Method and Apparatus for High-Voltage DC Charging of Battery-Electric and Plug-in Hybrid Electric Vehicles
First Claim
1. A system, comprising:
- a donor energy storage device (ESD) at a donor electric vehicle;
a recipient ESD at a receiving electric vehicle; and
a portable cross electric vehicle charger (PxEVC) configured to controllably transfer power from said donor ESD to said receiving ESD.

Abstract
A portable charging device can provide controllable fast DC charging of an electric vehicle (EV) high voltage battery by a separate EV high voltage battery. The charging device can be configured to comply with universal standards for EV charging so as to be compatible with various automobile models of various manufacturers. The device can be configured to establish a communication link with a donor and recipient vehicle and conduct a voltage matching process between the batteries of the two vehicles prior to transferring power to the recipient vehicle battery. To prevent energy theft, control of a charging process can be shared among the charging device and the donor and receiver vehicles. A charger device can be configured to enable a charging process only when no faults are detected. A charger device can allow a motorist to quickly recharge a depleted high voltage battery at a convenient time and location.
