<p>PROBLEM TO BE SOLVED: To provide a charger of simple structure provided with sure functionality. SOLUTION: The charger involvers a secondary battery B101 and a charging stand H101. The secondary battery B101 and the charging stand H101 have electrical contacts P102, P106, P101, and P105 through which electrical energy is transmitted. When the secondary battery B101 and the charging stand H101 are coupled to each other, the secondary battery B101 and the charging stand H101 press a spring SP101 or a thermomotively releasing preloading mechanical force device by a coupling force. At this time, the opposite electrical contacts P102, P106, P101, and P105 are brought into conduction, and charging is started. When the secondary battery B101 charging is saturated, the preloading mechanical force is released by produced thermal motion, and the electrical contact P102 or P106 of the secondary battery B101 and the electrical contact P101 or P105 of the charging stand H101 are pushed away from each other, and as a result, charging current to the secondary battery B101 is interrupted.</p> |
