Abstract
Stabilitas temperature merupakan aspek krusial dalam pengoperasian battery pack lithium-ion, khususnya pada sistem penyimpanan energi berbasis photovoltaic (PV). Deviansi dari rentang temperature operasional ideal (24–40 °C) dapat menyebabkan penurunan kapasitas, efisiensi thermal, serta meningkatkan risiko terjadinya thermal runaway. Oleh karena itu, diperlukan sistem management thermal yang adaptif dan efisien, khususnya untuk aplikasi berskala kecil dan off-grid. Penelitian ini bertujuan untuk
merancang dan mengimplementasikan sistem monitoring thermal berbasis peltier dan fan, secara real-time menggunakan microcontroller ESP32 dual-core. Metodologi yang digunakan mencakup perancangan perangkat keras yang terdiri dari sensor temperature sensor arus dan tegangan, serta aktuator termal (peltier dan fan). Sistem dikendalikan melalui pemrograman ESP32 yang memproses data pengukuran berdasarkan kondisi temperature aktual. Tampilan monitoring dilakukan secara real-time melalui HMI. Pengujian dilakukan pada saat dan discharging baterai guna mengevaluasi respons sistem
terhadap perubahan temperature. Hasil pengujian menunjukkan bahwa sistem mampu melakukan monitoring temperatur secara real-time dan menjaga distribusi temperatur battery pack tetap stabil selama proses discharging. Nilai ΔT yang diperoleh berada pada rentang 0,08–0,76 °C, yang menunjukkan bahwa kombinasi modul Peltier dan fan mampu meminimalkan perbedaan temperatur antar titik pengukuran sehingga kondisi termal battery pack tetap terjaga selama proses pengujian.

Temperature stability is a crucial aspect in the operation of lithium-ion battery packs, especially in photovoltaic (PV) based energy storage systems. Deviation from the ideal
operational temperaturee range (24–40 °C) can lead to a decrease in capacity, thermal efficiency, and increase the risk of thermal runaway. Therefore, an adaptive and efficient thermal management system is needed, especially for small-scale and off-grid applications. This research aims to design and implement a thermal monitoring system based on Peltier modules and fans, in real-time using a dual-core ESP32 microcontroller. The methodology used includes the design of hardware temperaturee sensors,current and voltage sensors, as well as thermal actuators (Peltier modules and fans). The system is controlled through ESP32 programming, which processes measurement data based on the actual temperaturee conditions. The monitoring display is conducted in real-time through the HMI. Testing is conducted during the and dis of the battery to evaluate the system's response to temperaturee changes. The experimental results demonstrate that the proposed system is capable of monitoring battery temperature in real time while maintaining a stable temperature distribution throughout the discharging process. The measured temperature difference (ΔT) ranged from 0.08 °C to 0.76 °C, indicating that the combination of a Peltier module and a cooling fan effectively minimized temperature differences among the measurement points, thereby maintaining the thermal stability of the battery pack during operation.
