Description
本発明の第2の局面に係る車載電力線通信システムは、車載バッテリに接続される電力線を用いた通信を行う電力線通信装置と、車載電子機器が特定の双方向通信を行うことを事前に検知し、当該特定の双方向通信が行われる間、前記電力線からの漏洩電磁波を抑制するように前記電力線通信装置の出力および前記電力線を流れる電流値の少なくとも片方を制御する干渉抑制装置とを備え、前記車載バッテリを搭載する車両には、前記電力線を通して前記車両へ電力を供給する給電処理を行う電力供給装置が接続され、前記干渉抑制装置は、前記特定の双方向通信が行われる間、前記電力供給装置による前記給電処理を停止させるものである。
図1は、本実施の形態に係るバッテリ充電システムの構成を示す図である。当該バッテリ充電システムにおいて、車両1は電気自動車であり、バッテリ10、充電制御装置11、PLC通信装置12および干渉抑制装置13を備える。バッテリ10の充電時には、車両1は、充電ケーブル3を介して電力供給装置4に接続される。
上記のように、実施の形態1のバッテリ充電システムでは、車載電子機器14がPLC通信の干渉を受ける動作を行う間PLC通信を停止させていることにより、車載電子機器14の動作にPLC通信が干渉することを防止していた。
図8は、実施の形態3に係るPLC通信装置および干渉抑制装置の構成を示すブロック図である。本実施の形態では、干渉抑制装置13のPLC通信停止部13aに代えて、漏洩電磁波抑制部13dを設けたものである。
実施の形態1のバッテリ充電システムでは、車載電子機器14がPLC通信の干渉を受ける動作(車両ドアロックシステム140の無線通信など)を行う間PLC通信を停止させることにより、車載電子機器14の当該動作にPLC通信が干渉することを防止していた。また実施の形態2で説明したように、充電ケーブル3の漏洩電磁波を抑制する手法の一つに、充電ケーブル3に流れる電流量を小さくする手法がある。
実施の形態4では、車載電子機器14がPLC通信の干渉を受ける動作を行う間、車両1の充電制御装置11からの漏洩電磁波を抑制する技術を示したが、漏洩電磁波は、バッテリ10を充電するための電力を車両1に供給する電力供給装置4からも発生する。電力供給装置4も、車両1への電力供給処理(給電処理)のためのAC/DCコンバータ等の機器を有しており、それらの機器からの漏洩電磁波が車載電子機器14の正常な動作の妨げとなる場合も考えられる。
