On-board power line communication system

摘要

An on-board power line communication system that performs power line communication during charging and discharging of a battery prevents electromagnetic wave leakage from a power line from interfering with other on-board devices. A vehicle includes a PLC communication device that performs PLC communication using a charging cable that is connected to a battery, and an interference suppressor that prevents electromagnetic wave leakage from the charging cable, which accompanies PLC communication, from interfering with the operations of an on-board electronic device. The interference suppressor reduces electromagnetic wave leakage from the charging cable by reducing the output frequency of the PLC communication device or the value of current flowing through the charging cable while the on-board electronic device is performing a specific operation that will be affected by interference from PLC communication.

主权项

1. An on-board power line communication system comprising:
a power line communication device that performs communication using a power line that is connected to an on-board battery; and an interference suppressor that, upon detecting that an on-board electronic device is to perform a specific operation, controls at least one of an output of said power line communication device and a value of current flowing through said power line during the specific operation to reduce electromagnetic wave leakage from said power line.
