  • Patent number: 9413041
    Abstract: In a method for adjusting a nickel-metal hydride storage battery, based on a correlation between a charge amount after valve opening and an increased amount of a discharge reserve capacity which are previously ascertained, the charge amount after valve opening corresponding to a target value of the set increased amount of the discharge reserve capacity is calculated and this calculated value is set as a target charge amount after valve opening. In a discharge reserve adjusting step, when a charge amount of the battery from the time when a safety valve device is opened after start of overcharge of the battery reaches the set target charge amount after valve opening, overcharge of the battery is terminated.

  • Publication number: 20160061907
    Abstract: A battery state determination device, which determines a micro-short-circuiting tendency state, includes an impedance meter that applies an AC voltage or an AC current of a measurement frequency to a rechargeable battery, which is subject to determination, and measures complex impedance. The device further includes a detector that detects an absolute value of an imaginary axis component of the complex impedance. The device further includes a determiner that compares the absolute value of the imaginary axis component detected by the detector with a lower limit threshold value. The lower limit threshold value is set based on a measurement result of the absolute value of the imaginary axis component of the rechargeable battery in the micro-short-circuiting tendency state. When the absolute value of the imaginary axis component is smaller than the lower limit threshold value, the determiner determines that the rechargeable battery is in the micro-short-circuiting tendency state.
