Title:
ELECTRICITY ACCUMULATION SYSTEM
Document Type and Number:
Japanese Patent JP3882703
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To properly distribute charging/discharging power fed to an electricity accumulation system to a battery and a capacitor, and to reduce power loss generated in the whole electricity accumulation system.
SOLUTION: The electricity accumulation system (9) comprises a battery (11), a capacitor (10), and a converter (12) that distributes a charging current to the battery (11) and the capacitor (10) at an arbitrary ratio. A converter control device (13) operates the power loss in the electricity accumulation system (9) induced in charging and discharging, operates the distribution ratio of the charging/discharging current to the battery (11) and the capacitor (10) so that the power loss in the electricity accumulation system (9) becomes minimum, and controls the converter (12) based on the operated distribution ratio.
