With the continuous warming of the global climate, the impact of high temperature environment on batteries has become increasingly prominent.In high temperature environment, problems such as internal pressure rise, electrolyte evaporation, expansion of positive and negative active materials may occur, and even safety accidents such as thermal runaway and explosion may occur. Therefore, it is of great significance to test the high temperature performance of batteries to ensure their safety and stability. The Battery Explosion-Proof High and Low Temperature Chamber of sanwood is a professional equipment to meet the requirements of IEC60068-2-2: 2007 high temperature test method BA, which is used to test and evaluate the impact of batteries in long-term high temperature environment.
