Battery swapping is a solution of electric vehicle (EV) battery refueling. For EV owners, the battery information and transaction's correctness, openness, traceability and immutability is difficult to get guarantee in traditional centralized system. The trust lacking between EV owners and swapping station is caused, and becomes a big challenge to EV's rapid development. An objective mechanism based on decentralized blockchain system is proposed to manage battery swapping and solve the trust

All key logics are driven by smart contracts, the battery price calculation and the digital currency exchange between EV owners and station are realized by smart contracts automatically and accurately. A primary prototype based on Ethereum is analyzed and implemented to illustrate the feasibility of managing battery swapping and refueling based on blockchain system to solve the trust lacking issue.
