An electric vehicle fast charger and methods thereof are described, adapted for re-use of magnetic components of an electric vehicle having traction converters when the electric vehicle is stationary and connected to a power grid. A switching stage provided by one or more sets of switches is controlled complementarily with the switches of the traction converters to (i) provide inversion of a grid voltage and (ii) shape current of the grid current between the electric vehicle and the power grid to track a waveshape of the grid voltage. A single switching stage and a dual switching stage circuit are contemplated, along with switch controller circuits, and instruction sets for switch control. Variants provide for energy transfer to accommodate for energy imbalances between storage devices.
