Application scope:
Vertical battery cell extrusion puncture tester is mainly suitable for safety performance testing of power batteries, battery packs and other products. The equipment can simulate different conditions that may occur when the battery is squeezed by external force or punctured by sharp objects, so as to evaluate the safety performance of the battery.

Working principle:
Put the battery between two extrusion and puncture plates, apply pressure to the extruded and punctured battery, return to its original position after reaching a certain pressure, or press the battery to a certain deformation according to requirements, maintain pressure for a period of time, and then further squeeze and puncture.

Test standards:
GB/T31485-2015 “Safety requirements and test methods for power batteries for electric vehicles”;
GB/T38031-2020 “Safety requirements for power batteries for electric vehicles”;
GB/T36276-2018 “Lithium-ion batteries for power energy storage”.
