Implementation of algorithm to determine estimated state of charge, travelling time and distance to cover for electrically powered vehicle

Abstract

Electrically assisted with PV panel supported vehicle is developing a market for the automobile manufacturers as it is a promising innovation in case of reducing CO2 emissions and fossil fuel consumption. The number of electric vehicles on the road is not up to the expectation due to some constraints which includes limited driving range that depends on many factors such as load type, driving style and road condition. The paper describes the development and implementation of an algorithm to produce and install a useful electrical device on the electric vehicle which will show State of Charge (SOC), remaining discharging time of battery and available travel distance correspond to SOC on the LCD display by using microcontroller along with necessary external electrical connections with required components. This electrical device provides the features for the puller to take the decision about charging the batteries used in the vehicle in time which helps to avoid unwanted risky occurrence in the middle of the road due to limited driving range. This project include a brief description of the method used to develop the algorithm and also describes the data obtained from the field test which assures performance, efficiency and feasibility of the electrical device.
