Description
しかし、使用されるバッテリーの種類が変われば、セルの特性も変わり、その場合、バッテリーに接続されるバッテリー管理装置も、セルの特性に合わせて最適化された管理基準を有するものに交換されねばならない。
しかし、最近、バッテリーのモデルがますます多様化するにつれて、バッテリーのモデル毎に相異なるバッテリー管理装置を適用することが困難であり、また単一システムで使用されるバッテリーの数の急増によって、今後、同一システム内で多様なモデルのバッテリーが混用される可能性も高まっているため、システム運用がますます難しくなる恐れがある。
望ましくは、前記バッテリー情報は、バッテリーのモデル情報及び特性情報のうち少なくとも一つを含むことができる。
望ましくは、前記バッテリーの特性情報は、定格電流、定格電圧、定格容量、開路電圧(OCV:Open Circuit Voltage)、充電率(SOC:State Of Charge、及び充放電出力許容値に関する情報のうち少なくとも一つの情報を含むことができる。
望ましくは、前記バッテリー情報は、前記バッテリーのモデル情報を含むことができる。
望ましくは、前記バッテリー管理装置は、前記バッテリーのモデル情報に対応するバッテリーモデルに関する前記特性情報を参照して、管理基準を最適化することができる。
望ましくは、前記バッテリー管理装置には、基本管理基準が設定され得る。
望ましくは、前記バッテリー情報記憶装置は、メモリーカードであり得る。
望ましくは、前記バッテリー管理装置は、前記バッテリー情報記憶装置に接続される外部コネクターを備えることができる。
望ましくは、前記バッテリーは、前記外部コネクターに接続される接続ポートを備えることができる。
望ましくは、前記バッテリーは、前記バッテリー情報記憶装置が差し込まれる第1差込口を備えることができる。
望ましくは、前記バッテリー情報記憶装置は、前記バッテリーに内蔵され得る。
望ましくは、前記バッテリー管理装置は、前記バッテリー情報記憶装置が差し込まれる第2差込口を備えることができる。
また、本発明は、バッテリー管理装置に接続されて前記バッテリー管理装置にバッテリー情報を提供するバッテリー情報記憶装置を提供し、前記バッテリー情報は、前記バッテリー管理装置のバッテリー管理基準を最適化する際に参照される。
望ましくは、前記バッテリー情報記憶装置は、バッテリーに内蔵又は脱着されるものであり得る。
望ましくは、前記バッテリー情報記憶装置は、前記バッテリー管理装置に脱着されるものであり得る。
図1は、本発明によるバッテリー特性自動認識システムを示したブロック図であり、図2a及び図2bは、本発明によるバッテリー及びバッテリー情報記憶装置を示した斜視図である。
図1〜図3を参照すれば、本発明によるバッテリー特性自動認識システム1は、バッテリー10、バッテリー情報記憶装置20、及びバッテリー管理装置30を含む。
前記バッテリー10は、少なくとも一つのセル(図示せず)、ケース11、及び外部端子12を含む。
前記電気自動車の場合、消耗したバッテリーを充電所で直接充電して、運行に必要な電力を供給される場合の外に、予め用意した充電済みのバッテリーに入れ替えて使用することもできる。このような場合、相異なる特性を有するバッテリーが混用され得るが、本発明によるバッテリー特性自動認識システム1を適用する場合、従来のバッテリー管理装置30をそのまま使用することができる。
前記電力貯蔵システムの場合も、一般に非常に多数のバッテリーが使用されるため、多様なモデルのバッテリーが混用され得るが、本発明によるバッテリー特性自動認識システム1を適用する場合、バッテリーモデルの種類に関係なく従来のバッテリー管理装置30をそのまま使用することができる。
図3は、本発明によるバッテリー管理装置の最適化方法を示したフロー図である。
図3を参照すれば、本発明によるバッテリー管理装置の最適化方法は、バッテリー情報記憶装置20を接続する段階S1、バッテリー情報を認識する段階S2、及び管理基準を最適化する段階S3を含む。
なお、前記バッテリー管理装置30は、S1段階においてバッテリー情報記憶装置20がバッテリー管理装置30に接続されていない場合、予め設定された基本モデルに関する特性情報を利用して、管理基準を最適化する。
すなわち、それぞれの構成は、本発明の技術思想を実現するための論理的な構成要素に該当するため、各構成要素が統合または分離されても、本発明の論理構成による機能を実現できれば、本発明の範囲内であると解釈されねばならず、同一または類似の機能を果たす構成要素であれば、その名称の一致如何とは関係なく、本発明の範囲内であると解釈されねばならないことは勿論である。
