In the era of BYD and Ningde, the two major domestic battery giants, there was a rare “space conversation” on the Internet.

Recently, Chairman of Ningde Times Zeng Yuqun said to the public: “Battery safety and battery abuse testing are two different things, but some people pass the abuse test as the safety of the battery.”

One stone provokes thousands of waves, and the outside world regards Zeng Yuqun’s response as a response to the previous puncture experiment of related products of BYD. Prior to March, BYD released lithium iron phosphate blade batteries and demonstrated the safety of blade battery puncture experiments.

After Zeng Yuqun ’s above statement, Li Yunfei, deputy general manager of BYD Auto Sales, issued a Weibo call: “I’m not convinced ?! Then let’s get stuck! Acupuncture is the most difficult, comparable to Everest! It ’s all right, and the other peaks must be all over! “

Behind the technical conflict, the two are competing for the market share of power batteries. 2019 data shows that Ningde Times has more than 50% market share in China, and BYD is also in the first echelon of power batteries with 17% market share. Previously, BYD’s power battery research results were mostly used in its own electrified products. With the production of blade batteries, BYD also officially announced its supply to other manufacturers in the industry, which shallowly threatened the market share of the Ningde era.

What effect does the acupuncture experiment have on the safety of the power battery? Why did the BYD and Ningde era shout about acupuncture experiments at this node? What is the deep meaning behind the dispute between the two? To this end, the automobile prophet connected a number of new energy experts to interpret the secret behind the acupuncture experiment.

The battle between the two giant power battery acupuncture experiments

This online dialogue between the two parties dates back to March this year.

On March 29, 2020, BYD officially released the blade battery. At the press conference, BYD demonstrated an experimental video that shocked friends and businessmen: In the puncture experiment of ternary lithium batteries, lithium iron phosphate batteries and BYD blade batteries, the ternary lithium batteries burned violently and the surface temperature exceeded At 500 ℃, the eggs on the surface of the battery were blown up; BYD blade batteries had no open flame, no smoke, and the surface temperature was 30-60 ℃, and the eggs did not change.
