Abstract

A battery state detecting system capable of calculating the remaining capacity of a lead battery accurately. The battery state detecting system comprises a voltage measuring portion for measuring the voltage of a lead battery, a current sensor for measuring the current in the lead battery, and a microcomputer which calculates the remaining capacity of the lead battery by substituting the OCV of the lead battery measured by the voltage measuring portion into a linear expression which is established beforehand to define the relationship between the OCV and the remaining capacity in advance. The microcomputer calculates the SOH of the lead battery at least from either the measured current or voltage and corrects the OCV measured by the voltage measuring portion by the calculated SOH of the lead battery. The relationship between the remaining capacity and the OCV is approximately expressed by a linear expression regardless of the SOH of the lead battery, and therefore deviation from the linear expression due to the SOH can be prevented.
