Comprehensive Lithium Battery Safety Performance Testing System BE-JKXT-08

Crush, Nail Penetrate

Test Method

Crush

The test battery is placed between two planers and approximate 13KN crush force can be performed through hydraulic arm with an 32 mm diameter piston or bench clamp;

The crush remains till hydraulic pressure reading data up to 17Mpa. Once crush force reached and system will release automatically;

Nail Penetration

Battery specimen is placed and fixed in a planner, nail penetration speed at 10mm ~ 40mm remains to setting time and pull out steel nail automatically to complete test.
