Abstract

PURPOSE:To enhance the detection accuracy of the residual capacity of a battery by performing corrections on changes in both the liquid level and the temperature of battery liquid, and electrically detecting the specific gravity, the liquid level decrease and the temperature of the battery liquid. CONSTITUTION:The residual capacity of a battery is displayed through the detection of the specific gravity of battery liquid. The former detection is carried out by changing the up-and-down movement of a metal piece or the like, which is installed in a specific-gravity detection float, electrically into a float displacement signal by means of a float displacement detecting circuit 7 consisting of a search coil 1e and the like. The liquid level of the battery liquid is taken out as a liquid-level displacement signal by means of the float, a search coil 5e and a liquid-level detecting circuit 8. The temperature of the battery liquid is electrically taken out by means of a liquid-temperature detecting circuit 10 consisting of a thermistor 6b and the like. The float displacement signal obtained through the detection of the specific gravity undergoes a correction 9 carried out according to the liquid-level displacement signal, and is subjected to a temperature correction 11 carried out according to a siganl sent from the circuit 10. Therfore, the residual capacity given on the basis of the accurate detection of the specific gravity of the battery liquid is displayed on a meter 12 or the like.
