Battery pack and method of sensing voltage of battery pack

摘要

The present invention relates to a battery pack (100) and a method of sensing a voltage of the battery pack (100). The battery pack (100) has more battery cells (110) than an individual cell voltage sensing unit (120) can sense the voltages of. The additional battery cells (115,215,216) are sensed using a multi- cell voltage sensing unit (130) and digital processing (140,150).
