PRESSURE EQUALIZATION TANK FOR A COOLANT SYSTEM OF AN ELECTRICALLY DRIVEN MOTOR VEHICLE

The invention relates to a pressure equalization tank (110) for a coolant system (100) of an electrically driven motor vehicle (1), comprising: - a first partial volume (110a) filled with pressurized gas, - a second partial volume (110b) filled with a coolant, - an electronically controlled valve (128) operable to release pressurized gas from the pressure equalization tank (110) when the coolant pressure exceeds a threshold value.
