METHOD FOR CONTROLLING AN ELECTRIC TRACTION SYSTEM AND CORRESPONDING ELECTRIC TRACTION SYSTEM

摘要

It relates to an electric traction system and a control method for controlling the corresponding electric traction system. The present invention relates to a method for controlling an electric traction system including an electric drive motor, a drive battery, and a drive inverter, the method comprising:-a measured value of insulation resistance between a chassis of a vehicle and a drive battery is greater than a predetermined threshold. Detecting a low level (E1),-detecting a closed state of the relay (E2) connecting the drive battery to the drive inverter, and detecting the first (E1, E2) following the predetermined first It is characterized in that, within the limits of the periods T1 and T2, the steps E4 and E8 of operating the cooling fan of the motor are performed until the insulation resistance Ri becomes greater than the predetermined threshold. .
