Abstract
A vehicle charging system includes a charging station comprising a controller configured to selectively supply power from a vehicle to a home. The controller enables charging in response to a predetermined minimum voltage and a predetermined minimum current on an electric vehicle supply equipment (EVSE) side of the charging station. A mobile battery station is configured to supply power from a plurality of batteries to the EVSE side of the charging station at a first voltage greater than or equal to the predetermined minimum voltage and a first current greater than the predetermined minimum current.
Claims18
A vehicle charging system comprising:
- a charging station comprising a controller configured to selectively supply power from a vehicle to a home,
- wherein the controller enables charging in response to a predetermined minimum voltage and a predetermined minimum current on an electric vehicle supply equipment (EVSE) side of the charging station;
- a mobile battery station configured to supply power from a plurality of batteries to the EVSE side of the charging station at a first voltage greater than or equal to the predetermined minimum voltage and a first current greater than the predetermined minimum current;
- a user interface configured to select one of a plurality of operating modes;
- and
- a DC-DC converter/charger configured to supply power from the plurality of batteries to a home inverter/rectifier/hub connected to the EVSE side of the charging station and to receive power from the home inverter/rectifier/hub to charge the plurality of batteries.
A method for operating a vehicle charging system comprising:
- providing a charging station comprising a controller configured to selectively supply power from a vehicle to a home,
- wherein the controller enables charging in response to a predetermined minimum voltage and a predetermined minimum current on an electric vehicle supply equipment (EVSE) side of the charging station;
- configuring a mobile battery station to supply power from a plurality of batteries to the EVSE side of the charging station at a first voltage greater than or equal to the predetermined minimum voltage and a first current greater than the predetermined minimum current;
- selecting one of a plurality of operating modes of the mobile battery station;
- supplying power from the plurality of batteries to a home inverter/rectifier/hub connected to the EVSE side of the charging station;
- and
- receiving power from the home inverter/rectifier/hub to charge the plurality of batteries.
A method for operating a vehicle charging system comprising:
