The design of semi trailers has evolved dramatically over the years. The introduction of lightweight materials such as aluminum and advanced composites has made modern semi trailers not only more robust but also significantly lighter. This weight reduction translates to increased cargo capacity and improved fuel efficiency. Moreover, aerodynamic designs are becoming the norm, enabling trailers to cut through the air more efficiently, reducing drag and, consequently, fuel consumption. This innovation is critical in an industry where fuel prices can significantly affect operational costs.

One of the most significant factors in the cost of electric vehicles is the battery. Batteries account for around 30-40% of the total cost of an EV power car, but as technology improves, battery prices are rapidly declining. EV power solutions have made significant progress, with innovations like solid-state batteries, more efficient lithium-ion cells, and better-charging infrastructure. These improvements not only enhance the performance and range of new energy-electric cars but also contribute to reducing overall production costs.
