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 two stage DC charging is disclosed. The charging system can include a charging robot.
Claims20
An electric vehicle charging system comprising:
- a first converter that converts an input voltage to an intermediate DC charging voltage;
- an intermediate DC charging bus coupled to the first converter where the intermediate charging voltage is provided to the intermediate DC charging bus;
- and
- a switching system coupled to the intermediate DC charging bus, where the switching system is associated with a vehicle charging location, the switching system including a second converter located between the intermediate DC charging bus and the vehicle location that converts the intermediate DC charging voltage to a DC charging voltage of a vehicle requesting a charge.

An electric vehicle charging system including a 2 stage charging system comprising:
- a first stage that converts an input charging voltage to an intermediate level DC charging voltage;
- an intermediate charging bus coupled to the first stage;
- a charging robot positionable between the intermediate charging bus and a charging location, the charging robot including a second stage that converts the intermediate level DC charging voltage to an electric vehicle target voltage.
An electric vehicle charging system comprising:
- an AC power bus;
- a first converter coupled to the AC power bus that converts an AC input voltage to an intermediate DC charging voltage;
- an intermediate DC charging bus coupled to the first converter;
- and
- a switching system coupled to the intermediate DC charging bus, where the switching system is associated with a vehicle charging location, the switching system including a second converter that converts the intermediate DC charging voltage to a DC charging voltage of a vehicle requesting a charge.
