The following specification particularly describes the invention and the manner in which it is to be performed.

FIELD OF INVENTION
[0001] Embodiments of a present disclosure relate to battery pack, and more particularly to a Support structure for battery cells in a battery pack.
BACKGROUND
[0002] In order to obtain better power outputs in hybrid or electrical vehicles, electrochemical cells or lithium ion batteries are used and they are often connected either in series or parallel arrangements. In a conventional or a standard battery pack, battery packs include cell holders which are constructed to hold the battery cells in place. Holding the set of individual batteries or the individual battery cells together while isolating battery cells from nearby components in order to impart longevity and keep their functionality constant, battery holders are being used. However, a slight movement in the battery pack leads to misplacement of the battery cells as the conventional battery pack lacks to provide rigid support and structural requirements for the battery cells in the battery pack. Also, the conventional battery pack has limited features in order to meet the functional requirements of the battery pack. Such limitations make the battery pack assembly more complex for mechanical electrical and thermal components to sync with the battery pack. Henceforth, such standard battery packs lack the structural support requirement of the battery pack along with the compactness and flexibility. Such lack of structural support requirement and flexibility makes the standard battery pack less reliable and hence less efficient.
[0003] In a conventional battery or standard battery pack there is a cell holder which holds the electrochemical battery cell or lithium ion battery cells in place. The aforementioned cell holder does not offer excellent protection when the vehicle is set into motion in the dynamic cases and there is a misplacement of battery cells reported due to this slight movement. The conventional battery pack lacks a rigid structure and does not provide firm support to the associated unit in the battery pack. Also, the conventional battery pack has limited features in order to meet the functional requirements of the battery pack. Such limitations make the battery pack assembly more complex for mechanical electrical and thermal components to sync with the battery pack. standard battery packs lack the structural requirement of the battery pack along with compactness and flexibility. Such lack of structural requirement and flexibility makes the standard battery pack less reliable and hence less efficient. In addition, the battery holder must be efficient for cooling and heat dissipation. However, the standard battery pack while providing an arrangement for cooling and heat dissipation misses out on rigidity and firm structural support.
[0004] Hence there is a need for an improved support structure for battery cells in a battery pack to address the aforementioned issues.
PROBLEM TO BE SOLVED BY THE INVENTION
[0005] In conventional battery packs, there is a limitation in the support structures. They offer limited heat dissipation and there is always a chance of misplacement of battery cells when the electrical vehicles are moving from one place to another.
[0006] In the conventional battery packs the support structures are missing and there is limited provision to hold the apparatus. In such cases, these structure does not provide enough rigid support to the associated units
[0007] In Conventional battery packs, the support structures are complex, and it is cumbersome to assemble the parts. The support structures may harm the printed circuit board in such cases when the other components interact with the battery unit and in such cases it is said to be hazardous and unprotected to hold the members in the battery pack thereby resulting in damages to the battery packs
[0008] Thus, another objective of the present invention is to address the issues involving heat dissipation and compactness to the battery pack. To be precise, the present invention apparatus is designed to work in both static and dynamic cases i.e. hybrid or electric vehicles are subjected to motion or at rest.
