Electric Vehicles Battery Management Network Using Blockchain IoT

Electric Vehicles (EVs) have generated a lot of interest in recent years, due to the advances in battery life and low pollution. Similarly, the expansion of Internet of Things (IoT) allowed more devices to be interconnected. One major problem electric vehicles face today is the limited range of the battery and the limited number of charging or battery swapping stations. A solution is to not only build the necessary infrastructure, but also to be able to correctly estimate the remaining power, using an efficient battery management system (BMS). For some EVs, battery swapping can also be an option, either at registered stations, or even directly from other EV drivers. Thus, a network of EV information is required, so that a successful battery charge or swap can be made available for drivers. In this paper, a blockchain implementation for an EV BMS is presented, using the IOTA tangle as the network and data layer of the application.
