Abstract - Even though India has seen many advancements
increase their temperatures. This increase in temperature has two different effects on the batteries. The beneficial effect is that, by increasing the temperature, Li-ion batteries work more efficiently and their performance becomes better. On the other hand, the unfavorable effect is that, they are closer to thermal runaway that decreases their reliability because of probable explosion [2].
in regards to Electric Vehicles, one of the main issues Indian EVs are facing is dealing with the temperature irregularities within the battery pack, effective cooling systems and sudden fires to batteries. Though adapting to new techniques is essential, cost cutting, compactness of the system and optimal weight of the battery should be looked after as well. A battery thermal management system with phase change material with silica, aluminum fins and perforated slots is developed which effectively improves the battery working condition. An intricate system based on multipurpose dry chemical fine powder, which would act on extreme conditions of fire and thus cease the spread of fire and protect the vehicle and the passengers has been developed. An effective battery thermal management system can significantly reduce the chances of an EV battery catching fire, maintain the temperature distribution within the battery pack and thus improve the life of a battery.

1.2 SCOPE Battery Thermal Management with PCM presents more effective thermal performance. The pin fins decrease bulk temperature and improve temperature uniformity. Hybrid cooling effect shows an effective rate of heat dissipation. Provision of vent helps protect battery enclosure.
1. INTRODUCTION Currently in India, Government is enforcing the stringent emission norms for the internal combustion engines driven vehicle. Hence the vehicle manufacturers have to shift their focus to the manufacturing of the electric vehicles. One of the challenges is to develop an efficient battery thermal management system for an electric vehicle. This system also applies to a large number of different vehicle applications, ranging from the compact car to the multi-utility vehicle and from the low-level hybrid vehicle to the entirely electricallydriven vehicle. Thus, it becomes necessary to develop highly efficient energy storage devices for the same. The attraction of the electronics market towards lithium-ion battery as an energy storage device is increasing primarily due to its high energy density, capacity, long cycle life and low self-discharge rate [1].
2. MATERIAL & EXPERIMENTAL TECHNOLOGIES In response to safety concerns surrounding OLA S1 PRO batteries, a scaled-down analysis has been undertaken, with data representing 1/20th of the battery pack. This deliberate reduction aims to facilitate controlled testing and evaluation, given reported incidents of the original batteries exhibiting safety issues, including a notable risk of catching fire. The consideration of data of 1/20TH of the OLA S1 PRO battery pack is as follows: The number of battery cells connected in series N cs [-] in a string is calculated by dividing the nominal battery pack voltage Ubp [V] to the voltage of each battery cell Ubc [V]. The number of strings must be an integer. Therefore, the result of the calculation is rounded to the higher integer.
Li-ion batteries are very sensitive to the temperature. Inside these batteries, during charge and discharge processes, like any rechargeable batteries, heat is generated that causes to
