VOLTAGE EQUALIZING CIRCUIT OF BATTERY PACK

摘要

PROBLEM TO BE SOLVED: To provide a voltage equalizing circuit of a battery pack which can equalize the voltage of the battery pack having various total number of cells without increasing the type of an IC for equalizing a voltage. SOLUTION: A battery block 101 having cells 1-4 of the battery pack 100 is voltage equalized by equalizing IC 7 for four cells. A battery block 102 having cells 3-6 is voltage equalized by equalizing IC 8 for four cells. The battery block 101 and the battery block 102 share adjacent two cells 3 and 4. Thus, the battery pack having various total number of cells can be voltage equalized by the equalizing IC for the four cells having a high speed and good user-friendliness.
