The method involves determining a future route peak loads of a cooling circuit (3) by a controlling- and regulating-unit (2). The driving distance-based time is ahead before the peak loads of the cooling circuit by a heat exchanger in the cooling circuit. The additional cooling power is fed into a system such that the services provided by an electromobility component (1) is optimized and a maximum temperature of the electric mobility component does not exceed after passing through a route. An independent claim is included for an arrangement for optimizing the motor availability of an electromobility component of a drive power cooled by a cooling circuit in a motor vehicle, particularly utility vehicle.
