Abstract
An electronic device is electrically connected to a secondary battery through a battery terminal, and is electrically connected to a charger through a charge connection section and a communication connection section. The electronic device includes a voltage range detection section, a switch section, a charge control section, and a device-side microcomputer. The charger includes a charger-side charge control section and a charger-side microcomputer. When certification data which is transmitted from the charger is prescribed data, the device-side microcomputer performs determination. When voltage range detection section determines that a charging voltage, which is applied to the charge connection section, is included in a prescribed range, the device-side microcomputer causes the switch section to be ON. The secondary battery is charged through the switch section or the charge control section or through both the sections.
