Abstract
A battery charging assembly for a vehicle includes a vehicle battery and a charging module electrically connected to the vehicle battery and configured to supply electrical energy to the battery. An energy harvesting module is electrically connected to the charging module. The energy harvesting module is configured to harvest energy, to convert the harvested energy to electrical energy and to supply the electrical energy to the charging module. A cooling circuit supplies a cooling fluid to the energy harvesting module to cool the energy harvesting module.
