Electric object, which connects unintentionally, to be caused, and is usually occurred during battery assembles or repairs, and internal short-circuit is often as manufacture and misses
Caused by difference or abuse are handled.It, can when piercing through battery case by the conductive body of such as needle or nail etc when internal short-circuit
Multiple short circuits can be generated between electrode layers, other than generating internal short-circuit, pierce through the exhaust group that battery case bypasses battery
Part, so as to which hot gas and the uncontrollable perforation by shell of flame be made to leave shell, so as to cause fire or explosion.Thus
As it can be seen that when battery encounters needle or nail when conduction pierces through, the seriousness that short circuit occurs wants serious more more than external short circuit.
And existing battery pack or battery case are made of substantially one layer of battery case, it is also basic without being directed to when battery or battery
Group is occurred short circuit when conductive bodies pierce through by needle or nail and corresponding device is set to go to prevent or take precautions against, and further reduces short
The seriousness of road harm.
Utility model content
