This paper presents a Battery Monitoring and Control system for an electric vehicle to monitor the voltage, current, and temperature of the battery and detect fire. This system consists of hardware (sensors, microcontroller, Bluetooth module, an android Smartphone) and software. It is designed with a low-cost microcontroller ATMEGA 328 (Arduino UNO). Voltage, current and temperature data are transferred to the microcontroller, and then the battery data is transferred using Bluetooth communication to the Android Application. In this work, monitoring the vehicle's parameters using an Android application is proposed so that the monitoring can be done directly. The proposed battery monitoring system is consists of two major parts i) monitoring device and ii) user interface. In this proposed system, an indication of the battery's voltage, current, and remaining charge capacity is monitored in a real-time scenario, and appropriate control measures are initiated. We have developed a data acquisition system to monitor these battery parameters by building a PIC-based system. Further, data are also displayed on an Android mobile device and are stored in a server database. A realistic model is developed here to create the final product for the proposed system.
