  • Patent number: 10315499
    Abstract: A vehicle includes a floor, a seat including a back, and a traction battery module located behind the seat. The seat and floor form an air passageway, underneath the seat, from a cabin to the traction battery module. The vehicle also includes a plenum disposed between the air passageway and fraction battery module, and a sealing member fixed to the plenum and configured to engage the back to form a substantially airtight seal therebetween.
    Type: Grant
    Filed: September 4, 2015
    Date of Patent: June 11, 2019
    Assignee: Ford Global Technologies, LLC
    Inventors: Douglas Zhu, Sarav Paramasivam, Dharmendra Patel, Patrick Maguire, Kanghua Chen

  • Patent number: 7301755
    Abstract: Power converters such as power modules configured as inverters employ modularized approaches. In some aspects, semiconductor devices are thermally coupled directly to thermally conductive substrates without intervening dielectric or insulative structures. Additionally, or alternatively, semiconductor devices are thermally coupled to thermally conductive substrates with relatively large surface areas before heat transferred from the semiconductor devices encounters a dielectric or electrically insulating structure with correspondingly high thermal impedance.
