Abstract
PURPOSE:To measure the capacity of a storage battery in a floating charging state with high accuracy by correcting the discharging current and charging current of the storage battery to be measured into constant currents and measuring a discharging quantity, etc. CONSTITUTION:One of parallel connection ends of a charging circuit 9 and a discharging circuit 5 and one terminal of the storage battery 4a to be measured are connected by a current detector 1 to the discharging current and charging current of the storage battery 4a by one current detector. Further, the circuit of a coupled storage battery 4 is provided with a current detector 12. Then the detection currents of both current detectors 11 and 12 are applied to a sum detector 13 to calculate the sum of the discharging current of the storage battery 4a by the discharging circuit 5 and the discharging current of the coupled storage battery 4. Then the discharging current of the storage battery 4a is controlled to a constant value with the sum signal and integrated by a current integrator 8 to measure the discharging amount. Consequently, the capacity of the storage battery is measured in the floating discharge state with high accuracy.
