In a coolant temperature control (1) for regulating the coolant temperature of a power converter of an electrically driven vehicle, in particular an electrical locomotive, the coolant temperature is regulated to a set value (16) that is independent from the current ambient temperature in order to increase the life of the used high-performance traction power converters. As a result, the components are subject to less drastic temperature load alternations.
