This research focuses on developing a fast charging system to charge lithium-ion battery packs with a voltage rating of 48 volts. Standard battery charging uses a 0.25 C charging rate, which takes about 4 hours. The charging method in this study uses the constant current, constant voltage (CC-CV) method by adjusting the charging current at a charging rate of 1C, 2C, and 3C from the battery capacity. The buck converter determined the charging current value, setting it to produce a voltage of 53 V and a charging current of 10 A for a 1C charging rate, 20 A for a 2C charging rate, and 30 A for a 3C charging rate. Based on the testing, the battery charging time to reach 80% takes 57 minutes for charging rate 1C, 30 minutes for charging rate 2C, and 26 minutes for charging rate 3C.
