An electric power metering device which includes a current sensor, an electronic measurement and rectifier circuit, a processing circuit and a transmitter connected to the processing circuit to transmit power messages to an electric power measurement receiver. An electric current integration capacitor is connected to the current sensor via a rectifier circuit. A switch is commanded by a threshold detector to supply to the processing circuit and the transmitter power accumulated in the capacitor when its electric voltage has exceeded a predefined voltage threshold. A power message representative of a quantity of electric power is then transmitted. A power metering method includes transmission of a power message when a capacitor voltage has reached a voltage threshold.

Electric power metering device and method

A method for distributing electricity is used in a system including a three-phase current distribution network, recharge terminals for electric vehicles connected to the distribution network via three phase conductors and one neutral conductor, electric vehicles equipped with a storage battery, means for measuring electric currents and voltages in the system, and a monitoring device for communicating with the electric vehicles and the measuring means. The distribution network supplies or receives electricity at the recharge terminals, and electric vehicles are recharged or discharged on these terminals via a single-phase or three-phase electric link. The method includes identifying an arrival of an electric vehicle at a recharge terminal, identifying energy requirements of the electric vehicle, assigning at least one electric current phase carried by one of the three phase conductors to the recharge terminal, and transferring energy to or from the storage battery (or batteries) of the electric vehicle.
