Manufacturing of 18650 lithium batteries for electric bamboo scooters

Abstract

Abstract The use of batteries as an energy source that can convert chemical energy into electrical energy is used to drive a dynamo (BLDC) through the controller. Electric scooter batteries are made using 18650 batteries arranged in series. The series circuit of the 18650 battery that is arranged can be known by the number of series circuits based on the BMS used. The Battery Management System (BMS) acts as a system that can manage the use of battery power and an auxiliary system for charging from a series of batteries. This research aims to develop efficient and reliable batteries for use in electric scooters. The research method used is qualitative by analyzing the manufacture of batteries starting from assembling a series of batteries to the stage of testing the battery on an electric scooter. Battery arrangement is done by using holders in each row and connected using a nickel plate on the positive and negative poles in one row, then connecting the battery to BMS is done by soldering the positive and negative pole wires from BMS to the battery circuit with 20 series circuits and connecting the BMS cables. with a circuit as a battery charging system. Test results show that the 18650 series and BMS 72V 20 series are able to provide good performance. The 18650 and BMS 72V 20 series battery range can be a promising solution to increase the performance and battery life in electric scooter.
