A method for charging at least one electrical energy accumulator of a motor vehicle, in which electrical energy from a charging station external to the motor vehicle is transferred across a detachable electrical connection to the energy accumulator, while a cooling fluid is taken from the charging station across a detachable cooling fluid connection and by means of a delivery device to at least one cooling element of the motor vehicle, so that thermal energy is transferred from the energy accumulator across the cooling element to the cooling fluid and taken away by means of the cooling fluid, wherein a pressure in the cooling fluid or in a mixture consisting of the cooling fluid and a gas is reduced, before and/or during the supplying thereof to the cooling element, by means of at least one pressure reducing element, so that the boiling temperature of the cooling fluid is lowered such that it evaporates at least partly during the transfer of the thermal energy.
