  • Patent number: 8583389
    Abstract: A plurality of resistance value tables of a battery group with respect to temperature and SOC of the assembled battery, which are measured in advance when currents of different change patterns flow in the assembled battery, are stored. A resistance value for the assembled battery is calculated, based upon its voltage and current. From among the plurality of resistance value tables, a resistance value table is selected so that it corresponds to the change pattern of the current flowing in the assembled battery when the voltage and the current of the assembled battery were measured, and a resistance value is searched for from that resistance value table corresponding to the temperature and the SOC of the assembled battery. Then the calculated resistance value and the one from the table are compared to determine the life of the assembled battery.

  • Patent number: 8554499
    Abstract: A method for detecting a defect in an electric link, which transmits, at a first moment, an electric signal having a predetermined propagation speed from an end of the electric link, and detects, at a second moment, reception of an echo of the electric signal. The method further establishes a model of the variation of the electric signal propagation speed in the electric link on the basis of the length of the link through which the signal flows, and estimates a first location of the defect based on the difference between the first and second moments, on the predetermined propagation speed at the start, and on the speed variation model in the link.

  • Patent number: 8510071
    Abstract: A method is provided for calibrating voltage values and current values detected by a high-frequency measuring device. In a first step, a first parameter is calculated based on impedances calculated when the measuring device is connected to a first set of three reference loads and impedances of the first set of three reference loads. In a second step, plasma processing is carried out with the measuring device connected to a load to be measured, and detected voltage and current values are calibrated using the first parameter, and impedances as viewed from a connection point towards the load side are calculated based on the calibrated voltage and current values. In a third step, three impedances that encompass, when displayed on a Smith chart, a narrower range than a range encompassed by the impedances of the first set of three reference loads are determined, where the narrower range includes the impedances calculated in the second step.
