    摘要： Regarding a method for determining battery discharge capability of the present invention, the optimum state vector X is estimated by extended Kalman filter operation. Using the estimated state vector X, element parameters of an equivalent circuit 21 are renewed to the optimum (step S7). Furthermore, based on the equivalent circuit 21 using the renewed element parameters, at the time of discharging with a predetermined current pattern from a battery 12, a voltage drop ΔV is estimated (step S8). Therefore the discharge capacity of the battery 12 is determined (step S9).

    摘要： A method for detecting SOC and SOH of a storage battery includes: calculating an SOC value of the storage battery with use of an SOC calculation unit based on a measured voltage value or a measured current value of the storage battery and calculating an SOH value of the storage battery with use of an SOH calculation unit based on the SOC value; further calculating a new SOC value with use of the SOC calculation unit based on the SOH value and calculating a new SOH value with use of the SOH calculation unit based on the new SOC value, these further calculations of SOC value and SOH value being repeated a prescribed n times of at least one so as to obtain an nth calculated SOC value and an nth calculated SOH value; outputting the nth calculated SOH value as an SOH output value and outputting the nth calculated SOH value as an SOC output value; and storing the SOH output value into a memory.
