Abstract
An electric motorcycle is provided that can air-cool a power drive unit without the provision of a plurality of cooling fans. In an electric vehicle in which a battery box housing batteries is disposed below a foot rest space and electricity supplied from the batteries is supplied to a running-purpose power-generating motor via a power drive unit, the power drive unit is attached to a swing arm turning around a pivot shaft and the battery box is formed with an air introduction port and an air discharge port used to cool the batteries. A cooling fan is provided which sucks air in the battery box from the air discharge port and sends the air toward the power drive unit. The cooling fan is disposed rearward of the air discharge port of the battery box and close to the pivot shaft.
