Abstract
A charging system for electric vehicles is disclosed, which includes at least one charging port with an interface for power exchange with at least one electric vehicle, and at least one power converter for converting power from a power source such as a power grid to a suitable format for charging the vehicle. The power converter can be at a remote location from the charging port, such as a separate room, and/or a separate building.
Claims20
A charging system for electric vehicles, comprising:
- a plurality of charging ports, each with an interface for power exchange with at least one electric vehicle;
- a plurality of power converters for converting power from a power source to a desired format for charging the at least one electric vehicle;
- a switchable connection matrix for connecting at least one of the plurality of power converters to at least one of the plurality of charging ports;
- wherein the switchable connection matrix comprises a grid of switches with a first number of the switches equal to a number of the plurality of charging ports and a second number of the switches equal to a number of the plurality of power converters, the switchable connection matrix comprising a number of the switches equal to the first number times the second number;
- wherein each of the plurality of power converters is connected to one set of the first number of the switches connected to each other in series;
- and
- wherein each of the plurality of charging ports is connected to one set of the second number of the switches connected to each other in series.
