Abstract

An apparatus includes multiple taps coupled to a power line segment. The apparatus also includes circuitry coupled to a charging station and coupled to the multiple taps, with the circuitry being configured to discriminate between communication signals propagating on a 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. The circuitry includes a signal processing unit in communication with each of the taps, wherein the signal processing unit is 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.

Claims

1. 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.
