A method for operating a motor vehicle, which is driven by an electric motor. The motor vehicle has a high-voltage power system, to which the electric motor is connected, with a high-voltage battery that is operated in an operating temperature range, for which purpose, a temperature control mechanism utilizing a circulating coolant, and having a heating mechanism for the coolant and a cooling mechanism for the coolant is assigned to the high-voltage battery, to satisfy a power deficiency which indicates that a braking power required by recuperation of the electric motor exceeds the on-demand power currently in the high-voltage power system that can be demanded for charging the high-voltage battery.

A method for charging an accumulator of an electrically drivable motor vehicle, wherein a cooling device of the motor vehicle is operated in order to cool the accumulator during the charging of the accumulator, wherein the motor vehicle emits noise in dependence on the cooling power of the cooling device, including the steps: determining positional data for a position of the motor vehicle during charging, determining a maximum value for a noise emission on the basis of the positional data and while taking into account noise emission positional data, and taking into account the maximum value for noise emission with respect to the charging of the accumulator.
