A battery pack (10) used as the power source of a portable information device (11) is configured to measure the consumption of battery power and transmit data indicating the measured consumption of battery power together with a battery pack ID code and a charging server IP address to the information device (11). The information processing apparatus (11), when connected to the internet, transmits the data on the consumption of battery power and the battery pack ID code given from the battery pack (10) to a charging server (12). The charging server (12) refers to the information given from a contract matter input device (16) and calculates the charge for the consumption of battery power on the basis of the data on the consumption of battery power and the battery pack ID code. The charged for consumption of battery power calculated by the charging server (12) is transmitted together with data including an account number of the account for payment of the charge to an account managing server (13) of a bank, for example, to enable procedures of automatic payment of the charge from the account. |
