Abstract
Description
中に存在するアラーム状況またはアラーム発生の数(例えば,使用中にサブモジュール22の推奨しきい値を超えたこと)を含む。この情報は、後続の回復のために記録されるある形式の情報を表す。サブモジュール22に関する他の情報も記録される。蓄積された、または記録された情報は、例えば、保証の目的のためにそのサブモジュールが使用されるかを決定するために、サブモジュール22の製造者(または他の適切な団体)によって利用される。サブモジュール22は、サブモジュール22の不良原因を決定しようと試みるために記録された情報にアクセスする製造者へ、顧客から返却される。
主接触器112および事前充電接触回路114が非接続動作モードにあるとき、接触器112,118は個々に開き、電池107をシステム端子101,103に接続された外部装置102から電気的に切り離すように動作する。後述のように、接続動作モードで動作している事前充電接触回路114は、接続動作モードで動作している主接触器112に比べて少ない電流量が流されるように構成される。
106は、電気エネルギーを電池部104から負荷に供給する、または充電電流を充電器から電池部104に供給するために、主接触器112を閉じるように制御する。一実施態様において、主接触器112および事前充電接触回路114の両者は、電池部104をシステム端子101から電気的に切り離すために、動作回路106によって実質的に同時に開けられる。
持するある動作において、改良された動作を提供する。したがって、ある実施態様において、ある部分の故障が存在しても、電気エネルギーは負荷に供給され、または充電のため充電器から受け取る。さらに、ある実施態様は、充電式の電池システムの設計において改良された柔軟性および拡張性を提供し、他の電池システムの設計に比べて、多種多様な応用を可能とする。
