EV battery case, also known as EV battery box, is one of the most important components in new energy vehicles. The best NEVs make use of aluminum alloy for the battery case structures as key components that offer security for their battery payloads, but also structural rigidity for the vehicles. Our battery case has high-temperature resistance, corrosion resistance, high electrical conductivity, and good heat transfer performance. Large scale battery case castings are an exciting area for die cast aluminum casting technology.
The main purpose of the battery shell of an electric vehicle is to accommodate and protect the battery. They come in different shapes and sizes, and aluminum and steel are the traditional materials for battery housings. The main obstacle to the large-scale adoption of electric vehicles is the fear that they will not be able to drive far enough on a single charge. Composite materials can provide an improved alternative to significantly improve the performance of electric vehicles. In order to alleviate this problem, it is necessary to provide qualified cars, and the parts that make up them must also have these qualities.
Lose weight. The main driving force for choosing composite materials is that if the shell is made of 100% composite materials instead of aluminum, weight savings of up to 40% can be achieved, which will play an important role in the large-scale adoption of electric vehicles.
Reduce noise. Noise is the result of acoustic propagation of vibration or noise in the cabin.
Although not obvious in other ways, it is important in terms of commerciality and driving experience.
Security issues. The strength and stiffness of the composite battery shell exceeds that of aluminum or steel and can be designed as part of the body structure to protect not only the battery but also the passengers.
Pultrusion. Mass production is essential to reduce overall costs.
Continuous manufacturing methods can be used to produce battery box components for electric vehicles, and Pultrusion process can be used to produce stronger but lighter products.
