System and method for estimating a charge load
First Claim
1. A computing device for estimating a charge load and a charge time for at least one electric vehicle, said computing device configured to:
- store, in a first database coupled to said computing device, charging characteristics associated with the at least one electric vehicle;
receive, from a first of the at least one electric vehicle, a state of charge of the first electric vehicle and a vehicle identification of the first electric vehicle;
determine a location of the first electric vehicle;
determine whether charging characteristics associated with the first electric vehicle are stored in the first database, the charging characteristics associated with the first electric vehicle including at least one of a vehicle make, a vehicle model, a battery energy capacity, and a charger power capacity of the first electric vehicle;
query a second database using the vehicle identification to retrieve the charging characteristics associated with the first electric vehicle from the second database when the computing device determines that the charging characteristics associated with the first electric vehicle are not stored in the first database;
determine an estimated peak charge time and an estimated peak charge load based on the charging characteristics associated with the first electric vehicle and the state of charge of the first electric vehicle;
determine whether the first electric vehicle is authorized to charge based at least on the estimated peak charge time, the estimated peak charge load, the location of the first electric vehicle, and an energy demand on a transformer that provides electricity to a first charging station at the location of the first electric vehicle;
instruct the first charging station to charge the first electric vehicle at a first power level, when the computing device determines that the first electric vehicle is authorized to charge; and
one of (i) instruct the first charging station to charge the first electric vehicle at a second, reduced power level, and (ii) instruct the first charging station to not charge the first electric vehicle, when the computing device determines that the first electric vehicle is not authorized to charge.

Abstract
A computing device for estimating a charge load and a charge time for at least one electric vehicle is described. The computing device is configured to store, in a database coupled to the computing device, charging characteristics associated with a first vehicle of the at least one electric vehicle. The computing device is also configured to receive, from the first electric vehicle, a state of charge of the first electric vehicle, determine an estimated peak charge time and an estimated peak charge load based on the charging characteristics associated with the first electric vehicle and the state of charge of the first electric vehicle, and facilitate determining whether the first electric vehicle is authorized to charge based at least on the estimated peak charge time and the estimated peak charge load.
