Abstract
A cell voltage detection circuit,comprises a first input selecting means,connected to the positive and negative electrodes of each of cells connected in series to each other to acquire a voltage from either a selected positive or negative electrode of an intended cell, a second input selecting means,connected to the positive and negative electrodes of each of the cells to acquire a voltage from either a selected positive or negative electrode of an intended cell, a voltage detector,to acquire a detected cell output voltage from output voltages of the first and second input selecting means,and,respectively, and a processing means,for converting a detected cell output voltage of the voltage detector,from analog to digital for calculation to provide the voltage of each cell.
