  • Patent number: 7616003
    Abstract: A method for determining the deterioration of an accumulator battery, hooked up with loads in a system, based on the result of measuring internal resistances of an accumulator battery, the method including predetermining a temperature at which the deterioration of the accumulator battery is determined, calculating temperature correction coefficients, predetermining resistance-voltage conversion factors, measuring the internal resistances and temperature of the accumulator battery, converting the measured internal resistance values into the internal resistance values, converting the internal resistance values at the specified temperature into the terminal discharge voltage values and determining whether the accumulator battery is deteriorated or not by means of comparison of the terminal discharge voltage values.

  • Patent number: 7525284
    Abstract: The method for calculating charged rate of a secondary battery is intended to calculate charged rate of a secondary battery which supplies electric power to loads, and comprises the step to measure voltage of the secondary battery more than once in a predetermined period of time after termination of charge or discharge, the step to determine the coefficients of a quadric or more exponential damping function which approximates the time characteristic of the open circuit voltage of the secondary battery by recursive calculation with the plural measured voltage values, and the step to calculate a convergent value of the open circuit voltage of the secondary battery from at least the exponential damping function with the coefficients determined above. Therefore, precise charged rate of the secondary battery can be calculated from the precise convergent value of the open circuit voltage.

  • Patent number: 6838883
    Abstract: In order to monitor a state of a battery, a threshold value of an internal impedance of the battery is first determined. It is prepared an approximate expression indicating a correlation between a residual capacity of the battery and an internal impedance of the battery which is greater than the threshold value. The internal impedance of the battery is then measured. When the measured internal impedance is the threshold value or less, the residual capacity is determined as an initial value. When the measured internal impedance is greater than the threshold value, the residual capacity is monitored with the approximate expression.
