Description
<充電システムの全体構成>
図1は、本開示の実施の形態1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10は、車両1と、充電スタンド2と、充電ケーブル3と、サーバ9とを備える。
プラグイン充電においては、ユーザの利便性向上のため、充電時間を短縮することが望まれている。充電時間の短縮は、充電スタンドから供給される充電電力を大電力化することで実現される。しかし、プラグイン充電中には、充電ケーブルのコネクタと車両側のインレットとの接触部分(コネクタ端子とインレット端子との接点)において、接触部分の抵抗値に電流値の2乗を乗算した大きさのジュール熱が熱損失として生じる。そのため、充電電力の大電力化を実現すべく、充電スタンドからの供給電流を増加させると、その分だけ熱損失も増大し、接触部分の過熱が一層懸念されることとなる。したがって、充電ケーブルのコネクタおよびインレットを適切に保護しつつ、できるだけ充電時間を短縮することが求められる。
図3は、実施の形態1におけるプラグイン充電制御を示すフローチャートである。図3および後述する図7に示すフローチャートは、充電ケーブル3のコネクタ310がインレット110に挿入された場合に実行される。図4に示すフローチャートに含まれる各ステップ(以下「S」と略す)は、基本的にはECU100によるソフトウェア処理によって実現されるが、ECU100内に作製された専用のハードウェア(電気回路)によって実現されてもよい。
実施の形態1では、車両1のGPS情報を用いて対象充電スタンドの位置を特定し、充電スタンドの位置情報に基づいて最大許容電流を切り替える構成を例に説明した。しかし、対象充電スタンドの特定に対象充電スタンドの位置情報を用いることは必須ではない。実施の形態2においては、車両1と対象充電スタンドとの通信により最大許容電流を設定する構成について説明する。実施の形態2では、充電テーブルTBL1とは異なる充電テーブルTBL2がECU100のメモリ102に格納されている。実施の形態2における対象充電スタンドおよび車両の上記以外の構成は、図2に示した構成と基本的に同等であるため、説明は繰り返さない。
