Based on virtual distributed processing unit (DPU) technology of distributed control system (DCS), a supervisory control system for commercial electric vehicle charging station was designed and exploited. The real time data exchange between charger and virtual DPU of supervisory control system was realized with CAN bus. Virtual DPU configuration function was used to exploit the control logic and monitoring interface. History data was reliably stored utilizing DCS platform. Fully utilizing mature and stable function of historical trend query, sound and light alarm, operation record, statistical report and fault remembrance in DCS, subsystems of charging, metering and billing, power distribution, entrance guard and video guard were totally monitored. The performance of the supervisory control system can accord with the relevant document regulation and requirement of the State Grid Corporation of China (SGCC), which fully satisfy the requirement of commercialization operation.
