Online Battery Monitoring System Based on GPRS for Electric Vehicles

Electric vehicles which has the advantages of energy saving and environmental protection, are brought to global attention as an energy crisis and climate change. Electric vehicle battery technology is one of the hotspots and difficulties in electric vehicle research in recent years. From a business perspective, capable of grasping the working status of electric vehicle battery in real time, in order to put forward a control strategy for extending the battery life is very necessary. This paper proposes a novel online battery monitoring system for electric vehicles Based on GPRS wireless communication. It consists of online monitoring terminal for battery parameter measure with GPRS date transmitter unit and an upper computer with a battery online monitoring system software, and can monitor the various operating parameters of the battery in real-time, judge the status of the battery and fault diagnosis, and establish a database to facilitate data storage and find. Meanwhile, it develops hardware and software by building hardware and software test platform. Test data are obtained to verify the reliability and feasibility of the monitoring system.
