The charging of electric vehicles (121, 122) from a domestic electricity supply (117) is shown, in which a grid-connected source (117) supplies electricity to a plurality of dwellings (102, 103), with each dwelling having a charging outlet for charging an electric vehicle. A power management apparatus (201) is provided along with control units (211, 212). The power management apparatus establishes a weekly schedule (603, 604) for each dwelling, consisting of contiguous intervals (801) of less than one hour during which a respective control unit may permit the charging of an electric vehicle or is forced to inhibit the charging of the electric vehicle. The power management apparatus transmits respective schedule data, derived from an established weekly schedule, to each dwelling. Each control unit (211) is connected between the grid connected source (117) and a respective one of the charging outlets (1001). Each control unit receives the schedule data and stores this schedule data to re-establish a local copy of the weekly schedule for the respective dwelling, with any previously stored schedule being replaced. Thereafter, the control unit operates switches (1111, 1112, 1113) to permit the charging of an electric vehicle or inhibit the charging of the electric vehicle in accordance with the respective locally stored weekly schedule.
