Problems solved by technology
If you want to obtain accurate test data, you need to place the aging process test cabinet in a designated single environment, but the metering device used to measure the pressure drop change during the aging process works in a single environment, and the measurement data is extremely inaccurate Therefore, the existing technology can only carry out the aging process in a single environment to ensure the normal operation of the metering device
And it is not suitable for the complex environment during high-altitude flight
[0006] Therefore, when the existing test battery aging process is tested, it cannot be applied to the low-voltage environment of aerospace, and its flight environment is a typical environment of lithium variable voltage, variable temperature, low pressure and different humidity

Description
technical field [0001] The invention relates to the technical field of lithium battery aging testing, in particular to a lithium battery aging testing system capable of simulating high-altitude temperature, humidity and pressure. Background technique [0002] With the continuous depletion of underground energy and the increasingly serious damage to the environment by the products of thermal reactions of existing energy sources, it is extremely urgent for human beings to develop a green, environmentally friendly and high-energy new energy source. Because lithium-ion batteries have the characteristics of long cycle life, high voltage, low memory effect, and high specific energy, they were commercialized once they were developed, and are now widely used in mobile artificial intelligence devices, hybrid and all-electric vehicles, and It has gradually penetrated into the aerospace field, such as: electric aircraft (Ruixiang RXIE) and civil aviation aircraft (such as Airbus A350 a...
