Abstract :
An online monitoring, analysis, and evaluation system of electric vehicle (EV) charging station is designed and developed. The system structure is based on PCI bus with multi-DSP design, and its hardware consists of multi-DSP acquisition terminal, vehicular terminal, Industrial PC (IPC), FPGA and PCI interface. The voltage and current of the point of common coupling (PCC) of charging station and chargers are collected on real time, and the power quality is calculated based on these data. All monitoring data, which is gathered by PCI bus, is used to analyze the operation characteristic of the transformer and chargers as well as the harmonics and inter-harmonics in the charging station. The start charging time, initial charging state and daily mileage of EVs are statistical on basis of operation and charging information, which are sent to the system via GPRS.
