Abstract

PURPOSE:To measure the residual capacity of a lead-acid battery automatically, easily, and surely with a simple constitution by using optical signals through optical fibers to read out a working point of a hydrometer. CONSTITUTION:A hydrometer 3 moves up and down depending on the specific gravity of an electrolyte 2 corresponding to the residial capacity of a lead acid battery 1. When the visible light or infrared ray from a light source 7 is directed into an optical fiber 5, and light from an end (a) of the fiber 5 enters into an end (b) of the fiber 6 after being reflected by a mirror 4 if the ends (a), (b) of the fibers provided adjucent each other are in positions facing the mirror 4, and the light attained to a receiver 8. When the hydrometer 3 is in a level at which the ends (a), (b) of the fibers 5, 6 and the mirror 4 is in a same level, the receiver 8 receives the light, thus the level of the hydrometer is detected. Therefore the specific gravity of the electrolyte 2 can be determined in steps by providing a plurality of combinations of 5-8 for a combination of a hydrometer 3 and mirror 4. Thus the residual capacity of a battery can be measured automatically, easily and surely.
