Abstract

PURPOSE: To make the system suitable for cameras, by the automatic selection of a plurality of secondary cells in series or parallelly, depending on the changes in the amount of surrounding light, in the system normally charging the secondary cells with the light electromotive force current of the solar cell groups.
CONSTITUTION: The main circuit consists of the solar cell group 20 in series connection of 16 sets and the secondary cell groups 23, 23' in series connection of two sets respectively, and the Zener diode ZD for overcharge prevention is connected to the solar cell group 20. Further, the output of the cell group 20 is fed to the secondary cells 23, 23' via the overcharge current control, and among them, the switch SW1 changing over the contacts to a and b, and the switch SW2 interlocked with it are inserted. With this constitution, in case of lower illumination intensity, the SW1 is connected to the contact a, to parallelly connect the cell groups 23 and 23', and in case of higher illumination intensity, those are in series connection. In this case, the change over is made by using the output signal of the photo detection element separately provided, depending on the amount of surrounding light.
