The proposed solution involves the systematic integration of graphene nanofluids within the BTMS infrastructure. This includes a comprehensive investigation into optimal nanoparticle concentration, fabrication techniques, and fluid characteristics to achieve effective heat dissipation while preventing the battery from surpassing the critical temperature threshold. Implementing a well-designed BTMS with graphene nanofluids as the cooling medium offers a promising solution to sustain the desired temperature range, ensuring the prolonged and safe operation of lithium-ion batteries in various applications.

The results show considerable improvement in thermal conductivity using the fan system. When the setup runs without nanofluids and no forced convection, the cooling is extremely slow. Using the fan system with nanofluids improves the overall efficiency but increases the rate at which the temperature drops faster with nanofluids. When using only methanol, it takes about 1 hour to cool the system from 70°C to 37°C, which is an acceptable temperature range. Adding fans to the system reduces the time by 64.1%, i.e., it takes 24 minutes to reach 37°C. Using nanofluid instead of methanol increases efficiency by 25%, and the final time is 50 minutes. Using fans with nanofluid cools the system in 23 mins, which is 65% more efficient than using just methanol.
