BATTERY MONITORING SYSTEM FOR ELECTRIC VEHICLES

This book summarizesThe Electric Vehicle is preferred mainly because it is less expensive and environmental friendly. But it comes with the problem of battery overcharge and deep discharge. This problem affects battery life and performance over the years. To overcome this problem, the proposed system gives the prototype for Battery Monitoring System for Electric Vehicles (EV), in which different battery parameters such as voltage, current, power and the temperature are monitored by using various sensors. The measured battery parameters i.e., voltage, current, power and temperature data is sent to the Arduino UNO and the battery information is displayed on LCD and communicated to the user through Android smartphones. If the temperature exceeds the threshold value, then thermoelectric plates will automatically on and cool down the battery. The proposed system is also supported with a dual battery mechanism so that if one battery gets discharged then another battery will automatically connect. This mechanism helps in back up of the power when one battery is discharged.
