  • Patent number: 8961004
    Abstract: Methods and systems to determine an internal temperature of a rechargeable lithium-ion cell based on a phase shift of the cell. Internal cell temperature may be determined with respect to an internal anode temperature and/or an internal cathode temperature. Internal anode temperature may be determined based on a phase shift of a frequency within a range of approximately 40 Hertz (Hz) to 500 Hz. Internal cathode temperature may be determined based on a phase shift of a frequency of up to approximately 30 Hz. A temperature sensor as disclosed herein may be powered by a monitored cell with relatively little impact on cell charge, may be electrically coupled to cell but housed physically separate from the cell, and/or may monitor multiple cells in a multiplex fashion. A rate of change in phase shift may be used to initiate pre-emptive action, without determining corresponding temperatures.

  • Publication number: 20150049787
    Abstract: Methods and devices for mounting a sensor are presented herein. A temperature sensor assembly for a capacitor bank is disclosed that includes two opposing substrates, and a plurality of contact temperature sensors attached to each substrate. Each temperature sensor is configured to directly contact a surface of one of the capacitor cans in the capacitor bank and therefrom generate a signal indicative of the temperature of the capacitor can. A biasing member attaches the two substrates together. The biasing member is configured to selectively contract, such that the width of the sensor assembly is less than the gap distance between adjacent sets of tandem capacitor cans and the sensor assembly can insert between the sets of capacitor cans, and expand, such that the width of the sensor assembly is greater than the gap distance and the sensor assembly is tensioned against and thereby secured between the sets of capacitor cans.

  • Publication number: 20150010040
    Abstract: A wireless thermometer is provided, which measures a deep temperature with high accuracy and has an improved communication distance. A wireless thermometer includes a flat film-like substrate. A quartz crystal vibrator and an antenna are disposed on a principal surface of the substrate. A quartz crystal vibrator and an antenna are disposed on the other principal surface of the substrate. A winding conductor of the antenna is substantially symmetrical with a winding conductor of the antenna with respect to the substrate. A lead conductor of the antenna is connected to the winding conductor at one end and is connected to the quartz crystal vibrator at the other end. A central portion of the lead conductor is bent. By folding the central portion, the quartz crystal vibrator can be positioned opposite the quartz crystal vibrator with a heat insulator interposed there between.

  • Publication number: 20140376592
    Abstract: The invention relates to a device for representing and displaying the coil temperature of an electrical power transformer and to an electrical circuit suitable therefor. The invention is based on the general concept of using the CT-signal current not only for supplying the heating resistor of a sensor, for example, but also for decoupling energy from the CT-signal current by transformation via an electronic circuit according to the invention in order to supply energy to the connected measurement devices, so that a separate energy source can thus be ultimately omitted.
