Power grid load management for plug-in vehicles
First Claim
1. A method of controlling charging of an onboard energy storage system of a plug-in vehicle, the method comprising:
- obtaining, at the plug-in vehicle, vehicle location data that indicates a location of the plug-in vehicle;
wirelessly transmitting a charge request for the onboard energy storage system using a cellular network service, the charge request transmitted from the plug-in vehicle to a remote vehicle telematics system that supports bidirectional wireless data transfer with the plug-in vehicle, the charge request conveying the vehicle location data;
wirelessly receiving, the cellular network service, charge commands from the remote vehicle telematics system in response to the charge request; and
regulating charging of the onboard energy storage system in accordance with the charge commands, wherein the vehicle location data conveyed in the charge request enables the remote vehicle telematics system to determine a power grid architecture to which the plug-in vehicle is connected, and wherein the charge commands are influenced by the vehicle location data and by current power loading conditions for the power grid architecture.

Abstract
Methods and systems are provided for controlling the charging of an onboard energy storage system of a plug-in vehicle using a remote command center, such as a vehicle telematics service. An embodiment of such a method involves the transmission of a charge request for the onboard energy storage system to a remote command center associated with the plug-in vehicle. In response to the charge request, a charge command is received from the remote command center. The charging of the onboard energy storage system is regulated in accordance with the received charge command, which may be a charge enable command or a charge disable command.

12. A method of controlling charging of an onboard energy storage system of a plug-in vehicle, the method comprising:
-
obtaining vehicle location data with a global positioning system onboard the plug-in vehicle, the vehicle location data indicating a location of the plug-in vehicle; wirelessly transmitting a charge request for the onboard energy storage system, the charge request transmitted from the plug-in vehicle to a remote vehicle telematics system that supports bidirectional wireless data transfer with the plug-in vehicle, and the charge request conveying the vehicle location data; in response to wirelessly transmitting the charge request, wirelessly receiving charge enable and charge disable commands at the plug-in vehicle, wherein the vehicle location data conveyed in the charge request enables the remote vehicle telematics system to determine a power grid architecture to which the plug-in vehicle is connected, and wherein the charge enable and disable commands are influenced by the vehicle location data and by current power loading conditions for the power grid architecture; and enabling and disabling charging of the onboard energy storage system in accordance with the charge enable and disable commands.
