Electric vehicles (EVs) represent a pivotal shift in the automotive industry, offering a sustainable alternative to traditional gasoline-powered vehicles. Central to their operation are lithium-ion batteries, which are favoured for their high energy density and long lifespan. Ensuring thermal stability during battery pack operation is crucial for both safety and efficiency. To enhance heat transfer within the battery pack, various encapsulants are employed. This study utilizes simulation to investigate the thermal performance of a 3.072kWh, 51.2V, 60Ah battery pack composed of 6Ah 32700 LFP cells, encapsulated with commercially available materials such as polyurethane (PU) foam, silicone, and silicone-modified epoxy under 1C and 2C discharge conditions. The findings show that, at 1C and 2C discharge rates, respectively, the battery pack potted with silicone attains a maximum temperature that is 2.57°C and 3.84°C lower than the pack simulated with air. Additionally, silicone-modified epoxy facilitates 1.92 times greater heat transfer in the battery pack compared to the pack without encapsulant at 1C, at 2C the heat transfer is 2.07 times higher. While encapsulants with higher thermal conductivities result in lower peak temperatures, they also exhibit a higher temperature gradient across the battery. The findings indicate that as the thermal conductivity of the encapsulant increases, the rate of improvement in the battery pack's heat transfer capabilities tends to decrease.
