Abstract
An Electric Vehicle Supply Equipment (EVSE) charging system that can simultaneously deliver both Alternating Current (AC) and Direct Current (DC) power to Plug-in Electric Vehicle's (PEV) AC voltage bus and DC voltage bus, respectively. Either a Combined Charging System (CCS) coupler or separate paired AC and DC couplers provide the connection between the EVSE's vehicle connector(s) and the PEV's inlet(s). The EVSE is configured to simultaneously supply AC and DC power to the vehicle when connected to the PEV. The EVSE coupler(s) facilitate communication between a PEV and the EVSE charging system when connected to the charging inlet(s) of the PEV. Connection of the AC voltage bus to the PEV is controlled by one or more relays, while and connection of the DC voltage bus to the PEV is controlled by operation of an Offboard Charging Module (OBCM).
