To make it easy to determine whether to travel without battery charging or to travel after battery charging, thereby making it more convenient to drive an electric vehicle.

This in-vehicle environment setting system includes an in-vehicle environment setting system 5 and a display unit 6 for displaying setting information from the setting system 5. In the setting system 5, a travelable distance and the degree of necessity of battery charging are calculated based on driver information read from a memory card 9 and on remaining battery charge while the calculated travelable distance and the state of a battery requiring a charge are displayed on the display unit 6.
