     FIELD 
     The present disclosure relates generally to a vehicle frame assembly, and more particularly to a vehicle frame assembly including a power supply tray. 
     BACKGROUND 
     This section provides background information related to the present disclosure and is not necessarily prior art. 
     Conventional vehicle frames often include two or more side members extending along a length of the vehicle, and two or more cross members extending between the side members and along a width of the vehicle. The side members and cross members are often formed from steel, or another suitably strong and durable material, to support, and provide protection for, the vehicle&#39;s components and occupants. For example, the side members or cross members may be constructed from a material that exhibits sufficient strength and durability to support a power supply, such as a battery or a battery pack assembly. In this regard, a conventional vehicle frame often includes one or more brackets coupled to the side members or the cross members for attaching a battery pack or other vehicle component to the frame assembly. Often, the manner of assembling the various components to the vehicle frame may not provide the desired level of support and protection for each of the components. Accordingly, while known vehicle frame assemblies have proven suitable for their intended purposes, there remains a need for improvement in the pertinent art. 
     SUMMARY 
     This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.

     DETAILED DESCRIPTION 
     Example configurations will now be described more fully with reference to the accompanying drawings. Example configurations are provided so that this disclosure will be thorough, and will fully convey the scope of the disclosure to those of ordinary skill in the art. Specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of configurations of the present disclosure. It will be apparent to those of ordinary skill in the art that specific details need not be employed, that example configurations may be embodied in many different forms, and that the specific details and the example configurations should not be construed to limit the scope of the disclosure. 
     The terminology used herein is for the purpose of describing particular exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. Additional or alternative steps may be employed. 
     When an element or layer is referred to as being “on,” “engaged to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly on, engaged, connected, attached, or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. 
     The terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections. These elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example configurations.

The fifth insulation member  70 - 5  may traverse the void  34  and extend from the first cross member  30  to the second cross member  32  and from the first longitudinal member  26  to the second longitudinal member  28 . 
     With reference to  FIGS. 2 and 4-6 , the frame assembly  12  may further include one or more cooling members  72 - n  (e.g., conduits) and one or more busbars  74 - n . In some implementations, the cooling member(s)  72 - n  and the busbars  74 - n  may be coupled to, or otherwise supported by, the frame assembly  12  (e.g., to one or more of the first or second cross members  30 ,  32  or the first or second longitudinal members  26 ,  28 ) to transfer heat or electricity, respectively, from the power supply assembly  18 , as will be described in more detail below. For example, as illustrated in  FIG. 4 , the cooling members  72 - n  and the busbars  74 - n  may extend in a direction substantially parallel to the first and second longitudinal members  26 ,  28 , and from the first cross member  30  to the second cross member  32 , such that the cooling members  72 - n  and the busbars  74 - n  traverse the void  34 . In some implementations, each busbar  74 - n  includes a plurality of connectors  76  for coupling each busbar  74 - n  to a power supply assembly  18  for electrical communication therewith. Similarly, each cooling member  72 - n  may include a plurality of connectors  77  (e.g., inlets or outlets) for coupling each cooling member  72 - n  to a power supply assembly  18  for fluid communication therewith. 
     As illustrated in  FIGS. 2-6 , the power supply assembly  18  may include a tray  78 , a plurality of insulation members  80 - n , a plurality of batteries  82 - n , and one or more dividers  83 . The tray  78  may include a first longitudinal wall  84 , a second longitudinal wall  86 , a first lateral wall  88  extending from the first longitudinal wall  84  to the second longitudinal wall  86 , a second lateral wall  90  extending from the first longitudinal wall  84  to the second longitudinal wall  86 , and a bottom wall  92  extending from the first longitudinal wall  84  to the second longitudinal wall  86  and from the first lateral wall  88  to the second lateral wall  90 . In some implementations, the first longitudinal wall  84  is substantially parallel to the second longitudinal wall  86 , and the first lateral wall  88  is substantially parallel to the second lateral wall  90 , such that the first and second longitudinal walls  84 ,  86  and the first and second lateral walls  88 ,  90  define a substantially rectangular shape, and the first and second longitudinal walls  84 ,  86 , the first and second lateral walls  88 ,  90 , and the bottom wall  92  collectively define a chamber  94 . 
     With reference to  FIGS. 2 and 5 , one or more of the first or second longitudinal walls  84 ,  86  or the first or second lateral walls  88 ,  90  may include flange  98 . As illustrated, in some implementations the flange(s)  98  extend inwardly from an upper end of the first and second longitudinal walls  84 ,  86 . In this regard, the one or more flange  98  coupled to an upper end of the first longitudinal wall  84  may extend toward the second longitudinal wall  86 , while the one or more flange  98  coupled to an upper end of the second longitudinal wall  86  may extend toward the first longitudinal wall  84 , such that the flange(s)  98  coupled to the first longitudinal wall  84  are substantially parallel to, and coplanar with, the flange(s)  98  coupled to the second longitudinal wall  86 .

