crush test method description
Cylindrical or prismatic, bag-shaped, button/coin-shaped cells or batteries are crushed between two planes which the diameter greater than 20 mm. Cruh at the first contact point at a speed of about 1.5 cm/s until one of the following three conditions occurs:
The maximum pressure reaches (13±0.78)kN;
The battery sample voltage drop at least 100mV (or 1/3);
At least 50% (or 1/10) of deformation when compared to the initial thickness of the battery;
Once the maximum pressure reached or voltage drop exceeds 100mV (1/3) or the cell core deforms by more than 50%(1/10), the pressure should be relieved.
For prismatic or pouch cell specimens, only the widest surface shall be extruded;
For button or coin cell samples, compress the plane;
Cylindrical cells should be extruded in the vertical direction of the vertical axis.
Each test cell sample should be subjected to only one crush. The test sample should continue to be observed for 6 hours, and no other test was performed before the sample test.

Extrusion fixture type:
1 Set flat circular extrusion plates (20cm in diameter)
Control system function and features:
1. The test software also has automatic voltage collection function, according to the test requirements of the single battery, until the battery case is broken or the battery is short-circuited (the internal voltage of the battery becomes 0V), that is, the voltage change of the battery during the test is automatically collected during the test. When the voltage is zero, the device automatically stops testing;
2. According to the requirements of the power battery test, the test system can be squeezed to 30% of the size of the battery module (ie, the deformation ratio), or set a certain pressure value (such as 200kN for the pressing force), when the extrusion test is reached. After the pressure value, the pressure duration can be set (within 1 to 9999 s) and the test is stopped, that is, the pressure test mode or the test is stopped immediately.
3. It can be implemented or built-in high-precision encoder, which can be freely programmed in the test software to set multi-step, multi-stage extrusion test requirements. In the test in which the stroke control variable is set, after the extrusion test is finished, the pressing plate is kept in the state after the end of the test, and the expansion of the battery is prevented from causing the extrusion head to move back; and at the same time, after the extrusion is completed, The compression plate is returned to the initial position and two options are available.
4. Combine the above various test requirements
A. It can be used to test any single of them, pressure, the stroke nd voltage (the shape variable can be a numerical value or a percentage)
B. It is also can be used to do the test of any combination of the three test(pressure, stroke, voltage), that is, to set three or two test conditions at the same time, and any one of the conditions is met, the testing stoped. Comply with all the latest international test requirements for single or modular batteries
C. The test system can set the speed of the test, and can set the test speed required for the test in the computer software, the unit is: mm/min.
