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.
