The invention relates to the technical field of batteries, in particular to a battery box and a battery box thermal runaway control method. The battery box comprises a battery unit, a cooling system,a bypass circuit, a detection unit and a control system; the cooling system is used for cooling the battery unit; the bypass circuit is connected between the battery unit and the cooling system; the bypass circuit is provided with a discharge switch; the detection unit is used for detecting thermal runaway early warning parameters of the battery unit; and the control system is connected to the detection unit and the discharge switch and is used for judging whether the battery unit has a thermal runaway risk or not according to the thermal runaway early warning parameters so as to control the discharge switch to discharge the battery unit when the battery unit has the thermal runaway risk and supply power to the cooling system by utilizing the discharged electric quantity. By means of the design, thermal runaway can be reduced, spreading of thermal runaway is restrained, discharged electric quantity can be supplied to a cooling system, the discharged electric quantity is effectively utilized, and more economical efficiency and environmental friendliness are achieved.

    本发明涉及电池技术领域,尤其涉及一种电池箱及电池箱热失控控制方法;电池箱包含电池单元、冷却系统、旁支电路、检测单元以及控制系统;冷却系统用以冷却电池单元;旁支电路连接于电池单元与冷却系统之间,旁支电路设置有泄放开关;检测单元用以检测电池单元的热失控预警参数;控制系统连接于检测单元和泄放开关,用以根据热失控预警参数判断电池单元是否存在热失控风险,以在电池单元存在热失控风险时控制泄放开关,而使电池单元放电,并利用泄放的电量为冷却系统供电。通过上述设计,本发明能够减少热失控的发生、遏制热失控的蔓延,并能够将泄放的电量供给冷却系统,有效利用泄放的电量,更具经济性和环保性。
