  • Patent number: 9196878
    Abstract: A battery assembly includes a plurality of stacked battery cartridges. Each battery cartridge includes a first receptacle unit, a battery cell stack, and a second receptacle unit positioned within first receptacle unit. The battery cell stack includes a first battery cell, a second battery cell, and a foam layer interposed between the first battery cell and the second battery cell. The battery cell stack is positioned within the first receptacle unit, with the second receptacle unit compressing the battery cell stack. The battery module assembly also includes a receiving assembly that holds the plurality of battery cartridges.

  • Patent number: 9054361
    Abstract: A method of assembling a battery module assembly includes a step of preparing a plurality of battery cell stacks. Each battery cell stack is constructed by positioning a pre-compressed foam unit interposed between a first battery cell and a second battery cell. Each battery cell stack is positioned in a receiving frame. After such positioning, the pre-compressed foam unit of each battery cell stack is expanded.

  • Patent number: 9050898
    Abstract: A battery module includes two or more battery cells and a continuous wave fin disposed between the battery cells. The construction of the wave fin is generally one-piece such that fewer parts are needed to form the battery module. In a preferred form, the wave fin is made from a high thermal conductivity material to promote removal of heat generated by the batteries during their operation. Portions of the wave fin not in direct contact with the battery cells may be placed in direct contact with a heat sink to help remove excess heat from the module. Expansion units or related additional structure may be placed, along with the various battery cells, between the generally serpentine-shaped wave fin to provide uniformity in cell spacing. A method of making one or more battery modules is also described.

  • Patent number: 8292572
    Abstract: A blower motor assembly for use in a heating, ventilation and air-conditioning system of a vehicle and a method of diverting water are disclosed. The blower motor assembly may include a motor housing, configured to surround internal components of the blower motor assembly, and including a cooling channel/air intake opening. The blower motor assembly may also include a motor support flange extending radially outward from the motor housing and having an upward facing surface, and at least one water diversion vane extending upward from the upward facing surface and extending radially outward in an arcuate shape to divert water off of the flange.