     Each battery  82 - n  may include one or more electrical connectors  102  and one or more fluid connectors  104 . For example, as illustrated in  FIG. 4 , in some implementations, each battery  82 - n  includes two electrical connectors  102  (e.g., a positive terminal and a negative terminal) and two fluid connectors  104  (e.g., an inlet and an outlet). 
     As illustrated in  FIGS. 3-6 , in an assembled configuration, the batteries  82 - n  may be disposed within the chamber  103  such that the first, second, third, and fourth insulation members  80 - 1 ,  80 - 2 ,  80 - 3 ,  80 - 4  substantially surround at least a portion of each battery  82 - n . In some implementations, the dividers  83  are disposed between one or more of the batteries  82 - n . For example, each divider  83  may be disposed between at least two of the batteries  82 - n  and extend between the first and second insulation members  80 - 1 ,  80 - 2 . In particular, the dividers  83  may extend from the first insulation member  80 - 1  to the second insulation member  80 - 2 . The power supply assembly  18  may be assembled relative to the frame assembly  12  such that the plurality of batteries  82 - n  are disposed within the void  34 . In this regard, in the assembled configuration, at least a portion of the batteries  82 - n  may be disposed between the first and second cross members  30 ,  32  and the first and second longitudinal members  26 ,  28 , such that the insulation members  70 - n  collectively surround at least a portion of each of the plurality of batteries  82 - n.    
     In some implementations, the power supply assembly  18  is coupled to the frame assembly  12  such that a first portion (e.g., a lower portion) of the batteries  82 - n  is surrounded by the tray  78  and a second portion (e.g., an upper portion) of the batteries  82 - n  is surrounded by the frame assembly  12 . For example, the first and second longitudinal walls  84 ,  86  of the tray  78  may be coupled to the first and second longitudinal members  26 ,  28 , respectively, and the first and second lateral walls  88 ,  90  may be coupled to the first and second cross members  30 ,  32 , respectively. In particular, the flange(s)  98  may be coupled to the first, second, third, or fourth lower walls  40 ,  48 ,  56 ,  66  of the first or second longitudinal members  26 ,  28  or the first or second cross members  30 ,  32 , respectively, with a bolt, rivet, screw, or other suitable fastening mechanism, such that the insulation members  70 - n ,  80 - n  collectively surround the batteries  82 - n . In this assembled configuration, the batteries  82 - n  may be coupled to the cooling members  72 - n  and/or the busbars  74 - n  to transfer heat or electricity, respectively, from the batteries  82 - n . For example, one of the connectors  102  (e.g., a positive terminal) of one or more of the batteries  82 - n  may be coupled to one of the connectors  76  of a first busbar  72 - 1 , while another of the connectors  102  (e.g., a negative terminal) of one or more of the batteries  82 - n  may be coupled to one of the connectors  76  of a second busbar  72 - 2  to transfer electricity from the batteries  82 - n  to another component of the vehicle  10 . Similarly, one of the connectors  77  (e.g., an inlet) of a first cooling member  72 - n  may be coupled one of the connectors  104  (e.g., an outlet) of a battery  82 - n , while one of the connectors  77  (e.g., an outlet) of a second cooling member  72 - n  may be coupled to another connector  104  (e.g., an inlet) of the battery  82 - n  to transfer heat from the battery  82 - n  to the atmosphere surrounding the batteries  82 - n.    
     In some implementations, a plurality of the batteries  82 - n  are electrically coupled to one another in a series circuit arrangement. In some implementations, a plurality of the batteries  82 - n  are electrically coupled to one another in a parallel circuit arrangement. In some implementations, a first plurality of the batteries  82 - n  are electrically coupled to one another in a series circuit arrangement, and a second plurality of the batteries  82 - n  are electrically coupled to one another in a parallel circuit arrangement. For example, the first plurality of batteries  82 - n  may be electrically coupled to one another in a series circuit arrangement, and electrically coupled to one or more other batteries  82 - n  in a parallel circuit arrangement. 
     The frame assembly  12  and the power supply assemblies  18  can help to provide a strong, durable system for supporting one or more batteries  82 - n  during operation of the vehicle  10  and to ensure an efficient, durable system for providing electricity to the motor  16  or other component of the vehicle  10 . The incorporation of more than one power supply assembly  18 , as illustrated in  FIG. 1 , can allow the system to satisfy various electrical energy requirements of multiple vehicles  10  and/or customers. In particular, the vehicle  10  can be customized to include a quantity of power supply assemblies  18  that is satisfactory for the unique electrical energy requirements of the vehicle  10 .
