Abstract

Electric mobility mode could be a great opportunity to reduce emissions from the transportation sector. The future mobility calculator and electric car power demand, developed by Coalition for Urban Transitions and International Energy Agency, respectively, were used to analyze Indonesia’s shifting strategy toward electric mobility. It was shown that going to electric mobility will reduce 90% of Indonesia’s emissions from the transportation sector by the year 2050. Nevertheless, the charging infrastructure must be improved quickly to provide a proper ecosystem for electric mobility. Additionally, the electric vehicle waste management system is urgently needed soon. The success of shifting toward electric mobility not only benefits Indonesia’s environment but also strengthens its international credibility for sustainable development.

Abstract

The electric vehicle (EV) industries have grown; in 2023 EV sales increased by more than 30% compared to 2022. The central issue of this industry is the battery because of the cost and environmental problems.  This makes efficient battery operation and condition imperative. The electric vehicle lithium-ion batteries are highly temperature-dependent for optimal performance and longevity. A cooling system is needed to maintain the temperature of the lithium-ion battery within the optimal temperature range. This study proposes nanofluid cooling based on Cellulose Nanocrystals (CNC) inside the wavy channel tube. Other fluid cooling, such as air and water, are compared. Three-dimensional (3D) transient simulation is performed by varying the cooling fluid and mass flow rate. On the other hand, experiments were conducted to validate the simulation's conformity to the battery module's temperature. The performance of the cooling fluid inside the wavy channel effectively keeps the battery heat dissipation and temperature uniformity. The nanofluid can maintain the temperature of the battery module at its optimal temperature (below 40°C), even with the lowest flow rate (5×10-4 kg/s).
