APPARATUS AND METHOD FOR RAPID CHARGING USING SHARED POWER ELECTRONICS
First Claim
1. A vehicle comprising:
- a DC bus couplable to an external charging source;
an electromechanical device coupled to at least one drive wheel;
an energy storage device coupled to the DC bus;
at least one contactor configured to selectively couple the electromechanical device and the energy storage device; and
a controller programmed to, upon entering a charging mode, wherein the DC bus is connected to the external charging source, open the at least one contactor to electrically decouple the electromechanical device from the energy storage device.

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.
