In recent years, Dynamic Wireless Power Transfer (DWPT) technology has gained interest within the market of charging systems for electric vehicles. This technology can potentially boost the diffusion of electric vehicles (EVs) and consequently contribute in reducing the local air pollution and the related externalities.

In this context, an environmental and economic analysis has been performed to estimate the social costs saving derived by the decarbonization of the passenger cars mobility. The benefits evaluated in the analysis are compared to the investment and maintenance costs necessary to install and operate a DWPT infrastructure. This under the basic assumption of the present work that considers the widespread adoption of electric vehicles achievable only in presence of the parallel integration of DWPT systems in the motorway infrastructure. At the same time, the work takes into account the possible variations of the energy mix and the effects related to the increase of the electric energy demand related to the increase of the circulating electric vehicles.

The analysis is carried out for the six most populous European countries (i.e. Italy, France, Germany, Poland, Spain and UK) and it indicates as the estimated social costs savings are capable to sustain the investment for a wide integration of DWPT in almost all these countries.

近年来，动态无线电力传输（DWPT）技术引起了电动汽车充电系统市场的关注。这项技术可能会促进电动汽车（EV）的普及，从而有助于减少当地的空气污染和相关的外部性。

在这种情况下，已经进行了环境和经济分析，以估算因乘用车机动性低碳化而节省的社会成本。将分析中评估的收益与安装和操作DWPT基础结构所需的投资和维护成本进行比较。这是在本工作的基本假设下考虑的，只有在高速公路基础设施中存在DWPT系统的并行集成的情况下，才能实现电动汽车的广泛采用。同时，该工作考虑了能量混合的可能变化以及与与循环电动车辆的增加相关的电能需求的增加相关的影响。

该分析是针对六个人口最多的欧洲国家（即意大利，法国，德国，波兰，西班牙和英国）进行的，该分析表明，节省的估计社会成本能够维持几乎所有国家DWPT广泛整合的投资这些国家。
