According to a power lithium ion battery thermal runaway flue gas safety evaluation testing method provided by the invention, comprehensive analysis, research and judgment are carried out at the aspects of the gas production rate of a lithium ion battery, the personnel safety evacuation time, the ventilation efficiency of a test site, the component analysis of the flue gas generated by thermal runaway of the lithium ion battery and the like, especially in combination with the ventilation efficiency of the test site, the final evaluation result is more real and is close to the actual use condition; and whether the power lithium ion battery is damaged if thermal runaway occurs in the actual use process is really evaluated, so that possible accidents are avoided.
Description
technical field [0001] The invention relates to the technical field of safety testing of lithium-ion batteries, in particular to a safety evaluation test method for thermal runaway smoke of power lithium-ion batteries. Background technique [0002] With the rapid development of energy storage technology, lithium-ion batteries have been more and more widely used in the field of power and energy storage. Due to the advantages of high working voltage, high energy density, long service life, no memory effect and no pollution, power lithium-ion batteries are more and more used in the field of on-board energy storage for new energy vehicles and special vehicles. In the context of the large-scale application of lithium-ion batteries, the safety of lithium-ion batteries, especially the safety of power lithium-ion batteries with high energy density, has attracted more and more attention. [0003] In terms of lithium-ion battery safety, the thermal runaway of lithium-ion batteries is...
