Electric vehicle green power consumption traceability method and system

The invention relates to the related technical field of green energy, in particular to an electric vehicle green power consumption traceability method and system. The method comprises the following steps: acquiring charging information of an electric vehicle charged by preset charging equipment; acquiring power source information of the preset charging equipment; wherein the power source information comprises whether the power is renewable energy; and carrying out green power consumption traceability on the electric vehicle based on the power source information and the charging information by adopting a block chain technology and an intelligent contract. According to the arrangement, by means of the block chain technology and the intelligent contract, it can be ensured that transaction records and traceability information cannot be tampered, and the safety and reliability of data are enhanced. By acquiring the charging information of the electric vehicle and the power source information of the charging equipm
