<p>PROBLEM TO BE SOLVED: To provide an uninterruptive power supply device which is enabled to be incorporated integrally into electronic equipment to achieve simplification and compactification of the configuration, or to provide the uninterruptive power supply unit of simple configuration in which especially operational reliability of a secondary battery is secured sufficiently. SOLUTION: The uninterruptive power supply device comprising the secondary battery which accumulates power converted to DC by a power supply part and supplies the accumulated power to the electronic equipment body in case of AC power outage, a cooling fan for cooling the secondary battery, and a fan control part which controls operation of the cooling fan is structures as a package. The undesired temperature rise of the secondary battery is prevented by cooling the secondary battery with the cooling fan, stabilization of a battery characteristic of the secondary battery is achieved, and the operational reliability as the uninterruptive power supply device is secured.</p> |
