METHOD TO IMPROVE CHARGING SPEED USING ONBOARD ALTERNATING CURRENT GENERATION

A vehicle includes an electrical system performing a method of charging a battery of the vehicle. The electrical system includes the battery, an inverter coupled to the battery via a positive bus line, a first contactor within the inverter that connects the battery to the inverter via the positive bus line, a charge port for connecting the positive bus line to a charging station for receiving a baseline charging current from the charging station, a diode for preventing a reverse flow of current from the electrical system to the charging station, and a processor. The processor is configured to control the first contactor to generate a ripple current in the positive bus line, wherein the ripple current is superimposed over the baseline charging current to obtain a combined charging current, wherein the combined charging current is used to charge the battery.
