A centralized charging system for electric vehicles includes an electrical distribution arrangement 10 connected between at least one power source 12-14 and a plurality of charging stations 30, 40, 50, 60. Each charging station is on an individual charging circuit 17-20 and may charge more than one vehicle 100-107. Each circuit comprises a high-amperage electrical line and charging point with an electrical plug. The electrical distribution arrangement comprises a plurality of switch modules and a local processing module. Each switch module is connected to a charging circuit and includes a switch, a current sensor and an analogue circuit connected to the switch and producing a signal based on the current sensor measurement. The local processing module includes a processor configured to read the signal and control a display connected to the processor. The display shows the charging status of each charging session, including charge time, on/ff status and fault status. A metering unit is connected to the power source and a control mechanism is provided to control a parameter such as charging time or on/off status. A central processor or controller 500 may be provided to communicate with the local processor via a cellular network 275 and the internet 250. |
