Electric vehicle driving device

Abstract

This electric vehicle driving device includes: a motor; a gear box storing a speed reduction mechanism connected to the motor, and a differential mechanism connected to the speed reduction mechanism; an inverter which is electrically connected to the motor and converts power; and an oil cooler which oil-cools the motor. The inverter has first and second cooling water paths through which cooling water flows. The oil cooler has an oil-cooler water path through which the cooling water flows. The oil cooler is provided in contact with the inverter. At the contact part, the first cooling water path and the oil-cooler water path are connected, and the second cooling water path and the oil-cooler water path are connected. A water path is formed such that the cooling water flows in order of the first cooling water path, the oil-cooler water path, and then the second cooling water path.
