The increasing popularity of the electric vehicles (EVs) is due to various environmental impacts of the gasoline‐/diesel‐based vehicles over the past few decades. EVs are commercialized in various parts of world but their full‐scale commercialization has not yet attained. Despite of many advantages, challenges associated with the use of EVs are their range anxiety, slow charging, and the performance/cost of battery. A thorough review from the year 2006 to 2020 is conducted in the field of battery management system (BMS). Herein, various functions, advantages, and disadvantages of methods used in BMS for cell balancing, thermal management, and protection of battery against over‐voltage and over current, estimation of state of health, and estimation of state of charge of battery are discussed. Additionally, critical gaps are identified and a framework for design of an efficient BMS is proposed. The deployment of advanced intelligent and smart technologies such as digital‐twin of battery pack, cyber‐physical systems, battery swapping technology, nondestructive testing, self‐reconfigurable batteries, and prudent recycling/reusability using automation are also discussed. In‐brief, critical gaps; advanced technologies and framework that researchers can use to develop comprehensive systems comprising advanced BMS; real‐time battery monitoring, and battery reusability and recycling; as a whole complete unit are provided.

Renewable energy systems and electric vehicles (EVs) are receiving much attention in industrial and scholarly communities owing to their roles in reducing pollutant emissions. Integrated energy systems (IES), which connect different types of renewable energies and storages, have become common in many applications, such as the grid-connected photovoltaic (PV) and battery systems, fuel cells and battery/supercapacitor in EVs. The advantages of all energy sources are maximized by utilizing connection and control strategies. Because many storage systems and household loads are mainly direct current (DC) types, the DC grid has considerable potential for increasing the efficiency of distribution grids in the future. In IES and future DC grid systems, the triple active bridge (TAB) converter is an isolated bidirectional DC-DC converter that has many advantages as a core circuit. Therefore, this paper reviews the characteristics of the TAB converter in current applications and suggests next-generation applications. First, the characteristics and operation modes of the TAB converter are introduced. An overview of all current applications of the TAB converter is then presented. The advantages and challenges of the TAB converter in each application are discussed. Thereafter, the potential future applications of the TAB converter with an adaptable power transmission design are presented.

Li‐ion batteries are influenced by numerous features such as over‐voltage, undervoltage, overcharge and discharge current, thermal runaway, and cell voltage imbalance. One of the most significant factors is cell imbalance which varies each cell voltage in the battery pack overtime and hence decreases battery capacity rapidly. To increase the lifetime of the battery pack, the battery cells should be frequently equalized to keeps up the difference between the cells as small as possible. There are different techniques of cell balancing have been presented for the battery pack. It is classified as passive and active cell balancing methods based on cell voltage and state of charge (SOC). The passive cell balancing technique equalizing the SOC of the cells by the dissipation of energy from higher SOC cells and formulates all the cells with similar SOC equivalent to the lowest level cell SOC. The active cell balancing transferring the energy from higher SOC cell to lower SOC cell, hence the SOC of the cells will be equal. This review article introduces an overview of different proposed cell balancing methods for Li‐ion battery can be used in energy storage and automobile applications.
