<P>PROBLEM TO BE SOLVED: To prevent overload by accurately and simply estimating the deterioration of a storage battery, even in usage method where the switching of charge and discharge per unit time for accumulating means is few. <P>SOLUTION: This control apparatus executes a deterioration measurement method for computing its resistance, by applying a specified current at standby of an apparatus and converts the degree of deterioration and reflecting a temperature measuring method; and when the degree is at a threshold or higher with respect to a reference value, the controller changes the control parameter and prevents overloading of the output. Moreover, in the deterioration measurement, a plurality of data are measured or a plurality of measurement methods are executed; and when there is a change larger than its threshold between it, before running and the same during running, the control apparatus changes the control parameter again. <P>COPYRIGHT: (C)2010,JPO&INPIT |
