  • Publication number: 20220006151
    Abstract: A high strength frame of a sealable containment system is provided for containing and protecting energy cells or batteries. The protection provided by the high strength frame provides impalement resistance, impact resistance, fire resistance, and fluid penetration prevention. The frame includes a shock structure/energy absorber to protect the battery from forces during potential impacts with other vehicles or objects. The frame of a battery containment system is further designed to resist impalements in order to protect the batteries. Furthermore, because vehicle batteries are prone to extreme fire in the event of an impact or impalement, the containment system provides a sealed battery environment to keep fluid and moisture out during normal operation and to limit oxygen in the event of a battery fire.

  • Patent number: 10807666
    Abstract: In the vicinity of a front end of a plate-shaped member of a fiber reinforced resin material having long fibers, to suppress deterioration in strength due to waviness of the long fibers during press-molding. The plate-shaped member is formed by a discontinuous fiber reinforced resin having long fibers. A flat surface part of the plate-shaped member is provided with a hole part, and a side wall is integrally formed to a semicircular end of the flat surface part located closer to the hole part. The side wall is arranged in a region between an opening edge of the hole part closer to a front end, and the front end so as to extend around its outer circumference.
