Abstract
In one embodiment, an apparatus includes a power source and a moveable charging arm coupled to the power source and comprising a charging plate for contact with an electric vehicle contact plate. The charging arm is operable to transmit direct current (DC) pulse power with testing performed between high voltage pulses directly from the charging plate to the electric vehicle contact plate to charge one or more batteries at the electric vehicle. A method for charging the electric vehicle is also disclosed herein.
Claims24
An apparatus comprising:
- a power source;
- and
- a moveable charging arm coupled to the power source and comprising a charging plate for contact with an electric vehicle contact plate;
- wherein the charging arm is operable to transmit direct current (DC) pulse power with testing performed between high voltage pulses directly from the charging plate to the electric vehicle contact plate to charge one or more batteries at the electric vehicle.
An electric vehicle system comprising:
- a power system for charging a battery installed in an electric vehicle;
- and
- a contact plate for positioning on an exterior surface of the electric vehicle and transmitting power to the power system;
- wherein the contact plate is configured for receiving pulse power comprising a plurality of high voltage pulses with safety testing between said high voltage pulses, directly from a charging plate coupled to a charging arm at a charging station and transmitting the pulse power to the power system.
A method comprising:
- identifying an electric vehicle in a charging station;
- automatically positioning a charging arm in contact with a contact plate on an exterior surface of the electric vehicle;
- verifying compatibility of a power system at the electric vehicle with fault managed power;
- performing authentication between the charging station and the electric vehicle;
- and
- charging a battery at the electric vehicle with the fault managed power.
