ENERGY USE AGGREGATION AND CHARGE CONTROL OF A PLUG-IN ELECTRIC VEHICLE
First Claim
1. A vehicle charging network comprising:
- a vehicle having a rechargeable battery pack and a vehicle telematics unit (VTU); and
a server having a processor, memory, and a transceiver in communication with the VTU, wherein the server is in communication with a remote client device and is programmed to;
receive vehicle information from the VTU via the transceiver, including a location of the vehicle and an amount of electrical charging power delivered to the battery pack during an active charging event;
transmit charging control signals to the VTU in response to a load adjustment request from the remote client device to thereby cause the VTU to control the active charging event and at least partially satisfy the load adjustment request;
record, as an energy throughput value, the amount of electrical charging power delivered to the vehicle over time for a plurality of the active charging events;
aggregate a plurality of the recorded energy throughput values over a calibrated duration or a calibrated number of prior active charging events; and
generate output data describing the aggregated energy throughput values.

Abstract
A network includes vehicle(s) having a battery pack and vehicle telematics unit (VTU), and a server. A server in communication with the VTUs and remote client device(s) is programmed to receive vehicle information from the VTU, including an energy throughput value defined by charging power delivered to the battery pack during an active charging event. The server receives utility information and a load adjustment request from the remote client device, including a power interrupt permission status describing whether interruption of power by a host of the client device is permitted. Charging control signals are transmitted in response to the load adjustment request to enable or postpone the charging event. Energy throughput is recorded over multiple active charging events, which are then combined or aggregated. Output data, e.g., a bill or report describing the aggregated energy throughput values, may be generated by the server. A method and server are also disclosed.

10. A method comprising:
-
receiving, via a server, vehicle information from a vehicle telematics unit (VTU) of a vehicle having a battery pack, including a location of the vehicle and an amount of electrical charging power delivered to the battery pack during an active charging event; receiving a load adjustment request from a remote client device; transmitting charging control signals to the VTU in response to the load adjustment request to thereby cause the VTU to control the active charging event and at least partially satisfy the load adjustment request; determining, as an energy throughput value, the amount of electrical charging power delivered to the vehicle over time for a plurality of the active charging events; aggregating, via the server, a plurality of the recorded energy throughput values over a calibrated duration or a calibrated number of prior active charging events; and generating output data, via the server, describing the aggregated energy throughput values. - View Dependent Claims (11, 12, 13, 14, 15)

16. A server for a vehicle charging network having a plurality of remote client devices and a plug-in electric vehicle having a rechargeable battery pack and a vehicle telematics unit (VTU), the server comprising:
-
a processor; memory; and a transceiver in communication with the VTU, wherein the server is in communication with the remote client devices and is programmed to; receive vehicle information from the VTU, including a location of the vehicles and a corresponding state of charge and charging status of the battery pack; receive a load adjustment request from at least one of the client devices; change a setting of a charging timer of the vehicle remotely via transmission of charging control signals to the VTU in response to the received load adjustment request to thereby postpone or enable charging of the battery pack; determine an energy throughput value at each of a plurality of active charging events using the vehicle information from the VTU, wherein the energy throughput value defines an amount of charging power delivered to the battery pack during a corresponding one of the active charging events; aggregate the determined energy throughput values over a calibrated duration; and generate output data describing the aggregated energy throughput values. - View Dependent Claims (17, 18, 19, 20)
