“…Switched capacitor cell balancing, also known as "Charge Shuttling" equalization, [10][11][12][13][14][15][16][17][18] utilize basically an external energy storage devices, capacitor(s) for shuttling the energy between the battery pack cells so as to the balancing. The capacitor shuttling can be categorized into four shuttling configuration; the basic switched capacitor, double-tiered switched capacitor, single switched capacitor and modularized switched capacitor topologies.…”

“…The capacity of the total battery pack will also decrease more quickly during operation then fail the battery system [1]. Quite a lot of cell balancing/equalization methods have been proposed in [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] and reviewed in [1][2][3][4][5][6][7]. The balancing topologies can categories as passive and active balancing; The passive balancing methods as proposed in [8][9] removing the excess energy from the fully charged cell(s) through passive, resistor, element until the charge matches those of the lower cells in the pack or a charge reference.…”

“…The active cell balancing methods remove the charges from higher energy cell(s) and deliver it to lower energy cell(s). It has different topologies according to the active element used for storing the energy such as capacitor and/or inductive component as well as the energy converters as [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Not a lot of cell balancing researches illustrate the switched capacitor cell balancing topologies such [10][11][12][13][14][15][16][17][18] that is may be due to the switched capacitor methods has a long equalization time, but on the contrary, they have a simple control strategy and high efficiency.…”

Battery systems as a vital part of the electrical vehicles are facing major difficulties, the most important matter is the cells unbalancing. The cells unbalancing leads to individual cell voltages differ over time, decreasing the battery pack capacity that consequently will fail of the total battery system in the long run.In addition, cell equalization acts an important role on the battery life preserving. Several cell balancing topologies have been proposed for battery pack equalization such as; switched shunt resistors, inductor/transformer base, shuttling capacitor and energy converters. Quite a few researches focused the capacitor base cell balancing. This paper is presents a review, comparisons and develop the capacitor based topologies for balancing battery string. With the aid of MATLAB/Simulink ® modeling, the switched capacitor topologies have been proposed including circuits, cells balancing simulation, implementations, balancing speed, complexity and system efficiency, as well as, propose a new control strategy for the single switched capacitor.

Battery management systems (BMS) are a key element in electric vehicle energy storage systems. The BMS performs several functions concerning to the battery system, its key task being balancing the battery cells. Battery cell unbalancing hampers electric vehicles' performance, with differing individual cell voltages decreasing the battery pack capacity and cell lifetime, leading to the eventual failure of the total battery system. Quite a lot of cell balancing topologies have been proposed, such as shunt resistor, shuttling capacitor, inductor/transformer based and DC energy converters. The shuttling capacitor balancing systems in particular have not been subject to much research efforts however, due to their perceived low balancing speed and high cost. This paper tries to fill this gap by briefly discussing the shuttling capacitor cell balancing topologies, focusing on the single switched capacitor (SSC) cell balancing and proposing a novel procedure to improve the SSC balancing system performance. This leads to a new control strategy for the SSC system that can decrease the balancing system size, cost, balancing time and that can improve the SSC balancing system efficiency.
