On July 14, 2021, the European Commission released a package called "fit for 55", which requires member states to accelerate the construction of new energy vehicle infrastructure to ensure that there is an electric vehicle charging station every 60 kilometers on major roads; in 2022, European countries have introduced specific policies, includin.
In March 2020, the central government stipulated that construction of charging piles for new energy vehicles is among the seven major new infrastructures. Therefore, attention and support to construction of charging infrastructure are growing increasingly.
From Section 2, we conclude among the four kinds of subsidies for the construction of charging piles in China, total investment subsidies, power subsidies and construction + operation subsidies are the main forms of subsidies.
The subsidy modes of S2 (Shenzhen mode) and S3 (Shanghai mode) are related to the power of charging piles, which makes the effect of subsidy on the economic benefits of charging piles increase with the increase of the power of charging piles.
The subsidy for EV charging facilities mainly comes from the government's one-off subsidy. According to the Section 2, the subsidy standards of different provinces and cities in China are different. However, the number of subsidies that the builder ultimately receives can be related to the number of charging piles.
In operation, public charging facilities are subsidized at the standard of 0.2 CNY/kWh, and the maximum annual allowance for kilowatt charging power is 1000 kW h/year. Based on the business model mentioned in Section 3, the full life cycle economic analysis of the three charging modes under different subsidy forms are obtained.
For 350 kW high-power ultra-fast charging mode, the form of power subsidy is more conducive to improving its investment economy. Through sensitivity analysis, it is found that the utilization rate of charging piles and the price of charging service fees are the two most critical factors affecting the economic benefits of charging piles.
