    • A battery power monitoring apparatus for use in an electric automobile is provided. The battery power monitoring apparatus determines the amount of available reserve electric power remaining in a storage battery based on electric power discharged from the storage battery to an electric motor and a battery characteristic stored in a memory, representing a relation between a voltage level at which a given level of current flows from the storage battery and the then discharged electric power. The battery characteristic is updated based on the latest detected voltage of the storage battery and current flowing from the storage battery. The battery power monitoring apparatus determines that charge polarization has occurred when a voltage level of the storage battery from which the given level of current flows is increased, and prohibits the updating of the battery characteristic. With this operation, the amount of available electric power is calculated correctly even under the influence of charge polarization.

    • A battery state judging apparatus comprising a voltage detector detecting a voltage at a terminal of a battery, a current detector detecting a charge/discharge current of the battery and an arithmetic operation circuit calculating a residual capacity index of the battery relating to a value obtained by subtracting a quantity of electric charge from a reference capacity value of the battery and calculating a power consumption of the battery from the detected terminal voltage and charge/discharge current. The arithmetic operation circuit estimates a charge/discharge current as a function of the battery residual capacity index and battery power consumption and successively estimates a charge/discharge current in a predetermined power consumption pattern to successively calculate a battery residual capacity index from the estimated charge/discharge current. A battery operable threshold is judged when a battery discharge current, estimated on the basis of an updated battery residual capacity index exceeds a threshold current at that power consumption, and a result is displayed via a display circuit.
