Abstract

Provided is an electric bus and an electric bus battery exchange system. The electric bus according to the present invention includes: a battery exchange hole disposed on top of the electric bus for exchanging a discharged battery for a charged battery; a front camera unit taking front images in the process of entering the battery exchange station for battery exchange; a communication unit for receiving position information of the battery exchange unit from the battery exchange station; a route output unit outputting a predicted driving route for reaching a swapping point below the battery exchange unit based on the front images taken by the front camera unit and the position information of the battery exchange unit; and a display unit displaying the predicted driving route outputted by the route output unit, superimposed on the front images taken by the front camera unit.

Claims

1. An electric bus comprising:

a battery exchange hole disposed on top of the electric bus for exchanging a discharged battery for a charged battery by being connected to a battery exchange unit of a battery exchange station;

a front camera unit taking front images in the process of entering the battery exchange station for battery exchange;

a communication unit for receiving position information of the battery exchange unit from the battery exchange station;

a route output unit outputting a predicted driving route for reaching a swapping point below the battery exchange unit based on the front images taken by the front camera unit and the position information of the battery exchange unit; and

a display unit displaying the predicted driving route outputted by the route output unit, superimposed on the front images taken by the front camera unit, wherein the front camera unit takes front images when a reservation of battery exchange exists.
