Abstract
A thermal management system for an electric drive module (EDM) in an electric vehicle is provided. The system includes a motor housing, a gearbox housing, a sump and a baffle. The motor housing has an electric motor. The gearbox housing houses gears that receive an input from the electric motor and transfer the drive torque to the driveline. The sump collectively comprises a first sump and a second sump. The first sump is defined by first walls of the motor housing. The second sump is defined by second walls of the gearbox housing. The baffle is disposed in the sump. Rotation of a transfer gear causes oil disposed in the second sump to be urged from the second sump, along the baffle and to the first sump effectively reducing an oil level in the gearbox housing and thereby reducing drag losses in the gearbox housing.
