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.
Claims8
An on-board device for an electric vehicle equipped with an electrical energy collector, wherein the electrical energy collector is an electrical energy storage, the on-board device being electrically connected to a first terminal and a second terminal of the electrical energy collector and being provided with a first electrical contact and a second electrical contact to provide electrical power path connections for supplying electricity to the electrical energy collector respectively with a first conjugated electrical contact and a second conjugated electrical contact of a supply device, the supply device being electrically connected to an electrical power source from a recharging station,
- the on-board device having 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 electrical energy collector, the diode is for avoiding a circulation of a current toward the second terminal of the electrical energy collector through the mesh,
- wherein the mesh also includes a connecting node for the connection to a body of the electric vehicle and the diode is inserted between the connecting node and the second terminal.
