Charging piles are used for charging electric vehicles and are directly accessible to users in an energy internet entrance

while playing an important role in energy consumption. Currently

each enterprise constructs the center of operation and maintenance of their systems independently

along with their respective APP payment programs. This results in high operating costs

poor user experience

and low utilization rate of the pile

which limits the promotion and popularization of electric vehicles. To overcome this limitation

there is a need for a multi-center

fair

and transparent consortium blockchain

which can conform to the application requirements of a unified payment system and accommodate a range of diverse enterprise charging piles. In this paper

the design for a consensus and incentive program for consortium blockchain is presented. First

the application status of blockchain in an energy internet is described. Then

the logical structure and hierarchical model of the consortium blockchain are analyzed. Next

multicycle accounting and limiting the amount of accounting nodes in each round is presented to ensure the overhead of consensus remain constant. Finally

the accounting incentive mechanism and the bidding encouragement strategy based on "electric beans" are designed.
