Title:
VOLTAGE EQUALIZER AND VOLTAGE EQUALIZATION METHOD
Document Type and Number:
WIPO Patent Application WO/2014/141989
Kind Code:
A1
Abstract:
Cells (Ce1-Ce5) are divided into two groups, and the direction in which electrical charges move between adjacent cells (Ce) is determined such that the electrical charges are moved from a cell (Ce) positioned at the boundary of the group having the higher average voltage to a cell (Ce) positioned at the boundary of the group having the lower average voltage. When the switches (Sw1, Sw2) are turned on and off such that the electrical charges are caused to move from one adjacent cell (Ce) to another adjacent cell (Ce), switches (Sw1, Sw2) are turned on and off until the voltage of one cell (Ce) is brought below the average voltage (Vave) by an offset voltage (Vt). When the switches (Sw1, Sw2) are turned on and off such that the electrical charges are caused to move from the one cell (Ce) to the other cell (Ce), the switches (Sw1, Sw2) are turned on and off until the voltage of the one cell (Ce) is brought above the average voltage (Vave) by an offset voltage (Vt).
