The art of balancing lightweight and practicality

The overall weight of a vehicle is a major factor that limits the performance of new energy vehicles. Lightweight technology can significantly increase the driving range of new energy vehicles by reducing the vehicle's weight. Therefore, the overall lightweighting of the vehicle body has become one of the important development directions in the industry. Among them, the slimline battery tray is an important component of the new energy vehicle's power system. The driving conditions of a vehicle are very complex, and various factors such as road conditions, weather, and unexpected accidents need to be considered. This requires it to have multiple composite properties such as high precision, corrosion resistance, high temperature resistance, and impact resistance. Therefore, the dual battery tray is not only a container for batteries but also needs to take on the responsibility of ensuring the overall safety of the battery system.

The overall structure of an automotive battery system can be roughly divided into the power battery module, structural system, electrical system, etc. Among them, the structural system mainly consists of the universal battery tray, which serves as the skeleton of the battery system and accounts for 20% to 30% of the total weight. How to ensure its safety performance under the premise of lightweight development is the main issue in the development of the structural system.

Why Choose Aluminum Materials

New energy vehicles use batteries as containers, and the structural system plays a crucial role in ensuring the safe operation of the batteries. The selection of materials for this system has always been an important research topic. Steel battery boxes mainly use high-strength steel, which has the advantages of simple processing, high welding performance, and low material cost. It also has excellent safety protection performance. However, its limitations are also obvious. It is very heavy, which greatly limits the driving range of electric vehicles; it has good impact resistance but poor rigidity, and once it is deformed by compression, it can easily cause damage to the internal batteries or even lead to accidents; at the same time, the corrosion resistance of steel is poor, which greatly affects the lifespan of the overall structure.

In response to these issues, the current market mainly uses aluminum as the primary material for battery tray holders, with extruded aluminum alloys being the mainstream design solution. This material can be flexibly adjusted according to the design style, and it has been optimized to address the shortcomings of steel. In terms of weight, aluminum is lighter, and in terms of performance, it has better rigidity and shock resistance.

Not only lithium battery trays, but also car bodies, doors, and other components are considering and attempting to use aluminum frames.

Die-casting is also a common manufacturing method. Compared with extrusion, its advantage lies in the fact that it can be formed in one piece without welding, thus having better overall performance. However, it also inherits the defects of die-casting, such as common cracks and pores. Additionally, the elongation of cast aluminum alloys is relatively low, making them prone to deformation. Moreover, the die-casting process itself has certain limitations, and large-capacity under-tray battery boxes cannot be produced using this method.

Aluminum extrusion and aluminum die casting are currently the two main production processes. The former offers better structural strength, while the latter has higher production efficiency. The design of automobiles is always a holistic process rather than a local one. For instance, with the promotion of battery swap stations, future cars will need to withstand frequent battery removal and reinstallation cycles. This implies that the Optima battery tray must possess the characteristics of quick disassembly and assembly, high durability, and standardized interfaces. Therefore, the development of automated and intelligent production lines is an inevitable direction for improving production efficiency and product consistency.
