Abstract

Konversi sepeda motor BBM ke listrik merupakan bentuk perubahan sepeda motor dengan mesin ICE (Internal Combustion Engine) menjadi mesin motor listrik bertenaga baterai. Sepeda motor konversi ini memiliki permasalahan controller yang sering mengalami kerusakan akibat overheat ketika digunakan lebih dari 70°C pada suhu komponen MOSFET, serta memberikan pengaman tambahan untuk mencegah panas berlebih pada motor BLDC agar tidak bekerja terlalu lama di atas 80°C. Dengan demikian, diperlukan sistem yang dapat melakukan engine cut off pada sepeda motor konversi untuk mencegah terjadinya panas berlebih yang menyebabkan kerusakan komponen dan pengurangan masa pemakaian. Pembuatan sistem ini berupa klasifikasi tingkat suhu controller dan suhu penggerak berupa motor BLDC dengan memanfaatkan pembacaan data HEX 24 byte dari controller. Dalam proses klasifikasi ini digunakan metode fuzzy logic untuk membantu menentukan ouput nilai persentase engine cut off risk. Engine cut off akan aktif ketika nilai persentase lebih dar 98%. Engine cut off ini bekerja dengan cara relay memutuskan jalur sinyal throttle sehingga membuat sepeda motor tidak bisa digas dan berhenti perlahan. Dari hasil implementasi alat pada saat engine cut off aktif terjadi penurunan kecepatan motor dari 1046 RPM ke 0 RPM yang membuat suhu controller mengalami penurunan sebesar 12,67% dari 71°C menjadi 62°C. Namun, penurunan kecepatan motor tidak berpengaruh terhadap suhu motor yaitu tetap di 77°C. Pada hasil perhitungan fuzzy di alat dengan hasil simulasi MATLAB memiliki rata-rata eror sebesar 1,956%.

Conversion of BBM motorcycles to electric is a form of changing a motorcycle with an ICE (Internal Combustion Engine) engine into a battery-powered electric motor engine. This conversion motorcycle has a controller problem that often experiences damage due to overheating when used more than 70° C in MOSFET component temp, and provides additional safety to prevent overheating of the BLDC motor so that it does not work too long above 80° C. Thus, a system is needed that can perform engine cut off on conversion motorcycles to prevent overheating which causes component damage and reduced service life. The creation of this system is in the form of a classification of the controller temperature level and the BLDC motor drive temperature by utilizing the reading of 24 byte HEX data from the controller. In this classification process, the fuzzy logic method is used to help determine the output of the engine cut off risk percentage value. The engine cut off will be active when the percentage value is more than 98%. This engine cut off works by the relay disconnecting the throttle signal path so that the motorcycle cannot be accelerated and stops slowly. From the results of the implementation of the tool when the engine cut off is active, there is a decrease in motor speed from 1046 RPM to 0 RPM which causes the controller temperature to decrease by 12.67% from 71° C to 6 ° C. However, the decrease in motor speed does not affect the motor temperature which remains at 77° C. The results of the fuzzy calculation on the tool with the MATLAB simulation results have an average error of 1.956%.
