Abstract:
1. A method of controlling charging of an onboard energy storage system of a plug-in vehicle, the method comprising: wirelessly receiving, from the plug-in vehicle and using a cellular network service, a charge request for the onboard energy storage system, wherein the charge request is wirelessly received at a remote vehicle telematics system that supports bidirectional wireless data transfer with the plug-in vehicle; obtaining vehicle location data that indicates a location of the plug-in vehicle, the vehicle location data conveyed in the charge request; identifying, based on the vehicle location data, a power grid architecture to which the plug-in vehicle is connected; analyzing current power loading conditions for the power grid architecture; determining, from the charge request and the current power loading conditions, whether to charge the onboard energy storage system; and in response to the determining step, transmitting charge commands to the plug-in vehicle using the cellular network service, the charge commands comprising data that regulates charging of the onboard energy storage system, wherein the charge commands are influenced by the vehicle location data and by the current power loading conditions for the power grid architecture.
