Abstract
A heat pump cooling and heating system for an electric vehicle includes a range extending PCM heat exchanger (), with a single acting phase change material with a melt temperature between the two comfort temperatures associated with cooling and heating, respectively. In a charging mode, as the vehicle batteries are charged, the same exterior current source runs the compressor (), charging the PCM exchanger () with heat or 'cold.' During an initial range extending mode, the PCM exchanger/reservoir () serves as the heat source or heat sink. The PCM material does not directly heat or cool the air, as is conventional, allowing a single reservoir material to be used in both heating and cooling modes.
