The charging of electric vehicles (EVs) is managed by identifying a maximum level of power available at a charging station. Requests are received for charging power from vehicles connected to respective supply equipment at a notional charging power that represents the highest power level that the vehicle can receive. Power is selectively supplied to supply equipment (e.g. electric vehicle supply equipment, EVSE) and data of actual charging power supplied by a supply device is received by an energy management system. A record of the notional charging power is then modified to a value closer to the actual charging power. Each supply device may include: a recording device for recording a notional charging power; a power measuring device for measuring actual charging power; and an output device for supplying the data of actual charging power to the energy management system. The actual charging power values may be summed to determine a total power output. By comparing the sum of the actual charging power values, rather than the sum of the notional charging power values, against the maximum level of power available, additional vehicles may receive charge without exceeding the maximum power available.
