摘要： The present invention provides an apparatus that can estimate the charge/discharge electricity amount without being affected by current measurement error. If specific selection conditions are met, a no-load voltage calculation part (105) takes a plurality of pairs of data consisting of current data I(n) and voltage data V(n) corresponding to the current data and calculates a no-load voltage Vsep as the voltage intercept at a current of zero in a straight-line approximation obtained by statistical processing such as regression analysis using a least squares method with respect to the plurality of pairs of data. In addition, if specific current conditions continue to be met for a certain amount of time, an open circuit voltage calculation part (106) calculates the terminal voltage of the secondary battery as the open circuit voltage Voc. An estimated charge/discharge electricity amount calculation part (114) uses a preset change-in-voltage adjustment constant ΔVbc/adjustment coefficient Kb, change-in-electromotive-force constant Keq and polarization voltage generation constant Kpol to calculate the estimated charge/discharge electricity amount ΔQe as a function of the change ΔVb in the no-load voltage or the open circuit voltage over a predetermined period of time.

摘要： A device for appropriately controlling capacitive variations between battery blocks. A voltage measurement section periodically measures a terminal voltage of each battery block by way of respective potential detection lines electrically connected to both terminals of the respective battery blocks. A discharge section effects electric discharge of each battery block by electrically connecting both terminals of a discharge element to both terminals of the respective battery blocks by way of the potential detection line. A discharge control section periodically computes an amount of variations in electromotive force of the battery blocks in accordance with respective terminal voltages measured by the voltage measurement section in parallel with measurement of the respective terminal voltages performed by the voltage measurement section, and commands the discharge section to effect electric discharge of a battery block exhibiting highest electromotive force when the amount of variations exceeds a first reference amount. Further, when the voltage measurement section measures a terminal voltage of the battery block being electrically discharged by the discharge section, the discharge control section commands the discharge section to stop electric discharge of the battery block being electrically discharged before the measurement is performed.
