Abstract: Provided is a cell capacity adjusting device for reducing fluctuations in state of charge (SOC) among cells of a battery pack 101, which is formed by connecting a plurality of cells 111-116 in series, during suspension of operation of electrically-powered equipment whose main power source is the battery pack 101. From among the plurality of cells 111-116, one or a plurality of cells having a voltage value equal to or higher than a cell capacity adjustment target voltage are selected. By the selected cells, an intermittent operation unit 105, which operates even during the suspension of operation of the electrically-powered equipment, is caused to perform an intermittent operation. Through repetition of the intermittent operation, voltage values of the selected cells are decreased. Thus, fluctuations in state of charge (SOC) among cells are reduced without unnecessarily discharging battery stored energy of the battery pack 101.

Abstract: A method and a device for determining the actual capacity of a battery uses a set of characteristic curves, wherein at the start of a discharge process the initial voltage of the battery, the magnitude of the discharge current and the temperature of the battery are determined. From this, by comparison with the data provided in the set of characteristic curves, a characteristic curve is selected and an initial state of the battery is determined. At the end of the discharge process, the final voltage of the battery is measured. The final voltage is compared, at the end of the discharge, with the voltage expected based on the selected characteristic curve and, in the event that the final voltage is smaller than the voltage expected based on the discharge process, it is determined that the actual capacity of the battery is smaller than the available capacity assumed at the start of the discharge process.
