15. IOT BASED SMART ENERGY METER AND COST MONITORING SYSTEM FOR EV CHARGING STATION

In the world of emerging technologies, automobile manufacturers all over the world are currently developing electric vehicles with different features based on the requirements of the people. Electric individuals are interested in using electric vehicles transportation because they are environmentally beneficial .Because they are powered by batteries, electric vehicles are becoming more and more popular.The Smart Energy Metre (SEM) has been created in the proposed concept power level indication and alert system for ele ctric vehicles. Through IOT, this gives the user graphical representations of current and voltage information. The user can use this metre determine the battery's state and the location of the charging station. The battery is calculated and monitored using a voltage sensor. Light indications warn the user if the battery is low. When the battery colour otherwise glows in green colour. Communication between user and vehicle during which the customer requests SEM is usually done in a short period i.e., less than a minute. /Relay is used for switching purposes, it controls the flow of charge in the system.
