Embodiment Construction
[0029] refer to Figure 1 to Figure 5 , provides a battery system 10 according to an exemplary embodiment. The battery system 10 includes a thermally conductive base member 20 , a heat transfer member 22 and a battery module 24 . An advantage of the battery system 10 is that the battery system 10 utilizes the heat transfer member 22 disposed directly against the ends of the pouch cells of the battery module 24 without having to use heat sinks disposed between the pouch cells to dissipate heat from the pouch cells. The thermal energy of the battery cells is transferred to the thermally conductive base member 20 .
[0030] refer to figure 2 and Figure 5 , the thermally conductive base member 20 is provided to conduct thermal energy from the heat transfer member 22 to the fluid flowing through the thermally conductive base member 20 . The thermally conductive base member 20 includes an outer housing 40 , an inlet member 42 and an outlet member 44 . The outer housing 40 has...

Abstract
The invention provides a battery system. The battery system includes: a heat conduction base member; a heat transfer member on which the heat transfer member is located; and a battery module having a first pouch-shaped battery unit, wherein the heat transfer member includes a first arc-shaped surface, The second arc-shaped surface and the first groove, the first groove is located between the first arc-shaped surface and the second arc-shaped surface and extends to the heat transfer member, the first pouch type battery unit includes a combination of the first end and the second The first outer casing with two ends, the first end of the first outer casing includes a first extension, the first arc-shaped end surface and the second arc-shaped end surface, the first extension of the first outer casing includes a first extension One end and the second end, the first arc-shaped end face of the first outer shell extends from the first end of the first extension of the first outer shell, and the second arc-shaped end face of the first outer shell extends from the first outer shell The first end of the first extension part of the casing extends and is spaced apart from the first arc-shaped end surface of the first outer casing, and the first pouch-type battery unit is directly located on the heat transfer member, so that the second pouch-type battery unit of the first pouch-type battery unit An extension part is located in the first groove of the heat transfer member, the first extension part of the first outer casing is in direct contact with the heat transfer member, and the first arc-shaped end surface and the second arc-shaped end surface of the first pouch battery unit directly on each of the first and second arcuate surfaces of the thermal interface member.
Description
technical field [0001] This application claims priority and benefit to US Patent Application No. 15 / 044,296, filed February 16, 2016, the disclosure of which is incorporated herein by reference in its entirety. [0002] The invention relates to a battery system. Background technique [0003] Conventional battery systems should use additional intermediate components for transferring thermal energy from the battery cells to cooling components. Therefore, the conventional battery system has a problem of increased volume and weight of the battery module. Furthermore, it is difficult to assemble battery modules using conventional battery cell systems. [0004] The present inventors have recognized a need for an improved battery system that utilizes a thermal interface member in direct contact with the ends of the pouch-type battery cells of a battery module to transfer heat from the pouch-type battery cells to Thermal energy is transferred to the thermally conductive base memb...
