“…For a discussion of current dumping in battery packs and efforts to minimize its occurrence in CID protected parallel cell battery packs have been provided by Plunkett. 17 During an internal short circuit, all the heat generated in a Li-ion cell flows into the cell with the result that the cell temperature raises very quickly to extremely high values. The safety devices in the cell, including the pressure release valve, are unable to respond quickly to the heat generated in an internal short circuit.…”

Lithium-Ion batteries are highly successful high-energy-density commercial energy sources used to run consumer devices such as cellphones, E-bikes, hoverboards, laptops, tablets, and medical equipment. They are safe if produced with attention paid to the selection of materials and to the manufacturing methods used for their production and quality control processes. However, safety hazards arising from rare manufacturing defects have given them notoriety as devices to be handled with utmost care. This manuscript provides an account of the safety-related chemistry of Li-ion batteries and the processes used to manufacture and utilize them safely.

“…The market adoption of energy‐efficient and eco‐friendly EVs is increasing and there is more potential if batteries are more energy efficient, travel longer, and cheaper thus to do so battery cooling system to maintain temperatures in the optimum range of 15°C to 35°C 9,10 is essential for lithium‐ion (Li‐ion) batteries in EVs and hybrid EVs (HEVs) extends service life and ensures operational safety. During vehicle operation, considerable heat is generated in the battery that must be removed.…”

The battery pack is one of the crucial components in the creation of an electric car. Thus, its optimal and efficient functioning is of prime importance. Several issues are generated due to battery heating which may be fatal and can cause severe issues. The battery cooling system is one of the most effective ways to keep the battery pack at the ideal temperature for lithium‐ion cells to function properly. This article mainly focuses on MATLAB Simulink simulation‐based novel battery cooling system design using Nanofluids. In this simulation study, the employed nanofluids are compared mostly to ethylene glycol. The simulation findings demonstrated that employing nanofluid as the coolant cools the battery pack more quickly than using ethylene glycol. It was found that ethylene glycol can cool the battery pack within 480 seconds while with the use of nanofluids the battery pack was cooled in just 150 seconds considering the temperature cooling from 40°C to 25°C. The effective and fast cooling of Nanofluids is due to the higher value of thermal conductivity of the fluid which plays a major role in heat transfer. Thus, fluid properties mainly thermal conductivity must be focused upon and % concentration of nanoparticles in the base fluid must be increased to get more effective cooling.
