In this paper, an Electric Vehicle (EV) charging system, which is jointly designed by the research center and local power-distribution company, would be presented. The system consists of a number of Charging Points (CPs), a control unit, a user-interface and an electronic payment mechanism. The CPs are gridconnected and allow power electronics connections for Battery Charging. Power supplies are controlled and monitored simultaneously by the control unit. Meanwhile, the charging system provides a userinterface that allows customers to select the desired charging time and read the charging status. The CPs are connected to the charging system via Ethernet thus the number of CPs could easily be extended once the power distribution line is established and CPs is connected to the grid. Electrical parameters, such as line voltage, current, power factor, etc. could be also acquired via Ethernet. The prototype was later developed into a commercial product with an electronic payment mechanism implemented and has been opened to public use for months.
