In the reliability verification system of 5G communication equipment, battery safety is one of the key aspects ensuring the continuous and stable operation of the equipment. As a critical component, the thermal stability of the battery under extreme temperature environments is related to the overall safety of the system. Sanwood Technology's Rapid Temp Change Test Chamber strictly adheres to the IEC 62133 standard, which is a fundamental safety threshold for lithium batteries entering the international market. Certification according to this standard effectively proves the safety and reliability of the product, providing compliance assurance for exports (such as to the EU and Southeast Asia).
Equipment Technology
Sanwood Technology's Rapid Temp Change Test Chamber employs a refrigeration system combining high-temperature and low-temperature cooling cycles. With its wide temperature range and rapid temperature change capability, it can realistically reproduce the rapid temperature shocks faced in scenarios such as outdoor base stations and vehicle-mounted equipment, providing sufficient conditions for battery safety verification.
Equipment Parameters
Sanwood Technology's Rapid Temp Change Test Chamber can be customized according to customer parameter requirements. The following are the basic technical parameters that meet the testing requirements of standards such as IEC62133:
Temperature control range: -70℃～+180℃
Temperature fluctuation: ±0.5℃
Cooling rate: +155.0℃～-55.0℃(Linear or non-linear: 5.0℃, 10.0℃, 15.0℃, 20.0℃/min)
Heating rate: -55.0℃～+155.0℃ (Linear or nonlinear: 5.0℃, 10.0℃, 15.0℃, 20.0℃/min)
Temperature Uniformity: 1.5℃ (-40.0℃～+100.0℃)
2.0℃ (+100.1℃～+180.0℃ or -40.0℃～-70.0℃)
Equipment Function
True safety testing lies not only in environmental simulation but also in accurately identifying the impact of extreme stress on the battery. This test chamber can monitor the battery surface temperature, voltage, and structural changes in real time during testing. Combined with its excellent temperature uniformity, it ensures that all parts of the test sample are heated consistently, resulting in reliable test data. This helps engineers accurately define safety thresholds and optimize battery thermal management design and material selection.
From safety design to mass production verification, reliable technical support is indispensable for battery thermal safety testing. Sanwood Technology's Rapid Temp Change Test Chambers, based on precise temperature control capabilities and standardized testing methods, provide 5G equipment manufacturers with testing support compliant with IEC 62133 requirements. This assists customers in systematically evaluating battery safety performance during product development and provides a reliable testing basis for the stable operation of 5G equipment. In addition to the Rapid Temp Change Test Chamber, Sanwood Technology also offers Thermal Shock Test Chamber, Heat-cold Temp & Altitude Test Chamber, and Walk-in ESS Test Chamber, supporting customized services.
