PROBLEM TO BE SOLVED: To simply and accurately estimate the remaining amount of an electric dipole layer capacitor. SOLUTION: The detected terminal voltage Vout of the electric dipole layer capacitor and a charge-discharge current (i) are read (S100), and the input to a state equation using residue Ve (aVe hat) as a state variable and residue is calculated, while a voltage drop section Ri is calculated from the detected charge-discharge current (i) and an internal resistance R and subtracted from a detected terminal voltage Vout and an estimated terminal voltage Vest is calculated (S102), and the difference in detected terminal voltage Vout and calculated estimated terminal voltage Vest is multiplied by an observer gain Kc by, using an observer for estimating remaining and residue the remaining amount is corrected (updated) (S104). |
