Abstract

A charge calculation apparatus, system and method allow for a controller to administer an electric power charging operation to one or more client devices, such as an electric vehicle. The vehicle provides its ID to the controller, which in turn calculates a tax according to the vehicle making the request, and other factors such as taxing jurisdiction, amount of electricity used, timing, etc. By controlling the charging operation in this way, the taxing authorities are able to collect tax revenue for use in maintaining roads from the users of those roads by monitoring which vehicles are using electricity to operate the vehicles on the roads. By keeping track of the vehicle'"'"'s movement within different tax jurisdictions, the tax may be apportioned amongst the different taxing authorities.

Claims

1. An electric charging controller, comprising:

circuitry configured to

store, in a memory of the electric charging controller, a plurality of IDs of a plurality of external devices, each ID of the plurality of IDs uniquely identifying each external device of the plurality of external devices;

receive, from an external device of the plurality of external devices, an ID of the external device;

determine whether the received ID of the external device is stored in the memory;

control charging of the external device from a power server that receives power from a non-power-grid source in a case where it is determined that the received ID of the external device is stored in the memory; and

inquire of an external server about the received ID in a case where it is determined that the received ID of the external device is not stored in the memory.
