Abstract: Devices, methods and software for automated electrical connector positioning for electric vehicle (EV) charging are provided. Using, for example, the disclosed automatic charging device, a method for charging an EV includes determining receipt of an EV-side electrical connector to a charging zone of an EV charging environment. The method includes actuating a charger-side electrical connector from an initial position outside of the charging zone to a final position inside of the charging zone. The final position corresponds to the charger-side electrical connector matingly engaged with the EV-side electrical connector.

Abstract: A protective arrangement for an electric vehicle charging system includes a floor unit forming a recess and a linkage disposed in the recess. The linkage is extendable from the recess from a stowed position to an extended position. A cleaning device is disposed to discourage accumulation of debris into the recess and on the linkage when the linkage is in the stowed position.

Abstract: A charging connection is provided for charging electric vehicles. The first connector is coupled to an electric charging station with an electric cable. The second connector is coupled to the electric vehicle. The first connector has at least two openings slide onto at least two posts of the second connector. When the first and second connectors are coupled together, an electric potential supplies power from the first connector to the second connector.

Abstract: A system for charging commercial electric vehicles, including buses and trucks. The system can include a charging station that outputs a supply of relatively high voltage electrical power, and a cable suspension post having a support post and a suspension arm. The suspension arm can be suspended away from the support post at a vertical height that is higher than the height of typical commercial vehicles. At least a portion of a charging cable is electrically coupled to the charging station and suspended from the suspension arm. A charging connector can be free-hanging from the suspended portion of the charging cable, and therefore be swingingly displaceable into electrical engagement with a mating connector of the vehicle. The suspension arm can be rotatably displaced relative to the support post and/or another portion of the suspension arm such that a vertical height and/or other position of the suspended arm can be adjusted.

Abstract: Systems, methods and software for automated electrical connector positioning for electric vehicle (EV) charging are provided. Using, for example, the disclosed automatic charging device, a method for charging an EV includes capturing an image of at least a portion of a pattern positioned in a fixed location in a landing zone of an EV-side electrical connector in a fixed position on or in an underside of the EV. The method includes determining, based on the image, a displacement of a charger-side electrical connector from an initial position to a final position, the final position corresponding to the charger-side electrical connector matingly engaged with the EV-side electrical connector. The method includes actuating the charger-side electrical connector from the initial position to the final position according to the displacement.

Abstract: A charge head is connected to a charge inlet of an electric vehicle to supply an electric charge to recharge the battery of the vehicle. The charge head is attached to a connecting device that moves the charge head to the charge inlet. A sensor is provided to sense the locations of the tires of the vehicle. The system then uses the relative location of the charge inlet to the tires to determine the location of the charge inlet in order to move the charge head.

Abstract: A method and apparatus for automatic charging of electric vehicles in which a plug head of a charging unit is automatically received in a receiving compartment of a vehicle charger actuation device. A push wall of the vehicle charger actuation device is displaced into contact the plug head in a manner that facilitates rotation of the plug head into angular alignment with the plug head receptacle. The charging unit can align a position of the plug head with the plug head receptacle such that continued displacement of the push wall displaces the plug head to a position at which the plug head is electrically coupled to the plug head receptacle. After a charging event, the push wall moves away from the plug head receptacle and engages a pull rod that is coupled to a pin skirt such that the pin skirt is displaced in a direction that ejects the plug head from the plug head receptacle.

Abstract: An automatic charging device and method is described that is positionable to access an underside of an electrical vehicle that facilitates hands-free connection of a vehicle-side electrical connector with a floor unit electrical connector. The automatic charging device includes a floor unit, a first slidable carriage disposed in the floor unit, a second slidable carriage disposed in the floor unit, a pivotal link coupled to the floor unit electrical connector, and a lift mechanism connected to the second slidable carriage and the pivotal link. The floor unit electrical connector is arranged to rise away from the floor unit in a direction of the vehicle-side electrical connector to facilitate a mating of the vehicle-side electrical connector and the floor unit electrical connector. The first and the second slidable carriages are configured to move in a linear xy-direction, respectively, and the lift mechanism is configured to move in a linear z-direction.

The charge head is attached to a connecting device that moves the charge head to the charge inlet. A sensor is provided to sense the locations of the tires of the vehicle. The system then uses the relative location of the charge inlet to the tires to determine the location of the charge inlet in order to move the charge head.

Abstract: A charging station for automatically conductively charging an electric vehicle having an underbody receptacle cavity is provided. When charging, the charging station and the electric vehicle may spaced apart by a linear distance. Other alignment discrepancies may also exist between the electric vehicle and the charging station. To traverse the linear distance and align and insert the plug into the receptacle, the charging station may be capable of moving in multiple translational degrees of freedom.

Abstract: Systems and method for underside charging of electric vehicles (EVs) are provided. With the EV positioned in a charging environment having a ground surface, a floor unit device actuates an electrical connector toward a charge receptacle of an EV vehicle unit, and the vehicle unit actuates the charge receptacle toward the electrical connector. The actuation facilitates coupling between the connector and the charge receptacle. A flow of electrical current is initiated through the coupled connector and charge receptacle to charge the EV power storage device. Upon completion of the EV charging process, the electrical connector and the charge receptacle are actuated away from one another to facilitate decoupling therebetween.

In one form the vehicle includes a battery, such as a lithium-ion battery, capable of being charged with high powers. In some forms the battery can be charged with 1 MW, 2 MW, 3 MW and higher power transfers. The power inlet can include a door the coves a power receptacle useful to receive the connector, and a translatable carriage useful to define at least part of the power receptacle. In some forms a cover is included. The power receptacle can include a wall having a passage to permit the insertion of power connector pins, the wall moving with movement of the carriage. When the connector is inserted into the power receptacle, insertion of the pins can be made via relative movement of the pins on the vehicle side with passages in the connector.
