1. A method for determining a maximum value for a parameter range of a driving operation parameter of a motor vehicle, wherein the motor vehicle comprises a control device, a traction motor, an energy storage device, and a temperature sensor, the method comprising:
determining, with the temperature sensor, a temperature of the energy storage device;
determining, with a control device, whether a predicted temperature of the energy storage device lies within a charging temperature range, wherein the charging temperature range is a subrange of an operating temperature range and includes at least one temperature with a charging power maximum for charging the energy storage device;
displaying, with a display device, a difference between a predicted charging duration for a temperature within the charging temperature range and a predicted charging duration for a temperature above the charging temperature range but within the operating temperature range; and
throttling, with the control device, a speed of the motor vehicle to reduce a temperature of the energy storage device within the charging temperature range.
