An electric power train for an automotive vehicle includes an electric motor, a power electronics system, a first casing containing the power electronics system, a second distinct casing that contains the motor, and a third distinct casing. The first casing includes a bottom and an opening for access to the power electronics system. The second casing bears on an exterior wall of the first casing bottom. The opening is opposite the second casing. The third casing is assembled on the first casing and contains an electric filtering system. The first casing includes a platform, which juts out relative to at least one portion of the first casing and on a face of which platform an assembly contour for assembling the third casing on the first casing is defined. The assembly contour is substantially parallel to an axial direction of the motor. The platform overhangs the second casing.
