Description
図1は、第1の実施形態に係る蓄電システム10の構成を示すブロック図である。蓄電システム10は、複数の蓄電モジュール100と、管理装置200とを備える。
第2の実施形態では、基準電圧GND2を分圧回路で生成する点において、第1の実施形態と異なる。以下では、第1の実施形態との相違点を中心に説明する。
少なくとも1つのセル(C1)をそれぞれ有し、直列接続された複数の蓄電モジュール(100)と、
前記複数の蓄電モジュール(100)を管理する管理装置(200,200A)と、を備え、
前記複数の蓄電モジュール(100)は、それぞれ、前記複数の蓄電モジュール(100)の一端の電圧(Vout)と他端の電圧(GND1)の間の予め定められた基準電圧(GND2)を基準とする信号であって、前記少なくとも1つのセル(C1)の情報を含む信号を通信線(L2)に出力する、一次側と二次側が絶縁された第1絶縁部(110)を有し、
前記管理装置(200,200A)は、一次側と二次側が絶縁された第2絶縁部(204)と、前記第2絶縁部(204)により前記通信線(L2)と絶縁される回路部(206)とを有することを特徴とする蓄電システム(10,10A)。
これによれば、通信遅延の増加を抑制した上で、第1絶縁部(110)の耐圧を低減させることができる。
[項目2]
前記基準電圧(GND2)は、予め定められた隣接する2つの蓄電モジュール(100)の間のノード(n1)の電圧であることを特徴とする項目1に記載の蓄電システム(10)。
これによれば、基準電圧(GND2)を簡単な構成で取得できる。
[項目3]
前記管理装置(200A)は、前記複数の蓄電モジュール(100)の両端電圧を分圧して、前記基準電圧(GND2)を出力する分圧回路(210)を備えることを特徴とする項目1に記載の蓄電システム(10A)。
これによれば、基準電圧(GND2)を任意の値に容易に設定できる。
[項目4]
前記基準電圧(GND2)は、前記複数の蓄電モジュール(100)の一端の電圧(Vout)と他端の電圧(GND1)の中点電圧であることを特徴とする項目1から3のいずれかに記載の蓄電システム(10,10A)。
これによれば、第1絶縁部(110)の耐圧を最小に近づけることができる。
[項目5]
前記管理装置(200,200A)は、前記第1絶縁部(110)と前記第2絶縁部(204)に駆動電力を供給する電源回路(208)を有し、
前記複数の蓄電モジュール(100)と前記管理装置(200,200A)の間の信号伝送は、前記電源回路(208)の電力供給で行われることを特徴とする項目1から4のいずれかに記載の蓄電システム(10,10A)。
これによれば、電源電圧(V2)を適切に供給できる。
