NOVELTY - A storage battery includes a thermoelectric transducer (3) that performs two different tasks i.e., dissipating and absorbing heat using its first face (1) and second face (2). A thermoelectric module (7) is used in the thermoelectric transducer, and employs a Peltier element. This Peltier element is arranged between the heat transferring and heat insulating plates (5,6) made of ceramic. The plates form the first and second face of the thermoelectric module.    USE - The battery and thermoelectric transducer can be used in various vehicles that are driven by a motor, and other mobile objects such as airplanes, submarines, and spaceships. The temperature regulator is applicable to storage batteries mounted to objects other than cars and vehicles.    ADVANTAGE - The temperature regulator cools down battery more efficiently and sufficiently than a conventional air-cooling method. A ratio of battery driving vs. gasoline-driving increases, and the battery-driving can be used for longer hours, while the service life of the battery is prolonged. The temperature regulator can prevent battery from degrading performance in a low temperature environment of a cold area, and prolong the battery-driving hours.    DETAILED DESCRIPTION - The first face of the transducer is thermally coupled to storage batteries (8A, 8B), and the second face is thermally coupled to thermal-action accelerating medium (4). The first and second face dissipates and absorbs heat respectively responsive to a polarity in exciting battery (8B), so that the batteries and the thermal-action accelerating medium are warmed up or cooled down forcibly.    An INDEPENDENT CLAIM is made for a vehicle.    DESCRIPTION OF DRAWING(S) - The drawing is a sectional view of a thermoelectric transducer of a temperature regulator coupled to a storage battery.
