Exploring Blockchain enabled Smart Community with Electric Vehicles

The demand for Electric vehicles (EV) are growing day by day. But the power grid is operating in bottleneck to meet customer power requirements. Blockchain technology is being used in applications that involves transaction between untrusted entities. We propose blockchain enabled energy pooling platform with smart buildings and EVs. This platform enables peer to peer energy transactions between buildings and EVs. Rooftop photovoltaic (PV) systems generate power during daytime and utilised by the loads. We propose, EVs to store the excess energy generated from the rooftop PV system. EVs will discharge the stored energy during night or when there is an energy demand. We have demonstrated this concept with two use cases using Ethereum Platform on Google Cloud Platform. We also developed a Fuzzy Logic based smart contract to decide incentives for energy storage and discharge. We envision that this platform will help EV owners, OEMs and grid operators to maximise their system efficiency and help recoup their investment.
