The invention relates to the technical field of power batteries, in particular to a thermal runaway suppression device and method for a power battery, and the device comprises a detection module which is used for detecting whether the thermal runaway of the power battery occurs or not; the cooling module is used for outputting a cooling medium; the at least one transmission pipeline is correspondingly arranged between the plurality of battery modules of the power battery and the cooling module; and the control module is used for opening the corresponding transmission pipeline under the condition that the detection module detects that any battery module of the power battery is subjected to thermal runaway, so that the battery module subjected to thermal runaway is cooled by using the cooling medium until a preset suppression condition is met. The battery module can be accurately detected, when the power battery is in thermal runaway, only the battery module related to thermal runaway in the power battery needs to be replaced, the whole battery pack does not need to be replaced, economic losses caused by thermal runaway can be reduced to the maximum extent, and the safety of a vehicle and a user is effectively guaranteed.

    本申请涉及动力电池技术领域,特别涉及一种动力电池的热失控抑制装置及方法,其中,装置包括:检测模块,用于检测动力电池是否发生热失控;降温模块,用于输出降温介质;至少一个传输管道,至少一个传输管道对应设置于动力电池的多个电池模组和降温模块之间;控制模块,用于在检测模块检测到动力电池的任一电池模组发生热失控的情况下,开启对应的传输管道,以利用降温介质对发生热失控的电池模组进行降温,直至达到预设抑制条件。本申请可以精准到电池模组,当动力电池热失控后,可以只更换动力电池中热失控的相关电池模组,无需更换整个电池包,可以最大限度的降低热失控带来的经济损失,有效保障车辆及用户的安全。
