Research on Field Calibration Method Based on Remote Non-Vehicle-Mounted Chargers
In order to improve the field calibration capability of non-vehicle-mounted chargers and the lagging efficiency of calibration in the existing technology,a field calibration method based on remote non-vehicle-mounted charger is designed.The method realizes non-vehicle-mounted charger power metering and detection control through CS5464 non-vehicle-mounted motor power metering chip.In detection and control,voltage and current metering circuits are designed to detect and so on.In electric energy calculation,the calculation and control of data information,such as voltage and current amplitude,waveform,frequency and phase,etc.,are realized through the MSP430FG4619 core microcontroller unit(MCU)chip.These data information multi-angle,multi-faceted to present the information of non-vehicle-mounted charger operating parameters.Through these data information,the field calibration situation can be comprehensively reflected,and the field calibration accuracy of non-vehicle-mounted charger can be improved.Through template calibration algorithm,the high-precision non-vehicle-mounted charger field calibration verification can be realized,the field measurement and verification capability can be improved.The test results shows that the method has low error.The method provides new ideas for the next technical research.
