  • Publication number: 20130149565
    Abstract: A magnetic sensor for measuring the magnetic properties of a battery cell, and converting the magnetic properties to a battery cell SOC. The magnetic sensor includes a magnetic core formed of laminated high permeability plates provided in a C-shape. An extended portion of the battery cell extends through a transverse opening in the core so that it is positioned within the core. A driving coil is wrapped around one end of the magnetic core and generates a magnetic field in the core that extends across the transverse opening and through the battery cell. A receiving coil is wrapped around an opposite end of the core that receives the magnetic field, and converts the magnetic field to a representative current. A detection circuit converts the receiving coil current to the battery cell SOC.

  • Patent number: 8216432
    Abstract: This invention relates to novel methods for affecting, controlling and/or directing various reactions and/or reaction pathways or systems by exposing one or more components in a fuel cell reaction system to at least one spectral energy pattern. In a first aspect of the invention, at least one spectral energy pattern can be applied to a fuel cell reaction system. In a second aspect of the invention, at least one spectral energy conditioning pattern can be applied to a conditioning reaction system. The spectral energy conditioning pattern can, for example, be applied at a separate location from the reaction vessel (e.g., in a conditioning reaction vessel) or can be applied in (or to) the reaction vessel, but prior to other reaction system participants being introduced into the reaction vessel.

  • Patent number: 8129046
    Abstract: A battery pack system may include a battery pack and a battery pack holder. The battery pack holder receives the battery pack and couples a battery pack terminal to a load associated with the battery pack holder. The battery pack includes an operation handle external to a battery pack housing. The operation handle is coupled to an operation member via an operation shaft that passes through the housing. A safety circuit of the battery pack couples power supplied by a battery to battery pack terminals based upon position of the operation handle. An operation member of the battery pack extends a locking member into an opening of the battery pack holder when the operation handle is in the engaged position, and retracts the locking member from the opening when the operation handle is in the disengaged position.
