Patent ID: 7692408

Claim:
A charging device for use in charging plural types of secondary batteries, comprising: a power source unit for supplying a charging current to an object secondary battery; a battery type signal receiving unit for receiving a battery type signal indicative of the type of the object secondary battery; a battery temperature signal receiving unit for receiving a battery temperature signal indicative of a temperature of the object secondary battery; a blowing unit for blowing an air to the object secondary battery; a storage unit storing reference judging temperatures for determination of charging-incongruent temperatures of the plural types of secondary batteries, in a matching relationship with the types of the secondary batteries; and a control unit; wherein the control unit is configured to cause the blowing unit to perform a cooling operation if the temperature of the object secondary battery represented by the battery temperature signal received in the battery temperature signal receiving unit exceeds a reference judging temperature stored in the storage unit in a matching relationship with the type of the object secondary battery that is represented by the battery type signal received in the battery type signal receiving unit, and wherein the control unit is configured to cause the blowing unit to stop the cooling operation if the temperature of the object secondary battery represented by the battery temperature signal received in the battery temperature signal receiving unit is less than or equal to the reference judging temperature.
