摘要:
A method and an apparatus for computing a charging state of a battery without being affected by an influence of polarization are provided. First computing means computes a voltage-current characteristic including the influence of the polarization during an decrease of a discharge current of the battery on the basis of a terminal voltage and discharge current measured while the battery carries out a constant load discharge with a current value large enough to cancel a charge-side polarization arisen in the battery at least just before the discharge. A second computing means shifts the voltage-current characteristic to a specific extent in the direction of a voltage coordinate axis. A residual voltage drop value in advance stored by storing means is added to a present estimated voltage value estimated by estimating means on the basis of the shifted voltage-current characteristic, thereby a present open circuit voltage of the battery is computed.

A microcomputer monitors, on the basis of outputs from a current sensor and voltage sensor, a voltage drop due to an internal resistance when the drop in the terminal voltage due to polarization occurring during the discharge of a battery is saturated, and a dischargeable capacity of the battery corresponding to the value resulting when the saturated voltage drop of the terminal voltage is subtracted from the chargeable capacity of the battery. Such a configuration provide a battery status monitoring device capable of knowing the battery status correctly, a saturation polarization detecting method which is useful to know the charging state of the battery and a dischargeable capacity detecting method.

A unit for estimating voltage drop 23a-1 estimates voltage drop of a battery terminal when maximum current is continuously supplied at high rate discharge. A unit for estimating residual discharge capacity 23a-2 estimates residual discharge capacity of the battery for allowing the maximum current to be continuously supplied to a load by subtracting the undischargeable electric charge calculated from the voltage drop estimated by the unit for estimating voltage drop 23a-1 from the dischargeable charge in any state of charge.

摘要:
A remaining capacity measuring apparatus of this invention operates as follows. A current value and a voltage value from a current sensor and a voltage sensor respectively provided in a battery connected to a hybrid mechanism portion are sampled every 1 millisecond. Each time when eight pairs (N1) of this current value data and voltage value data are collected, the current values and voltage values are each averaged. When 100 pairs (N2) of the average current values and the average voltage values are obtained, the 100 pair data are plotted on a voltage-current coordinate system. A correlation between the current and voltage is obtained based on the plural data plotted on this coordinate system. When a strong negative correlation is indicated, an approximate line indicating a relation between the voltage and current is obtained. By substituting a predetermined current value for this line, a voltage value is defined and a value corresponding to this voltage value is regarded as a current remaining capacity.
