“…However, an advanced and universal battery testing system should be developed to avoid different equipment errors; Very less work has been done for the SOC estimation of battery packs. Further work is required in this area; others existing issues such as cell balancing, self-discharge, and estimation of maximum capacity, hysterics issues, and rate of charge/discharge issue must be taken care with advanced technologies/models [9,24,41,49].

Energy shortage and environmental pollution issues can be reduced considerably with the development and usage of electric vehicles (EVs). However, electric vehicle performance and battery lifespan depend on a suitable battery arrangement to meet the various battery performance demands. The safety, reliability, and efficiency of EVs largely depends on the constant monitoring of the batteries and management of battery packs. This work comprehensively reviews different aspects of battery management systems (BMS), i.e., architecture, functions, requirements, topologies, fundamentals of battery modeling, different battery models, issues/challenges, recommendations, and active and passive cell balancing approaches, etc., as compared to the existing works which normally discuss one or two aspects only. The work describes BMS functions, battery models and their comparisons in detail for an efficient operation of the battery pack. Similarly, the work presents a comprehensive overview of issues and challenges faced by BMS and also provides recommendations to address these challenges. Cell balancing is very important for the battery performance and in this work various cell balancing methodologies and their comparisons are also presented in detail. Modeling of a cell balancer is presented and a comparative study is also carried out for active and passive cell balance technique in MATLAB/Simulink with an eight cell battery packcell balancing approach. The result shows that the active cell balancing technique is more advantageous than passive balancing for electrical vehicles using lithium-ion batteries.

Among various energy sources for an electric vehicle, battery occupies its prominent place for its high energy density and high power density. Among various battery chemistries, a Li-ion battery has become the strong contender in electric vehicle industry. The battery cells are either connected in series or parallel for a battery pack to achieve higher voltage and current for electric vehicle application.The battery management system act as a brain of the battery operated electric vehicle. The modeling of the battery pack system is the necessary phenomena for any proposed battery management system. The series connected cells in the battery pack should maintain the same potential of individual cell at ideal, charging and discharging conditions. If the potential of the series connected cells are mismatched then the charging and discharging of the battery pack is affected. This invokes the problem of cell unbalancing due to both extrinsic and intrinsic parameters. The problem could be overcome by using cell to cell balancing, cell -module balancing with the board classification of active and passive balancing. By implementing the proper cell balancing methodology the equalization time of the battery pack is lowered and the aging of the battery pack is improved. The survey explains the battery parameters, role of battery management system and various methods of cell balancing for an electric vehicle application.

“…The safety and proper operation of lithium-ion (Li-ion) battery packs, composed of series-connected cells, require an advanced battery management system (BMS) [1]. This system controls every aspect of the battery pack, including temperature [2,3], safety [4,5], charging and discharging, cell voltage and current monitoring [6], fault diagnosis, data acquisition [4], battery state of charge (SOC) and state of health (SOH) [4,7], and cell balancing [8][9][10][11][12][13][14]. The latter ensures that all cell voltages are within the desired range, thus optimising usage and lifetime.…”

The battery pack is at the heart of electric vehicles, and lithium-ion cells are preferred because of their high power density, long life, high energy density, and viability for usage in relatively high and low temperatures. Lithium-ion batteries are negatively affected by overvoltage, undervoltage, thermal runaway, and cell voltage imbalance. The minimisation of cell imbalance is particularly important because it causes uneven power dissipation by each cell and, hence, temperature distribution that adversely impacts the battery lifetime. Several papers in the literature proposed advanced cell-balancing techniques to increase the effectiveness of basic cell-balancing approaches, reduce power losses, and reduce the number of components in balancing circuits. The new developments and optimisations over the last few years have been particularly intense due to the increased interest in battery technologies for several end-use applications. This paper reviews and discusses recent cell-balancing techniques or methods, covering their operating principles and the optimised utilisation of electrical components.
