Ith=Vr/(R1+R2) ・・・(I)
ここで、Iは、各組電池10,20に流れる電流を示し、Rは、各組電池10.20の内部抵抗を示す。
ΔV=Ij(R1+R2) ・・・(2)
式(2)において、R1は、組電池10の内部抵抗を示し、R2は、組電池20の内部抵抗を示す。
ΔV≦Vr ・・・(3)
Ij≦Vr/(R1+R2)=Ith ・・・(4)
ΔVmax=I(Rmax−Rmin)/2 ・・・(5)
ここで、ΔVmaxは、組電池10,20の間におけるOCVの差が最大となるときの値である。また、ΔVmaxは、システムメインリレーSMR−Gをオンからオフに切り替えたときのOCVの差である。kは定数であり、tは時間である。Rmaxは、劣化状態が最大となる組電池10の抵抗であり、Rminは、劣化状態が最小となる組電池20の抵抗である。
