According to the whole vehicle thermal runaway control system, when a power supply device unit of a high-voltage power supply module is subjected to thermal runaway, the system is controlled by a control module; when the power supply device unit is subjected to thermal runaway, the circuit breaking device unit connected with the corresponding power supply device unit subjected to thermal runaway is disconnected, the first switch unit connected with the corresponding power supply device unit subjected to thermal runaway continues to be disconnected, other first switch units are closed, and the second switch unit and the third switch unit are controlled to be disconnected; the power supply device unit corresponding to the thermal runaway is isolated; the voltage output by the remaining power supply device units which normally supply power is input to the first voltage transformation module, so that the voltage is boosted to a normal high-voltage first refrigeration module for power supply, the voltage required by normal work of the first refrigeration module is maintained, the first refrigeration module is started for refrigeration, the power of the electric drive assembly module is controlled, and the power of the electric drive assembly module is controlled. And the temperature is reduced to zero within the preset time.

    本发明提供一种整车热失控控制系统,当高压供电模块的供电装置单元发生热失控时,该系统在控制模块的控制下,断开与对应发生热失控的供电装置单元相连的断路装置单元且与对应的热失控的所述供电装置单元相连的第一开关单元继续断开,其他第一开关单元闭合,并控制所述第二开关单元以及所述第三开关单元断开,以隔离对应所述热失控的所述供电装置单元;并将剩余正常供电的供电装置单元输出的电压输入到第一变压模块,使其升压到正常高电压第一制冷模块进行供电,以维持所述第一制冷模块正常工作所需电压,并启动所述第一制冷模块进行制冷,且控制所述电驱总成模块的功率,使其在预设时间内降低为零。
