The Magic Charger is an onboard charging system for electric vehicles that would use the already available traction inverter in an E.V to charge its battery. To do this we leverage the bidirectional nature of the traction inverter by controlling the power flow into and out of the inverter. Using an electrically controlled contactor switch the inverter is set to either charge the onboard battery using the grid as a source, or power the vehicle’s motors from the battery. The design of the Magic Charger includes already available equipment in the E.V and only requires two contactor switches, a simple LC grid filter, and a microcontroller for full implementation.
