Abstract
An electric vehicle includes a drive system that performs a method of transferring power between a vehicle and an external location. The drive system includes a battery, a rectifier, and a processor. The rectifier is one of a two-level rectifier and a multi-level rectifier. The processor is configured to connect the rectifier between an alternating current (AC) port of an outlet of an external location and the battery. The rectifier is configured to convert between an AC power at the AC port on an external side of the rectifier and a direct current (DC) power at a vehicle side of the rectifier in order to transfer power bi-directionally between the external location and the battery.
