The invention discloses a battery pack thermal runaway treatment system and a vehicle, and belongs to the technical field of vehicles. The battery pack thermal runaway treatment system comprises a battery pack, a spraying assembly located in the battery pack, a control assembly and a controller. The control assembly communicates with the spraying assembly, a first cooling liquid pipeline of the first cooling system and a second cooling liquid pipeline of the second cooling system, and the controller is electrically connected with the control assembly and used for controlling the control assembly to block a channel between the spraying assembly and the first cooling liquid pipeline and a channel between the spraying assembly and the second cooling liquid pipeline based on state parameters of the battery pack. Or the cooling liquid in the first cooling liquid pipeline and/or the second cooling liquid pipeline is guided into the spraying assembly. When the thermal runaway phenomenon of the battery pack occurs, the control assembly can extract the cooling liquid in the original first cooling system and/or second cooling system of the vehicle to spray and cool the battery pack, and an independent cooling liquid storage tank is not needed, so that the occupation of the battery pack thermal runaway treatment system on the internal space of the vehicle is reduced.
本公开是一种电池包热失控处理系统及车辆,属于车辆技术领域。电池包热失控处理系统包括电池包、位于电池包内的喷淋组件、控制组件和控制器。控制组件分别与喷淋组件、第一冷却系统的第一冷却液管路、第二冷却系统的第二冷却液管路相连通,控制器与控制组件电性连接,用于基于电池包的状态参数,控制控制组件堵塞喷淋组件与第一冷却液管路、第二冷却液管路之间的通路,或将第一冷却液管路和/或第二冷却液管路中的冷却液导入喷淋组件。电池包发生热失控现象时,控制组件可以抽取车辆原有的第一冷却系统和/或第二冷却系统中的冷却液对电池包进行喷淋降温,而不需要单独的冷却液储藏罐,减少了电池包热失控处理系统对车辆内部空间的占用。
