Battery Puncture And Extrusion Tester
Product Decription:
The testing procedure should be executed at an ambient temperature
within the range of 20 ℃ ± 5 ℃. A fully - charged battery is to be
placed between two flat plates. An extrusion pressure of 13KN ±
0.78KN is applied perpendicular to the plates, either for extrusion
or pinprick tests on the battery. Once the maximum pressure value
is reached, the extrusion test can be halted. The test is
considered qualified if the battery does not experience an external
short - circuit during the test, and the battery under test does
not explode or catch fire.
Specific Guidelines for Different Battery Types
- Cylindrical Cells: During the extrusion process of cylindrical cells, the
longitudinal axis of the cell being extruded must be parallel to
the two flat plates of the extrusion device. This ensures that the
pressure is evenly distributed along the length of the cell,
accurately simulating real - world stress scenarios.
- Square and Soft - pack Cells: For square and soft - pack cells, only the wide side of the cell
is subjected to the extrusion test. This is because the wide side
is often the area most vulnerable to external pressure in practical
applications, and testing this side can effectively evaluate the
cell's resistance to such forces.
- Coin - type or Button - type Batteries: In the case of coin - type or button - type batteries, the
extrusion test is conducted using two parallel plates placed above
and below the battery. This setup enables a uniform application of
pressure across the entire surface of the battery, providing a
comprehensive assessment of its structural integrity under
pressure.

FAQ:
1.What specific safety standards does the Battery Overcharge
Explosion-Proof Test Machine comply with, and how does it ensure
the containment of explosions during testing?
Understanding the compliance with international standards (e.g.,
IEC 62133, UN 38.3, GB 31241-2014) is crucial for ensuring that the
machine meets regulatory requirements. Additionally, knowing how
the machine contains explosions will help assess its safety
features.
2. Can you provide details on the explosion-proof design, particularly
the materials used and the construction of the chamber?The robustness of the explosion-proof design is essential for
operator safety. Understanding the materials (e.g., stainless
steel, Teflon lining) and construction details (e.g., thickness,
pressure relief mechanisms) will help evaluate the durability and
reliability of the machine.
3.What customization options are available for the test chamber, such
as size, internal dimensions, and the number of test compartments?Customization options are important for adapting the machine to
specific testing needs. Knowing the range of available sizes and
configurations will help determine if the machine can meet my
unique requirements.
4. Can the machine be integrated with external charge-discharge
testers, and what are the connectivity options available?Integration with external equipment is important for comprehensive
testing. Understanding the connectivity options (e.g., DC test
cable lead-in holes) will help ensure seamless operation.
