Abstract

PURPOSE:To indicate the residual capacity of a battery for a motorcar, an electric motorcar and the like as a value by providing a sensor prepared from an optical fiber and having a crooked part located in the electrolyte of the battery, and detecting the emitted light as an electric signal corresponding to the specific gravity of the electrolyte. CONSTITUTION:The symbol 6 in the figure represents a converting circuit which converts an electric signal obtained from a light receiving part 4 according to the specific gravity of electrolyte into the maximum value when the electric signal is the minimum, namely a battery is fully charged, and converts said signal into a digital amount. The symbol 7 represents a display part which displays the required information in response to the output signal of the circuit 6. When a battery 2 is fully charged, the specific gravity of the electrolyte becomes the maximum, and as the result, the intensity of light supplied from a light source 3 is most highly attenuated at a crooked part 1c of a sensor 1, and the minimal amount of light falls on the light receiving part 4. The light receiving part 4 transmits an electric signal, which corresponds to the amount of light received by the part 4, through a selection switch 5 to the circuit 6. Following that, thus transmitted information appears on the display part 7 in percentage.
