Document Type and Number:
WIPO Patent Application WO/2018/139135
Kind Code:
A1
Abstract:
The present invention addresses the problem of lengthening the product life of a power storage device provided with an electric double-layer capacitor. A power storage device 1 is provided with an electric double-layer capacitor 11 and a control unit 12. The control unit 12 controls the charging voltage supplied to the electric double-layer capacitor 11. The control unit 12 changes the charging voltage according to the degree of degradation of the electric double-layer capacitor 11.
