At present, the trend of electrification in the global automobile industry is irreversible. Battery safety is not only an important factor that consumers consider when purchasing electric vehicles, but also the cornerstone of the healthy and sustainable development of the new energy automobile industry. The reporter learned on the 15th that China’s own brand GAC Ion recently released a new generation of power battery safety technology-magazine battery system safety technology. This has made it the first time for the Chinese automobile industry to realize that the entire package of ternary lithium batteries will not cause fire after acupuncture, which has overcome the recognition. Industry problems. According to reports, lithium iron phosphate batteries and ternary lithium batteries are currently the two mainstream battery technology routes in the global electric vehicle industry. Lithium iron phosphate batteries are widely used in low-to-medium endurance vehicles because of their longer lifespan and lower cost; while ternary lithium batteries are mainly used in mid-to-high endurance vehicles because of their high energy density and low vehicle power consumption. According to the actual use of the current market, the two technical routes of lithium iron phosphate battery and ternary lithium battery will continue to develop in parallel for a long time in the future. The safety of lithium iron phosphate batteries has been relatively recognized by everyone, but the safety of ternary lithium batteries is still a pain point and difficulty recognized by the industry. Relevant departments of the new energy automobile industry chain are all engaged in the research of battery safety technology, and the 'non-fire' battery technology is the most important and most difficult fortress for battery safety. Experts from the China Automotive Technology Research Center and the drafting of the National Battery Safety Standards conducted a rigorous acupuncture thermal diffusion test on the ternary lithium battery pack equipped with the safety technology of the magazine battery system. According to the industry, the release of a new generation of power battery safety technology is a milestone, especially a historic breakthrough in the safety of ternary lithium batteries, which is also of great significance to the development of the global new energy automobile industry.
