Abstract

The present disclosure relates to apparatuses for conducting battery heat comprising an active material positioned between a first cover portion and second cover portion, each portion comprising a thermal conductive material and protection material connected to the thermal conductive material. Also included are systems for conducting heat includes a plurality of pouch cells each comprising an active material positioned between a first cover portion and second cover portion and a plurality of frames, at least one frame positioned between each of the plurality of pouch cells. Finally included are methods, for assembling a pouch cell structure for use in conducting battery heat, comprising constructing a pouch cell assembly by alternating a sequence of pouch cells and frames; positioning a first contact edge of each of pouch cell proximal to a first heat sink and a second contact edge of each pouch cells proximal to a second heat sink opposite the first contact edge; and connecting the first heat sink to the first contact edge of each of the plurality of pouch cells and connecting the second heat sink to the second contact edge of each of the plurality of pouch cells.

Description

technical field [0001] This technology relates to heat transfer associated with vehicle batteries. More specifically, the technology relates to the use of both pouch battery material and extended pouch battery edges to achieve desired heat transfer. Background technique [0002] Thermal energy (ie, heat) can be dissipated or conducted using pouch batteries. A pouch battery is an electrode assembly containing electrode lead joints that lead the positive and negative terminals to the outside of a sealed flexible case or pouch. Pouch cells are inherently lightweight and flexible due to the absence of a metal case, and are preferred over cylindrical cells for certain applications. [0003] Heat transfer using pouch batteries has a wide range of applications, including grid energy storage, computer hardware, and vehicle batteries. [0004] Attempts have been made to reduce the weight of pouch batteries without changing heat dissipation or conductivity. One attempt is to reduc...
