An apparatus for improving protection of a battery pack when the battery pack
is in a very low power state, the battery pack including a plurality of battery
cells coupled to present an output voltage at a battery potential locus and a protection
device for providing a plurality of safeguards to protect the battery pack, affects
operation of the protection device to control at least one safeguard and includes
a current sensing unit coupled with the plurality of battery cells and with the
protection device. The current sensing unit senses a battery traversing current
associated with at least one battery cell. The current sensing unit generates an
alerting signal when the battery traversing current exceeds a predetermined value.
The protection device enables the at least one safeguard in response to the alerting signal.
