Apparatus for rapid charging using onboard power electronics and method of manufacturing same

摘要

An apparatus for rapid charging using onboard power electronics includes a DC bus, a first energy storage device coupled to the DC bus and configured to output a DC voltage, a first bi-directional voltage modification assembly coupled to the DC bus, and a high-impedance voltage source coupleable to the DC bus. The apparatus further includes a charging system having a first receptacle coupled to the DC bus and a second receptacle coupled to the first bi-directional voltage modification assembly. The first receptacle is constructed to mate with a first connector coupled to the high-impedance voltage source and the second receptacle is constructed to mate with a second connector coupled to the high-impedance voltage source. A controller is programmed to control a simultaneous transfer of charging energy through the first and second receptacles of the charging system to the DC bus.
