Abstract: PURPOSE:To make it possible to detect the capacity of a battery, by automatically measuring the voltage of the battery at the time of non-loading. CONSTITUTION:The terminal voltage Vb of a battery 1 is varied by the opening and closing of a switch 3. Herein, when the voltage Vb is higher than the both terminal voltages Vc' of a capacitor 42, a diode 41 is brought to a continuity state in a peak value hold circuit 4 to charge the capacitor 42 and, in a reverse case, the voltage Vc' is held in a state higher than the voltage Vb. That is, the voltage Vc' holds the max. value of the voltage Vb. A sample order circuit 5 comprises a falling detection circuit and generates a sampling order pulse signal Vs directly after the voltage Vb is abruptly lowered. In a sample hold circuit 6, a switch 61 is closed during a time when the signal Vs is present and both terminal voltages of a capacitor 62 become equal to the voltage Vc and, when the signal Vs is not present, both terminal voltages of the capacitor 62 are held to a constant value because the switch 61 is opened. The output voltage V0 of an amplifier 63 proportional to this voltage is always applied to a display meter 7 as a value near to the voltage of the battery and the capacity of the battery is indicated.
