Abstract

Pada mobil listrik terdapat komponen utama yaitu baterai, sebagai sumber energi utama. Agar baterai memiliki daya tahan yang kuat harus dilakukan pendinginan secara optimal. Untuk itu dalam proyek akhir ini dirancang sistem kendali untuk pendingin baterai pada bus listrik di STP Otomotif ITS yang memanfaatkan aliran dingin dari peltier dan kipas untuk pendinginan pada lingkungan baterai pack pada bus listrik. Fokus dari penelitian ini adalah simulasi software proteus sistem kendali pendingin otomatis untuk baterai pack bus listrik di STP Otomotif ITS. Sistem memanfaatkan kombinasi modul peltier 12V, heat sink, dan kipas DC 12V sebagai unit pendingin aktif. Sensor suhu LM35 berfungsi sebagai umpan balik dalam sistem kendali closed-loop untuk menjaga suhu lingkungan baterai pada rentang optimal 25–40°C. Simulasi sistem kendali dilakukan menggunakan software proteus 8 untuk memvalidasi kinerja sistem. Hasil menunjukkan sensor LM35 memiliki akurasi linier 10 mV/°C. Sistem mampu merespons dengan menurunkan suhu dari 40,08°C ke 20,04°C dalam 120 detik (laju pendinginan rata-rata -0,167°C/detik). Analisis termodinamika menghasilkan laju perpindahan panas konveksi sebesar 66,11 W, kalor total konveksi 9,92 kJ dalam 150 detik, dengan efektivitas sistem 97,2% dan efisiensi 91,8%. Simulasi membuktikan sistem yang dirancang efektif mencegah overheating, mendukung keandalan operasional bus listrik, dan sejalan dengan tujuan Perpres No. 55 Tahun 2019 tentang kendaraan listrik ramah lingkungan.

Electric cars have a main component, namely the battery, as the main source of energy. In order for the battery to have strong durability, optimal cooling must be carried out. For this reason, this final project designed a control system for battery cooling on electric buses at the ITS Automotive Engineering Department, which utilizes cold airflow from Peltier and fans to cool the battery pack environment on electric buses. The focus of this research is the Proteus software simulation of an automatic cooling control system for the battery pack of electric buses at ITS Automotive Engineering. The system utilizes a combination of a 12V Peltier module, heat sink, and 12V DC fan as an active cooling unit. The LM35 temperature sensor functions as feedback in a closed-loop control system to maintain the battery environment temperature within the optimal range of 25–40°C. The control system simulation was performed using Proteus 8 software to validate the system's performance. The results show that the LM35 sensor has a linear accuracy of 10 mV/°C. The system is capable of responding by lowering the temperature from 40.08°C to 20.04°C in 120 seconds (average cooling rate of -0.167°C/second). Thermodynamic analysis resulted in a convective heat transfer rate of 66.11 W, total convective heat of 9.92 kJ in 150 seconds, with a system effectiveness of 97.2% and efficiency of 91.8%. The simulation proves that the designed system effectively prevents overheating, supports the operational reliability of electric buses, and aligns with the objectives of Presidential Regulation No. 55 of 2019 on environmentally friendly electric vehicles
