Abstract： In recent years, under the vigorous promotion of the state, the fields of new energy charging piles and electric vehicles have developed rapidly, but there are also negative situations such as leakage of transaction information, difficulty in sharing data between enterprises, and poor user charging experience. Based on the above problems, the article proposes a new energy charging management plan based on blockchain, using the characteristics of blockchain such as decentralization and data encryption, using Bitcoin on the bottom of the blockchain and joint representation recommendation algorithm and other technologies, three modules including alliance chain module, charging coin module and recommendation module are established, and a set of distributed new energy electric vehicle charging management scheme based on blockchain is proposed. Practice has proved that this scheme can better solve the above-mentioned problems.
