Method of and a system for controlling the supply of electrical power to an electrically propelled vehicle designed to operate in an external power supply mode or in an autonomous power supply mode
First Claim
1. A method of controlling the supply of electrical power to an electrically propelled vehicle designed to operate in an external power supply mode or in an autonomous power supply mode as a function of the presence or the absence of the external power supply infrastructure along the route of said vehicle, which includes an uninterrupted power supply bus connected both to an autonomous power supply system on board said vehicle and to an external power supply line that can be connected to an external power supply infrastructure by means of a connection member, in which method connection of said connection member to said external power supply infrastructure is detected by measuring the current flowing in said external power supply line, the presence of a non-zero current in said line indicating the presence of an external power supply infrastructure connected to said connection member.

Abstract
A method is disclosed of controlling the supply of electrical power to an electrically propelled vehicle designed to operate in an external power supply mode or in an autonomous power supply mode. The vehicle includes an uninterrupted power supply bus connected both to an autonomous power supply system on board the vehicle and to an external power supply line which can be connected to an external power supply infrastructure by means of a connection member. Connection of the connection member to the external power supply infrastructure is detected by measuring the current flowing in the external power supply line. The presence of a non-zero current in the line indicates the presence of an external power supply infrastructure connected to the connection member.
