<p>PROBLEM TO BE SOLVED: To provide a charger capable of suppressing the reduction of a battery life.SOLUTION: A microcomputer 113 restricts, when charging an auxiliary battery B10, a charge time on the basis of the charge state of the auxiliary battery B10. This enables suppressing the occurrence of an overcharge state of the auxiliary battery B10. Also, the microcomputer 113 restricts a charge current flowing through the auxiliary battery B10 when it becomes possible to make an excessive charge current flow into the auxiliary battery B10. This enables suppressing the occurrence of a state of an excessive charge current flow by mistake into the auxiliary battery B10. Further, the microcomputer 113 enables power supply from other than a solar panel 10 when the auxiliary battery B10 falls into an extremely low charge state. This enables prompt restoration of the auxiliary battery B10 to a normal charge state, while suppressing the occurrence of a state of power supply to a load etc. in the extremely low charge state. Thus, a reduced life of the battery B10 can be suppressed.</p> |
