1 How to control temperature and humidity ? The high and low temperature test chamber is a product placed at a specified temperature and humidity to evaluate its ability to withstand high and low temperatures, as well as humidity. Therefore, the high and low temperature damp heat test chamber has the ability to simultaneously heat, …

As one of the essential power components in modern industry, the chiller has a wide range of applications in factories. This article show the principles of the four major components of the chiller refrigeration system. 1 Consist Compressor The function of a refrigeration compressor is to suck in refrigerant vapor from the evaporator, compress it …

In electrical performance testing, high-temperature testing is an essential part, including high-temperature storage, high-temperature cycling, and thermal chamber testing. Although we will not discuss extreme testing conditions such as thermal shock for now, thermal runaway caused by thermal chamber testing is a destructive test. Under normal high temperature conditions, the battery cells stored at high …

With the rapid development of drone technology, the application scenarios of drones are becoming increasingly widespread, and the challenges of diverse flight environments are gradually emerging. The reliability and adaptability of drones are directly related to the safety and efficiency of flight missions, from extremely cold high-altitude to hot desert ground. In order to ensure …

3 Test results   3.1 Measurement and Analysis of Battery Component Dimensions Measure the dimensions of key components and sub components of LFPB using a digital micrometer (for thickness measurement), digital vernier caliper (for width measurement), and tape measure (for length measurement). Except for the 32650 battery which has an additional central pin (for exhaust …

1 Introduction The application of lithium-ion batteries in daily life (alarm clocks, laptops, smartphones, etc.) and electric vehicles is becoming increasingly widespread, and it is a potential solution to reduce air pollution (the rapid transition from oil-based transportation to battery based clean transportation technology), widely commercialized due to its high energy density. However, under adverse …

With the rapid development of electric vehicles, lithium-ion batteries have been widely used, and the safety issues of lithium-ion batteries are the foundation of the development of electric vehicles. Due to the high energy density of lithium-ion batteries and the flammability of their internal electrolytes, lithium-ion batteries frequently experience thermal runaway during use, leading to …
