  • Method and apparatus for protection of batteries
    Patent number: 7019493
    Abstract: The protection circuit (30) comprises at least one switch (FET1, FET2) comprising at least one control means (G1, G2) for adjusting the conductivity of said at least one switch (FET1, FET2). The conductivity is arranged to be adjustable by means of an electrical control conducted to the control means (G1, G2).
    Type: Grant
    Filed: October 8, 2004

  • Battery pack for electronic device
    Patent number: 6803144
    Abstract: A battery pack for use with a cellular telephone device includes a flat battery cell assembly encased by a resin using low temperature molding techniques or injection molding techniques under low pressure. An interface assembly cap provides an electrical connection means between the cell assembly and the cellular telephone device with which it is used. The resin molded cell assembly accommodates a smaller physical size than preformed plastic battery packs without sacrificing relative available power density.
