Abstract
Dependence on fossil energy in the transportation sector poses a major challenge in efforts to reduce carbon emissions and enhance energy sustainability. Electric bicycles utilizing a solar photovoltaic (PV) charging system offer an environmentally friendly solution by harnessing solar energy as the primary power source. However, charging efficiency remains a crucial factor influenced by various variables, such as solar intensity, battery conditions, and system design and control. This study aims to analyze the charging efficiency of electric bicycle batteries using a solar PV system through a three-day test conducted in two time segments: morning-midday (08:00–12:00) and midday-afternoon (13:00–17:00). The analyzed parameters include voltage, current, input and output power, and charging efficiency. The results indicate that charging efficiency is higher in the morning-midday segment compared to the midday-afternoon segment. On Day 1, the morning-midday segment recorded an efficiency of 74.5%, whereas the midday-afternoon segment only reached 28.7%. On Day 3, a significant efficiency improvement was observed, with values reaching 82.7% in the morningmidday segment and 93.5% in the midday-afternoon segment, highlighting the positive influence of system design and environmental conditions. The key factors affecting charging efficiency include solar intensity, solar panel orientation, battery conditions, and the charging control system. To enhance system performance, this study recommends using high-efficiency solar panels and advanced control systems such as Maximum Power Point Tracking (MPPT). These findings are expected to serve as a reference for the development of renewable energy technology, particularly in optimizing solar-powered electric vehicle charging.

Ketergantungan pada energi fosil dalam sektor transportasi menjadi tantangan utama dalam upaya mengurangi emisi karbon dan meningkatkan keberlanjutan energi. Sepeda listrik yang menggunakan sistem pengisian daya berbasis solar photovoltaic (PV) menawarkan solusi ramah lingkungan dengan memanfaatkan energi matahari sebagai sumber utama. Namun, efisiensi pengisian daya masih menjadi faktor krusial yang dipengaruhi oleh berbagai variabel, seperti intensitas cahaya matahari, kondisi baterai, serta desain dan kontrol sistem. Penelitian ini bertujuan untuk menganalisis efisiensi pengisian daya baterai sepeda listrik menggunakan sistem solar PV dengan pengujian selama tiga hari dalam dua segmen waktu, yaitu pagi-siang (08.00–12.00) dan siang-sore (13.00–17.00). Parameter yang dianalisis meliputi tegangan, arus, daya input dan output, serta efisiensi pengisian daya. Hasil penelitian menunjukkan bahwa efisiensi pengisian daya lebih tinggi pada segmen pagi-siang dibandingkan dengan segmen siang-sore. Pada Hari ke 1, efisiensi segmen pagi-siang tercatat sebesar 74.5%, sedangkan siang-sore hanya mencapai 28.7%. Hari ke 3 menunjukkan peningkatan efisiensi signifikan, dengan nilai 82.7% pada pagi-siang dan 93.5% pada siang-sore, menunjukkan pengaruh positif dari desain sistem dan kondisi lingkungan. Faktorfaktor utama yang memengaruhi efisiensi pengisian meliputi intensitas cahaya matahari, orientasi panel surya, kondisi baterai, serta sistem kontrol pengisian. Untuk meningkatkan kinerja sistem, penelitian ini merekomendasikan penggunaan panel surya dengan efisiensi konversi tinggi dan sistem kontrol canggih seperti Maximum Power Point Tracking (MPPT). Temuan ini menjadi referensi dalam pengembangan teknologi energi terbarukan, khususnya dalam optimalisasi pengisian daya kendaraan listrik berbasis tenaga surya.
