    摘要: The invention provides a battery condition estimating method and a power system permitting to estimate aging level or discharge ability of a battery in high precision by reducing transient changes of response voltages caused by repetitive discharges. A recovery time after a discharge is prolonged with a number of times of discharge and a relationship between the number of times of discharge and the recovery time is approximated by using an exponential function in the battery condition estimating method of the invention. A discharge pattern as shown in FIG. 1 is formed by using the recovery time obtained from this approximation and substantially constant response voltage is obtained by discharging the battery in accordance to this discharge pattern. Then, impedance during a metastable condition is calculated from the measured response voltage and the discharge current and the aging level or the discharge ability of the battery is determined from the impedance.

    摘要: A method for determining battery discharge capability includes estimating the optimum state vector X by an extended Kalman filter operation. Using the estimated state vector X, element parameters of an equivalent circuit are renewed. Furthermore, based on the equivalent circuit using the renewed element parameters, at the time of discharging with a predetermined current pattern from a battery, a voltage drop ΔV is estimated. Therefore, the discharge capacity of the battery is determined.

    摘要: A vehicular use power feed apparatus comprising a battery and a plurality of power distribution units connected in a loop via power feed lines. Each power distribution unit has a current monitoring circuit, a current amount determination circuit, and a current direction determination circuit, detects the direction of current and magnitude of current flowing through the power feed line, and thereby detects an occurrence of a short-circuit. A control unit exchanges information regarding occurrence of short-circuits with adjoining power distribution units via a multiplex signal transmission unit so as to pinpoint the trouble point. The control unit operates the relay switch circuits on the two sides to break the connection so as to isolate the trouble point in cooperation with the control unit of the adjoining power distribution unit. The other relay switch circuit is operated to establish a connection so as to establish a new power feed line.
