Claim 0:
1. A heat recovery system for an electric vehicle, comprising first and second switchable heat sources and a controller operable to selectively switch one of the heat sources into thermal communication with a compressor in a thermodynamic cycling system, the thermodynamic cycling system being in thermal communication with a heat sink; and a detection means operable to detect a temperature differential between each of the switchable heat sources and a fluid entering the compressor;
wherein the controller is operable to switch one of the first and second switchable heat sources into thermal communication with the thermodynamic cycling system when a temperature differential is detected between the fluid entering the compressor in the thermodynamic cycling system and the switchable heat source, the compressor being operable to upgrade low grade heat from the switchable heat source to a higher grade heat upon operation of the compressor.
