Abstract

One or more examples provide an electric vehicle or a device for use with an electric vehicle, including an electric vehicle charging system and method. In one example, an electric vehicle charging system with a charging robot rail switch is disclosed.

Claims (43)

1 . An electric vehicle charging system comprising:

a charging bus including multiple power drops, where each power drop is associated with a charging location;

a charging robot that aids in completing a charging connection between a power drop and the electric vehicle at the charging location;

a charging robot track system configured to allow the charging robot to move between the multiple power drops;

the charging robot track system including a rail extending along the charging bus, where the charging robot is movably coupled to the rail for moving along the charging robot track system;

a rail switch coupled to the rail that moves the charging robot from the rail to a location off the rail;

a rail spur coupled to the rail switch; and

where the rail switch moves the charging robot from the rail to the rail spur.

2 . The electric vehicle charging system of claim 1 , comprising:

a docking station, where the rail spur is coupled between the rail and the docking station.

3 . The electric vehicle charging system of claim 2 , comprising:

a first power drop coupled to the charging bus, where the docking station is located along the first power drop.

4 . An electric vehicle charging system comprising:

a charging bus having multiple power drops, including a first power drop that couples a charging bus to a first charging location;

a first charging robot that aids in completing a charging connection between a the first power drop and the first charging location; and

a rail configured to allow the first charging robot to move along the charging bus;

a rail switch located along the rail; and

a spur, where the rail switch is configured to move the first charging robot between a first position on the rail and a second position off the rail on the spur.

5 . The electric vehicle charging system of claim 4 , comprising:

a docking station, where the spur is coupled between the rail switch and the docking station, and where in the second position the charging robot is positioned at the docking station.

6 . The electric vehicle charging system of claim 5 , comprising:

where the docking station is positioned along the first power drop.

7 . The electric vehicle charging system of claim 6 , where when the first charging robot is positioned on the docking station the first charging robot is controllable to connect a charging circuit between the charging bus and the first charging location.

8 . The electric vehicle charging system of claim 4 , where the rail switch comprises:

a switch mechanism including a switch first position where the switch mechanism is in alignment with the rail and a switch second position where the switch mechanism is in alignment with the spur.

9 . The electric vehicle charging system of claim 8 , the rail switch comprising an electric motor for moving the switch mechanism between the switch first position and the switch second position.

10 . The electric vehicle charging system of claim 4 , comprising:

a charging bus support structure that supports the charging bus; and

where the charging bus support structure also supports the rail.

11 . The electric vehicle charging system of claim 4 , comprising:

a second charging robot movably coupled to the rail.

12 . An electric vehicle charging system comprising:

a charging bus having multiple power drops, including a first power drop that couples a charging bus to a first charging location and a second power drop that couples the charging bus to a second charging location;

a track system that allows a first charging robot and a second charging robot to move along the charging bus, including between the first power drop and the second power drop; and

the track system comprising a first rail switch and a first spur coupled to the first rail switch; and a second rail switch and a second spur coupled to the second rail switch.

13 . The electric vehicle charging system of claim 12 , comprising:

a bus support structure, where the charging bus and the track system are supported by the same bus support structure.

14 . The electric vehicle charging system of claim 12 , comprising:

the first rail switch having a first rail switch first position where the first rail switch is in alignment with the rail and a first rail switch second position where the first switch is in alignment with the first spur; and

the second rail switch having a second rail switch first position where the second rail switch is in alignment with the rail and a second rail switch second position where the second rail switch is in alignment with the second spur.

15 . The electric vehicle charging system of claim 14 , comprising:

a first docking station positioned on the first power drop, where the first docking station is coupled to the first spur; and

a second docking station positioned on the second power drop, where the second docking station is coupled to the second spur.
