PROBLEM TO BE SOLVED: To provide a unit battery which is capable of surely supplying power to a load device and can be safely assembled in short time with less work burden.SOLUTION: Electric power of each unit cell 2 and received power received by a power receiving coil L1 are transmitted from a power transmission coil L2 of a non-contact power transmission device 4 to a non-contact power transmission device 4 of a next row which is disposed in proximity to the power transmission coil L2 and has a power receiving coil L1. The transmitted power is received by the power receiving coil L1 to generate reception current I1, and the reception current I1 resonates in a power receiving resonant circuit. A rectifying circuit rectifies the received power taken out from the power receiving resonance circuit, and superimposes the rectified DC power on the unit cell 2. Power transmission current flows in the power transmission coil L1 by this DC power and the discharge of the unit cells 2, and the transmission current resonates in the power transmission resonance circuit with the time change given by the first switching circuit M1.SELECTED DRAWING: Figure 6 |
