This paper introduces a charging strategy for maximizing the instantaneous efficiency ( ) of the lithium-ion (Li-ion) battery and the interfacing power converter. A theory based on the trade-off between several designed Li-ion battery packs and dual-active-bridge (DAB) converter efficiencies is established to find the best compromise. The proposed framework enables Vehicle-to-Everything (V2X) functionality for an electric vehicle providing energy services. Typically, power converters, in particular DAB converters, present low efficiency at light loads and higher values at high power levels. On the other hand, the battery efficiency decreases linearly as the current increases. Therefore, an optimum C-rate could be selected to operate the converter and the battery to minimize the overall losses. Both simulations and experimental results are presented to validate the correctness of the theoretical analyses. The …

Silicon (Si) has a high theoretical gravimetric capacity and can replace the graphite in the negative electrode of lithium-ion batteries. Among numerous Si electrode geometries, the Si microwire (SiMW) geometry shows a promising performance compared to Si wafers and particles and alleviates the mechanical instability during lithiation/delithiation process due to high volume expansion/contraction. In this paper, a single-wire model (SWM) is proposed for lithium-ion battery half-cell composed of SiMWs as the positive electrode and lithium metal as the negative/reference electrode. In the proposed SWM, an array of SiMWs is modeled by only one equivalent micro-scale wire. The SWM is the simplest model that incorporates the electrochemical behavior with a minimal computational effort suitable for real-time applications. Despite its simplicity, it is equivalent to a one-dimensional (1D) model of conventional graphite …

During fast charging of Lithium-Ion batteries (LIB), cell overheating and overvoltage increase safety risks and lead to faster battery deterioration. Moreover, in conventional Battery Management Systems (BMS), the cell balancing, charging strategy and thermal regulation are treated separately at the expense of faster cell deterioration. Hence, this paper proposes an optimized fast charging and balancing strategy with electrothermal regulation of LIB packs. Thereby, the power dissipation constraints of the passive balancing are introduced in the proposed integrated optimal framework and cell balancing is achieved by bypassing the extra charging current. The electrothermal model of the cells, along with a battery pack formed by a string of cells, is implemented. Extensive experiments are carried out to identify the coefficients for the Lithium-Ion cell model, i.e. Samsung-INR18650-20R, and the charging current trajectory …

The need to increase the charging speed of lithium-ion (Li-ion) battery energy storage systems (BESS) has led to the usage of high-voltage (HV) battery packs in e-mobility applications. External short-circuits (ESCs) might lead to high current rates far beyond the nominal current of a battery pack and hence impose severe impacts on Li-ion batteries by raising the temperature. Moreover, the solid-electrolyte interface (SEI) layer thickness growth rate quickens the capacity fade mechanism due to the increased side reaction current density. To minimize these effects, high-speed and robust protection schemes are required to eliminate ESCs from Li-ion battery pack terminals. In this context, the paper proposes an advanced high-speed protection scheme based on a wide-bandgap (WBG) semiconductor. It is a promising solution to replace the conventional method based on magnetic circuit breakers. Finally, experimental …

This paper presents an optimum potential theorem to model the large volume expansion and deformation of Silicon-Mircrowire (Si-MW) anode. Among different silicon anodes, Si-MW is a promising replacement for graphite in lithium-ion batteries (LIBs) leading to high energy density required for electric vehicles (EVs). Nonetheless, charging and discharging of Si-MW result in severe volume expansion and deformation which eventually leads to battery accelerated degradation and capacity fade. A theory is developed to model the phenomenon considering the total free energy and dissipative components. The conservation laws and constitutive relations for Si-MW are connected to the free energy by defining suitable functions. The model equations are discretized and solved using finite-element method (FEM) employing FEAP solver engine. Qualitative sensitivity analysis is conducted on model parameters. The …

The increasing demand for high efficiency and high power density is impelling converters and devices to a limit. Wide-band gap devices, such as GaN HEMTs, have the ability to increase power density without affecting power losses. In this context, multiport isolated converters based on multiwinding transformers (MWT) are able to increase the efficiency and power density of the converter, in particular for low-power applications. For this reason, this paper proposes a topology, which is particularly useful for high-current applications, such as those required by onboard systems in electric vehicle (EV) applications. Moreover, this paper evaluates the different multiport resonant converters taking into account their efficiencies, operation under distinct voltage levels, and parameter mismatches. Finally, the effectiveness of the converter is validated by using analytical simulations and experimental results. For this purpose, a …

Silicon-based Lithium-ion batteries are emerging in industry. Their high energy density promises an optimum solution for e-mobility applications. This paper investigates open-circuit voltage (OCV) characterization methods for microporous silicon (MP-Si) anodes. Two MP-Si samples of the capacity of 2.5 mAh are built in the laboratory. Pulse tests are applied to the two different samples. The OCV of MP-Si measured during charging and discharging are different leading to a hysteresis behavior. MP-Si OCV is approximated by different functions for charging and discharging. Considering the RMS error, polynomial approximation is the best option. A fictitious equilibrium potential is derived based on the difference in energy losses during the charging and discharging and characterized for MP-Si based on the experimental results.

