Patent number: 11884166Abstract: Reinforcement assemblies and associated methods are provided for reinforcing a battery pack of an electrified vehicle. An exemplary battery pack may include a battery internal component (e.g., a battery array), an enclosure assembly for housing the battery internal component, and a reinforcement assembly secured to the enclosure assembly. The reinforcement assembly may include a beam and a bracket secured to the beam. The reinforcement assembly may be positioned at expected high impact load locations of the enclosure assembly and is configured for absorbing and transferring energy during vehicle impact loading events, thereby minimizing transfer of the impact loads inside the battery pack where relatively sensitive battery internal components are housed.Type: GrantFiled: January 7, 2022Date of Patent: January 30, 2024Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Shamsuddin A. Syed, Ihab Grace, Mumtaz Hussain, David J. Pfeiffer

Patent number: 11724604Abstract: This disclosure details battery assemblies for use within electrified vehicle battery packs. An exemplary battery assembly includes a grouping of battery cells and an array plate assembly contacting a portion of the battery assembly. The array plate assembly may embody a split panel design that includes an outer panel and an inner panel that are arranged to nest together. One or both of the outer panel and the inner panel may include an embossing pattern. Among various other advantages, the split panel design increases the stiffness of the array plate assembly without significantly increasing the overall package depth of the array plate assembly or the battery assembly.Type: GrantFiled: June 25, 2018Date of Patent: August 15, 2023Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Saravanan Paramasivam, Rajaram Subramanian, Mallikarjun Veeramurthy, Bhaskara Boddakayala, David J. Pfeiffer

Patent number: 11011790Abstract: An exemplary battery assembly includes, among other things, battery cells distributed along an axis and disposed on a base. A bracket extends axially along a side of the battery cells. A plate extends from a first side to an opposing, second side of the battery cells. A retention flange of the plate is held between the bracket and the base. An exemplary method of retaining includes holding battery cells relative to a base using a bracket extending along a side of the array, and positioning a retention flange of a plate between the bracket and the base. A primary portion of the plate is disposed along an axial end of the array.Type: GrantFiled: March 17, 2017Date of Patent: May 18, 2021Assignee: Ford Global Technologies, LLCInventors: Juil Yum, Kimberley King, Rajaram Subramanian, Saravanan Paramasivam, David J.

Patent number: 10431787Abstract: A battery pack retention assembly includes, among other things, a conforming bracket that secures a battery array within a battery pack. The conforming bracket includes platforms that flexes as the conforming bracket is secured. The flexing facilitates aligning an area of the conforming bracket with a thermal exchange plate. A battery pack retention method includes, among other things, flexing a conforming bracket to reduce a gap between the battery array and a thermal exchange plate. The flexing occurs when securing a battery array to within a battery pack.Type: GrantFiled: August 18, 2017Date of Patent: October 1, 2019Assignee: Ford Global Technologies, LLCInventors: Shamsuddin A. Syed, Saravanan Paramasivam, Rajaram Subramanian, David J. Pfeiffer
