Abstract

The invention relates to the technical field of battery inspection and detection, in particular to a lithium battery safety performance experiment protection device which comprises a test bed, a first protection cover is arranged outside the test bed, the first protection cover surrounds the test bed, a second protection cover is arranged outside the first protection cover, and the second protection cover surrounds the first protection cover. The first protective cover is fixedly connected with a first air inlet pipe and an air outlet pipe, the first air inlet pipe and the air outlet pipe are both communicated with the interior of the first protective cover, the air outlet pipe is fixedly connected with an air extracting pump, the second protective cover is fixedly connected with a second air inlet pipe, the air outlet pipe is fixedly connected to the second protective cover, and the second air inlet pipe is communicated with the interior and the exterior of the second protective cover. The air outlet pipe is communicated with the outside of the second protective cover, the other end of the first air inlet pipe is communicated with the outside of the second protective cover, and the other end of the second air inlet pipe is communicated with a gas generation device capable of conveying inert gas.

Description

technical field [0001] The invention relates to the technical field of battery inspection and detection, in particular to a lithium battery safety performance experimental protection device. Background technique [0002] Batteries are widely used in electric vehicles, energy storage devices, mobile phones, electrical appliances, industry, and consumer goods. In recent years, with the large-scale use of electric vehicles in society, some problems have also been encountered. For example, a small number of electric vehicles have appeared for various reasons. It can cause the lithium battery to catch fire, which leads to the problem of burning the whole vehicle, or the rupture of the lithium battery causes the leakage of toxic electrolyte into the air. The risk of fire, combustion and explosion of energy storage equipment and lithium-ion power battery is caused by the instantaneous release of chemical energy from the battery at high temperature (high-voltage electric shock is no...
