- the second sheet portion 532 is on the heat conductive layer 88 and is in direct contact.
- the first sheet portion 530 is positioned to face the battery cells 450 and 452.
- the thermal energy from the battery cells 450, 452 passes through the first sheet portion 530 to the second sheet portion 532 so that the refrigerant flowing through the cooling plate assembly 22 absorbs the thermal energy. Conduction and further conduction to the cooling plate assembly 22. As a result, the cooling plate assembly 22 maintains the battery module 24 within the desired temperature range.
- the end support plates 40, 42 are coupled to the first and second ends of the support frame 20, respectively, and extend substantially perpendicular to the support frame 20.
- the battery modules 24, 26, 28 are sandwiched between the end support plates 40, 42.
- the upper support plates (so that the battery modules 24, 26, 28 are firmly fixed between the upper support plates 44, 46, the lower support plates 40, 42, and the cooling plate assembly 22). 44, 46 are coupled between upper ends of the lower support plates 40, 42.
- the battery pack provides a significant advantage over other battery packs.
- the battery pack uses a cooling plate assembly including first and second corrugated support members that prevent collapse of the cooling plate assembly when a vacuum is applied to the cooling plate assembly.
- the battery pack according to the present invention includes a cooling plate assembly, wherein the cooling plate assembly has improved internal support components to prevent collapse by the internal support components when a vacuum is applied to the cooling plate assembly. , Has the effect of maintaining the battery module within the preferred temperature range.
