可充電電池組的保護(hù)(Rechargeable Battery Pack Protection):Rechargeable battery packs, such as those used to power mobile
phones, digital cameras and other handheld devices, are particularly
sensitive to overcurrent and overtemperature conditions caused by
accidental shorting and abusive or runaway charging. These
conditions can raise the battery temperature and may result in cell
damage, equipment failure or even venting or smoke.
The principal electrical hazards faced by battery packs are the result
of external short circuits during discharge, or an overcharge situation
caused by using a faulty or incorrect charger. Internal pack faults are
less common, but a failure in any of the complex electronics that
support features, such as fuel gauging or charge control, can increase
the risk. Such conditions can result in a significant overtemperature
event either inside or outside the pack.
