Summary: | A method discharges the electrical circuit of a vehicle including at least one traction electric machine and equipped with an electrical supply network including a high-voltage battery and a hydrogen-fuel-cell stack that is associated with a voltage converter, with a high-voltage consumption network including the machine associated with an inverter and appended pieces of equipment, and with a drive module. The discharging method includes the following successive steps: stopping the vehicle, electrically disconnecting the battery from the network, interrupting the supply of hydrogen to the stack, and discharging energy from the electrical circuit into the stator winding of the machine by driving the voltage converter via the drive module. |
