Kind Code:
A
Abstract:
To suppress a load on a secondary battery which is a main power source.SOLUTION: A power source device 10 switches a charge target of a solar battery 20 which is a power generating apparatus, between a capacitor 15 and a secondary battery 17. The power source device includes a charge/discharge CPU 19 serving as a control unit that operates upon receiving power supply from the secondary battery 17. The control unit causes an LED 50 which is an electric apparatus, to operate with power supply from the capacitor 15. When the voltage of the capacitor 15 is lower than a threshold, the control unit charges the capacitor 15 by using the secondary battery 17.SELECTED DRAWING: Figure 1
