Abstract:
1. An electric power information management apparatus comprising: a power meter that measures electric power data on electric power to be supplied from a storage battery of a vehicle to an electric power facility; a security module that associates and encrypts identification information corresponding to the vehicle and the electric power data measured by the power meter; a communication device that transmits to an electric power management database held by a management center apparatus the identification information corresponding to the vehicle and the electric power data that have been encrypted by the security module to store an electric storage amount based on the electric power data associated with the identification information in the electric power management database and comprising a quantity of the electric power having been supplied from the storage battery of the vehicle to the electric power facility; and an electric power control device capable of inputting the identification information corresponding to the vehicle and a charge amount for charging the storage battery of the vehicle comprising a quantity of the electric power being supplied to the storage battery of the vehicle from the electric power facility, the electric power control device causing the management center apparatus to determine whether or not the input charge amount exceeds the electric storage amount associated with the identification information and stored in the electric power management database upon input of the identification information and the charge amount, and when the management center apparatus determines that the charge amount does not exceed the electric storage amount comprising the quantity of the electric power having been supplied from the storage battery of the vehicle to the electric power facility, the electric power control device causing the management center apparatus to update the electric power management database using a value obtained by subtracting the charge amount from the electric storage amount as a new amount for the electric storage amount and extracting from the electric power facility or a different electric power facility electric power indicated by the charge amount that is used for updating the electric storage amount and then supplying the extracted electric power to the storage battery of the vehicle corresponding to the identification information that is input.
