The invention relates to a method for cooling a battery (12) of a motor vehicle (30), comprising a plurality of cells (10, 10a, 10b), by means of a cooling device (14), through which a cooling medium can flow, as part of at least one cooling circuit (24) through which the cooling medium can flow, said cooling circuit comprising at least one cooling medium pump (26), the cooling medium pump circulates a cooling medium located in at least one cooling circuit (24) in the cooling circuit (24) in an activated state (a). In this case, the control device (40) controls the at least one cooling medium pump (26) on the basis of a detection (D) of a fault situation (F) that is dependent on a thermal runaway of at least one of the cells (10, 10a, 10b), such that, upon detection of the fault situation (F), the at least one cooling medium pump (26) is activated or the at least one cooling medium pump (26) continues to operate in the activated state.
本发明涉及一种用于借助于作为至少一个可被冷却介质通流的冷却回路(24)的一部分的、可被冷却介质通流的冷却设备(14)对机动车(30)的电池(12)进行冷却的方法,所述电池包括多个电芯(10、10a、10b),所述冷却回路包括至少一个冷却介质泵(26),所述冷却介质泵在激活状态(a)下使位于至少一个冷却回路(24)中的冷却介质在冷却回路(24)中循环。在此,控制设备(40)根据对与电芯(10、10a、10b)中的至少一个电芯的热失控相关的故障情况(F)的检测(D)来控制至少一个冷却介质泵(26),从而在检测到故障情况(F)时,激活至少一个冷却介质泵(26)或者使至少一个冷却介质泵(26)继续在激活状态中运行。
