Abstract
Electric vehicles generally use batteries for energy storage, but currently there are designs for electric vehicle energy storage using supercapacitors (SC) or a combination of batteries and SC. In previous research, an electric motorcycle was made using a Suzuki Shogun SP125 chassis and cover, 800-1000 BLDC motor and controller. This research is to get a comparison between the use of Lithium Iron Phosphate (LFP) and SC batteries that installed on electric motorbikes using 2 passenger weight variables. The data taken are mileage, speed, acceleration, and battery charging time. The LFP battery pack used consists of a 51.2Volt 18Ah LFP HX32700 battery. The capacitor used consists of 18 pieces of 2.7v 500F Capacitors arranged in series, resulting in a 48.6volt 27.78Farad supercapacitor. Tests were carried out by installing LFP and SC alternately on electric motorbikes with variable passenger weights of 67 kg and 118 kg. The results are obtained that the acceleration data with SC is higher than that with LFP, this is because the power output issued by SC is greater and faster than LFP. The disadvantage of SC in this research is that the power capacity is lower than that of LFP, resulting in a shorter electric motorcycle range.
