Abstract: A charging device for electric vehicles includes two power sources interacting with a primary inductive device. The charging device also includes an input circuit having a first input connectable to a first power source, a second input and at least one output connectable to a charger, a secondary inductive device capable of being coupled to the primary inductive device for energy transfer between the primary inductive device and the secondary inductive device, thereby generating an induced electric signal at the output of the secondary inductive device, and a converter from the induced electric signal to an electric signal towards the second power supply input of the input circuit, the converter being configured such that the electric signal is similar to the electric signal of the first power source.

Abstract: The invention relates to a method for managing the heating of water in a tank of a water heater which comprises a device for electrically heating the water in the tank, characterized in that it comprises, when a water heating phase is actuated: activation of heating by the heating device, determination of a variation of the temperature in the tank over time and determination of at least one water filling state in the tank according to the variation over time.

Abstract: The present invention relates to an assembly formed by a water heater comprising a heating body comprising a volume of water and at least one power generator of an inductive device dedicated to an electrical appliance. The assembly comprises a heat exchanger between said at least one power generator and an area through which water travels towards or into the heating body of the water heater. Application in the field of domestic electrical appliances, in particular water heaters.
