  • Patent number: 9899658
    Abstract: A high current fuse with a short time constant is provided for use in an electric vehicle. The fuse is designed to exhibit thermal characteristics that are similar if not substantially identical to those of the wire bond interconnects used in the vehicle's battery pack. As a result, the system does not go into an overheat protection condition when the system is subjected to repetitive high current cycles, such as those common during aggressive and/or spirited driving.

  • Patent number: 9819052
    Abstract: A secondary battery capable of safely improving a battery performance is provided. An electrolyte with which a separator 13 is impregnated contains an alkyl sulfone and a low-polar solvent (a solvent having a relative permittivity of 20 or less) together with an aluminum salt. The alkyl sulfone facilitates the redox reaction of aluminum, and further reduces the reactivity of the electrolyte. Additionally, the low-polar solvent suppresses the block of the redox reaction of aluminum. In charge and discharge, it becomes easy to electrochemically efficiently precipitate and dissolve aluminum, and further to inhibit the corrosion of a metallic exterior package member or the like.
