The invention provides a battery system overcurrent protection method and a vehicle, and belongs to the field of vehicle battery safety protection. Due to the fact that a battery system of an existing vehicle cannot achieve overcurrent protection in the full-current stage, the overcurrent protection method for the battery system can detect the current in a high-voltage loop in real time when abnormal current occurs in the high-voltage loop connected with the battery system, and the current in the high-voltage loop is detected in real time when the whole vehicle is in the charging state. The real-time charging current is compared with a preset charging current standard, if the charging current meets a charging fault breaking condition, a breaking instruction is executed, and a charging high-voltage loop connecting the battery system and the charger is disconnected; when the whole vehicle is in a running state, the real-time discharge current of the battery system is compared with a preset discharge current standard, if the discharge current meets a running fault breaking condition, a breaking instruction is executed, a discharge high-voltage loop connecting the battery system and a load is disconnected, and the safety of the battery system is ensured.

    本发明提供了一种电池系统过电流保护方法及车辆,属于车辆电池安全防护领域。由于目前车辆的电池系统不能实现全电流阶段的过电流防护,本发明提供的电池系统过电流保护方法,能够在与电池系统连接的高压回路出现异常电流时,通过实时检测该高压回路中的电流,在整车处于充电状态时,比较实时充电电流和预设的充电电流标准,若该充电电流满足充电故障分断条件,则执行分断指令,断开连接电池系统和充电机的充电高压回路;在整车处于行车状态时,比较电池系统的实时放电电流和预设的放电电流标准,若该放电电流满足行车故障分断条件,则执行分断指令,断开连接电池系统与负载的放电高压回路,确保电池系统的安全。
