Abstract
Peningkatan adopsi kendaraan listrik (Electric Vehicle/EV) mendorong perlunya sistem manajemen termal baterai (Battery Thermal Management System/BTMS) yang tidak hanya efisien, namun juga andal dalam menjaga kestabilan suhu kerja baterai lithium-ion. Salah satu pendekatan pasif yang menjanjikan adalah penggunaan Loop Heat Pipe (LHP), yang memanfaatkan mekanisme perpindahan panas dua fase tanpa memerlukan komponen mekanik aktif. Penelitian ini berfokus pada perancangan dan implementasi sistem otomatisasi aliran masuk (flow inlet) pada evaporator LHP guna mengoptimalkan performa termal BTMS. Sistem dirancang dengan pendekatan kontrol loop tertutup berbasis mikrokontroler Arduino Mega 2560, menggunakan sensor suhu RTD PT100 dan modul konversi MAX31865 sebagai elemen umpan balik. Aktuasi aliran dilakukan oleh solenoid valve yang diatur berdasarkan perubahan suhu evaporator. Pengujian dilakukan terhadap distribusi temperatur pada permukaan baterai dummy dan evaporator untuk mengevaluasi efektivitas sistem dalam menjaga suhu operasi dalam rentang optimal (15–35°C). Hasil eksperimen menunjukkan bahwa sistem otomatisasi flow inlet secara signifikan mampu meningkatkan kestabilan distribusi termal dan menurunkan laju deviasi temperatur antar titik, yang pada akhirnya berkontribusi pada peningkatan efisiensi dan keselamatan sistem BTMS berbasis LHP.

The growing adoption of electric vehicles (EVs) necessitates a battery thermal management system (BTMS) that ensures both thermal efficiency and operational reliability, particularly for lithium-ion batteries that are highly sensitive to temperature fluctuations. One promising passive cooling solution is the Loop Heat Pipe (LHP), which utilizes a two-phase heat transfer mechanism without relying on mechanical pumping components. This research presents the design and implementation of a flow inlet otomation system on the LHP evaporator to enhance BTMS performance. A closed-loop control system was developed using an Arduino Mega 2560 microcontroller, incorporating RTD PT100 temperature sensors and the MAX31865 signal conditioning module for accurate feedback acquisition. Flow regulation is achieved through a solenoid valve that responds dynamically to temperature variations in the evaporator. Experimental tests were conducted to assess thermal distribution across a dummy battery module and the evaporator under varying inlet flow configurations. The results demonstrate that the proposed control system effectively maintains battery temperatures within the safe operational range (15–35°C), enhances thermal uniformity, and reduces temperature deviations, thereby improving both the efficiency and safety of the LHP-based BTMS.
