A method of testing the failure of lithium-ion battery in China in China is to mount lithium-ion batteries on the heating plate and then perform charging and discharge experiment. Generally, when the battery is heated to 100, it will be invalid, and some batteries are sprayed outwardly; some are burning; some will even explode. Therefore, during the test process, fast and intuitive test battery maximum temperature is the weight.

So how do you get fast and intuitive test battery's highest temperature? This has become a major problem for the vehicle test research institute. This research institute is the test of the thermocouple testing the temperature of the battery, but the sample point is as long as one, so the temperature value tested by the thermocouple is the highest battery. Value, demand high-density-repeated three sampling, in order to estimate the highest failure temperature of the battery, it has brought a lot to test.

So how do you get fast, intuitive and accurate testing of the maximum failure temperature of lithium-ion batteries? The Vehicle Test Institute tried to use the FLIRA655SC infrared thermal imagery to replace the traditional thermocouple, the failure test of lithium-ion batteries, and the results have been unexpected, so that the test personnel can quickly, intuitively and accurately determine the battery. The highest temperature of the temperature, the use of thermocouple testing and then three samples to estimate the highest failure temperature of lithium ion batteries. So how is the FLIRA655SC infrared camera how fast, accurate test of the highest failure temperature of the lithium ion battery? This is to be attributed to the powerful function of A655SC.

A655SC built-in non-refrigeration detector, has a focal plane array window for high-speed imaging functions for 200 Hz, easy to integrate, real-time read and display temperature values, and actively track and capture the highest temperature in the decomposition area. Point, the staff can quickly find the highest failure temperature of the lithium-ion battery through infrared thermal image map. Compared to traditional thermocouples, the failure function of car lithium-ion batteries in the car, which is undoubtedly a correct choice.
