“…From the standpoint of electrical engineering, injecting current to and extracting current from a battery can result in charging and discharging, respectively (see Figure 10). According to the shape of this waveform, charging-discharging techniques fall into some of the following categories: constant current, constant voltage [59,60], sinusoidal-ripple current [3,[61][62][63][64], pulse voltage [2,[65][66][67][68][69], pulse current [1,6,10,19,[70][71][72][73], and reflex [20,45,[74][75][76][77][78][79]. Figure 10 summarizes the waveforms of these techniques.…”

There are many important trade-offs and constraints on cost, volume, weight, conduction losses, switching losses, microcontrollers, isolation, voltage and current levels, voltage and current ripples, battery specifications, charging–discharging algorithms, control system, switch gate drivers, and efficiency of battery chargers in electric vehicles. In this paper, a well-known power electronic topology commonly used in recent relevant studies is considered, and some important technical considerations with regard to the mentioned trade-offs and constraints are discussed in detail for the first time. The discussion concerns the practical and theoretical experiences in implementation of battery chargers and charging stations of electric vehicles exclusively, and it can be extended to various other power electronic topologies.

“…To enhance the charging performances and make a good balance between charging time and charging losses, many studies have been proposed. They can be categorized into three groups, which are (i) CC-CV-based methods [1]- [4] (ii) pulse chargingbased methods [5]- [11] and (iii) MSCC-based methods [12]- [19]. For category 1, ref.…”

“…Likely, authors in [3] implemented phase-locked loop control and adjust the charging current appropriately using the phase angle as a control variable. Furthermore, the current pumped charger developed in [4] utilized the pumped charging current as in the CC stage and then used pulse current as in the CV stage, which takes a similar time but reaches a higher efficiency compared with conventional CC-CV method. For category 2, different settings of current value, pulse width, and pause time enable plenty of combinations of charging configurations.…”

Lithium-ion (Li-ion) batteries play a substantial role in energy storage solutions for modernday technologies such as hand-held consumer electronics, aerospace, electric vehicles, and renewable energy systems. For Li-ion batteries, designing a high-quality battery charging algorithm is essential since it has significant influences on the performance and lifetime of Li-ion batteries. The objectives of a highperformance charger include high charging efficiency, short charging time, and long cycle life. In this paper, a model predictive control based charging algorithm is proposed, the presented technique aims to simultaneously reduce the charging time, and the temperature rise during charging. In this study, the coulomb counting method is utilized to calculate the future state-of-charge and an artificial neural network trained by experimental data is also applied to predict the future temperature rise. Comparing with the widely employed constant current-constant voltage charging method, the proposed charging technique can improve the charging time and the average temperature rise by 1.2 % and 4.13 %, respectively.

“…For example, the CC/CV method for Li-ion batteries seriously extends the charging time during the CV charging period and decreases the life of the battery at the same time [6]. Therefore many new battery charging methods have been researched in the literature [4][5][6][7][8][9][10][11][12][13][14][15][16]. Multistage charging [6][7][8] is proposed to apply different charging currents to optimize charge rates according to different states of charge (SOC).…”

This paper presents the analysis and design of a smart battery management system for Field Programmable Gate Array (FPGA) based portable electronic devices. It is a novel concept of incorporating the functionality of a smart battery management system into the FPGA used by portable electronic devices, which provides the following advantages. (1) It lowers cost since the conventional commercial independent battery management circuit can be eliminated; (2) It offers more flexibility because FPGA based battery management algorithms can be specifically designed for different battery chemistries of different devices and can provide the flexibility of algorithms and functionalities updating as well. Smart battery management system concepts include four aspects: (1) smart charging; (2) battery balancing; (3) smart discharging; and (4) safety operating. One novel charging algorithm, which combines the merits of multistage charging and pulse charging, is proposed to charge a Li-ion battery pack smartly. A Proportional Integral (PI) control method is introduced to achieve the current control of charging circuit with considerable close loop stability. Simulation results from the PSIM 9.0.4 software package and experimental results from the prototype built in the lab are demonstrated to verify the effectiveness of smart charging. The realizations of battery balancing, smart discharging, and safety operating are also briefly described by taking advantage of the proposed FPGA based smart battery management system topology, which verify the feasibility of the proposed FPGA based smart battery management system for portable electronic devices.
