IEC 60335-1 BB-20.1 Prismatic Cell Battery Enclosure Pressure Test Equipment 2.5MPa

The Battery Case Pressure Testing System is a dedicated laboratory test solution developed for evaluating the pressure resistance and mechanical strength of battery enclosures used in battery-operated appliances.

Designed for IEC 60335-1:2020 Appendix BB-20.1, the system applies controlled gas pressure to the battery enclosure and allows the operator to evaluate its ability to withstand the pressure associated with an abnormal battery fault condition.

The equipment is particularly suitable for testing prismatic and monolithic battery cells using metal-ion chemistry, making it useful for battery manufacturers, electrical appliance manufacturers, R&D laboratories, certification bodies and third-party testing laboratories.

Unlike a conventional battery charge/discharge tester, the SN1123B focuses specifically on battery enclosure pressure resistance and structural integrity.

The system adopts a manual booster pump, mechanical pressure indication and selectable gas-volume injection. This provides a straightforward testing configuration for laboratories that need a dedicated IEC 60335-1 BB-20.1 battery case pressure testing apparatus.

The SN1123B is configured for the battery enclosure pressure test specified in IEC 60335-1:2020 Appendix BB-20.1, providing a dedicated solution for appliance and battery safety compliance testing.

The system provides a pressure range of: 0.01 - 2.5 MPa

This gives the equipment sufficient operating capacity for the high-pressure conditions required by the applicable battery enclosure test procedure.

Different test samples may require different gas volumes. The tester supports: 20 mL / 30 mL / 50 mL / 100 mL

The selectable gas-volume configuration provides greater flexibility for laboratory testing and method setup.

The equipment uses a manual pressure booster pump to establish and regulate the required test pressure.

The operator can monitor the pressure while manually increasing the pressure during the test.

This configuration provides a relatively simple mechanical structure and is suitable for laboratories looking for a dedicated, easy-to-operate battery pressure testing solution.

The standard sealing joint uses an orifice with a diameter of: Φ 2.85 ± 0.05 mm

This interface is designed around the test configuration specified for the BB-20.1 procedure.

The purpose of the BB-20.1 test is related to the pressure generated by a metal-ion battery inside the enclosure of a battery-operated appliance under a fault condition.

The test evaluates whether the enclosure can withstand the resulting pressure and whether the battery case maintains adequate structural integrity.

In practical terms, the test is intended to help determine whether the enclosure can resist abnormal internal pressure without unacceptable structural failure.

This makes the test particularly relevant to:

• Battery-operated household appliances
• Prismatic battery cells
• Metal-ion battery systems
• Battery enclosures
• Battery compartments
• Appliance manufacturers
• Battery safety laboratories

The tester uses a manual booster pump to establish the required initial pressure in the test system.

The pressure is monitored through the pressure measurement system while the operator controls the pressure manually.

According to Sinuo's BB-20.1 test configuration, the sample is initially pressurized to approximately 2070 kPa ±10%. The specified gas volume is then introduced through the Φ 2.85 ±0.05 mm orifice, after which the pressure behavior of the enclosure is evaluated according to the applicable test procedure.

The standard-related test sequence should always be performed according to the applicable edition of IEC 60335-1 and the laboratory's approved test procedure.
