Abstract

A method for air conditioning an electric or hybrid vehicle includes preconditioning a high voltage accumulator of the electric or hybrid vehicle. The electric or hybrid vehicle has an interior and the high voltage accumulator is air conditioned with an air-conditioning unit having a determined cooling potential. The high voltage accumulator has a current HVS temperature. The interior has a current interior temperature. During the preconditioning, the high voltage accumulator is supercooled in a preconditioning mode with the air-conditioning unit to an HVS temperature that is below an HVS operating temperature.
