Title:
POWER CONTROL DEVICE, POWER CONTROL METHOD, AND POWER CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/121273
Kind Code:
A1
Abstract:
[Problem] To provide a power control device capable of equalizing power between storage batteries, when the storage batteries are connected in series between a positive electrode line and a neutral line, and between the neutral line and a negative electrode line, and DC power is supplied using three lines, namely the positive electrode line, the neutral line, and the negative electrode line. [Solution] A power control device is provided with: a comparison unit which acquires, from a first battery provided between a positive electrode line having a positive potential applied thereto, and a neutral line having a ground potential applied thereto, and a second battery provided between the neutral line, and a negative electrode line having a negative potential applied thereto, the charging state of the first battery and the charging state of the second battery, and compares said charging states; and a power control unit which, on the basis of the result of the comparison by the comparison unit, controls power interchange between the first battery and the second battery such that the charging state of the first battery and the charging state of the second battery are equalized.
