Patent Images
1. An energy store charging system for use at premises having a mains electricity supply connection, the system comprising:
- a load sensor arranged to determine a total of the concurrent electrical loads on the mains supply at the premises;
a charging circuit electrically connected to the mains supply for delivering power to the energy store, and,a controller arranged to compare the total load to a maximum threshold power supply deliverable for the premises via the mains electrical supply and to limit the power drawn by the charging circuit in dependence upon the result of said comparison.

Abstract
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.

18. A method of charging an electrical vehicle energy store from a mains electricity supply connection, the method comprising:
-
receiving electricity from a mains electricity supply; determining a total of the concurrent electrical loads on the same mains electrical supply; limiting the power drawn by an electric charger for said energy store in dependence upon a comparison between the total load drawn from said mains electrical supply and a maximum power supply deliverable from the mains electrical supply; and
,delivering power to the energy store up to said limit.
