The invention provides an electric drive system. The electric drive system comprises a motor, a gearbox and a bottom oil way. The motor comprises a motor shell, and the motor shell is provided with a motor cavity and an oil inlet; the gearbox is in power connection with the motor and comprises a gearbox body, and the gearbox body is provided with a gearbox cavity and an oil outlet; the bottom oil way is communicated with the motor cavity and the gearbox cavity. When the electric driving system is in a horizontal state, the heights of all the oil inlets are not lower than the height of any oil outlet, and the oil inlets connected with the bottom oil way are formed in the bottom of the motor shell in the circumferential direction, so that when the electric driving system is in a first preset slope state, the oil inlets connected with the bottom oil way are not lower than any oil outlet. And oil in the motor cavity can flow back into the gearbox cavity, so that a proper oil liquid level exists in the electric driving system. The invention further provides an electric drive vehicle which is provided with the electric drive system and can adapt to road surfaces with different gradients.
