Design of monitoring system for electric vehicle charging station based on LabVIEW and STM32

Abstract Charging-station provides power supply for electric vehicles, which is a necessary and important energy supporting infrastructure for development and large scale commercialization operation of electric.For the current charging-station management is overly dependent on high-cost devices such as industrial computer, this paper develops a charger field test device, which adopts STM32 as the data exchange interface between the host computer and charger. The charge data is sent to PC through STM32, and the monitoring system development is designed by LABVIEW.This method optimizes the decoding of message content, overcomes the defect of over reliance on high cost components, and strengthenes the ability of bottom message collection, enhances the system intelligence.The communication is fast, reliable and has a good man-machine interface.
