Research has shown that for every 10kg reduction in weight of pure electric vehicles, their range can increase by 2.5km.

In today's world where the utilization of space inside the battery pack is becoming increasingly limited and it is becoming increasingly difficult to improve battery energy density, the weight reduction of the battery system will become another important breakthrough point in increasing the range of new energy vehicles in the future.

At present, lightweight battery pack PACK designs often use aluminum alloy and SMC materials. Due to the limitations of performance parameters such as material strength, this type of PACK material requires a large amount of material, resulting in insufficient weight reduction effect of the battery pack.

Carbon fiber composite materials not only have lower density than SMC and aluminum alloy, but also have much higher strength. Therefore, when using carbon fiber for lightweight development of battery packs, overall redesign can be carried out based on structural strength, which can significantly reduce the quality of the battery system.
