IEC62133 Battery Extrusion Puncture Tester – Safeguarding Battery Safety
Test description:
The test should be carried out at an ambient temperature of 20℃±5℃. The servo motor applies pressure, and the fully charged single cell or unit battery is placed in two planes for squeezing. The battery is squeezed or punctured perpendicular to the plate direction with an extrusion force of 13KN±0.78KN (pressure can be customized). Once the pressure is greater than the maximum value, the extrusion test can be stopped. The extrusion test verifies the safety performance of the battery. During the test, the battery does not have an external short circuit. The tested battery is qualified if it does not explode or catch fire.
Safety protection system:
- Equipped with a fuse-free protection switch.
- Test chamber: extreme over-temperature, fan and motor overheat relay protection.
- Power supply: leakage protection, overload and short circuit protection.
- Temperature and humidity zero-crossing thyristor power controller protection.
Technical parameters:
| Control method | PLC+Touch screen control（There are also computer-controlled models that can be customized） |
| Drive mode | Servo Motor+Screw drivedrive |
| Inner box size | 500x450x460mm (width x depth x height) (Can be customized upon request） |
| Equipment dimensions | 800x700x1700mm (width x depth x height) |
| Inner box material | SUS304Stainless steel plate, 1.5mm thick and with Teflon |
| Outer box material | 1.5mm thick cold rolled steel plate with paint treatment |
| Observation window | Size250x250mmTwo layers of tempered glass, transparent window with stainless steel mesh |
| Smoke outlet | 100mm diameter, located at the back of the box |
| Pressure relief port | The opening size is 200x200mm, located at the back of the box. When the sample explodes, the pressure relief port pops open to release the pressure. |
| Door | The single door opens to the left. The door is equipped with a safety limit switch and an explosion-proof chain on the side. The equipment can only be operated after the door is closed to ensure personnel safety. |
| Test hole | There is a 50mm diameter test hole on the left side of the device, which is convenient for inserting temperature, voltage and other collection lines. |
| Collection line | Reserved voltage and temperature acquisition ports |
| Lighting | The machine is equipped with a lighting lamp to facilitate observation of the status of the tested sample. |
| Extrusion needle speed | 0.1~40mm/s adjustable |
| Pressure Range | 1～20kN（There are also 50KN, 100KN, 200KN, 500KN, 800KN to choose from） |
| Pressure display accuracy | 0.1N |
| Sensor resolution | 1/10000 |
| Unit conversion | kg, N, lb |
| Maximum battery size tested | 200x200x200mm (width x height x depth) |
| Extrusion stroke | 250mm |
| Holding time | 0～99H can be set arbitrarily |
| Extrusion head | Standard flat extrusion head, area ≥ 20cm² |
| Extrusion degree | The extrusion pressure reaches 13±0.2kN and is maintained for 1min; |
| Extrusion direction |
a. For cylindrical batteries, the longitudinal axis of the extruded battery should be parallel to the two plates of the extrusion device; b. For square and soft pack batteries, only the wide surface of the battery is subjected to the extrusion test; c. For coin or button type batteries, the compression test is carried out with the upper and lower surfaces of the battery parallel to the flat plate. |
| Acupuncture needle | Φ2mm, φ3mm, φ4mm, φ5mm, φ6mm, φ7mm, φ8mm high temperature resistant steel needles, length 100mm, 2 pcs each. (Can be customized according to customer requirements） |
