Abstract
In a method and apparatus for the operation of a vehicle having a battery with a plurality of series or parallel connected individual cells, a coolant flows through the respective cell housings and/or a battery housing that encloses the entire battery. The coolant is delivered within a coolant circuit by a pump unit, and is thermally coupled with a refrigerant circuit through a heat exchanger. A refrigeration compressor placed in the refrigerant circuit is thermally coupled with the coolant circuit through the heat exchanger, depending on a current ambient temperature and/or a current speed of the vehicle. The speed of the refrigeration compressor may be regulated depending on the current ambient temperature and/or the current speed of the vehicle.
