At the 2021 Shanghai auto show, we saw the strong rise of many new energy vehicles, which also shows that the trend of electric vehicles will be faster and faster. In the technology of electric vehicles, the charging problem needs to be solved, and the battery life problem also needs to be solved, so that more people can choose electric vehicles, and the automobile battery has become an important breakthrough. For the batteries of new energy vehicles, the carbon fiber battery box is now used. Let's talk about the use of carbon fiber battery box in new energy vehicles. It shows the above advantages.
There are many advantages in using carbon fiber composites in the battery shell of new energy electric vehicles. To sum up, there are several levels.
The battery box made of carbon fiber composite material is very light, stable, safe and reliable. Compared with the traditional battery box, the advantages are more obvious. Traditional battery boxes are usually made of aluminum and steel. The lightweight structure of carbon fiber materials has many advantages in fuel powered vehicles and new energy electric vehicles. It's very light, and it's very good for improving battery life.
Carbon fiber battery box is generally made of carbon fiber composite materials and some aluminum parts. The performance index of the shell is generally determined by the structural design of the bottom cover: Generally speaking, the specific core material is surrounded by multi-layer carbon fiber and epoxy resin. Mixed variants of carbon fiber and glass fiber are also possible. The base can protect the battery from the impact from below and collision with obstacles or other vehicles without fear of strong impact on the battery.
In addition to the advantages of light weight, carbon fiber also has many advantages: the hardness of the battery shell is comparable to that of aluminum structure, but the carbon fiber used is much less, and the thermal conductivity is about 200 times that of aluminum. Carbon fiber composite can scientifically and reasonably protect the battery from the adverse effects of cold and heat. At the same time, the battery box made of carbon fiber composite material is impermeable and airtight, which greatly ensures the safety of the battery box.
Another advantage of carbon fiber battery box is that new energy vehicles need to be replaced in normal use. Many new energy vehicle companies will take this as their selling point. With the replacement of the power station, the battery can be replaced quickly. Many brands of new energy vehicles have installed battery replacement service on domestic highways. The empty battery can be quickly replaced with a fully charged battery, and the whole replacement process takes only three minutes. Lighter weight is also important. Only the lighter weight can be replaced easily and quickly.
Carbon fiber battery box is not only lighter, but also more scientific and reasonable to protect the battery from the adverse effects of cold and heat. This helps to promote effective assurance of the right temperature in the battery.
In general, the advantage of carbon fiber battery box in new energy vehicles is to reduce the weight and improve the endurance and performance of new energy vehicles. The strength is high enough to ensure driving safety. One is that it has very good thermal conductivity to ensure that the temperature of the battery can meet the demand. The other is the light-weight battery pack, which is more convenient to replace.
