A power transmission system includes: a power source; a speed change unit, where the speed change unit is suitable for being selectively power-coupled to the power source; a first motor generator unit; a system power output portion; a first mode conversion device, where at least one of the speed change unit and the first motor generator unit is power-coupled to or power-decoupled from the system power output portion through the first mode conversion device; and a second mode conversion device, where the speed change unit can be power-coupled to or power-decoupled from the first mode conversion device through the second mode conversion device, and the speed change unit can be power-coupled to the first mode conversion device through the second mode conversion device, so that power from the power source is decelerated sequentially through the speed change unit and the second mode conversion device and then output to the first mode conversion device.
