Mobile charger billing system using lightweight Blockchain

Abstract

Green transportation such as electric vehicles are emerging as an alternative to the traditional vehicles primarily due to the increasing cost and need of petroleum energy worldwide. These electric vehicle operate by using electric charging and the way to charge an electric car is to use a mobile charger or use a charging infrastructure. Therefore, when a mobile charger is used, a billing system is required through which a user is billed who has charged the electric vehicle. In this paper, we propose a mobile charger billing system that utilizes Blockchain technology. This technology has been applied to achieve more secure online transactions in a peer-to-peer manner. Moreover, we analyze the requirements of mobile charger for billing and propose a lightweight scheme that can overcome the challenge of data size in existing Blockchain.
