Optimalisasi Charging Dan Discharging Pada Baterai Lithium Prototype Swab Engine Sepeda Motor Listrik WEN – KARLING 2R

Abstract

In this research an electric vehicle was designed, namely an electric motorcycle using fossil fuels compared to a 150 cc electric motorcycle system. The design of this electric motorbike vehicle is focused on knowing a comparative feasibility study between engine propulsion and electric propulsion. On this occasion we would like to develop research, especially on the lithium battery used so that its use/lifetime can last longer in the operation of the electric motorbike. The method used is quantitative where we will carry out direct measurements in the field and calculate the average daily use for several months and will calculate inventory and replenishment with simple statistical data. The expected results are that we can find out how much the ideal battery capacity needs and how long and when is the right time to charge the battery on the swab engine electric motorcycle. On a 4.8 Ah battery with a battery SOC of 80% it can last 310 minutes or 5 hours 10 minutes by traveling 34.9 km and the remaining average voltage is 54.86 V, with a capacity of 4.8 Ah so that the battery capacity decreased by around 18.3%. The greater the value of the discharge current used, the faster the battery capacity that can be used will decrease. In addition, the optimum value of charging and discharging occurs in the 120th minute with a voltage of 60 V.
