Patent number: 9225564Abstract: 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.Type: GrantFiled: June 21, 2012Date of Patent: December 29, 2015Assignee: Mitsubishi Electric CorporationInventors: Yuji Igarashi, Takashi Tamada, Yoshitsugu Sawa, Kazushi Shirasawa, Takanori Matsunaga, Hiroyuki Kumazawa

Patent number: 9184792Abstract: In a charging communication system in which a charging control device performs communication between an electric vehicle and a charging equipment, the electric vehicle is equipped with a first communication device and a second communication device both configured to communicate with the charging equipment by using the same signal line in the charging cable; and a signal line connection device configured to switch connection/disconnection between the second communication device and the signal line. The charging control device, which controls a battery on the electric vehicle, calculates an amount of change in a signal line voltage between before and after the signal line connection device connects the second communication device to the signal line, and the charging control device causes, when the amount of change does not fall within a predetermined allowable range, the signal line connection device to disconnect the second communication device from the signal line.Type: GrantFiled: April 1, 2013Date of Patent: November 10, 2015Assignee: Mitsubishi Electric CorporationInventors: Yuji Igarashi, Takashi Tamada, Yoichi Okubo, Takanori Matsunaga, Kazushi Shirasawa, Hiroyuki Kumazawa
