  • Publication number: 20190178952
    Abstract: If a charging quantity charged to a battery pack since switching from discharging to charging is more than or equal to a reference charging quantity, an ECU estimates the SOC from the OCV by referring to a charging OCV. If a discharging quantity discharged from the battery pack since switching from charging to discharging is more than or equal to a reference discharging quantity, the ECU estimates the SOC from the OCV by referring to a discharging OCV. If the electric quantity is less than the reference charging quantity or if the electric quantity is more than the reference discharging quantity, the ECU estimates the SOC from the OCV using a straight line for supplementing SOC-OCV characteristics in a region enclosed by the charging OCV and the discharging OCV.

  • Publication number: 20190181510
    Abstract: A secondary battery system includes an electronic control unit (ECU) that estimates surface stress generated in a negative-electrode active material upon incorporation or removal of lithium in a negative electrode of a battery assembly. The ECU calculates an estimated value of the surface stress from a difference obtained by subtracting a reference lithium amount from an amount of lithium contained in the negative-electrode active material, using a linear relationship between the difference and the surface stress. The ECU sets the surface stress to yield stress when the magnitude of the estimated value is larger than that of the yield stress (compressive stress or tensile stress) of the active material, and employs the estimated value as the surface stress when the magnitude of the estimated value is smaller than that of the yield stress.

  • Publication number: 20190145668
    Abstract: A speed estimation apparatus for an AC motor includes a model deviation calculation unit, first and second angular velocity estimation units, and an adder. The deviation calculation unit calculates a model deviation based on a voltage, a current, and an estimated angular velocity of the motor. The first angular velocity estimation unit calculates a first estimated angular velocity as a low-frequency component including a DC component of a real angular velocity based on the model deviation. The second angular velocity estimation unit calculates a second estimated angular velocity as a high-frequency component of a real angular velocity based on a specific high-frequency component of the model deviation. The adder adds the first and second estimated angular velocities together. An addition value of the first and second estimated angular velocities is fed back as the estimated angular velocity to the deviation calculation unit.
