なお、ここでVmaxは蓄電手段の定格最大電圧又は接続される負荷等のシステム上規定される最大電圧値であり、Vminは蓄電手段の定格最小電圧又は接続される負荷等のシステム上規定される最小電圧値である。
Ia=Iall−(Rb+Rcb)/(Ra+Rb+Rca+Rcb) ・・・(3)
Ib=Iall−(Ra+Rca)/(Ra+Rb+Rca+Rcb) ・・・(4)
Ia=Iall−(Rb+Rcb)/(Ra+Rb+Rca+Rcb)<(Vmax−E)/(Ra+Rca) ・・・(5)
Ib=Iall−(Ra+Rca)/(Ra+Rb+Rca+Rcb)<(Vmax−E)/(Rb+Rcb) ・・・(6)
Ia=Iall−(Rb+Rcb)/(Ra+Rb+Rca+Rcb)<(E−Vmin)/(Ra+Rca) ・・・(7)
Ib=Iall−(Ra+Rca)/(Ra+Rb+Rca+Rcb)<(E−Vmin)/(Rb+Rcb) ・・・(8)
Ia=Iall×Ra/(Ra+Rb) ・・・(9)
となり、また、シリーズユニット21bに流入する電流量Ibは、
Ib=Iall×Rb/(Ra+Rb) ・・・(10)
となる。なお、ここでもシリーズユニット21a,bの2つが互いに並列に接続されている例を想定している。
Ia=Iall×Rb/(R1+R2+Rb) ・・・(11)
となる。この値は、蓄電池B1交換前のシリーズユニット21aに流れる電流量Ia′(次の(12)式)に比べ、大きくなっている。
Ia′=Iall×Rb/(2×R2+Rb) ・・・(12)
