Nail penetration test for cell is to test battery pack with specified nail according to corresponding country’s or industrial requirements. The ideal result is that the pierced cell would smoke or burn, while other cells can work normally. The purpose of nail penetration test is to make sure that hard strike on battery or broke of single cell won’t influence the work of whole battery pack or trigger safety accident in their daily use, which is particularly important for battery pack of electro car and motorcycle, etc. The battery packs that can pass nail penetration test are superior to normal pack in material, craft, designing and manufacturing. And the safety of this pack would increase greatly with relatively high cost.
Note: Nail penetration test of Panasonic is the top requirement of this test
