摘要： A device and method is provided that can detect overcharge reliably by separating heat generated by internal resistance and heat chemically generated upon overcharging in a secondary battery. Based on the temperature of the secondary battery detected every first predetermined time by a battery temperature detection section, a temperature gradient operation section calculates a temperature gradient indicating a temperature increase per unit time for every second predetermined time that is longer than the first predetermined time. When a temperature gradient determination section determines that the temperature gradient is larger than a predetermined temperature gradient threshold, which is preset according to the charged state of the secondary battery, N times in a row (where N is a natural number), a fully charged state of the secondary battery is detected.

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： An apparatus estimates charge/discharge electricity amount without being affected by current measurement error. Under specific selection conditions, a no-load voltage calculation part uses pairs of data consisting of current data I(n) and voltage data V(n) corresponding to the current data to calculate 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. If specific current conditions exist for a certain amount of time, an open circuit voltage calculation part calculates the terminal voltage of the secondary battery as the open circuit voltage Voc. An estimated charge/discharge electricity amount calculation part 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 or open circuit voltage over a predetermined period of time.
