Title:
CHARGING CONTROL METHOD AND DISCHARGING CONTROL METHOD FOR ELECTRICITY STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/014281
Kind Code:
A1
Abstract:
Disclosed are a charging control method and a discharging control method for an electricity storage device, whereby variations in the inter-terminal voltage of capacitors can be suppressed without using a parallel monitor. A capacitor group is used as an electricity storage means in the charging control method. Said capacitor group includes 2n (n being an integer of 2 or more) electric double-layer capacitors with equal capacitance and numbered from 1 to 2n and is formed such that adjacent electric double-layer capacitors can be connected in series or parallel by a switch and the 2nth electric double-layer capacitor and the 1st electric double-layer capacitor can be connected in parallel by a switch. Adjacent capacitors among the 2n capacitors (Ci) that form an electricity storage unit (21) are sequentially switched from series connection to parallel connection, or the 2nth capacitor (C2n) and the 1st capacitor (C1) are switched to a parallel connection, thereby suppressing variations in the inter-terminal voltage of each capacitor.
