<p>PROBLEM TO BE SOLVED: To provide a battery fee charging system that can properly maintain the fee of a battery used as a power supply of an information device. SOLUTION: A battery pack 10 used for the power supply of the mobile information device measures the consumed amount of the battery and transmits battery consumed amount data denoting the measured battery consumed amount to an information device 11 together with a battery pack ID code and a charging server IP address. When connected to the Internet, the information device 11 transmits the battery consumed amount data and the battery pack ID code received from the battery pack 10 to a charging server 12. The charging server 12 references information sent from a contract contents entry device 16 to calculate a battery fee on the basis of the battery consumed amount data and the battery pack ID code. By transmitting the battery fee calculated by the charging server 12 to an account management server 13 of a bank or the like with data of an account number of a charging account, automatic payment processing of the battery fee from the charging account can be performed.</p> |
