Classification: CPC B  H  Y | IPC B  H

Claim 8:
9. A bi-directional charger comprising:
a first portion configured to be coupled to an electrical grid;
a second portion configured to be coupled to an electric vehicle;
an enclosure comprising:
a first power stage configured for AC-to-DC conversion and coupled to the first portion, the first power stage comprising a first processor;
a second power stage configured for DC-to-DC conversion and coupled to the second portion, the second power stage comprising a second processor, wherein the second power stage is galvanically isolated; and
a third processor configured to:
communicate with the first processor to control the first power stage; and
communicate with the second processor to control the second power stage and manage communications with the electric vehicle, and

wherein the first power stage and second power stage are configured to operate based on a reactive power and an effective power, wherein the first power stage and second power stage are configured to perform:
inductive discharge of a battery of the electric vehicle when the reactive power is positive and the effective power is positive;
inductive charge of the battery of the electric vehicle when the reactive power is positive and effective power is negative;
capacitive charge of the battery of the electric vehicle when the reactive power is negative and the effective power is negative; and
capacitive discharge of the battery of the electric vehicle when the reactive power is negative and the effective power is positive.
