An energy store charging system is provided for an electric vehicle for use typically in premises having a mains electrical supply. The system includes a load sensor arranged to determine the total concurrent electrical loads on the same mains electrical supply circuit and a charging circuit connected to said mains supply for delivering power to the energy store. A controller is arranged to limit the power drawn by the charging circuit in dependence upon a comparison between the total concurrent electrical load and a maximum threshold power supply deliverable via the incoming mains electrical supply line.
