Abstract

A method of managing power cell information resources of a non-petroleum fueled vehicle, particularly electric or fuel cell vehicles of a fleet of vehicles. Such vehicles have power pack instrumentation for wirelessly reporting data to a base station computer including power pack charge parameters and GPS location in real-time. This data is applied to a database which documents past vehicle performance as well as contains minimal acceptable vehicle parameters. A prediction is made regarding remaining range, state of charge and vehicle scheduling, considering vehicle load or mileage efficiency. The remaining range is viewed in combination with the GPS location of the vehicle so that judgments can be made regarding whether particular vehicles can take a job request, complete the job without recharging, then go to a recharging location, or have the vehicle dispatched for service.
