质,方法包括接收充放电桩发送的电池放电请求,将电池放电参数返回给充放电桩;接收充放电桩返回的进入放电模式指令,下发开启放电命令给汽车电池组以触发启动放电,同时控制关闭逆流保护;接收监测单元上传的电池工作环境数据,对汽车电池组执行保护操作;下发停止放电请求给充放电桩,充放电桩控制汽车电池组退出放电;接收充放电桩返回的退出放电模式指令,下发停止放电命令给汽车电池组以触发停止放电;接收监测单元上传的放电电流,判断放电电流是否小于设定的电流值,如果是,控制开启逆流保护;否则不开启逆流保护。本发明能够对汽车电池组的整个放电过程进行实时的保护,确保安全。
