Design and Simulation of The Multistage Constant-Current Charging System with Passive Balancing BMS for Lithium-Ion Batteries

Abstract

Energy storage systems have been widely used in the electric vehicle and renewable energy systems. Lithium-Ion batteries are one type of widely used energy storage system. Lithium-Ion batteries are sensitive to over current, temperature, and voltage. An appropriate method in charging Lithium-Ion batteries is needed to ensure optimal battery performance and long battery life. The Multistage Constant-Current Charging System with Passive Balance BMS for Lithium-Ion batteries is expected to be a solution for charging Lithium-Ion batteries fast but still under the characteristics of Lithium-Ion batteries. Multi Stage Constant Current Charging with Passive Balance BMS for Lithium-Ion batteries utilizes a boost converter circuit in the charging process and maintains current values as needed. Besides, it also uses the Switching Shunt Resistor method in the BMS passive balance process.
