Available in PDF, EPUB and Kindle. Book excerpt: Life Prediction Model for Grid-Connected Li-ion Battery Energy Storage System: Preprint Lithium-ion (Li-ion) batteries are being deployed on the electrical grid for a variety of purposes, such as to smooth fluctuations in solar renewable power generation. The lifetime of these batteries will vary depending on their thermal environment and how they are charged and discharged. To optimal utilization of a battery over its lifetime requires characterization of its performance degradation under different storage and cycling conditions. Aging tests were conducted on commercial graphite/nickel-manganese-cobalt (NMC) Li-ion cells. A general lifetime prognostic model framework is applied to model changes in capacity and resistance as the battery degrades. Across 9 aging test conditions from 0oC to 55oC, the model predicts capacity fade with 1.4 percent RMS error and resistance growth with 15 percent RMS error. The model, recast in state variable form with 8 states representing separate fade mechanisms, is used to extrapolate lifetime for example applications of the energy storage system integrated with renewable photovoltaic (PV) power generation.

Book Synopsis Degradation Mechanisms and Lifetime Prediction for Lithium-Ion Batteries -- A Control Perspective: Preprint by :
Download or read book Degradation Mechanisms and Lifetime Prediction for Lithium-Ion Batteries -- A Control Perspective: Preprint written by and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predictive models of Li-ion battery lifetime must consider a multiplicity of electrochemical, thermal, and mechanical degradation modes experienced by batteries in application environments. To complicate matters, Li-ion batteries can experience different degradation trajectories that depend on storage and cycling history of the application environment. Rates of degradation are controlled by factors such as temperature history, electrochemical operating window, and charge/discharge rate. We present a generalized battery life prognostic model framework for battery systems design and control. The model framework consists of trial functions that are statistically regressed to Li-ion cell life datasets wherein the cells have been aged under different levels of stress. Degradation mechanisms and rate laws dependent on temperature, storage, and cycling condition are regressed to the data, with multiple model hypotheses evaluated and the best model down-selected based on statistics. The resulting life prognostic model, implemented in state variable form, is extensible to arbitrary real-world scenarios. The model is applicable in real-time control algorithms to maximize battery life and performance. We discuss efforts to reduce lifetime prediction error and accommodate its inevitable impact in controller design.
Book Synopsis Experimental Aging and Lifetime Prediction in Grid Applications for Large-Format Commercial Li-Ion Batteries by :
Download or read book Experimental Aging and Lifetime Prediction in Grid Applications for Large-Format Commercial Li-Ion Batteries written by and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the growth of electric vehicle and stationary energy storage markets, the production and use of lithium-ion batteries has grown exponentially in recent years. For many of these applications, large-format lithium-ion batteries are being utilized, as large cells have less inactive material relative to their energy capacity and require fewer electrical connections to assemble into packs. And especially for stationary energy storage systems, where energy delivered is the only revenue source, the economics of these battery systems is highly dependent on cell lifetime. However, testing of large-format lithium-ion batteries is time consuming and requires high current channels and large testing chambers, making information on the performance of commercial, large-format lithium-ion batteries hard to come by. Here, accelerated aging test data from four commercial large-format lithium-ion batteries is reported. These batteries span both NMC-Gr and LFP-Gr cell chemistries, pouch and prismatic formats, and a range of cell designs with varying power capabilities. Accelerated aging test results are analyzed to examine both cell performance, in terms of efficiency and thermal response under load, as well as cell lifetime. Cell thermal response is characterized by measuring temperature during cycle aging, which is used to calculated a normalized thermal resistance value that may help estimate both cell cooling needs or to help extrapolate aging test results to different thermal environments. Cell lifetime is evaluated qualitatively, considering simply the average calendar and cycle life across a range of conditions, as well as quantitatively, using statistical modeling and machine-learning methods to identify predictive aging models from the accelerated aging data. These predictive aging models are then used to investigate cell sensitivities to stressors, such as cycling temperature, voltage window, and C-rate, as well as to predict cell lifetime in various stationary storage applications. Results from this work show that cell lifetime and sensitivity to aging conditions varies substantially across commercial cells, necessitating testing for specific cell formats to make quantitative lifetime predictions. That being said, all commercial cells tested here are predicted to reach at least 10-year lifetimes for stationary storage applications. Based on the aging test results and modeling, some cells are expected to be relatively insensitive to temperature and use-case, making them suited for simple use cases with little or no thermal management and simple controls, while the lifetime of other cells could be extended to 20+ years if operated with thermal management and degradation-aware controls.

