Analisis Pengaruh Pengaturan Arus dengan Kontroler Bldc Votol Em-150 pada Keseimbangan Performa terhadap Konsumsi Energi Baterai Lithium-Ion 72V 39Ah di Kendaraan Gokart Listrik

Abstract

Current setting is a factor that affects the performance of electric vehicle systems and their energy consumption. Without proper current setting or limitation, the BLDC motor will operate with uncontrolled current, which can lead to issues such as overheating, overcurrent, performance imbalance, and a decrease in energy efficiency, potentially damaging components of the electric go-kart in the long run. This study aims to analyze the effect of current setting using the Votol EM150 BLDC controller on performance balance and energy consumption in an electric Gokart with a 72V 39Ah lithium-ion battery, at various current limit settings of 50 A, 55 A, 60 A, 65 A, and 70 A. A data logger is used to record data during testing. The results show that the fastest acceleration time for the 70 A current limit is 6.89 seconds, with the lowest energy consumption of 9.043 Wh compared to other current limits. In the 1-lap test, with a distance of 1,100 meters, the maximum speed at the 70 A current limit is 70 km/h, with a travel time of 88.31 seconds and an energy consumption of 93.782 Wh. This study develops a prediction model specifically for the Mini Fishing Circuit to determine lap time and energy per lap for the electric go-kart. With this model, the optimal current setting can be identified to meet the target time of ≤ 90 seconds per lap, a target of 34 laps, a target distance of 35 km, and the ability to complete 30 laps with 5% energy remaining. The prediction model also successfully forecasts the energy used, remaining energy, and the time required for each current limit to complete the target of 7 to 15 laps, which can be used as a basis for planning and managing energy in various race applications as well as for recreational or entertainment use.
