The invention relates to a transmission system for an electric vehicle. The transmission system comprises an electric motor, an inverter, a speed reducer and a cooling circuit. The electric motor, the inverter and the speed reducer are integrated to form a transmission system assembly, and the cooling circuit is used for enabling a coolant to flow through the cooling circuit and distributing the coolant into the transmission system assembly. The cooling circuit includes a cooling channel located inside the inverter, the cooling channel including a coolant retention portion for retaining coolant from the cooling circuit therein, an inlet to receive the coolant, and an outlet to discharge the coolant. The application also relates to a method of cooling a driveline for an electric vehicle.
