Electric vehicles are gradually accepted, and the market share is growing slowly, which also drives the development of the core component battery pack, that is, the battery pack is an important component to determine the performance of the vehicle. When using that kind of battery, you need to pack the whole battery to ensure that the vehicle can have high-quality power supply when driving. At this time, you need a good battery box to ensure the safety of the battery pack. But also has a certain strength, stiffness and heat dissipation performance advantages, then the advantages of carbon fiber battery box is very good to show.
The actual use of carbon fiber battery box needs to consider the space factor, but also to consider the overall safety and performance of the vehicle. That battery box needs to have these characteristics:
1. Insulation performance
In the use of new energy vehicles, the power source of the whole vehicle is the automobile battery, that is, the insulation performance of the automobile battery box should be very good, and the output voltage of the automobile battery can reach 220 v. in this case, the battery box should not only ensure the volume of the battery and human battery, but also isolate the contact between the battery and personnel, so as to avoid electric shock and leakage.
2. Waterproof performance
The battery pack should have good water resistance to ensure the overall sealing, otherwise it is easy to lead to short circuit of the battery and frequent failure. So sealing is a very important performance parameter in the battery box.
Then, in order to ensure the sealing and waterproof of the battery box, it is necessary to keep a certain distance between the connecting plate of the battery box and the junction plate of the battery box, and then conduct insulation spraying inside to ensure the further improvement of the insulation of the battery box.
3. Safety
In the process of driving, the car often collides, so for the battery pack in the case of vehicle collision, it should not cause secondary harm to the box, such as box moving, secondary harm. In addition, in the case of collision, the battery box is scattered, and in the case of collision, the battery pack in the battery box will not be short circuited due to collision.
Then, under the three performance requirements, the advantages of carbon fiber battery box are fully demonstrated. Carbon fiber battery box is light in weight, but its strength is five times that of steel. However, the quality is only one fifth of that of steel. Compared with steel, it has better strength performance. In case of collision, it can also better ensure the safety of the whole battery pack. Moreover, the corrosion resistance of carbon fiber battery box is better, which can better ensure the internal safety of the battery box and ensure more effective performance transmission of the battery. Moreover, the design of carbon fiber battery box is better, which can ensure the excellent performance in case of collision in practical application.
Naturally, it has lighter weight, which can further reduce the overall weight of the vehicle, improve the overall endurance of the electric vehicle to a certain extent, and also improve the performance of the vehicle
