A resolution of sharing private charging piles based on smart contract

With the popularity of electric vehicles, more and more charging piles were built. All of the private piles only serve for their owners, and are left unused for a longer time comparing to public piles. In order to keep private piles busier, meanwhile providing alternatives to electric vehicle users when charging, this paper designs a resolution for sharing private piles using blockchain and smart contract. Without the third party, we can do untrusted payment between strangers after charging; the access control strategy in this resolution protect the data privacy of transactions.
