ABSTRACT:
Provided is an electric energy storage device capable of improving a charging efficiency when electric power supplied with an input current having a current value repeatedly exhibiting peaks and valleys is to be storaged by using a secondary battery and an electric double-layer capacitor. The electric energy storage device includes: an electric double-layer capacitor; and a battery unit including at least one secondary battery, the battery unit being connected in parallel to the electric double-layer capacitor, in which: a ratio of an internal resistance of the electric double-layer capacitor to an internal resistance of the battery unit is determined according to parameters relating to the input current.
