A charging system (100, 300) including a plurality of charging devices (104, 304, 306, 308),, the system (100, 300) comprising: a current control device configured to selectively enable current to be received by a first charging device from the plurality of charging devices (104, 304, 306, 308) from an electric power source and supplied from the first charging device to a power storage device; a network interface configured to couple to at least one other charging device (304, 306, 308) to form a network; and a processor coupled to said current control device and programmed to: transmit a first request to said at least one other charging device (304, 306, 308) to determine an amount of current that said at least one other charging device (304, 306, 308) is at least one of supplying, receiving, expecting to receive, and expecting to supply; determine an amount of current to be at least one of received from the electric power source and supplied to the power storage device as a function of a number of charging devices (104, 304, 306, 308) within the network; control said current control device to enable the amount of current to be at least one of received from the electric power source and supplied to the power storage device; wherein, in response to the first request, the processor is programmed to receive current usage data to be received from said at least one other charging device (304, 306, 308), characterised in that said processor is further programmed to detect an interference that occurs when a second charging device transmits a current usage request while said first charging device is waiting to receive current supply data from at least one other charging device (304, 306, 308) in the network in response to the first current usage request, and when an interference of current usage requests occurs, the charging device (104, 304, 306, 308) that detects the interference transmits an interference message to all other charging devices (104 304, 306, 308) within the network. a current control device configured to selectively enable current to be received by a first charging device from the plurality of charging devices (104, 304, 306, 308) from an electric power source and supplied from the first charging device to a power storage device;
