Analysis on Profit Model of Free-charging Equipment in Public Place

In this article, we forecast the future holdings of electric vehicles. And the sales growth rate, and then get the growth of the charging demand. In this way, the change in energy consumption caused by charging can be identified. Then we set up a cost model and an income model. The model can be utilized to obtain obtain the key factors that affect the cost and benefit of charging in public places. Then, we summarized the advantages and disadvantages of the cost model and the benefit model, combined with our findings in the simulation verification process, and put forward some reasonable suggestions on how to reduce the cost.
