摘要： Method for determining a determination voltage (end of discharge voltage) of a secondary battery having a nickel-hydroxide positive electrode based on the state of charge of the battery. The end of discharge voltage is determined in consideration of the voltages when the state of charge reaches a permissible lower limit after first and subsequent discharges of the battery. The voltage at which the state of charge reaches the lower limit for discharges after the first discharge gradually decreases due to a memory effect. As a result, the end of discharge voltage is lower than the voltage at which the state of charge reaches the lower limit after the first discharge.

摘要： If a particular selection condition is satisfied, a non-load voltage calculation unit (105) calculates a no-load voltage Vsep as a voltage piece when the current in approximate straight line obtained by statistical processing using the method of least squares for a plurality of sets of data containing current data I(n) and voltage data V(n) is zero. If a particular current condition or voltage condition is continuously satisfied for a predetermined time, an open-circuit voltage calculation unit (106) calculates a secondary cell terminal voltage as an open-circuit voltage Voc and a voltage-at-zero-current storing unit (108) stores voltage-at-zero-current Vzo calculated by a voltage-at-zero-current calculation unit (107). By using a predetermined voltage change amount adjustment constant ΔVbc/adjustment coefficient Kb, an electromotive force change constant Keq, and a polarization voltage generation constant Kpol, an estimated charge/discharge electric amount calculation unit (118A) calculates an estimated charge/discharge electricity amount ΔQe as a function of the change amount ΔVzo of a voltage-at-zero-current Vzo. It is possible to estimate charge/discharge electricity amount without being affected by the current measurement error.

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.
