Development of Wireless Battery Monitoring for electric vehicle

A Wireless Battery Monitoring System (WBMS) for electric vehicle has been developed for monitoring voltage, current and temperature of battery. This system consists of hardwares (sensors, a microcontroller, a bluetooth module, an Android smartphone) and software. It was designed on a low cost microcontroller ATMEGA 328 (Arduino UNO). Voltage, current and temperature data are transfered to microcontroller, then data of battery is transfered using bluetooth communication to display. In this research, data of battery monitoring are displayed on Personal Computer (PC) with LabVIEW programme and android smartphone. The monitoring system was able to show real-time data of voltage, current and temperature and display data on android smartphone and PC simultaneously.
