How to test the maximum failure temperature of lithium batteries

The method of a domestic vehicle testing institute to test the failure of car lithium batteries is to install the lithium battery on the heating plate, and then conduct a charge and discharge experiment. Generally, the battery will fail when heated to more than 100 degrees. Some batteries spray gas and liquid outward; some catch fire and burn; some even explode. Therefore, in the test process, quickly and intuitively testing the maximum temperature of the battery is the most important thing. So how can we quickly and intuitively test the maximum temperature of the battery? This has become a big problem for the vehicle testing institute. The current testing method of the institute is to use a thermocouple to test the temperature of the battery, but there is only one sampling point, so the temperature value tested by the thermocouple is always the highest of the battery. Value, high-density sampling is required to predict the maximum failure temperature of the battery, which brings great trouble to the test. So how can we quickly, intuitively and accurately test the maximum failure temperature of lithium batteries? The vehicle testing institute tried to use the FLIRA655sc infrared thermal imaging camera to replace the traditional thermocouple, and carried out the failure test of the lithium battery, and the result obtained unexpected results, allowing the tester to quickly, intuitively and accurately determine the battery temperature At the highest point, beware of the trouble of using the thermocouple test to repeatedly sample to estimate the maximum failure temperature of the lithium battery. So how does the FLIRA655sc thermal imaging camera quickly and accurately test the maximum failure temperature of the lithium battery? This is due to the powerful function of A655sc. A655sc has a built-in uncooled detector and a focal plane array window for 200Hz high-speed imaging. It can be easily integrated with GenICam and GigE vision protocols to read and display temperature values u200bu200bin real time, and actively track and capture the highest temperature in the decomposition area Point, so that the staff can quickly, intuitively and accurately find the highest failure temperature of the lithium battery through the infrared thermal image. Compared with traditional thermocouples, using FLIRA655sc thermal imaging camera to test the failure function of car lithium batteries is undoubtedly a correct choice.
