Battery protection method e.g. for notebook computer battery pack, has switch between battery pack and supplied load held in off position in dependence on detected battery cell voltage

摘要

The battery protection method protects the battery cells in a battery pack (1) from excessive charge drainage by monitoring the voltage across each battery cell, for controlling a switch (104) inserted between the battery pack and the supplied electronic device (11), for holding the switch in the off position. Also included are Independent claims for the following: (a) a control circuit for a battery pack; (b) a battery pack
