Abstract: The concepts described herein provide a system and associated charging connector that is capable of offloading electric power stored in a rechargeable energy storage system (RESS) of an electrified vehicle to supply electric power to a stationary system, e.g., a residential dwelling or a business site, upon occurrence of a power outage in an electric power grid that supplies electric power to the stationary system. This includes the charging connector being capable of offloading electric power under conditions in which the RESS of the electrified vehicle is initially disconnected from the charging connector when the power outage occurs. This concept enables an electrified vehicle to supply electric power to a stationary system when connecting after a delay period subsequent to the power outage.

Abstract: A split-phase bidirectional on-board charger (OBC) has separate charging and discharging modes, and includes a switchgear block connectable to an offboard charging station during the charging mode, and to an external alternating current (AC) load during the discharging mode. The OBC includes first and second DC-AC converters connected to the switchgear block and DC-DC converter connected to the first and second DC-AC converters and a DC bus. During the charging mode, the DC-AC converters output a DC link voltage to the DC-DC converter. The DC-DC converter outputs a DC charging voltage or current to the DC bus when the link voltage reaches a predetermined value. During the discharging mode, the DC-AC converters receive a DC discharging voltage or current from the DC-DC converter and together selectively output a split-phase AC voltage through the switchgear block to the AC electrical load.

Abstract: A system for charging an electric vehicle in a facility includes a current sensor adapted to obtain an input current signal for a power source in the facility. An electric vehicle supply equipment (EVSE) is configured to charge the electric vehicle through the power source based at least partially on a control pilot signal. A controller has a processor and tangible, non-transitory memory on which instructions are recorded for dynamically adjusting the control pilot signal based on the input current signal. The control pilot signal is set to a predefined maximum when the input current signal is less than a main circuit breaker rating of the facility. The controller is configured to reduce the control pilot signal from the predefined maximum when the input current signal is at or above the main circuit breaker rating.

Abstract: An electrical system can include a rechargeable energy storage system (RESS) and a direct current to direct current (DC-DC) converter. The DC-DC converter is connected to the RESS and configured to connect to a DC charging station. The DC-DC converter is configured to selectively connect the RESS to the DC charging station such that a charging current is selectively provided to the RESS during a recharging operation.
