The U.S. Environmental Protection Agency said that for every 100 pounds of car weight reduction, fuel economy will increase by 1-2%. The electric car industry is working to improve energy efficiency and alleviate "range anxiety", which undoubtedly brings business opportunities. The battery encapsulation shell of an electric vehicle is mainly used...
