Description
(d)=|(t1)−(t2)|
であり、(d)は、電池内の欠陥の大きさに対応する。
(d)=|(t1)−(t2)|
であり、(d)は、電池内の欠陥の大きさに対応する。
(d)=|(t1)−(t2)|
であり、(d)は、電池内の欠陥の大きさに対応する。
添付図面は、本明細書に組み込まれ、本明細書の一部をなし、様々な実施形態を示し、本明細書とともに、本発明の原理を説明する役割を果たす。
図1は、電池の劣化を測定する方法100の例示的フローチャートを示す。各種実施形態では、110で、電池についての安全電圧および電流制限を決定することが可能である。安全電圧および電流制限は、既知の電池特性から設定されることが可能である。この情報は、電池の製造元から提供される場合がある。
(d)=|(t1)−(t2)| [1]
各種実施形態によれば、差分(d)は、電池内に存在する欠陥(潜在的容量劣化欠陥など)の度合いに関連する。さらに、遅延量(D)は、電池の状態を表すものとして測定されることが可能である。たとえば、(d)の値が(D)より大きければ、図1の190で示されるように、潜在的容量欠陥が存在する可能性がある。正常な電池であれば、(d)は、所定の遅延量(D)より小さいはずである。したがって、正常な電池の場合の(d)は、最小、すなわち、ゼロであるはずである。
図7は、鉛蓄電池の容量劣化を測定できるシステム700の例示的構成を示す。各種実施形態では、例示的システム700は、制御コンピュータ710、計測および制御モジュール720、制御リレー730、電流センサ740、電源760など、様々なモジュールを含む。このシステムは、複数の個別モジュールとして描かれているが、単体(たとえば、Honeywell TruCharge(商標)アナライザ/チャージャなど)の形で実装されることが可能である。図7にはさらに、電池750(鉛蓄電池など)が示されている。各種実施形態では、システム700はさらに、電池750の容量劣化などの事柄を表示するディスプレイを含むことも可能である。
