Available in PDF, EPUB and Kindle. Book excerpt: The unparalleled performance of lithium-ion batteries (LIBs) is driving the ongoing trend of vehicle electrification. However, expanding performance expectations continue to extend the list of "and problems" that require one battery technology to perform many roles that often conflict with each other and are impractical with existing materials. Recently, battery structure modification for internal heating has enabled rapid and efficient thermal modulation of battery performance. This structure, termed the self-heating battery (SHB), achieved restoration of power levels practical for plug-in hybrid electric vehicle batteries in -40 °C ambient conditions. What's more, when adopted for pre-heating to an elevated temperature, 10-minute extreme fast charging was enabled without sacrificing lifetime. In this dissertation, the SHB structure is studied for its applicability to electric vehicle LIBs, which conventionally meet energy density requirements for long range at the cost of stifled power performance. This serves to expand the generality of SHB application at ultra-cold temperatures (e.g., -50 °C) and, overall, the rate capability of existing and next-generation battery materials. Heating rates from ~0.5 °C/s to greater than 1 °C/s are demonstrated, quickly enabling delivery of at least ~50% of RT energy and power, as opposed to almost zero without thermal modulation. Following this, the impact of thermal modulation for improved safety and simplified thermal management is explored from a fundamental perspective. The analysis supports the development of heat-resistant batteries that rest safely in a dormant state during non-operation and are "woken up" for operation by thermal modulation for high power. This paradigm shift in battery design and operation simultaneously enables cooling simplification by enlarging the temperature difference driving heat transfer and reducing the rate of heat generation. Motivated by the broad impact of thermal modulation, the SHB design is revisited to discover an opportunity to reduce overall energy consumption by integrating the requisite switching device to share its generated heat with the battery materials for mutual thermal management. Design guidelines are established and implemented to demonstrate a prototype integrated SHB (iSHB). Through experimental and numerical investigation, iSHB heating performance and lifetime comparable to the legacy structure are elucidated. The SHB -- and now iSHB -- mark the disruption of the more than 200-year-old conventional battery structure, making a passive system active to surrender control of performance to the system designer and make previously unsolvable "and problems" tractable.

This book was released on 2012 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fully coupled electrochemical and thermal model for lithium-ion batteries is developed to investigate the impact of different thermal management strategies on battery performance. In contrast to previous modeling efforts focused either exclusively on particle electrochemistry on the one hand or overall vehicle simulations on the other, the present work predicts local electrochemical reaction rates using temperature-dependent data on commercially available batteries designed for high rates (C/LiFePO4) in a computationally efficient manner. Simulation results show that conventional external cooling systems for these batteries, which have a low composite thermal conductivity (≈1 W/m-K), cause either large temperature rises or internal temperature gradients. Thus, a novel, passive internal cooling system that uses heat removal through liquid-vapor phase change is developed. Although there have been prior investigations of phase change at the microscales, fluid flow at the conditions expected here is not well understood. A first-principles based cooling system performance model is developed and validated experimentally, and is integrated into the coupled electrochemical-thermal model for assessment of performance improvement relative to conventional thermal management strategies. The proposed cooling system passively removes heat almost isothermally with negligible thermal resistances between the heat source and cooling fluid. Thus, the minimization of peak temperatures and gradients within batteries allow increased power and energy densities unencumbered by thermal limitations.

Download or read book An Integrated Methodology for EV oriented Lithium ion Battery Rate of degradation Modeling and Region based Control written by Ruxiu Zhao and published by . This book was released on 2018 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates the physics-based modeling and active control schemes of the lithium-ion battery rate-of-degradation (ROD) for EV applications. An integrated methodology is proposed. It models battery electro-thermal responses during drive cycles, and analyzes different drive cycle current properties' effect on battery ROD during drive cycles. Also, it simplifies the complicated lithium-ion battery ROD model to a reduced-order model suitable to dynamically estimate battery ROD during drive cycles, and develops the active degradation control methodology via controlling the ROD for lithium-ion batteries. A power-commanded lithium-ion battery electro-thermal model combining a recurrent neural network (RNN) electrical model with a lumped thermal model is developed to model battery electrical-thermal responses. Current properties associated with drive cycles such as current rate, the current RMS value, the presence of regeneration and their interactions with the temperature are experimentally analyzed. A reduced-order battery ROD model without partial differential equations (PDE) with accurate exchange current estimations is developed. Active degradation control schemes during drive cycles via controlling the ROD are developed, incorporating the proposed models and emphasizing on manipulating the aging factors associated with the drive cycle current properties. Trade-off between the degradation reduction and battery performance compromise is addressed and an adjustable ROD-limit boundary is proposed to help achieve better balances. The ROD control system is also integrated with conventional battery state estimation systems to extend the overall battery management system capability. This research lays a foundation for applying active degradation control based on ROD control for lithium-ion batteries during drive cycles. This work can be valuable for EV applications for extending the battery life while maximizing the battery performance.

