Abstract
【解決手段】電池の電流IBと、組電池の電圧VBと、組電池内の代表の単電池の温度TBとを検出する(ステップS101)。制御装置40に記憶されているマップに基づいて組電池内の単電池間の電圧差ΔVmax,ΔVminを推定する(ステップS102)。電圧差ΔVmax,ΔVminと電圧VBとに基づいて組電池内における単電池の最高電圧Vmaxと最低電圧Vminとを算出する(ステップS103)。最高電圧Vmaxが上限値Vupperを超える場合(ステップS104)、または最低電圧Vminが下限値Vlower未満の場合(ステップS106)、電池の充放電を制御する(ステップS105,S107)。
【選択図】図9
Description
Vmax=VB/N+ΔVmax ・・・(式1)
一方、最低電圧Vminは次の式により算出される。
Vmin=VB/N−ΔVmin ・・・(式2)
ここで、Nは、一つの組電池34を構成する単電池32の個数である。
