Embodiment Construction

[0038] Exemplary embodiments will now be described more fully hereinafter with reference to the accompanying drawings; however, these embodiments may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0039] In the drawings, the dimensions of layers and regions may be exaggerated for clarity of illustration. It will also be understood that when a layer or element is referred to as being "on" another element, it can be directly on the other element, or intervening elements may also be present. In addition, it will also be understood that when an element is referred to as being "between" two elements, it can be the only element between the two elements, or one or more intervening elements may also be present. Like reference numerals refer to like eleme...

Abstract

A battery pack and a cooling system for a battery pack that includes a plurality of battery cells, the battery pack including a plurality of battery cells; a first refrigerant circulation pipe; and a second refrigerant circulation pipe adjacent to the first refrigerant circulation pipe, wherein the first refrigerant circulation pipe is configured to direct a refrigerant along a first circulation pathway, the second refrigerant circulation pipe is configured to direct the refrigerant along a second circulation pathway counter to the first circulation pathway, and at least one of the first refrigerant circulation pipe and the second refrigerant circulation pipe is in thermal co-operation with the battery cells.

Description

technical field [0001] Embodiments relate to a battery pack and a cooling system for a battery pack. Background technique [0002] Unlike primary batteries, which are not rechargeable, secondary batteries are rechargeable and dischargeable. Such a secondary battery can be used in a battery pack formed by electrically connecting a plurality of battery cells to each other, so that the secondary battery can be used in applications such as electric vehicles and uninterruptible power supply. [0003] Each battery cell of the battery pack may be heated when being repeatedly charged and discharged. If heat generated due to repeated charging and discharging is not cooled in the battery pack, the performance of each battery cell may decrease. Also, the heat generated by each battery cell can degrade the performance of the battery pack as a whole. Contents of the invention [0004] Embodiments relate to a battery pack and a cooling system for a battery pack. [0005] At least o...
