Abstract
Pergerakan menuju sumber energi terbarukan untuk menanggulangi efek rumah kaca dalam program Net Zero Emission (NZE) telah menjadi tujuan global. Pergeseran bensin sebagai bahan bakar fosil menuju baterai lithium pada kendaraan bermotor menjadi salah satu penerapannya. Baterai menjadi komponen utama dalam penyimpanan energi terbarukan dengan efisiensi tinggi. Namun, stabilitas suhu baterai menjadi salah satu perhatian lebih dikarenakan pada baterai dapat timbul thermal runaway yang menghasilkan Heat Release Rate (HRR) sebagai salah satu penyebab kebakaran. Simulasi menggunakan Fire Dynamic Simulator (FDS) pada software Pyrosim diperlukan untuk menganalisis ukuran mesh yang sesuai sehingga nilai kurva HRR dapat mendekati nilai eksperimen. Dengan simulasi berbagai ukuran mesh pada pemodelan mobil listrik berbasis baterai lithium, ukuran mesh yang menghasilkan kurva HRR-waktu paling mendekati model kurva hasil eksperimen dihasilkan pada mesh 0.4 dengan maksimum HRR yang dihasilkan 71700 kW pada detik ke-722.

The movement towards renewable energy sources to mitigate the greenhouse effect within the Net Zero Emission (NZE) program has become a global objective. The shift from gasoline as a fossil fuel to lithium batteries in motor vehicles is one of its implementations. Batteries become a key component in renewable energy storage due to their high efficiency. However, the thermal stability of batteries has become a major concern because thermal runaway can occur in batteries, resulting in a Heat Release Rate (HRR) that can cause fires. Simulations using the Fire Dynamic Simulator (FDS) in Pyrosim software are necessary to analyze the appropriate mesh size so that the HRR curve values can closely approximate experimental values. By simulating various mesh sizes in the modelling of lithium battery-based electric cars, the mesh size that produces the HRR-time curve closest to the experimental curve was found to be 0.4, with a maximum HRR of 7450 kW occurring at the 722-seconds.
