Description:FIELD OF THE INVENTION
Embodiments of a present disclosure relate to battery packs, and more particularly to an energy density of battery pack with an improved battery cells arrangement.

BACKGROUND OF THE INVENTION
With increasing technological demands, the automotive industrial growth is considered as one among the fastest. Transportation remains a key factor for users, which has created depletion of natural resources. Such situations gave rise to introducing ways to design more eco-friendly vehicles. Vehicles which are environmentally friendly remain attractive and meeting out demands of users remains as a fundamental aspect in industry. In the conventional battery packs the lithium-ion battery cells are displaced in linear fashion and such arrangement results in minimalistic energy efficiency. Also, these cell arrangements are either closely or very tightly packed.

Further, in conventional battery packs with spatial arrangement, even though a greater number of lithium-ion battery cells are included they are not efficient as the system does not meet such huge energy demand. Due to limited calculated space utilization the energy density remains very awry. In cases where the battery cell arrangement is improper or very distorted, it creates more disturbance to other electrical components. This makes heat transfer high thereby overheating the battery packs. Hence, there is a need for an improvised battery cell arrangement and array structure in battery packs to provide better energy transfer and maximize energy density.

PROBLEM TO BE SOLVED BY INVENTION
The poor packing structure and battery cell arrangements create a great deal of unutilized space. In such cases, the accommodation of more battery cells in given space is challenging.

Hence, it is a primary objective of the current invention to accommodate a greater number of battery cells in given space, thereby increasing energy density per unit area by reducing unutilized space.

The misalignment of battery cells and compactness create less energy efficient battery packs with more heat dissipation and more heat transfer within the battery pack.

Thus, it is another objective of the current invention to provide efficiently spaced battery cells in the battery pack to manage thermal heat propagation.

The above-mentioned shortcomings, disadvantages and problems are addressed herein, and which will be understood by reading and studying the following specification.
