Abstract

PURPOSE:To detect the capacity with high precision even during operation by detecting discharge current of the battery and terminal voltage, calculating internal resistance of the battery, dead short current, etc. based on the detection, and determining the capacity in accordance with prescribed experimental formulas. CONSTITUTION:The maximum discharge current I1 of the battery at the time of start of a crank shaft and the terminal voltage V1 of the battery at that point of time, as well as the minimum discharge current I2 flowing during the rotation at a prescribed angle of the crank and the terminal voltage V2 at that point of time, are detected by a detecting circuit 10 for dead short current IB, detecting circuits 14 and 18 for currents I1 and I2, a detecting circuit 12 for the terminal voltage VB of the battery at the time of discharge and detecting circuits 16 and 20 for voltages V1 and V2. Then, internal resistance (r) and current IS at the time of short-circuit of the battery is calculated through digital operation based on the formulas I and II by an operation circuit 24, and further multiplication of corelative functions A and B settled in compliance with the kind of the battery irrespective of the temperature and density of the liquid of the battery by the experimental formula III which accords well with actual conditions, as well as addition of a similar function C through the intermediary of an addition circuit 30, etc. is conducted, whereby the capacity of the battery is determined. By this constitution, the capacity of the battery can be detected with high precision even during operation.
