Abstract
A method of oil pre-conditioning for an electric powertrain for a vehicle configured to provide electric propulsion of the vehicle, said electric powertrain comprising the first electric motor being linked to the first gear module, a secondary shaft being linked to the second gear module, the second electric motor being linked to the third gear module through a motor shaft, the differential being shared by both electric motors,The electric powertrain is surrounded by an oil. The method includes the steps of selecting an oil pre-conditioning configuration wherein the secondary shaft does not rotate and at least one of the first electric motor or the second electric motor rotates while the other is in driving mode leading to the heating of the oil to reach a threshold temperature and applying the selected oil pre-conditioning configuration.
