The invention discloses a battery pack arranged in a vehicle, the vehicle including the battery pack and a control method of the battery pack. The battery pack includes: a battery module having battery cells; a relay unit configured to connect the at least one battery module to an engine unit of the vehicle; and a control unit connected to the relay unit and the engine unit to control the relay unit and the engine unit, in which the control unit operates the relay unit such that the engine unit idles when a temperature of a battery unit of the battery module rises above a predetermined temperature. By idling of the engine unit, the energy level of the battery cells of the battery module may be reduced. According to the present invention, thermal runaway does not occur when the state of charge (SOC) of the battery module is below a specific SOC, and only a small amount of heat is released even if thermal runaway occurs, thereby significantly reducing the risk of explosion or serial fire of the battery module.

    公开了一种设置于车辆的电池组、包括电池组的车辆和电池组的控制方法。该电池组包括:具有电池单元的电池模块;继电器单元,其配置为将至少一个电池模块连接至车辆的发动机单元;和控制单元,其连接至继电器单元和发动机单元,以控制继电器单元和发动机单元,其中当电池模块的电池单元的温度上升至预定温度以上时,控制单元操作继电器单元,使得发动机单元空转。通过发动机单元的空转,可降低电池模块的电池单元的能量水平。在电池模块的荷电状态(SOC)在特定SOC以下的情况下,不会发生热失控,即使发生热失控,也仅释放少量热量,由此显著降低了电池模块的爆炸或连环着火的风险。
