Abstract
A method for operating a motor vehicle with a cooling system for cooling a traction battery may include receiving trip data representative of a planned route, reading in operating parameters of the traction battery, evaluating the trip data and the operating parameters to determine a set of data representative of a forecast temperature profile of the battery temperature, evaluating the set of data for the forecast temperature profile of the battery temperature to determine a phase of particularly high demand for cooling output while completing the route, buffer-storing (reducing) thermal energy while traveling the planned route by operating or increasing operation of the cooling system in anticipation of the high battery load to utilize heat storage capacity of the traction battery before the phase of particularly high cooling output demand.
