  • Capacitor with cell balancing circuit
    Patent number: 6278604
    Abstract: A multiple cell capacitor (200) includes at least first and second capacitor cells (260) and a cell balancing circuit (265) electrically coupled to the first and second capacitor cells (260). Packaging material (280) encloses the first and second capacitor cells (260) and the cell balancing circuit (265). The cell balancing circuit (265) can include, for each capacitor cell (260), a resistor (265) formed electrically in parallel with that capacitor cell (260).

  • Capacitor
    Patent number: 6088217
    Abstract: A hybrid capacitor with improved energy density employs a cathode including an organic material and optionally a gel, solid, or composite electrolyte material. However, like conventional electrolytic capacitors, said hybrid capacitor employs a valve metal and its respective oxide dielectric layer on the anode side of the cell.

  • Energy storage device with electromagnetic interference shield
    Patent number: 5907471
    Abstract: An energy storage assembly is made of an energy storage device, and electromagnetic interference (EMI) shield, and an adhesive positioned between the EMI shield and the energy storage device for affixing the energy storage device to a surface of the EMI shield. The EMI shield is a metal that is shaped to partially enclose an electrical component other than the energy storage device.
