Abstract: A device is electrically connected to first and second terminals of an energy collector and provided with first and second electrical contacts intended to be placed in contact, for the electrical supply of the energy collector, respectively with first and second conjugated electrical contacts of a supply device on the ground, in turn electrically connected to an electrical power source. The device has a mesh connecting the second electrical contact and an output terminal connected to the second terminal of the energy collector, the mesh having a diode inserted between the second electrical contact and the second terminal of the energy collector so as to avoid the circulation of a current toward the second terminal of the energy collector.

Abstract: An installation for recharging an energy storage means, such as a battery of an electric vehicle, by conduction of energy from an electric power source to the energy storage means, where the battery is electrically connected to an on-board device and provided with a plurality of electric contacts, and on the ground, a ground device, combined with the on-board device, is connected to the electric power source and includes a plurality of electric contacts, each electric contact of the ground device being able to be put into contact with a corresponding contact of the on-board device, and the installation being able to safely apply an electric recharging power issued by the electric power source to the battery, where the plurality of electric contacts of the on-board device and of the ground device exclusively includes a phase contact and neutral contact.

Abstract: This installation includes, on-board the vehicle (12) equipped with a battery (30), an on-board device (20), electrically connected to the battery (30) and provided with a plurality of electric contacts, and on the ground, a ground device (40), combined with the on-board device (20), connected to an electric power source (50) and including a plurality of electric contacts, each electric contact of the ground device (40) being able to be put into contact with a corresponding contact of the on-board device (20) and the installation being able to apply, safely, an electric recharging power issued by the electric power source (50) to the battery (30). This installation is characterized in that the plurality of electric contacts of the on-board device (20) and of the ground device (40) exclusively includes two electric contacts, i.e. a phase contact (21; 41) and neutral contact (22; 42).
