Abstract
Coupling a charging station to a power line segment that is terminated at a first end by a charging terminal includes: sensing a communication signal propagating on the power line and being coupled from multiple taps connected to the power line segment, and determining if the communication signal is propagating on the power line segment in the direction from the first end to a second end of the power line segment or in the direction from the second end to the first end.
Claims31
An apparatus for coupling a charging station to a power line segment that is terminated at a first end by a charging terminal, the apparatus comprising:
- multiple taps coupled to the power line segment;
- and
- circuitry coupled to the charging station and coupled to the multiple taps, with the circuitry being configured to discriminate between communication signals propagating on the power line segment in the direction from the first end to a second end of the power line segment and communication signals propagating on the power line segment in the direction from the second end to the first end.
A method for coupling a charging station to a power line segment that is terminated at a first end by a charging terminal, the method comprising:
- sensing a communication signal propagating on the power line and being coupled from multiple taps connected to the power line segment;
- and
- determining if the communication signal is propagating on the power line segment in the direction from the first end to a second end of the power line segment or in the direction from the second end to the first end.
An apparatus for coupling a charging station to a power line segment that is terminated at a first end by a charging terminal, the apparatus comprising:
- multiple taps coupled to the power line segment;
- and
- circuitry in communication with each of the taps, with the circuitry being configured to control a phase for at least a portion of a signal for at least a first of the taps relative to a phase for a corresponding portion of the signal for at least a second of the taps.
A method, comprising:
- delivering power to a vehicle via a power line segment connected to the vehicle through a charging terminal at a first end of the power line segment;
- receiving a first communication signal including billing information from the vehicle that is propagating on the power line segment in the direction from the first end;
- and
- discriminating between the first communication signal and a second communication signal including billing information that is propagating on the power line segment in the direction from a second end of the power line segment not connected to the vehicle to the first end;
- wherein discriminating between the first and second communication signals comprises determining in which direction on the power line segment a sensed communication signal is propagating.
