A system for the distribution of electricity to electric vehicles (EVs) 121-132 receiving charge from domestic supplies includes a grid-connected source of electrical energy 117, a plurality of dwellings 101-116, a power manager 118, a plurality of battery chargers and a plurality of control units. The grid-connected source supplies electrical energy to the dwellings within predetermined constraints of an individual maximum power level to each dwelling and a total maximum power level. The battery chargers charge respective EVs from a respective domestic supply. Each control unit is positioned between a domestic supply and a respective battery charger and selectively connects the respective battery charger to the respective domestic supply in response to power management commands from the power manager. The power management commands may be: time-based and identify intervals when an EV may be charged and intervals when the EV cannot be charged; or derived from an assessment of actual demand, determined by measuring the total energy being used to charge EVs from the grid-connected source. Each control unit has a switching device that selectively connects the domestic supply to an electric outlet for the battery charger in response to a determination whether the electrical outlet can be activated to supply electricity to the battery charger.
