Block-chain based Energy Tracing Method for Electric Vehicles Charging

In order to promote the healthy interaction of the ecological platform for renewable energy production-trading-distribution-consumption with the electric vehicles (EV) market, this paper introduced the block-chain based renewable energy tracing method to track the EVs' charging consumption regarding to renewable energy's type and source. With the technical features and advantages of block-chain, it has established the mutual trust and resource sharing platform: “renewable energy tracing for EV charging”. The platform integrated Beijing Power Trading center, Qinghai power dispatching center, Smart Internet of Vehicles Platform, local power operators and EV charging users by applying block-chain; introduced the tracking and matching mechanism of renewable energy products for EV charging orders, and established the infrastructure for the formation of EV renewable energy consumption certification by using smart contract, which formed the basis digital certification of EV renewable energy consumption.
