In preparation for FSAE Australasia 2024, the Arjuna EV UGM team faces several challenges. A major hurdle is the increasingly tight timeline due to delays in shipping the car from Australia to Indonesia, as many components are still on the car. This situation forces the team to maximize simulation time and meticulously plan the manufacturing process. Nevertheless, the team views these challenges not as obstacles but as opportunities to be tackled with enthusiasm and creativity.

Not only operational difficulties, electronic manufacturing difficulties also held us back, some of the difficulties were the placement of cables for High Voltage which was complicated because we had difficulty in finding the right components with the specifications we wanted. Difficulties regarding air duct & thermal are difficulties that we must try to overcome.

The air duct cooling system comprises components fabricated using 3D printing technology, utilizing ABS filament reinforced with Carbon Fiber for enhanced strength and durability. Resin is employed as a hardener to further reinforce the structure. The system consists of one main plenum, which is subdivided into four pipes to facilitate airflow distribution to each segment of the battery box.

Each pipe segment is designed to accommodate an airflow rate of 0.034 m³/s, with an inlet velocity of 10 m/s. This specification ensures that an adequate volume of air is delivered to each battery segment to facilitate efficient cooling.

The use of ABS filament with Carbon Fiber reinforcement provides the necessary structural integrity to withstand the rigors of continuous operation and temperature variations within the battery compartment. Additionally, the application of resin as a hardener enhances the overall durability and longevity of the system, ensuring reliable performance over an extended period
