Abstract
A vehicle charging apparatus is described herein, which may include a battery pack comprising a plurality of individual batteries, a power input port receiving electrical power at a first wattage, an AC-to-DC conversion circuit configured to provide DC power to charge groups of batteries in the plurality of individual batteries, a power conversion circuit configured to condition a DC output of at least one group of batteries to provide a charging current output to a vehicle via a coupling, and a processing circuit configured to control the power conversion circuit to provide the charging current at a second wattage greater than the first wattage. The first wattage may be actively or inherently limited to a level less than the second wattage in order to provide fast DC charging with a limited power input.
