That is, as shown in the charging characteristic diagram of FIG. 6, the terminal voltage of the storage battery changes depending on the amount of charged electricity, so a power supply is sufficient. Note that this voltage value (El varies depending on the charging current f11 and temperature fTl, so the current charging current fIl and temperature (computer calculates and corrects the corrected voltage value fE based on the data of Tl) and the storage battery voltage (■ It is a comparison.
