Embodiment Construction

[0025] refer to Figure 1-13 , the battery pack 10 according to the exemplary embodiment is provided. The battery pack 10 includes a cooling plate 20 and battery modules 40 , 42 , 44 in accordance with an exemplary embodiment. An advantage of the cooling plate 20 is that the cooling plate 20 has a flow path pattern 370 (shown in Figure 8 ) and flow path pattern 372 (shown in Figure 8 ), the flow path pattern 370 is shaped and sized so that the battery module 40 is along the plane 1000 (shown in image 3 Middle) the temperature of at least the first half of the cross-sectional area cut off is maintained within one degree Celsius of the first temperature level, and the flow path pattern 372 is shaped and adjusted in size so that at least The temperature of the second half is maintained within one degree Celsius of the first temperature level.

[0026] refer to Figure 4-10 A cooling plate 20 is provided to cool the battery modules 40 , 42 , 44 using refrigerant flowing th...

Abstract

A battery pack having a battery module and a cooling plate is provided. The battery pack has a bottom surface and a first plane extending through the battery modules parallel to the bottom surface. The cooling plate has a base pan and a top plate coupled together and extending along a longitudinal axis. The bottom surface of the battery module is disposed on the top plate. The chassis has a first cooling region having first and second flow path patterns therein that receive refrigerant therethrough. The first flow path pattern and the second flow path pattern are shaped and sized to maintain the temperature of the first half and the second half of the cross-sectional area of ​​the battery module, respectively, within one degree Celsius of the first temperature level.

Description

technical field [0001] The present invention relates to batteries. [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 432,954, filed December 12, 2016, and U.S. Patent Application No. 15 / 446,733, filed March 1, 2017, the entire contents of which are hereby incorporated by reference into this article. Background technique [0003] The battery pack has battery modules therein. A problem with known battery packs is that the various cooling methodologies utilized to cool the battery pack have not been able to maintain the temperature of the cross-sectional area of ​​the battery module within one degree Celsius of the desired temperature level during operation, wherein the battery The cross-sectional area of ​​the module is parallel to the bottom surface of the battery module. During operation, the centrally located battery cell in the battery module has a temperature that is more than one degree Celsius greater than the temperature of the ...
