Abstract
Description
第2アダプターは、バッテリの状態情報を取得することができる。バッテリの状態情報は、バッテリの現在の電気量情報及び/又は電圧情報を含むことができる。第2アダプターは、取得されたバッテリの状態情報に基づいて第2アダプター自身の出力電圧を調節することにより、バッテリの予期充電電圧及び/又は充電電流の需要を満たすことができる。さらに、バッテリの充電プロセスの定電流充電段階において、第2アダプターによって調節された後の出力電圧は、バッテリの両端に直接印加してバッテリを充電することができる。
充電対象機器(例えば端末)が電源提供装置に接続された後、充電対象機器(例えば端末)は、データケーブルD+,D−を介して電源供給装置のタイプを検出することができる。電源供給装置が第2アダプターであることを検出した場合に、充電対象機器(例えば端末)が受け入れた電流は、所定電流閾値I2(例えば、1Aであっても良い)より大きくても良い。第2アダプターにおける制御ユニットが所定持続時間(例えば、連続的なT1時間)内での第2アダプターの出力電流がI2以上であることを検出した場合に、制御ユニットは、充電対象機器(例えば端末)が電源供給装置のタイプを認識することが既に完成されたと判定しても良い。制御ユニットは、第2アダプターと充電対象機器(例えば端末)との間のネゴシエーションプロセスを開始し、充電対象機器(例えば端末)にコマンド1(上記第1コマンドに対応する)を送信して、充電対象機器(例えば端末)は第2アダプターが第2充電モードで充電対象機器(例えば端末)を充電することに同意するか否かを尋ねる。
第2アダプターの出力電圧は、複数のグレードを含んでいても良い。制御ユニットがコマンド2(上記第2コマンドに対応する)を充電対象機器(例えば端末)に送信して、第2アダプターの出力電圧(現在の出力電圧)と充電対象機器(例えば端末)のバッテリの現在の電圧とがマッチングしているか否かを尋ねる。
制御ユニットは、コマンド3(上記第3コマンドに対応する)を充電対象機器(例えば端末)に送信して、充電対象機器(例えば端末)の現在サポートする最大充電電流を尋ねる。充電対象機器(例えば端末)はコマンド3の返事コマンドを制御ユニットに送信し、充電対象機器(例えば端末)の現在サポートする最大充電電流を指示して、段階4に移行する。
制御ユニットは、充電対象機器(例えば端末)の現在サポートする最大充電電流に基づいて、第2充電モードでの第2アダプターから出力された充電対象機器(例えば端末)を充電するための充電電流を決定した後、段階5、即ち定電流充電段階に移行する。
定電流充電段階に移行した後、制御ユニットは、一定時間ごとにコマンド4(上記第4コマンドに対応する)を充電対象機器(例えば端末)に送信し、充電対象機器(例えば端末)のバッテリの現在の電圧を尋ねることができる。充電対象機器(例えば端末)は、コマンド4の返事コマンドを制御ユニットに送信して、充電対象機器(例えば端末)のバッテリの現在の電圧をフィードバックする。制御ユニットは、充電対象機器(例えば端末)のバッテリの現在の電圧に基づいて、充電インターフェースの接触が良好であるか否か、及び第2アダプターの出力電流を低減する必要があるか否かを判断することができる。第2アダプターが充電インターフェースの接触が不良であると判断した場合に、コマンド5(上記第5コマンドに対応する)を充電対象機器(例えば端末)に送信することができ、第2アダプターは、第2充電モードを終了し、リセットして再度に段階1に移行する。
