BATTERY CHARGER, ADAPTER AND CHARGING SYSTEM

摘要

A battery charger is provided with a contact to which a battery is connected, an identification unit, a primary charging unit, a secondary charging unit, and a control unit. The identification unit is configured in such a manner as to perform identification processing for identifying whether the battery that is connected to the connector is a compatible battery that directly connects to the connector, or an incompatible battery that indirectly connects to the connector, and to output the identification processing result. The primary charging unit is configured in such a manner as to charge the compatible battery under primary charging conditions suited to the compatible battery. The secondary charging unit is configured in such a manner as to charge the incompatible battery under second charging conditions that will not have an adverse effect on the incompatible battery. The control unit is configured in such a manner as to receive the result from the identification unit, activate the primary charging unit if the result indicates the compatible battery, or activate the secondary charging unit if the result indicates the incompatible battery.