Book Synopsis Modeling Stationary Lithium-Ion Batteries for Optimization and Predictive Control by :
Download or read book Modeling Stationary Lithium-Ion Batteries for Optimization and Predictive Control written by and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurately modeling stationary battery storage behavior is crucial to understand and predict its limitations in demand-side management scenarios. In this paper, a lithium-ion battery model was derived to estimate lifetime and state-of-charge for building-integrated use cases. The proposed battery model aims to balance speed and accuracy when modeling battery behavior for real-time predictive control and optimization. In order to achieve these goals, a mixed modeling approach was taken, which incorporates regression fits to experimental data and an equivalent circuit to model battery behavior. A comparison of the proposed battery model output to actual data from the manufacturer validates the modeling approach taken in the paper. Additionally, a dynamic test case demonstrates the effects of using regression models to represent internal resistance and capacity fading.

Book Synopsis Modeling and Control of State of Charge of Modular and Second Life Battery Systems by : Yunfeng Jiang
Download or read book Modeling and Control of State of Charge of Modular and Second Life Battery Systems written by Yunfeng Jiang and published by . This book was released on 2019 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to meet the increasing requirements for better utilization of renewable energy technologies, lithium-ion battery energy storage system have currently been developed to power an ever-increasing electrical applications in renewable energy industry and automotive industry. Energy storage capabilities are determined by the battery size, typically expressed in the units from watt hour to megawatt hour. Battery capacity is often fixed and amount of charge is specified in state of charge. If battery is used to plan for long term energy provision, battery size has to be chosen large, making battery energy storage system cost prohibitive. It is necessary to design battery smaller and in modular, but allow them to be exchanged and make sure different modular keep same for state of charge via balancing. In this dissertation, some state-of-the-art modeling and control approaches for battery energy storage system are thoroughly proposed and validated in detail. Firstly, a fractional differential model method is presented for modeling the dynamics of a lithium-ion battery system over a large operating range, which is combination of conventional equivalent circuit model and electrochemical impedance spectroscopy experimental data. The proposed model includes a constant phase element term to approximate the non-linear dynamical behavior of the lithium-ion battery through broad operating range. The continuous-time system identification methods are introduced to estimate model parameters of the proposed fractional differential model. Validated on experimental data obtained from a lithium-ion battery, the estimated model provides better model accuracy and model performance than traditional integer equivalent circuit model methods. Secondly, to better utilize a battery energy storage system, a fractional differential battery modeling approach is proposed to characterize power delivery dynamics, given charge and discharge demand as an input, not only in normal operating range, but also in extreme cases, such as battery over-charging and over-discharging. In particular, the proposed model is combined by individual voltage and current models to predict the dynamics of the energy storage and delivery of a lithium-ion battery system. The continuous-time parameterization and estimation methods are fully described and validated on the experimental data from a lithium iron phosphate battery. Finally, some current scheduling strategies are proposed to solve battery heterogeneity and further improve the performance, lifespan and safety of a battery energy storage system with parallel connected battery modules. The scheduling algorithms are formulated in both open-loop and closed-loop implementation. The open-loop algorithm is formulated by solving a typical linear programming problem with detailed knowledge of the battery system. The closed-loop method is computed autonomously by recursive control algorithm without detailed battery knowledge, even when the characteristic parameters change as the battery pack ages. The experimental results indicate the feasibility and flexibility of the proposed current scheduling method in a battery pack system with parallel placed buck regulated battery modules.

Download or read book Predictive Models of Li-ion Battery Lifetime (Presentation). written by and published by . This book was released on 2014 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predictive models of Li-ion battery reliability must consider a multiplicity of electrochemical, thermal and mechanical degradation modes experienced by batteries in application environments. Complicating matters, Li-ion batteries can experience several path dependent degradation trajectories dependent on storage and cycling history of the application environment. Rates of degradation are controlled by factors such as temperature history, electrochemical operating window, and charge/discharge rate. Lacking accurate models and tests, lifetime uncertainty must be absorbed by overdesign and warranty costs. Degradation models are needed that predict lifetime more accurately and with less test data. Models should also provide engineering feedback for next generation battery designs. This presentation reviews both multi-dimensional physical models and simpler, lumped surrogate models of battery electrochemical and mechanical degradation. Models are compared with cell- and pack-level aging data from commercial Li-ion chemistries. The analysis elucidates the relative importance of electrochemical and mechanical stress-induced degradation mechanisms in real-world operating environments. Opportunities for extending the lifetime of commercial battery systems are explored.
