In 2HOD,
electric vehicle (EVs), which represents the step forward towards a sustainable mobility. From the statistics, transportation sector contributes over 25% of the CO2 emissions and 50% of the oil consumption this causes air pollution which is leading to the increase in temperature and also leads to the Global warming. Electric vehicles (EVs) should be replaced by the fuel vehicles this is the major solution to decrease the air pollution because electric vehicle (EVs) are zero emission which does not affect environment. Where, here engines are replaced by a battery the Lithiumion battery is typically the best battery for electric vehicles (EVs). Battery management system(BMS) plays a crucial role in management of controlling the battery. Due to the limitation like electrical power distribution limitation, Electric Vehicles (EVs) charging should perform in a effective way. This proposed system for a Electric Vehicle (EVs) utilization and charging system having many advance features. The proposed device will automatically stop the overcharging and charging will not happen in battery and different parameters will monitor based on the parameter battery charging and utilization for a load and it will be controlled automatically in this implementation.
addition to this a primary function of battery protection the Battery Management System (BMS) should be able to estimate the battery status in order to predict its actual amount of energy that can still be delivered to the load and this is a quite challenging task, as the performance of the battery in terms of usable internal resistance and capacity varies over time. This project is making electric vehicle (EVs) battery management system using the automatic technique. By using this technique the system battery input and output will be managed. Once the charging starts, that will stop automatically when the charging is done and load will be control automatically based on the different parameter like temperature and charging status. User will able to see all information using LCD display.
2. DESIGN OF PROPOSED SYSTEM Here, main supply we are using for charging source here in this section we are using step down transformer for converting the voltage high to low, Rectifier Bridge and filter are used at charging source. This source will connect with battery for charging through the charging relay. This charging relay will automatic trigger off after the charging is done. This relay will off by microcontroller section. Microcontroller will get charging status and condition with help of different sensor like, current sensor and temperature sensor. This senor will send battery information to microcontroller and microcontroller will display all the values to user using LCD display and also by IOT server.
Key Words: Micro-controller, IoT Module, Electric Vehicles(EVs), BMS, Electric sensor, Voltage sensor.
1.INTRODUCTION Electric vehicles(EVs) plays an important role in sustainable mobility thanks to the zero–emission and efficient energy utilizesation. The battery has an great impact on the performance of the electric vehicles (EVs), basically it is determining the driving range. As a consequence, the battery technology and its effective utilization is of paramount importance. From today’s perspective, Lithium-ion chemistry is one of the battery technology of choice due to the good power rating, good energy density, and charge/discharge efficiency in a pulsed energy flow system. Usually, a large number of cells depending upon its application are series connected to build the battery string with a required voltage.
Based on charging level in battery the microcontroller will control the load and if the battery has very less charging, the controller will trigger off the load by using load relay section. All management of battery will be automatically executed.
Li-ion chemistry is sensitive to deep discharge and overcharge, which may damage the batteries and also shortens its lifetime and also even causing hazardous situations. For this it requires the adoption of proper Battery Management System (BMS) to maintain its each cell
