APPARATUS AND METHOD FOR RAPID CHARGING USING SHARED POWER ELECTRONICS
First Claim
1. A vehicle charging system comprising:
- an energy storage device;
a DC/DC converter coupleable to the energy storage device;
a traction drive coupleable to the DC/DC converter, the traction drive comprising an inverter coupled to a traction motor; and
at least one switching device coupled between the traction drive and the energy storage device, the switching device configured to selectively decouple the traction drive from the energy storage device when the energy storage device is being charged from an external charging source.

Abstract
An apparatus comprises a power electronic energy conversion system comprising a first energy storage device configured to store DC energy and a first voltage converter configured to convert a second voltage from a remote power supply into a first charging voltage configured to charge the first energy storage device. The apparatus also includes a first controller configured to control the first voltage converter to convert the second voltage into the first charging voltage and to provide the first charging voltage to the first energy storage device during a charging mode of operation and communicate with a second controller located remotely from the power electronic energy conversion system to cause a second charging voltage to be provided to the first energy storage device during the charging mode of operation to rapidly charge the first energy storage device.
