Title: (EN) ELECTRIC POWER STORAGE APPARATUS
Abstract: front page image
(EN)

An electric power storage apparatus comprises a first electric storage device; and a second electric storage device, the first electric storage device has an inner resistance lower than an inner resistance of the second electric storage device, and has a power density higher than a power density of the second electric storage device, and the second electric storage device has an energy density higher than an energy density of the first electric storage device, the first electric storage device and the second electric storage device are connected in parallel, and a voltage window of the first electric storage device and a voltage window of the second electric storage device at least partially overlap with each other.
