Research on Electric Vehicles with Design of Battery Test System Based on LabVIEW

Testing the parameters such as state of charge (SOC), temperature and current of power battery under different running status is very important to adjust control parameters of system in time. A battery test system based on LabVIEW is designed. USBCAN-II produced by ZLG is used to bear the communication tasks of CAN bus. Two AC motors and inverters are used as energy converters and they are mechanical parts of the system. Inverters communicate with PC software via 485 bus. The PC software based on LabVIEW is used to display, store and analysis the error of the data received. After a detailed test, it is shown that the system has the advantages of accurate and rapid detection, reliable operation and outstanding scalability.
