Battery Nail Penetration Test

Test summary/features: Lithium-ion batteries and other secondary batteries are equipped with protective elements and protective circuits for safety. But safety testing is important to verify that these features can ensure safety.
Nail penetration testing is a type of safety testing done to simulate internal short-circuiting. The sample battery is penetrated with a nail to simulate an internal short-circuit and verify that the battery does not catch fire or burst.
Along with nail penetration testing, ESPEC also provides a comprehensive range of testing/certification services for compliance with UNECE Regulation R100. We also provide safety testing, test consulting and certification services for vehicle battery packs/modules and energy storage devices.

Test equipment
Support for large batteries: Test equipment features an elevator stage enabling testing of various battery sizes.
