汽车电动化与汽车交通电-氢二元二次能源网络构建

Electrification of automobile and construction of electricity-hydrogen binary secondary energy network for automobile transportation

对新能源汽车技术现状、现有氢、电能源基础及基础设施建设等能源转型的先决条件进行了分析,提出了汽车交通“电-氢二元二次”能源网络的概念,以期实现交通运输中能量转换效率链的优化和物质利用的封闭循环,并对能源网络转换带来的可再生能源发电入网的稳定性、能源消纳和电动汽车大规模并发充电这3个关键技术问题进行了分析,提出了相应的解决方案。由于电能和氢能具备来源广泛、可再生、排放及污染可控的特征,构建以电动化为核心的汽车动力系统和以电、氢两种二次能源为核心的能源网络成为未来汽车交通体系的关键策略。

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.
