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.
