The invention relates to an electric vehicle charging pile sharing platform control method based on a block chain. The method specifically comprises the following steps: S1, enabling a public chargingpile operator, a private charging pile manager, an electric vehicle aggregator and an electric vehicle user side to register; s2, respectively issuing charging pile information and charging demand information; s3, performing off-chain matching on the charging pile information and the charging demand information; s4, broadcasting the matching result of the off-chain matching to each charging pilenode, and judging whether the corresponding electric vehicle user end reaches the corresponding charging pile for charging according to the target charging time or not; s5, after charging is completed, carrying out settlement, account transfer and credit degree updating through the intelligent contract, packaging transaction data blocks, and forming a block chain. Compared with the prior art, thecharging pile has the advantages that the utilization rate of the charging pile is increased, and the charging requirements of electric vehicle users are met immediately.
