Why is this battery so hot? Let's analyze it together.
Event background: Thanks to the wind drag coefficient data released by BYD Korea, many people are now paying attention to the progress of new cars. Not only car buyers are looking forward to the road experience of new cars, but even many professionals in the industry are paying attention to the specific performance of new cars. BYD Han announced the vehicle information several years ago. This is a medium-sized flagship car advertised by the brand. According to different models, it is divided into Han EV and Han DM. The whole vehicle is developed based on BYD BNA architecture +E platform. There are still many bright spots in the published information. For example, the value of the new car is very avant-garde and the speed is also very avant-garde. It is said that the acceleration time of 100 kilometers only takes 3.9 seconds, while the drag coefficient is only 0.233Cd. Why is it so fast? This involves the "blade battery" on BYD Han.
Aspect 1: This so-called blade battery is actually a brand-new battery developed by BYD.
The battery cells are more than 0.6m long and will be arranged together in a matrix, which looks like a blade inserted into the battery pack. It is said that this kind of battery has great advantages. On the one hand, it can improve the space utilization rate of power battery pack and increase the overall energy density. On the other hand, it can ensure that the battery cell has enough heat dissipation area to transfer the heat generated inside to the outside.
Compared with the traditional lithium-iron battery, the energy density of such a set of "blade battery" has increased by 50%, which also means that the overall endurance of the new car can reach 600km. For many electric vehicle companies, the endurance improvement of electric vehicles is a very important selling point. In addition, the blade battery has the characteristics of long life, and the life of the whole vehicle can reach more than one million kilometers.
Aspect 2: There are different voices in the market for this blade battery.
They think that the blade battery promoted by BYD is just a marketing tool, not a new battery, and more than 300 core patents of this blade are BYD's propaganda caliber, which is a bit exaggerated. First of all, they believe that core patents are the foundation of enterprise development. Whether BYD uses lithium-ion batteries or ternary lithium batteries, the core patents are in Europe and America. According to the search on the patent website, we can see that this battery has applied for hundreds of patents, but it is a bit exaggerated to say that it is a core patent.
Taste the car:
Generally speaking, BYD Korea's blade battery has attracted many people's attention. Although many people in the industry think that BYD is only using a new name to promote the new car, it is undeniable that the popularity of this car is getting higher and higher. As for the battery life and quality, the new car will be clear at a glance after it goes on the market.
