Charge Control System For Mobile Energy Storage Fleet
Vehicle control systems can include one or more location sensors, an energy storage device, one or more charge sensors and one or more vehicle computing devices. The location sensor(s) can determine a current location of a vehicle, while the charge sensor(s) can determine a current state of charge of an energy storage device that can be located onboard the vehicle to provide operating power for one or more vehicle systems. The vehicle computing device(s) can communicate the current location of the vehicle and current state of charge of the energy storage device to a remote computing device, receive from the remote computing device a charging control signal determined, at least in part, from the current location of the vehicle and the current state of charge of the energy storage device, and control charging of the energy storage device in accordance with the charging control signal.

- 1-15. (canceled)
- 16. A charging structure, comprising:
a plurality of charging stations configured to electrically couple to plurality of energy storage devices for use with a fleet of vehicles; an energy transfer system configured to interface with the plurality of energy storage devices at the plurality of charging stations and selectively charge the plurality of energy storage devices; a charge controller coupled to the energy transfer system and configured to:
determine, by one or more computing devices, a sensed state of charge for each energy storage device; and
control, by the one or more computing devices, charge of each energy storage device in accordance with one or more charging control signals, wherein the charging control signals are determined, at least in part, from the sensed state of charge for each energy storage device and one or more electric grid signals indicating current status or power pricing information for an electric grid.
- 25. A charging structure, comprising:
a vehicle track along which a plurality of vehicles are selectively maneuvered through the charging structure; a plurality of charging stations provided in predetermined locations along the vehicle track, each charging station comprising:
a vehicle platform configured to receive a vehicle of the plurality of vehicles and maneuver the vehicle along the vehicle track; and
an energy transfer system configured to interface with an energy storage device associated with the vehicle and selectively charge the energy storage device;
one or more ingress access points for entering the charging structure; one or more egress access points for exiting the charging structure; and a charge controller configured to implement one or more charging control signals, wherein the charging control signals control a charge of each energy storage device, instruct the plurality of vehicles to enter the charging structure at the one or more ingress access points, navigate through the charging structure, and exit the charging structure at the one or more egress access points upon attaining a target state of charge for the energy storage device.
- 34. A charging structure, comprising:
a plurality of charging stations, each charging station configured to provide a receptacle for electrically coupling to an energy storage device; one or more energy transfer systems configured to interface with and selectively charge each energy storage device; a charge controller coupled to the energy transfer system and configured to:
determine a current state of charge for each energy storage device currently provided within the charging structure;
control the charge of each energy storage device in accordance with one or more charging control signals; and
generate an identification signal to provide to a vehicle arriving at the charging structure indicating an energy storage device within the plurality of charging stations to swap with a current energy storage device within the vehicle.
