[Automotive Materials Network] Power battery packs are the core of electric vehicles
One of the components, the weight of the battery pack
approximately The total weight of the vehicle is 20-30%, and it is also one of the components with the highest cost in vehicle production. As we all know, the battery pack has very strict requirements for safety, and it also determines the performance of the vehicle in terms of power and cruising range.
To improve performance, the overall weight of the body is also critical. Among them, the lightweight problem of battery packs, which account for nearly one-third of the weight, has also become the key.
Why should the battery pack be lightweight?
Research data shows that the weight of traditional fuel vehicles can be reduced by 10%, and the economy can be improved by 6-8%;
Under constant speed driving conditions, the weight of electric vehicles is reduced by 10%, which can increase the driving range of the vehicle by about 10%.
