METHOD AND DEVICE FOR CONTROLLING THE ENERGY SUPPLY OF AN ELECTRICALLY DRIVEN VEHICLE FOR OPERATION IN EXTERNAL POWER SUPPLY MODE OR IN AUTONOMOUS POWER SUPPLY MODE

摘要

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