In the V2G power trading, electric vehicles are not simple energy consumers but production investment consumers. When the power consumption of the power grid is in a low ebb, the electric automobile purchases electricity from a charging pile user; when the power consumption of the power grid is in a peak, the electric automobile sells the electric power purchased in the valley to the charging pile user, and the income is obtained from the electric power.
The invention provides an energy data tracing method based on a block chain technology, which aims to meet the requirement of tracing data in the transaction process of an electric vehicle, and mainly aims at data tracing of business information generated in the transaction process of the electric vehicle. The following is a brief description of the business data that may be generated during the transaction:
in the transaction preparation process, a charging pile user serves as a transaction initiator, logs in a transaction system and sends information to be transacted, wherein the information to be transacted comprises but is not limited to transaction cost and service cost of an electric vehicle; after the successful release, the current node broadcasts to all the block link nodes, and finally generated service information of the information to be transacted includes but is not limited to a transaction initiator, the transaction cost of the electric vehicle, the service cost and the release time.

As an alternative, the feasibility verification: when the transaction is an electric vehicle charging transaction, when the transaction electric quantity of a user is smaller than the residual electric quantity of the charging pile, the request is successful; otherwise, the request fails, and the user re-declares the transaction electric quantity; when the transaction is an electric vehicle discharge transaction, judging whether the transaction electric quantity of a user is smaller than the maximum chargeable quantity of the charging pile (the charging pile stores the maximum electric quantity-the charging pile residual electric quantity), if so, successfully requesting; if not, the request fails, and the user re-declares the transaction electric quantity.
The charging pile user serves as a transaction initiator, initiates a confirmed transaction message, generates business information of transaction uplink information including but not limited to the transaction initiator, a transaction responder, transaction electric quantity, electric vehicle transaction cost, service cost and transaction time, and broadcasts to all block link points by the current node.
