Electric and hybrid-electric vehicles equipped with an electric propulsion engine generally include electrical energy storage modules capable of being recharged via an electrical power source external to the vehicle, for example terminals or external charging stations. To do this, the user plugs a plug located at the end of an electrical cable, connected to an external electrical power source, into the charging socket of an electrical charging hatch installed on a bodywork element. of the vehicle.

It is known from American patent application US-A1-20110043355 such a recharging hatch comprising display means provided with a plurality of indicator lights arranged in a circular manner around the charging socket and capable of illuminating in a first color when the cover is moved from its closed position to its open position. These display means are also connected to the vehicle's electrical energy storage modules in order to detect its charge level and inform the user: only certain indicators are illuminated to form an arc of a circle whose length corresponds at this load level.

Although such a solution is widely adopted, it sometimes poses problems with the visibility of the color displayed when the sun illuminates the indicator lights.

This first sound signaling sequence can for example be formed by a particular melody emitted over a period of 30 seconds.

Then, when the electrical energy storage modules are completely recharged, a second predetermined sound signaling sequence different from the first sequence can be emitted. This second sequence can for example be formed by a discontinuous beep. Thus, the user is able to determine the state of charge of the electrical energy storage modules of his vehicle by listening to an audio signaling sequence. It is not dependent on sunshine.

In addition to the characteristics which have just been mentioned in the previous paragraph, the process according to the invention may present one or more complementary characteristics among the following, considered individually or in all technically possible combinations.
