The invention relates to a method for cooling an electric or hybrid vehicle battery, in which method the following steps are implemented: - determining a theoretical curve of thermal power (102) dissipated by the battery as a function of time during continuous charging of the battery and the duration of charging; - determining the maximum thermal power dissipated by the battery during charging; - determining a maximum cooling power (106) of a battery cooling device; - determining a theoretical maximum temperature reached by the battery during charging; - comparing the maximum cooling power (106) with the maximum thermal power dissipated by the battery; - and then charging the battery and, depending on the comparison, imposing a cooling power on the cooling device according to one or more successive stages of decreasing rotational speeds of the compressor.
