Lithium battery remote monitoring system for vehicle mounted

摘要

In order to improve the real time monitoring ability and safe operation of the electric vehicle lithium battery, save the cost of battery, this paper presents a remote monitoring system for lithium battery of electric vehicle. Which is composed of the vehicle information collector and the upper computer. The collector of vehicle information is composed of microprocessor, CAN bus controller, GPS module and GPRS module. The collector is connected with the CAN bus and the central control system of the electric vehicle by ECU. It will receive the lithium battery information and GPS data through the GPRS network to transfer to the host computer. PC software system use C++ and Oracle database to develop, to analyze and to handle the information of battery and locate electric vehicle, to ensure the stability and efficiency of data storage. The system has entered the testing phase. It has been achieved for the monitoring of lithium battery information. It has good stability, low cost, high reliability.
