Battery nail penetrating testing machine
Test safety capability of battery.
Nail penetrates the specimen battery and check whether it will fire
|Corresponding test standard|
Using steel nail penetrating the battery, the tester is used to
check safety capability of battery, and the battery is qualified
without fire, and explosion.
The nail penetrating test is processed under temperature of 20℃±5℃.
The specimen battery has thermocouple whose contact spot is located
on the largest surface.
Place the battery on the fuming cupboard, using stainless nail with
diameter of 2-8mm to penetrate the centre position of largest side
of battery at speed of 10mm/s-40mm/s and keep for 5s.
Test result: the battery is qualified without fire and explosion.
