How to do the temperature cycle test in the battery thermal shock cycle test chamber for digital equipment mobile power supply?

The battery thermal shock cycle test chamber is used for temperature cycle test. The power supply in the high and low temperature environment, the quality of the power supply directly affects the daily testing work of the laboratory. To judge whether the performance is good or bad, one of the detection tests is the "temperature cycle test". Let's have a brief understanding of this test.

Digital equipment mobile power temperature cycle test:

Test equipment: battery thermal shock cycle test chamber

Equipment Model: Huanyi Instrument HYQT-80

Test standard: GB/T 35590-2017 General specification for mobile power supply for portable digital equipment

The test steps are as follows:

a. After charging is required;

b. Put it in a high temperature box of 75℃±2℃ for 4h;

c. Put it in a low temperature box of -20℃±2℃ for 4h;

d. Repeat steps b) to c) 5 times (transfer time not more than 30 min), and finally put it in a room temperature of 23℃±2℃ for 24 hours.

After the test is over, the final inspection is carried out.

Clause 11.6 of GB 31241-2014 requires that the mobile power supply should have a temperature protection function, so that the internal lithium-ion battery can work within the safe charging and discharging temperature range.

This means that the lithium-ion battery or battery pack used in mobile power products needs to conduct more overall tests of mobile power products in addition to meeting the assessment of the corresponding battery and battery pack independent chapters.

The above is the temperature cycle test of the mobile power supply with the battery thermal shock cycle test chamber. If you want to know the overall test of the mobile power supply, you can visit the official website of "Huanyi Instrument" and consult relevant technical personnel.
