“Blade battery” is full of goods, how big is BYD’s “ambition”?

Time Back In January 2020, BYD revealed the existence of blade battery first to the public. “The volume is more than 50% higher than the traditional iron battery, which has high safety, long-service life. It can reach a million kilometers or more, and a few words, it will hang your appetite.

Next, in March 2020, the blade battery was officially released, supporting a mileage of over 1.2 million kilometers, and the single charging can satisfy 600 kilometers of battery life, through the harsh needle Piercing test … Then, the blade battery is not noisy.

Now, the blade battery has been exposed for 1 year, and with the understanding of the blade battery, the “attention” of this technology is also Daddy. However, if Nantong said, in fact, the true power of the blade battery is now appearing.

Before the reason, it reiterates the knowledge of the blade battery. The blade battery is essentially a lithium iron phosphate battery. Due to the relationship of the material, it is originally safer than the three yuan lithium battery, only the unique blade structure makes it these two advantages further improve.

The maximum disadvantage of lithium iron phosphate battery is that the energy density is low, and the battery has no ternary lithium battery. The blade battery has greatly improved the spatial utilization and energy density due to structural innovation, so that this short board is overcome to some extent.

1, carrying models – from pure electricity to mix

Back to our problem, why do you say that the real power of the blade battery began? First, from the mounted model, BYD Han EV is the first model with blade battery, and the subsequent BYD Song Plus EV, Tang Ev, Qin Plus EV, etc. also give arrangements.

But everyone finds no, just starting the blade battery is equipped with pure tram type, Han DM, Tang DM, is still three yuan lithium. In response to this, there is industry insiders that it is because the phosphate battery itself exists in the shortcomings of “low temperature performance and weight”, and there is no good solution.

But very quickly, BYD played strength The face, DM-I premium released in the past, there is a “special power blade battery”. Abstract 3.8L / 100km fuel consumption, 1200 kilometers of battery life, etc. have its credits.

The three models carrying the blade battery and the DM-I super mixing technology will be listed in March this year. BYD This trick is actually in show muscles, showing the exhibition of blade batteries to the outside world.

At the same time, BYD has also continued to study the phosphithium iron phosphate battery. At present, the energy density of the blade battery system is 140Wh / kg, and BYD claims that the future can reach 160Wh, and the cost will further decline.

2, battery supply and demand – from self-supplied

Due to the relationship of capacity, the mass production pre-chop battery is limited to itself. With the improvement of capacity, we will also see the figure of the blade battery in other brands soon. BYD has previously said that the models of external support are expected to be listed in the second half of 2021 or in early 2022.

Because of this, it is a red flag that has been comparative fire recently. According to the information of the Ministry of Industry and Information Technology, the red flag brand new pure electric vehicle E-QM5 will be equipped with “Chongqing Fudi Lithium Battery Co., Ltd.The production of lithium iron phosphate batteries, taking into account the unique factories producing the BYD blade battery, many people pose a new car or a blade battery’s external supply object.

Although both parties have not confirmed this method, it can be determined that BYD has a confidence in the external supply of the blade battery, because it has repeatedly said that almost all mainstream cars Brand, all cooperation with BYD, is fighting against the use of blade batteries. And before, there is news that BYD “Blade Battery” has won the design of modern cars, and established a modern project group, which is expected to start overseas next year.

If the blade battery is only used by itself, it is inevitable that some self-selling tastes. But if other brands are also robbed, the meaning is not the same, this shows that even competitors It is also recognized. The current domestic power battery’s leading boss is Ningde era. The main attack is a three-dimensional lithium battery. The lithium phosphate is also produced.

If BYD It can achieve large quantities of external supply for blade batteries, which is much stronger than self-sufficient. After all, the overall size of BYD is not large, and the sales volume of 426,972 vehicles in 2020. Once the external supply, you can seize lithium iron phosphate. The market share of the battery, changing the three yuan lithium battery “a big” situation, and improve BYD’s influence in the entire new energy market, challenge the status of the faucet of Ningde Times.

As far as the “blade battery” technology at this stage, Nang Ge believes that its biggest advantage is safety, this is also a lot of consumers’ voice. However, it is necessary to break through some bottlenecks. It also needs to break through some bottlenecks. The first is the energy density of the battery, 140Wh / kg is already excellent, but the Ningde era has upgraded the 811 battery system energy density to 180Wh. /kg.

The second is the low temperature performance of the battery, and the owner feedback on the Internet, the Han EV winter loss of the blade battery is serious, althoughThis phenomenon is “normal” in the new energy world, but the low temperature performance of lithium iron phosphate batteries is indeed more than three yuan lithium batteries. If BYD can make this short board, it is undoubtedly the brocade.

Terranant thinking, with it said that “blade battery” is a high black technology, it is better to say that it is a technical breakthrough in grounding. The battery’s supply chain system is open, selling this “product” product is sold to other car companies, is the truly powerful moment of BYD “blade battery”. At that time, BYD may really become new energy cars. Absolute leader. What do you think about this? Welcome to “the” car domain has no borders “, share your opinion in the following reviews.
