Abstract
Description
上記関係式において、「R」は内部抵抗、「IB」は実電流、「VBs」は実電圧を示す。この実施の形態では、平均セル電圧(すなわち、各セル111の電圧の平均値)を、VBsとして採用する。ただしこれに限られず、平均セル電圧に代えて、最大セル電圧(すなわち、各セル111の電圧のうち最も高い電圧値)、最小セル電圧(すなわち、各セル111の電圧のうち最も低い電圧値)、又は組電池の端子間電圧(すなわち、SMR14が閉状態であるときに外部接続端子T1,T2間に印加される電圧)を、VBsとして採用してもよい。第1推定部611は、電池センサ信号(特に、電圧信号VB)を用いてVBsを取得することができる。上記の関係式は、予め記憶装置60c(図2)に記憶されている。なお、上記の関係式は、所定の補正項(たとえば、分極に関する補正項)を含んでもよい。
再び図4とともに図5を参照して、演算部612は、第1推定部611によって取得されたV1を用いて、IWinをWinに変換する。より具体的には、演算部612は、下記式F1に示す演算を行なってIWinをWinに変換する。式F1は、予め記憶装置60c(図2)に記憶されている。
演算部612は、第1推定部611からV1を受け取り、電池パック10(図4)から入力されるIWinにV1を乗算する。このように、演算部612は、上記式F1に従い、IWinとV1とを乗算することにより、IWinをWinに変換する。
演算部622は、第2推定部621からV2を受け取り、電池パック10(図4)から入力されるIWoutにV2を乗算する。このように、演算部622は、上記式F2に従い、IWoutとV2とを乗算することにより、IWoutをWoutに変換する。
今回開示された実施の形態は、すべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は、上記した実施の形態の説明ではなくて特許請求の範囲によって示され、特許請求の範囲と均等の意味及び範囲内でのすべての変更が含まれることが意図される。
