The invention relates to a method for cooling a battery (12) of a motor vehicle (30) comprising a plurality of battery cells (10, 10a, 10b) by means of at least one cooling device (14) through which a coolant can flow and which is part of at least one cooling circuit (24) through which the coolant can flow and which comprises at least one coolant pump (26) which, in an active state (a), circulates the coolant, which is located in the at least one cooling circuit (24), in the cooling circuit (24). According to the invention, a control device (40) controls the at least one coolant pump (26) on the basis of the detection (D) of a fault (F) relating to the thermal runaway of at least one of the battery cells (10, 10a, 10b) of the battery (12) such that, if the fault (F) is detected, the at least one coolant pump (26) is activated or is operated so as to remain in the active state.
