Hereinafter, the first embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an example of a usage mode of the power billing system 1 of the present embodiment. The electric vehicle EV runs on the electric power stored in a power storage device (not shown) such as a secondary battery. The electric power stored in this power storage device decreases as the electric vehicle EV runs. Therefore, it is necessary to supply electric power from the outside of the electric vehicle EV to charge the power storage device. In the case of the example in the figure, the electric vehicle EV receives electric power for charging from the supply source SP. This electric vehicle EV is owned by the supplier UR. Here, the supply source SP and the supply destination UR are not the same person. That is, in the case of this example, the owner of the electric vehicle EV and the supplier supplying electric power to the electric vehicle EV are different.

Here, the supply source SP and the supply destination UR are both customers of the electric power company PC. The electric power company PC charges the supply source SP and the supply destination UR according to their respective power consumption amounts. The electric power company PC performs billing processing by the billing server 20.
In the case of the above example, the amount of electric power supplied to the electric vehicle EV is measured by the supply source electric energy meter 30 of the supply source SP. In this case, the billing server 20 charges the supply source SP with an electric charge according to the amount of electric power supplied to the electric vehicle EV.

However, the electric vehicle EV is owned by the supplier UR. Therefore, the electricity charge according to the amount of electric power supplied to the electric vehicle EV should be originally charged to the supply destination UR.
The electric power billing system 1 of the present embodiment provides a mechanism for correctly charging the electric charge even when the owner of the electric vehicle EV and the supplier SP who supplied the electric vehicle EV are not the same person. do.

The power billing system 1 includes a charging cable 10. The charging cable 10 includes a watt-hour meter that measures the amount of power charged in the electric vehicle EV. The electric power billing system 1 charges the electric power charge based on the measurement result of the electric energy charged by the charging cable 10. The charging cable 10 is an example of a power cable.

Here, the billing server 20 grasps the electric power consumption of each customer by acquiring the indicated value of the electric energy meter (integrated electric energy meter) provided in each customer's home or the like. In the case of this example, the billing server 20 identifies each customer based on the customer identification information (customer ID) that identifies each customer and the identification information (instrument ID) that identifies each watt-hour meter, and also identifies each customer. Understand the customer's electricity usage.
In the case of one example of the figure, the customer ID of the supplier SP is “C01” and the instrument ID is “W01”. The customer ID of the supply destination UR is "C02", and the instrument ID is "W03". The customer ID of the charging cable 10 is "C02", and the instrument ID is "W02".
