摘要: Means for estimating the charged state of a battery, capable accurately an SOC even though battery repeats charging/discharging in short cycles. The current Ib measured by sensing means (10) is integrated, and pseudo-SOC estimates pseudo-SOC. Electromotive force (16) open voltage Voc from Voltage change (18) Vr due to internal resistance Ib. Dynamic (20) Vdyn current. An adder (22) adds Voc, Vr, calculate estimated Vest battery. correction calculating (26) calculates equalizing Vmes (12), (28) estimate
