  • Patent number: 10886517
    Abstract: Electrified vehicles such as hybrid electric vehicles (HEV's), plug-in hybrid electric vehicles (PHEV's), battery electric vehicles (BEV's), or fuel cell vehicles differ from conventional motor vehicles in that they are powered by one or more electric machines (i.e., electric motors and/or generators) instead of or in addition to an internal combustion engine. High voltage current for powering these types of electric machines is typically supplied by a high voltage traction battery system having one or more battery cells that store energy.

  • Patent number: 9178196
    Abstract: A battery assembly having a plurality of battery modules capable of powering a traction motor of a vehicle. First and second end frames are provided on the battery modules. A plurality of battery cells is disposed between the first and second end frames. The first end frame of one of the battery modules has a first pocket. The second end frame of an adjacent battery module has a second pocket. The first and second pockets are aligned when the battery assembly is assembled to define a receptacle. A thermistor is disposed in the receptacle. The thermistor extends through the first pocket of the first end frame and at least partially into the second pocket of the second end frame.

  • Patent number: 8968912
    Abstract: A battery module assembly and method of assembling a battery. The battery module assembly includes a plurality of modules in which a plurality of battery cells are preassembled. The modules are compressed by end plates that are held together under compression by a plurality of linking members. The end plates may include a protrusion that applies pressure to the central portion of the battery cells within the modules. The central portion of the end plates may be partially spherical, partially cylindrical or a flat surface.
