Economic benefit analysis of battery charging and swapping station for pure electric bus based on differential power purchase policy: a new power trading model

Battery charging and swapping station (BCSS) has great assistance for the development of Electric vehicles (EVs) and environmental protection, but its economic performance is poor. This paper aims to explore the feasibility of direct power trading in the charging and swapping market by comparing the economic benefits of BCSS under three different power purchase models. Firstly, this paper summarizes the differences between the three power purchase policies. Then, the environmental benefits of clean energy and coal power generation are compared. Finally, based on the cost-benefit theory, a pure electric bus BCSS in North China is taken as an example to analyze the benefits of the three power purchase models. The results show that compared with coal power generation, the use of clean energy has good environmental benefits. Compared with the other two models, the direct power trading model can significantly increase the project's NPV and IRR, which demonstrates that it can make up for the investment cost well. Some suggestions are put forward to improve the economic benefits of BCSS enterprises and promote the development of EVs. The research results can provide a reference for decision makers and investors.

Automated summary

This study compares the economic benefits of Battery Charging and Swapping Station (BCSS) under three different power purchase models and finds that the direct power trading model significantly increases the project's Net Present Value (NPV) and Internal Rate of Return (IRR), making up for the investment cost. Additionally, it reveals that the use of clean energy has better environmental benefits compared to coal power generation.
