Abstract:

The status of new energy vehicle technology and the existing hydrogen-electricity energy and infrastructure construction are analyzed. The technical difficulties brought by the transformation of automotive energy network is also discussed, The concept of traffic electric-hydrogen binary secondary energy network is proposed to achieve the goal of optimizing energy conversion efficiency chain and circulating the material utilization in transportation area. The three technical problems of renewable energy power stability, energy consumption and large-scale concurrent charging of electric vehicles are analyzed, and corresponding solutions are also proposed. Since both of the electric energy and hydrogen energy have the characteristics of widerange of sources, renewable, emission and pollution controllable, it has become the key point for the future transportation and energy technology to build an automotive power system with electrification as the core and an energy network system with two secondary energy sources of electricity and hydrogen.

Key words:  new energy vehicles , electric drive ,  hydrogen energy , energy transition , electricity - hydrogen electricity binary secondary energy network
