Description
<充電システムの全体構成>
図1は、本開示の実施の形態に係る充電システムの全体構成を概略的に示す図である。図1を参照して、充電システム100は、車両1と、充電器2と、充電ケーブル3とを備える。図1には、車両1と充電器2とが充電ケーブル3により電気的に接続され、充電器2から車両1への外部充電時の状況が示されている。
給電力(交流電力)を、車両1に搭載されたバッテリ14の充電電力(直流電力)に変換する。充電器2は、電力線ACLと、AC/DC変換器21と、電圧センサ22と、給電線PL0,NL0と、制御回路20とを含む。
外部充電制御では、車両1と充電器2との間でのメッセージの授受に関する通信シーケンスが進められるとともに、車両1と充電器2との間で電力の授受に関する充電シーケンスが進められる。通信シーケンスおよび充電シーケンスは、いずれも急速充電の充電規格(新規格)に規定されている。以下では通信シーケンスの一例を概略的に説明する。
図4は、充電中止メッセージCSTのデータフィールドの構造(フォーマット)の一例を示す図である。図4を参照して、充電中止メッセージCSTのデータフィールド(いわばメッセージの中身)は、たとえば4バイトのバイト長を有し、以下のような内容を表す。
図6は、比較例における充電中止メッセージCSTの受信時の処理を説明するための概念図である。図6を参照して、比較例における充電器8は、通信シーケンスに規定された内容とは異なる内容を表すデータフィールドを含む充電中止メッセージCSTを車両9に送信する。たとえば図4に示した例では、第1ビットおよび第2ビットの両方が1であって未定義のフィールドCST1を含む充電中止メッセージCSTが送信される。
図7は、本実施の形態における充電中止メッセージCSTの受信時の処理を説明するための概念図である。図7を参照して、本実施の形態においても比較例と同様に、充電器8は、通信シーケンスに規定された内容とは異なる内容を表すデータフィールドを車両1に送信する。
図11は、本実施の形態における外部充電制御の通信シーケンスを示すフローチャートである。図11を参照して、このフローチャートは、車両1と充電器8(充電器2であってもよい)とが充電ケーブル3により接続された状態で低圧電源が投入され、車両1と充電器8との間のCAN通信等が可能となった場合に実行される。各ステップ(以下、ステップをSと略す)は、ECU10によるソフトウェア処理により実現されるが、ECU10内に作製されたハードウェア(電気回路)により実現されてもよい。
