Abstract
The described method and system allows for the utilization of a telematics unit on a telematics-equipped vehicle to prevent the unauthorized discharge of a vehicle battery. A user may communicate an authorization request for allowing discharge of the vehicle battery through a telematics unit or telematics service provider (TSP) call center. If approved by the TSP call enter or telematics unit, an authorization, which may include an authorization code, is communicated to a charge controller which controls the discharge of the vehicle battery. Alternatively, the user may communicate an authorization code directly to the telematics unit which passes it on to the charge controller for approval.
