DESCRIPTION
The battery extrusion needle punching test machine meets the requirementsGB8897.4-2002TheGB/T18287-2000TheIEC60086-4: 2000TheIEC62133: 2002TheUL1642: 2006TheSN/T1413-2004TheSN/T1414.3-2004TheGB 31241-2022Requirements for squeeze needle test in the standard
FEATURES
After fully charging the battery according to the prescribed test method, place the battery in two planes and apply pressure perpendicular to the direction of the electrode plates. Apply pressure between the two plates13.0kN±0.78kNThe squeezing force and the speed of squeezing the battery are0.1mm/s.Once the pressure reaches its maximum value or the battery voltage drops by one-third, the compression test can be stopped. During the experiment, the battery should be protected from external short circuits.
