Charging transaction management method and system based on block chain

Abstract

The invention provides a charging transaction management method based on a block chain, and belongs to the application field of electric vehicle charging transaction. The method comprises the steps of: calculating a service charge unit price of a charging service of a user according to a user reputation value; according to the unit price of the service fee, calculating the charging fee needing to be paid by the user at this time; after the user settles the charging fee, updating account book information between the operator and the platform according to user information of the user, operator information and current charging settlement data; broadcasting and storing the account book information to a block chain network to a charging pile node, and packaging and chaining the account book information into a block at the charging pile node; obtaining the score of the user for the charging service; calculating a service score value based on the user score and the user reputation; and broadcasting the updated service score value to a block chain network, storing the updated service score value to a charging pile node, packaging the service score value into a block at the charging pile node, and carrying out chaining. The invention further provides a charging transaction management system based on the block chain.

Description

technical field [0001] The present invention relates to the application field of block chain technology in electric vehicle charging transactions, in particular to a block chain-based charging transaction management method and system. Background technique [0002] With the popularization of the concept of energy saving and emission reduction, and the country's promotion of the new energy market, the proportion of the use of new energy vehicles is increasing significantly. Correspondingly, the demand for charging piles is also increasing, and charging pile operators have also begun Construction of charging piles and industry competition. [0003] At present, the domestic construction of new energy vehicle charging piles is still in its infancy, and there are problems in the charging infrastructure construction and operation management model: for users, there is not enough restraint mechanism, there are problems of delayed payment and untimely settlement; for charging In term...

Problems solved by technology

[0003] At present, the domestic construction of new energy vehicle charging piles is still in its infancy, and there are problems in the charging infrastructure construction and operation management model: for users, there is not enough restraint mechanism, there are problems of delayed payment and untimely settlement; for charging In terms of pile maintenance and operation, operators cannot timely understand the user experience of charging piles. Users will avoid charging piles with poor user experience and choose to wait for charging piles with good user experience. There are often cars with no piles, and vehicles with multiple piles. uncoordinated development
