Abstract
A battery charging apparatus includes a battery compartment having a receptacle that is configured to receive a battery pack. The battery charging apparatus includes a first heat exchange module and/or a second heat exchange module. The first heat exchange module includes a plenum surrounding the receptacle, where the plenum includes a chamber to receive a fluid. The plenum also includes a plurality of flow guides disposed in the chamber to define a variable flow passage for the fluid. The second heat exchange module includes a battery connector and a heat sink thermally coupled to the battery connector. The heat sink is arranged to dissipate thermal energy from the battery pack.
