Abstract

A method to electrically charge an energy storage device (ESD) includes a step of electrically charging the ESD with energy transmitted through a regenerative braking electrical circuit (RBEC) disposed on vehicle by an electrical charging system (ECS) in electrical connection therewith. The ESD may be electrically charged by the ECS or a motor/generator that is also in electrical communication with the RBEC. The method also includes another step of electrically transmitting energy from the ESD through the RBEC and the ECS to supply energy to a power grid disposed external to the vehicle. An ECS for electrically charging an ESD is also presented that includes a first transducer, a second transducer that wirelessly receives energy from the first transducer, a motor/generator, and at least one electrical component which receives energy from the second transducer or energy from the motor/generator to electrically charge the ESD.
