1. An electric vehicle comprising:
- an electric motor for driving a wheel;
an inverter that supplies electric power to the electric motor; and
a cooling system that cools at least one of the electric motor and the inverter, the cooling system including;
a main coolant passage configured to circulate a coolant through a radiator and at least one of the electric motor and the inverter;
a bypass coolant passage that is connected to the main coolant passage and that bypasses at least one of the electric motor and the inverter; and
a controller configured to switch from the main coolant passage to the bypass coolant passage when an ignition switch of the vehicle, that is provided at a driver'"'"'s seat, is switched from an on-state to an off-state while the electric vehicle is travelling, and to switch from the bypass coolant passage to the main coolant passage when the ignition switch is switched back to the on-state.
