System and method for charging motor vehicles

A method for charging electrical devices with electrical energy wherein, having:

• at least a first charger and a second charger, each charger being adapted to supply instantaneous electrical energy for charging an electric vehicle, said electrical energies having different electrical charging characteristics, wherein said electrical charging characteristics is the set of admissible operating points in terms of electrical voltage and electrical current which can be produced by the respective charger,
• a first electrical line adapted to connect the first charger to an electric vehicle located at any location;
• a second electrical line adapted to connect the second charger to an electric vehicle located at any location,
• a switching system adapted to alternatively connect or not connect the electric vehicles to the first charger or to the second charger, the switching system comprising a switching device respectively associated with a charging cable for each location for charging an electrical device, each switching device being able to alternatively:
• electrically connect the charging cable for the location associated with the switching device to the first charger,
• electrically connect the charging cable for the location associated with the switching device to the second charger,
• electrically disconnect the charging cable for the location from any charger and from any other charging cable for any other location,
• the switching system being adapted to prohibit several chargers from being connected simultaneously to the same charging terminal,
• the switching system being adapted to prohibit any charger from being connected simultaneously to a plurality of charging terminals;
• a computerized reception module of a control system receives electrical charge demand information from electric vehicles;
• a processor of the control system repeatedly determines a map of connections between the electric vehicles and the chargers as a function at least of the received electrical charge demand information and of the said electric charging characteristics, and
• the control system (8) repeatedly controls the switching system to electrically connect one of the electric vehicles to the first charger and another of the electric devices to the second charger.
