Abstract :
A measurement method accompanying with processor is proposed in the paper. It significantly improves the voltage monitor accuracy of a plurality of battery cells in battery pack. The errors introduced by resistor mismatch, temperature variation and input common mode voltage variation, are compensated by multiplexer.