This book was released on 2016 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lithium ion batteries are instrumental in tackling the challenges of global warming. They have shown great utility in electric and hybrid vehicles. However, challenges with regard to performance and safety such as capacity fade and thermal runaway need to be accounted for in the implementation of these battery systems. One way is through battery management systems that monitor and control various aspects of the battery’s operation. At the heart of the battery management system is an analytical model of the battery. This thesis proposes a battery management system which uses a “lowuses a “low-order” physics- based battery model that estimates capacity and optimally manages the temperature of the battery. A capacity estimation methodology is proposed that uses the state of charge estimate from an extended kalman filter and the inverse of the coulomb counting equation to estimates the “instant” capacity of the battery. This instant value is then used in an averaging calculation that uses saturation limits and a time delay to obtain a value for the capacity that is representative of the battery. This value is then feedback into the kalman filter. The capacity estimate obtained through this method was between 2 and 8 % off of the true value. A thermal management system is also proposed that optimally controls a fan to cool a lithium ion battery. The thermal management system was developed and tested in a simulated environment. First, the fan model was integrated with the battery model and simulations were run to test the open loop temperature response of the battery to the fan cooling while varying the input voltage of the fan the current demanded of the battery. From this data an operating point was chosen, the system was linearized, and a linear quadratic controller was designed and implemented. The controller was sluggish when faced with a temperature perturbation in the absence of a current demand increase but drove the temperature change to zero. In the presence of a current change controller drove the state to a nonzero steady state value. The same result occurred when a disturbance rejection mechanism was applied to the controller.

Available in PDF, EPUB and Kindle. Book excerpt: "Lithium ion batteries have been widely used in consumer electronics and are beginning to move to the forefront of the automotive and power grid industries. Lithium ion batteries are desirable in these applications because they are high energy density and high specific energy cells, while remaining inexpensive and lightweight. Safety is a concern in every consumer application; therefore, in order for lithium ion battery use to continue growing, advances in battery management systems are needed. Thermal management of lithium ion batteries is currently a critical issue. Applications are becoming more dependent on active liquid thermal management systems. The development of precise battery active liquid thermal management systems begins with an accurate temperature model applicable to control design. This work is focused on the development of a dynamic active liquid cooled battery cell thermal model through the coupling of a lumped energy balance and a single particle electrochemical heat generation model. A fluid channel is added to the bottom of the cell and an aluminum heat sink is added to the side of the cell. Results demonstrate that fluid temperature has more effect on the cell temperature than fluid mass flow rate. The dynamic model developed in this work has an order of 135 and; therefore, is not applicable to controller design. Linearization about an equilibrium trajectory and model order reduction via the Global Arnoldi Algorithm (GAA) is applied. Results show good agreement between the first order reduced system and the non-linear system"--Abstract, leaf iv

Available in PDF, EPUB and Kindle. Book excerpt: Integrated Vehicle Health Management (IVHM) is a relatively new subject, with its roots back in the space sector of the early 1990s. Although many of the papers written around that time did not refer to it as IVHM, the fundamental principles of considering an integrated end-to-end system to monitor the overall health of the asset were clearly visible. As the subject of Integrated Vehicle Health Management (IVHM) and its associated technologies have grown up, businesses are making the transformation from selling a product to selling a service. This can be viewed as a positive disruption, as a relatively small technology breakthrough is being brought to market for a large business benefit. The sequence “sense—acquire—transfer—analyze—act “ feeds the information (processed data) on the asset’s health into the Operations or Management control center. Here, decisions can be made on maintenance actions with knowledge of the supply chain status, MRO loading, etc., provided by Maintenance and Logistics systems. Undoubtedly, a much more efficient and economical modus operandi.

Download or read book Modeling Temperature Distribution in Cylindrical Lithium Ion Batteries for Use in Electric Vehicle Cooling System Design written by Samuel Anthony Jasinski and published by . This book was released on 2008 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advancements in lithium ion battery technology have made BEV's a more feasible alternative. However, some safety concerns still exist. While the energy density of lithium ion batteries has all but made them the premier electric vehicle (EV) battery choice, their potential to overheat and explode is a limiting factor. Beyond certain temperature thresholds, lithium ion batteries will experience what is known as thermal runaway. During thermal runaway, the temperature of the battery increases uncontrollably and fires and explosions can occur. For this reason, adequate thermal management is a necessity in bringing lithium ion battery powered vehicles to market. The purpose of this work is to 1) develop mathematical models for temperature distribution and heat transfer in cylindrical lithium-ion cells and battery packs, 2) derive the target heat transfer coefficient for an EV cooling system 3) analyze the key design parameters of EV thermal management systems, and, ultimately, 4) determine the method of cooling necessary to prevent thermal runaway. The models are based on the fundamentals of heat transfer and are integrated into computer simulations for testing. Based on the models developed in this analysis, forced convection at the surface of the battery pack is not sufficient for preventing thermal runaway outside of minimum operational requirements (low ambient temperatures and discharge rates). For typical vehicle usage, a system in which the working fluid penetrates the pack is needed. There may be potential for a hybrid cooling system: one that relies on surface convection for less strenuous operation and strategically placed cooling channels for typical and extraneous operation.
