ELECTRIC POWER SUPPLY MONITORING PROCESS AND SYSTEM FOR AN ELECTRIC TRACTION VEHICLE DESIGNED TO OPERATE IN EXTERNAL POWER SUPPLY MODE OR SELF SUPPLY MODE

摘要

The invention relates to a method for controlling the electric power supply of an electric traction vehicle intended to operate in an external power supply mode or in an autonomous power supply mode, said vehicle comprising a continuous power supply bus (1 ) connected to both an autonomous power supply system (6) on board the vehicle and to an external power supply line (2) connectable to an external power supply infrastructure (7) by means of an external power supply connection connector (5), characterized in that the connection of said connection member (5) is detected with said external power supply infrastructure (7) by measuring the current flowing through the external power supply line (2), the presence of a non-zero current in the line (2) signaling the presence of an external power supply infrastructure (7) connected to said connection member (5).
