  • Publication number: 20240186809
    Abstract: A bipolar LFP battery includes a plurality of cells that are stacked together. A positive electrode active material layer of each of the cells includes lithium iron phosphate. A ?Q calculation unit calculates an increase ?Q of a charge amount, during charging of the cell of the bipolar LFP battery. The increase ?Q is an increase in the charge amount of the cell when the voltage of the cell increases from a first voltage to a second voltage. A full charge capacity estimation unit uses a full charge capacity map to estimate the full charge capacity of the cell, using the increase ?Q of the charge amount as a parameter.

  • Publication number: 20240068422
    Abstract: An upstream integrated value is an integrated value of a difference obtained by subtracting an upstream gas temperature at a starting point in time of integration from the upstream gas temperature after starting of the internal combustion engine. A downstream integrated value is an integrated value of a difference obtained by subtracting a downstream gas temperature at the starting point in time of the integration from the downstream gas temperature after the starting of the internal combustion engine. An anomaly diagnosing process obtains an anomaly determination result indicating that the exhaust purification device is in a removed state when a deviation between the upstream integrated value and the downstream integrated value is smaller than a reference level. The determination threshold is higher than a dew point.

  • Publication number: 20240036028
    Abstract: A method of measuring stable hemoglobin A1c by a hemoglobin separation analysis method based on cation exchange, the method comprising: obtaining an analysis signal from a blood specimen to be measured by the separation analysis method; determining a C value, which is a peak value of a stable hemoglobin A1c peak, and an X value, which is a peak value of a specific peak appearing between the stable hemoglobin A1c peak and a hemoglobin A0 peak, from the analysis signal; and correcting the C value by applying the C value and the X value to a predetermined arithmetic expression to obtain a C? value that is a reduced value from the C value, wherein the arithmetic expression is determined based on a correlation between a C value and an X value obtained from a blood specimen in which a stable hemoglobin A1c value is known by the separation analysis method.
