Charging apparatus for capacitor storage type power source and discharging apparatus for capacitor storage type power source

摘要

A charging apparatus (106) for electrically charging a capacitor storage type power source (107) adapted to store electric energy in electric double layer capacitors comprises a switching circuit for turning on/off the charge current supplied from a charge power source to the capacitor storage type power source, the capacitor storage type power source having a plurality of electric double layer capacitors connected in series and parallel monitors for bypassing the respective charge currents of the capacitors, a constant current control circuit selecting a smaller reference value from a plurality of reference values provided as the current reference value according to the bypassing operations of the parallel monitors.
