**8. Conclusions and Future Direction**

With the gradual increase in environment-friendly electric vehicles, the availability of charging stations should be ensured. However, it is not an easy task anyway to make them available everywhere, especially in rural areas. Our proposed method largely solves this issue, as it uses an approach of enhanced peer-to-peer charging of EVs, which would increase the availability of charging stations without much change to the existing infrastructure. It will use the same areas but will employ a mechanism to make bonds between the EVs and charging stations anywhere. The rating system can be very useful for keeping the market prices in check and ensuring the quality of the service.

The transactions without a third party are made safe via integrated blockchain to secure the environment for the member nodes of the blockchain for trade. Moreover, a cryptocurrency-based payment system makes the system easy, automated, hassle-free, timesaving, durable, environment-friendly, immutable, and available worldwide. Furthermore, enhanced technological support structures, such as edge computing, and high-speed 5G/6G Internet, can be easily combined with the system to make it more efficient. In the future, we plan to integrate the proposed system with real EVs and HCSs and collect real-world data from those, and make necessary arrangements to enhance the quality of service.