We present a chemo‐mechanical finite element method model for the breathing effect of the silicon anode during lithiation and delithiation. The model is based on the framework for gradient extended standard dissipative solids. It couples diffusion of lithium ions, phase transformation with a moving phase boundary, and the related volume changes, which lead to mechanical stresses in the material. The driving force for diffusion is given by the gradient of the electrochemical potential. Phase transformation and phase boundary movement are described by the Allen–Cahn equation in combination with a constrained double obstacle potential. To shift the constraint from the nodes to the Gauss points, the model makes use of the micromorphic approach.

The dual-side control (DSC) of inductive power transfer (IPT) generally requires communication between the system sides to coordinate the local controllers. For the reduction of component count and operation in challenging environments, such as underwater, communicationless DSC is beneficial. This article investigates if and how asymmetric modulations, known for their improved performance in IPT, can be applied to phase cooperative communicationless DSC. A per side separate steady-state model is derived, and the selection criteria for modulation schemes to be suitable for phase cooperative control are determined. The crucial importance of bijective or unique phase behavior in modulations for this control scheme is identified and demonstrated. In comparison with phase modulation, it is shown that the asymmetric voltage cancelation of full-bridges is not reliably applicable to phase cooperative DSC, but …

As an indispensable interface, a battery management system (BMS) is used to ensure the reliability of Lithium-Ion battery cells by monitoring and balancing the states of the battery cells, such as the state of charge (SOC). Since many battery cells are used in the form of packs, cell temperature imbalance may occur. Current approaches do not solve the multi-objective active balancing problem satisfyingly considering SOC and temperature. This paper presents an optimal control method using reinforcement learning (RL). The effectiveness of BMS based on Proximal Policy Optimization (PPO) agents obtained from hyperparameter optimization is validated in simulation narrowing the values to be balanced at least 28%, in some cases up to 72%. The RL agents let the active BMS select the optimal cell and regulates current for the balance of SOC and temperature between battery cells.

Medium voltage (MV) to low voltage (LV) isolated DC/DC converters can be realized with the MMC on the MV-side due to its unique features such as modularity and scalability. In this application, quasi two-level (Q2L) waveform in the AC side of MMC guarantees controllable dv/dt and small capacitor size for MMC submodules (SMs). There are different techniques including nearest level modulation (NLM), phase shift modulation (PSM), and single carrier modulation (SCM), which can be used to generate a Q2L waveform. In this paper, the total MMC losses, capacitor voltage ripple, and implementation complexities are used to compare these modulation techniques. Simulation and experimental results indicate that the SCM outperforms NLM and PSM in terms of lower losses and implementation complexity.

Power Line Communication (PLC) and Simultaneous Wireless Information and Power Transfer (SWIPT) are popular examples of applications, where power and information are transmitted simultaneously. In most cases, different devices have been used to generate the power and communication signals independently. Usually, the information is superimposed onto the power signal using an external modulator. Recently, power converters have been used to generate pulses not just for power conversion but also for information transfer simultaneously. This approach represents a fundamental difference because it exploits the signal processing potential of Pulse Width Modulation (PWM), where for power conversion only the average pulse width is used, while the information is represented by the harmonics instead of being filtered out, as typically done in power electronics. The concept of embedding information into …

The modular multilevel converter (MMC) is a promising topology for enabling hybrid grids, which includes different medium- and low-voltage (MV and LV) ac and dc grids. Owing to its capability to break dc current and work in buck mode, especially, MMCs have been widely studied for MVdc applications in ac-dc hybrid grids. It has been adopted as a frontend bidirectional ac-dc converter or a dc-dc converter employing medium frequency transformers to enable ultra-fast charging stations. Furthermore, MMC can provide different levels of LVdc by expanding the topology with an additional converter, which can help to realize a multibus dc distribution grid. Finally, this property can be used to realize a solid-state transformer (SST) for hybrid grids. However, it is required to identify and characterize the merits and demerits of various MMC structures available to form multibus dc distribution systems. Therefore, in this paper …

