Electric vehicle charging dispenser and method

A charging dispenser, comprising:

• a dispenser input including:
• a direct current (DC) electrical power input,
• a control signal input, and
• a controller power input;
• a DC electrical power pass through power output;
• a dispenser DC electrical power output;
• a switching unit coupled between the DC electrical power input and the DC electrical power pass through output and the dispenser DC electrical power output;
• and
• a controller coupled to the control signal input and coupled to the controller power input, the controller configured to receive control signals from the control signal input from a master controller of a charging power cabinet,
• wherein the DC electrical power pass through power output is configured to connect the DC electrical power input of the charging dispenser with a DC electrical power input of another charging dispenser coupled to the charging dispenser in series in a chain of charging dispensers and route DC electrical power from a DC power module coupled to the chain of charging dispensers to the another charging dispenser through the charging dispenser.

A method of providing charging power to a vehicle, the method comprising:

• receiving, by a controller, control signals from a master controller of a charging power cabinet;
• supplying direct current (DC) electrical power to a DC electrical power input of a charging dispenser;
• responsive to the control signals, electrically disconnecting the DC electrical power input of the charging dispenser from a DC electrical power pass through output of the charging dispenser;
• responsive to the control signals, electrically connecting the DC electrical power input of the charging dispenser to a DC electrical power charging output of the charging dispenser;
• providing the DC electrical power to the vehicle through the DC electrical power charging output;
• responsive to the control signals, electrically disconnecting the DC electrical power input of the charging dispenser from the DC electrical power charging output of the charging dispenser;
• responsive to the control signals, electrically connecting the DC electrical power input of the charging dispenser to the DC electrical power pass through output of the charging dispenser;
• and
• providing the DC electrical power to another charging dispenser coupled to the charging dispenser in series in a chain of charging dispensers through the DC electrical power pass through output of the charging dispenser and routing the DC electrical power from a DC power module coupled to the chain of charging dispensers to the another charging dispenser through the charging dispenser.
