A Ćuk Converter Cell Balancing Technique by Using Coupled Inductors for Lithium-Based Batteries

Abstract: In this paper, a c ´ uk converter balancing method by using a coupled inductor for lithium based batteries is investigated. The proposed circuit is an active balancing circuit that will equalize eight battery cells in a series. In electrical vehicles (EV), a battery management system (BMS) is a vital task to achieve the best performance of the batteries and longer lifetime. The problem of voltage difference in a battery pack is an important issue to be improved. To overcome the voltage differences in ba… Show more

“…Cuk converter [17][18][19] 2n − 2 MOSFETs, 2n-2 inductors, n-1 capacitors -Compares the voltages of two adjacent cells to control MOSFETs -Balancing time depends on the energy to be balanced, faster than inductor-based balance -DC voltage source with 2n − 1 differences is needed to control MOSFETs -Surge current may occur Buck-boost converter [20] n MOSFETs, n diodes, n inductors Most of the previous methods used the voltage of cells or reference current to control the balancing circuits. The voltage balancing control scheme is easy to implement and low cost.…”

“…They do not cause electrical energy wastage, although the structure of the balancing circuit and control strategies are complex, especially for a large electrical storage system with many series-connected cells. There are several different circuit topologies and control methods, such as capacitor-based [12][13][14], inductor-based [15,16], and converter-based methods [17][18][19][20]. The circuit components and main characteristics of various active balancing methods are summarized in Table 1.…”

“…Thus, battery equalizers are needed to ensure that all cells in a series-connected battery string are fully charged or discharged. Many battery equalizers have been proposed in the last few years [13][14][15][16][17][18][19][20][21][22]. These applications are divided into a passive balancing technique and an active balancing technique.…”
