Baterai memainkan peran penting dalam mendukung perkembangan teknologi dengan menyediakan energi untuk perangkat portabel. Penting untuk menjaga baterai dalam kondisi baik agar dapat menghindari risiko seperti short circuit, overheat, atau ledakan. Pendeteksian suhu baterai melalui sensor suhu terintegrasi membantu memonitor kondisi baterai secara real-time. Sistem peringatan dini dapat memberitahu pengguna atau mengambil tindakan jika suhu baterai melebihi batas aman. Penting untuk mengikuti pedoman produsen dan menghindari penggunaan jenis baterai yang kurang berkualitas untuk menjaga keamanan dan kinerja baterai. Penelitian ini menggunakan metode desain eksperimental. Perancangan prototipe detektor suhu menggunakan sensor Thermocouple type-k dengan modul MAX6675. Prototipe ini memiliki output berupa alarm dari Buzzer, tampilan layar dari LCD, dan notifikasi Aplikasi Blynk pada smartphone. Prototipe detektor suhu diuji pada sel baterai Lithium-ion 18650 yang mengalami overcharge dengan memberikan arus konstan 3 ampere. Empat sampel baterai disiapkan dengan tingkat State of Charge (SOC) 0% dan 50%. Selama pengujian, suhu permukaan sel baterai terus diukur oleh detektor suhu, dan data tersebut dianalisis untuk mengidentifikasi pola perubahan suhu. Detektor suhu diprogram untuk menentukan batas suhu aman, dan evaluasi dilakukan untuk mengukur efektivitas kinerja detektor dalam mendeteksi kondisi overcharge pada baterai Lithium-ion. Tujuan utama pengujian adalah memastikan keselamatan dan kinerja optimal detektor suhu. Hasil penelitian ini menunjukkan bahwa pengujian overcharging dengan menggunakan sensor Thermocouple type-k mampu mengukur kenaikan suhu permukaan baterai. Kenaikan suhu rata-rata baterai dimulai dari 70℃. Hasil pengujian kalibrasi Thermocouple type-k dengan termometer air raksa menunjukkan adanya error sebesar 2,04%. Kata kunci: Baterai lithium, overcharging, deteksi suhu. ***** Batteries are objects that have a very important function in technological development because energy needs are increasing. The battery is expected to be in good condition which can support devices that use batteries as their energy supply, errors or damage to the battery such as short circuits, overheating or explosions. One of the important things in using batteries is an early warning system if the battery experiences an undesirable condition. with a temperature detection system you can find out the battery temperature condition directly. This research uses an experimental design method. Design of a temperature detector prototype using a K-type thermocouple sensor with the MAX6675 module. This prototype has output in the form of an alarm from a buzzer, a screen display from an LCD, and notifications from the Blynk application on a smartphone. The temperature detector prototype was tested on an overcharged 18650 Lithium-ion battery cell by providing a constant current of 3 amperes. Four battery samples were prepared with State of Charge (SOC) levels of 0% and 50%. During testing, the surface temperature of the battery cells is continuously measured by a temperature detector, and the data is analyzed to identify temperature change patterns. The temperature detector is programmed to determine safe temperature limits, and evaluations are carried out to measure the effectiveness of the detector's performance in detecting overcharge conditions in Lithium-ion batteries. The main goal of testing is to ensure safety and optimal temperature detector performance. The results of this research show that overcharging testing of the type-k Thermocouple sensor can measure the increase in battery temperature. The significant increase in the average temperature read by the sensor starts from 70°C, and the prototype calibration results have an error of 2.04% errors Keywords: Lithium battery, overcharging, temperature detection,