Talkative power conversion (TPC), which embeds information into the switching ripple to achieve the simultaneous transmission of power and data without installation of additional hardware, can reduce the additional communication infrastructure in cyber-physical systems of smart grid and renewable power plants. The TPC in DC/DC converters has been the subject of numerous investigations, but comparatively few studies have focused on the DC/AC converters. In this paper, the space-vector pulse width modulation (SVPWM)-based TPC techniques including both variable zero vector width modulation (VZVWM) and variable zero vector position modulation (VZVPM) for three-phase DC/AC converters are proposed. The DC/AC converters can transmit information to the receiver, crossing the LCL filter and power cable, with a good power quality. The sliding FFT method is employed for demodulation, and the bit rate …

A modular multilevel converter (MMC) based isolated DC-DC converter is an interesting topology enabling medium-voltage DC (MVDC) grid-connected EV charging stations, an efficient solution for reducing power conversion stages. In modulations applied to MMC based DC-DC converters, a quasi-two-level (Q2L) modulation is suitable for medium-frequency (MF) DC-DC conversion and can reduce stresses on a transformer due to a low dv/dt characteristic. However, attention must be paid to balancing DC capacitor voltages between the submodules (SMs), and it is hard to apply the existing methods in practice because of the complex balancing algorithm. Therefore, this paper proposes a new modulation with inherent SM DC capacitor voltage balancing for the MMC, which is used as a primary converter of MVDC isolated DC-DC converters. The proposed modulation can achieve the natural balancing of the DC …

Medium voltage (MV) modular multilevel converter (MMC) is an attractive candidate for multi MW fast charging station (FCS) to transfer high power with high efficiency, and a medium-frequency (MF) isolated dual active-bridge (DAB) DC/DC converter is needed to step down the voltage in this application. In this regard, MMC-based isolated DAB DC/DC converter is a good candidate to be used in FCS. In MMC-based isolated DAB DC/DC converter, Quasi-two-level (Q2L) waveform is the preferred waveform for the AC side voltage of MMC due to low dv/dt and small capacitor of submodules. The analysis on power losses of MMC in this application and with this specific AC voltage waveform is an important issue for a cellular high-efficiency design that requires more investigation. This paper provides an analysis to estimate switching and conduction losses of MMC used to produce a quasi-two-level waveform which can …

Talkative power converter (TPC), which embeds signals into switching ripple, achieving the power line communication (PLC) and consequently enabling the power to communicate, has been proposed recently to significantly enhance the coordination control capability of power converter-interfaced resources. Since the talkative power (TP) is an emerging technique and a special PLC, a comprehensive overview of the advanced PLC techniques and the application scenarios of talkative-power-based PLC (TP-PLC) is missing in current literature. Hence, in this paper, a review of switching-ripple-based PLC (SR-PLC) techniques is detailed, to summarize their advances and performances in terms of the SR-PLC principles, SR-PLC in non-isolated converter and isolated converter, as well as the applications in visible light communication, battery management system, switching reluctance generator/motor and wireless …

The design of charging strategies for lithium-ion (Li-ion) batteries depends on the application. In electric vehicle applications, high charging speed and long battery life are essential requirements. However, with the advent of vehicle-to-grid (V2G) and potential remuneration for electric grid support, maximum user profit could gain increasing interest through efficient operation that also optimizes battery health. Conventional constant-current constant voltage (CCCV) and constant-power constant-voltage (CPCV) charging strategies do not include the optimum efficiency of the battery and charging stations. In this paper, a charging strategy is introduced aiming at maximizing the instantaneous efficiency of the Li-ion battery and the charging station which minimizes the energy waste. For this purpose, 18650 Li-ion cells and a dual-active-bridge (DAB) converter are considered in the simulations and experimental …

Frequency domain impedance of Li-ion batteries contains valuable information about the state of charge (SOC) and state of health (SOH). Normally, electrochemical impedance spectroscopy (EIS) is performed during the relaxation of battery cells. However, performing EIS during the batteries operation has been achieved through switching power converters. This paper reviews the power converter topologies for both online and offline Electrochemical Impedance Spectroscopy (EIS) characterization of batteries. The information that can be extracted from EIS Nyquist plots are discussed. Comparative analysis between converter topologies is presented. Finally, challenges are identified and new converter topologies are proposed for further consideration in online/offline EIS characterization.

Kalman filtering is commonly used for state-of-charge (SOC) estimation for lithium-ion (Li-ion) batteries owing to its simplicity, computational efficiency, and relatively precise results. However, kalman filters depend on the Li-ion battery model. Several laboratory tests such as incremental current and dynamic stress tests are required to determine battery model parameters in model-based SOC estimation. These tests such as incremental current test and dynamic stress test are time-consuming and can take multiple days. A mathematical optimization along with a battery test method, which does not need rest time for battery, are adopted to reduce the battery parameter identification time, drastically. A mathematical optimization stage is embedded prior to Kalman Filter based SOC estimation computing the battery open circuit voltage (OCV) and as well as an initial guess of the RC parameters of the battery equivalent …
