Abstract

An electric drive system (1) comprises an electric motor (10), a transmission (20), and a bottom oil passage (40). The electric motor (10) comprises an electric motor housing (11). The electric motor housing (11)comprises an electric motor cavity (11A) and oil inlets (20). The transmission is in power connection with the electric motor (10). The transmission comprises a transmission housing (21), the transmission housing (21) comprises a transmission cavity (21C) and oil outlets. The bottom oil passage (40) is in communication with the electric motor cavity (11A)and the transmission cavity (21C). When the electric drive system (1) is in a horizontal state, heights of all the oil inlets are not lower than that of any oil outlet, and the oil inlets connected to the bottom oil passage (40) are arranged circumferentially at a bottom of the electric motor housing (11), to enable an oil in the electric motor cavity (11A)to flow back into the transmission cavity (21C) in a first preset gradient state of the electric drive system (1), ensuring an appropriate level of oil within the electric drive system.
