Title:
CELL VOLTAGE CORRECTION CIRCUIT
Document Type and Number:
Japanese Patent JP2016034219
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cell voltage correction circuit capable of reducing energy loss and heat generation following correction of dispersion of terminal voltages between a plurality of cells.SOLUTION: Coils 101-104 are arranged correspondingly to individuals of a plurality of cells C1-C4 connected in series. Respective one-ends of the coils 101-104 are respectively connected to one-terminals of the cells C1-C4 through first MOSFETs 211-214. The other ends of the coils 101-104 are respectively connected to the other terminals of the cells C1-C4 through second MOSFETs 221-224. Third MOSFETs 231-234 are respectively interposed between a plus terminal of the cell C4 located on the plus side farthest end and the other ends of the coils 101-104. Fourth MOSFETs 241-244 are respectively interposed between a minus terminal of the cell C1 located on the minus side farthest end and the one-ends of the coils 101-104.SELECTED DRAWING: Figure 2
