For even worse cases, it may spontaneously combust and detonate. Therefore, safety issue has become a primary restriction factor for commercial promotion of car Li-Ion starter battery. Being the core of battery protection and management, Battery Management System not only ensures the reliability of the battery usage, it also maximizes the bat-tery’s capability and life. Furthermore Battery Management System has become a communication bridge between battery and vehicle management system and drivers. Thus, as for improving vehicle efficiency, Battery Management System is now playing a more and more critical role. The present research focuses on the research and production of Li-Iron Starter Battery Management System. This system includes the design of Bluetooth module transmis-sion, the establishment of cloud database, and the interface design of the relevant An-droid App. The battery module statistic data of total voltage, string voltage, current and temperature will be uploaded via Bluetooth to instantly display on the App on mobile devices, and it will further be uploaded to cloud database for storage and analysis via the mobile devices’ wireless function or WiFi. Once the Battery Man-agement System detects abnormal value, it will instantly send a warning signal to the App on user’ s mobile device and provide instruction to deactivate the protection mechanism of the Battery Management System. With this Li-Iron Starter Battery Management System, users themselves can instantly monitor the vehicle electrical system and the battery status. By long-term collection of data, battery producers will be able to provide the service of tracking and fix problems on battery usage.
