  • Patent number: 9316546
    Abstract: A flexible board includes a base layer, a wiring conductor layer that is located on the base layer, and a cover layer that is stacked over the base layer and covers the wiring conductor layer. A portion of the wiring conductor layer defines connecting portions that connect each of split electrodes of a flexible thermistor. The cover layer includes an opening that exposes the connecting portions, and receives the flexible thermistor. The split electrodes of the flexible thermistor are mounted on the connecting portions of the wiring layer. The height of the exposed surface of the flexible thermistor from the opening is substantially equal to the height of the surface of the cover layer.

  • Patent number: 7550950
    Abstract: A battery pack includes a first switching element which shuts off a discharging current flowing to a battery cell and a second switching element which shuts off a charging current. A positive temperature coefficient thermistor is inserted between a gate control terminal of a protective control circuit and a gate of at least one of the switching elements, and a resistor is connected between the gate and a source of the switching element. The positive temperature coefficient thermistor is thermally connected to one or more of the first and second switching elements and/or to the battery cell. Thus, an abnormally overheated state of one or more of the switching elements or the battery cell leads to an increase in the resistance of the positive temperature coefficient thermistor causing shut-off of the switching element thereby protecting the battery pack.
