An automotive lithium-ion battery pack is a device comprising electrochemical cells interconnected in series or parallel that provide energy to the electric vehicle. The battery pack embraces different systems of interrelated subsystems necessary to meet technical and life requirements according to the applications (Warner, 2015).
However, their performance is notably compromised by excessive temperatures, a factor intricately linked to the batteries’ electrochemical properties. To optimize lithium-ion battery pack performance, it is imperative to maintain temperatures within an appropriate range, achievable through an effective cooling system.
The findings affirm that the discharge rate is the most influential parameter shaping the thermal behavior of lithium-ion battery packs. The thermal properties of a battery pack are greatly affected by its electrical setup, standing as the second most influential factor.
Discharge rate showed the highest contribution followed by electrical configuration. Discharge rate impacts T max by 44 % and ΔT max by 58.2 %. Proposed optimum condition for thermal performance of LIB pack. Lithium-ion batteries are increasingly preferred for energy storage, particularly in Electric Vehicles (EVs).
However, previous research acknowledges that different vibration tests proposed in standards and regulations for lithium-ion battery packs vary substantially in the levels of energy and frequency range (Kjell and Lang, 2014) so there is still a big challenge to emulate a test that represents the real working condition of electric vehicles.
Lastly, existing research overlooks the impact of electrical configuration on thermal properties, particularly in series-connected lithium-ion battery setups where voltage fluctuations and state of charge variations pose safety and reliability concerns.
