Patent number: 10315499Abstract: 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: GrantFiled: September 4, 2015Date of Patent: June 11, 2019Assignee: Ford Global Technologies, LLCInventors: Douglas Zhu, Sarav Paramasivam, Dharmendra Patel, Patrick Maguire, Kanghua Chen

Patent number: 9126477Abstract: A battery of a vehicle is cooled by air from a cabin of the vehicle. The air from the cabin flows underneath a rear seat of the vehicle and to the battery.Type: GrantFiled: May 30, 2007Date of Patent: September 8, 2015Assignee: Ford Global Technologies, LLCInventors: Douglas Zhu, Sarav Paramasivam, David Patel, Patrick Maguire, Kanghua Chen

Patent number: 8895171Abstract: Prior to loading into a vehicle, a duct is attached to a battery such that the duct is moveable between a loading position and a post-loading position. Before the battery and duct are loaded into the vehicle, the duct is positioned in the loading position. After the battery and duct are loaded into the vehicle, the duct is positioned in the post-loading position and secured.Type: GrantFiled: October 23, 2007Date of Patent: November 25, 2014Assignee: Ford Global Technologies, LLCInventors: Patrick Daniel Maguire, Sarav Paramasivam, Jeffrey Joseph Omichinski

Patent number: 8679662Abstract: A battery gas discharge system is provided having a floorpan with an outlet and a fastener aperture. The outlet and the fastener aperture are laterally spaced from each other. The system also includes a battery module with a base for resting upon the floorpan. An attachment aperture and a vent aperture are formed through the base. The attachment aperture and the vent aperture are laterally spaced from each other. A gas discharge mechanism defines a passageway for gas discharge between the battery module and the vent aperture. The gas discharge mechanism includes a vent port that is coupled to the vent aperture and sized for receiving discharged gas. The vent port is adapted for mating with and forming a seal about the outlet by securing the base to the floorpan during assembly.Type: GrantFiled: January 4, 2011Date of Patent: March 25, 2014Assignee: Ford Global Technologies, LLCInventors: Patrick Daniel Maguire, Sarav Paramasivam, Hari Addanki

Patent number: 8394525Abstract: A battery includes a plurality of stacking supports including retaining flanges and support surfaces; and a plurality of generally cylindrical cells. Each cell is supported on a pair of the support surfaces. Each cell has an annular notch defined in a side wall with the annular notch mating with one retaining flange. The cells are arranged upon the stacking supports in a plurality of cell rows. The support surfaces are arranged on the stacking supports in such a manner so that the cells are arranged in a close-packed array and to maintain at least a predetermined distance between adjacent cells.Type: GrantFiled: June 22, 2010Date of Patent: March 12, 2013Assignee: Ford Global Technologies, LLCInventors: Patrick Daniel Maguire, Sarav Paramasivam

Patent number: 8323818Abstract: An end-to-end cell connection system for a battery assembly uses a conductive interconnector with an inner portion welded to an end of one cell, a standoff portion contiguous with the ring portion, tabs extending from the standoff portion, with the tabs welded to an end of another cell. By placing an insulator between the interconnector and the one cell, an electrical short is prevented in the event that a longitudinally coupled cell group is jostled. At the cell connections, there is a recess. To hold the cell group in place, the housing has a tab extending into the recess. The tab is at the center so that any dimensional variations are accommodated on each side of the tab. The interconnector also may include a receptacle for a thermistor to obtain a measure of battery assembly temperature. Diverter ribs may be provided in the housing to distribute flow to all cells.Type: GrantFiled: March 25, 2010Date of Patent: December 4, 2012Assignee: Ford Global Technologies, LLCInventors: Patrick Daniel Maguire, Sarav Paramasivam
