Matrix switches for optimizing resource utilization in large-scale charging stations with distributed energy resources

A DC matrix power switch (m×n matrix) structure that electrically connects m DC power modules to n charge dispensers for charging electric vehicles comprising:

• an input structure having m conducting input busbar pairs;
• wherein the first busbar of each of said m input busbar pairs is connected to the positive voltage terminal of each of m DC power modules;
• wherein the second busbar of said m input busbar pairs is connected to the negative voltage terminal of each of said m DC power modules;
• an output structure having n conducting output busbar pairs;
• wherein the first busbar of each of said n output busbar pairs is connected to the positive voltage terminal of each of said n charge dispensers;
• wherein the second busbar of each of said n output busbar pairs is connected to the negative voltage terminal of each of said n charge dispensers;
• wherein the input structure and the output structure are arranged to form m×n crossing busbar pairs corresponding to two times m×n busbar crossing points (nodes);
• respective power switches mechanically mounted to the matrix power switch structure at each of two times m×n the busbar crossing points (nodes);
• a communication link for at least control signals to activate or deactivate each power switch;
• wherein when activated, the power switch electrically connects to the associated busbar at the busbar crossing point (node);
• connections are made between the busbar pairs so that there is current flow from positive to negative;
• when DC power is removed from the respective power switch, or the respective power switch receives a command to deactivate, the connection between the associated input and output busbars is terminated.
