Batteries replace the original gasoline and are the most important source of power for electric vehicles. Generally installed in the lower part of the electric vehicle body. Currently commonly used batteries include lithium iron phosphate batteries and ternary lithium batteries.
The battery cannot be directly exposed to the outside and needs to be placed in a battery box. At present, the overall performance of carbon fiber battery boxes is better.
The density of carbon fiber composite materials is about 1.7g/cm3, which is much lower than steel and even lower than aluminum. In addition, the strength of carbon fiber composite materials is five times that of steel and much higher than that of aluminum. To sum up, carbon fiber composite materials are one of the most suitable materials for the development of lightweight automobiles.
The battery box made of carbon fiber composite materials can reduce the weight by about 70%, and its protective effect is no worse than that of steel plates and aluminum alloy boxes, or even better. Carbon fiber composite materials also have good acid and alkali corrosion resistance, salt resistance, oxidation resistance and impact resistance. In the daily use of electric vehicles, it can play an effective protective role, isolate the impact of environmental factors on lithium batteries, and truly help new energy vehicles improve the driving experience.
