Abstract. The paper has built 3D-FEA models to simulate the electro-thermal behavior of Li-ion battery cells with Pouch Cell and Prismatic Cell by ANSYS. As for two models, the Li-ion battery system is simplified as a single equivalent battery layer (Pouch Cell) or multiple equivalent battery layers (Prismatic Cell) with the equivalent electrodes and separator. They were simulated under air cooling conditions. Simulations were compared with available battery temperature measurements. This shows that the 3D electro-thermal model applied in this study characterizes the electro-thermal behavior of the Li-ion battery cells reasonably well.

Abstract:
Recently, the use of prismatic cells in electric vehicles has increased significantly. Unlike the cylindrical or pouch format, the prismatic cell format has not been sufficiently investigated. In this study, quasi-static mechanical tests are performed on prismatic cells. The tests include a cylindrical and a hemispherical impactor that mechanically load the cells in all three spatial directions. In both in-plane directions, a cell stack consisting of three cells is tested to capture the influence and loading of the outer cells of a cell stack. It is found out that, in the in-plane tests, short-circuiting occurs first in the outer cells and subsequently in the middle cell, which is targeted by the impactor. This result can also be supported by computed tomography scans. The results illustrate that, when evaluating the crash safety of battery cells, several cells should always be tested in order to capture the different loading of the cells.

Abstract:
The battery pack is the core component of a new energy vehicle (NEV), and reducing the impact of vibration induced resonance from the ground is a prerequisite for the safety of an NEV. For a high-performance battery pack design, a clear understanding of the structural dynamics of the key part of battery pack, such as the battery module, is of great significance. Additionally, a proper computational model for simulations of battery module also plays a key role in correctly predicting the dynamic response of battery packs. In this paper, an experimental modal analysis (EMA) was performed on a typical commercial battery module, composed of twelve 37Ah lithium nickel manganese cobalt oxide (NMC) prismatic cells, to obtain modal parameters such as mode shapes and natural frequencies. Additionally, three modeling methods for a prismatic battery module were established for the simulation modal analysis. The method of simplifying the prismatic cell to homogenous isotropic material had a better performance than the detailed modeling method, in predicting the modal parameters. Simultaneously, a novel method that can quickly obtain the equivalent parameters of the cell was proposed. The experimental results indicated that the fundamental frequency of battery module was higher than the excitation frequency range (0–150 Hz) from the ground. The mode shapes of the simulation results were in good agreement with the experimental results, and the average error of the natural frequency was below 10%, which verified the validity of the numerical model.

Abstract:
The present work provides an overview on an additive manufacturing (AM) design case of a novel battery cell lid structure (patent pending) for electrical vehicle applications. The benefits of AM have not yet been explored on metal case structures of prismatic battery cells. The method allows the manufacturing of complex hollow structures and integration of multiple functions in one part. The main challenge is to address thermal management in an optimal location in the battery cell. More efficient charging and discharging by maintaining the batteries at optimum operating conditions allows a longer battery lifetime. Recent research shows that elevating the charging temperature enables significantly shorter charging times. The aim of this study is to develop a lid structure to support higher peak current, faster charging, and reduced production steps and enable mass customization. The optimum performance simulated with computational fluid dynamics calculations is realized to determine the optimum design. The design case study is verified via laser powder bed fusion prototypes. This study shows that it is possible to produce integrated thermal management liquid channels to the battery lid. Significant improvement is achieved with localized battery cell temperature management. The novel design integrates six critical functionalities of the lid in one part. The design of the features is optimized to avoid support structures in AM and to maximize the number of parts in the printing chamber volume. The better thermal management extends the driving range of the vehicle and improves vehicle safety. Reducing the parts significantly simplifies cell production.

Abstract:
Along with global efforts to reduce the carbon footprint, electrification of powertrains is occurring in various applications, certainly including transportation systems. One of the most important components is an electric energy storage system, i.e., a battery pack. Regardless of battery form factors, such as cylindrical, pouch and prismatic type, it is critical to maintain the safety of the battery module/pack by monitoring the conditions of each and every battery cell of the battery pack. It becomes even more critical as the battery cells are used over many charging and discharging cycles. Thermal runaways of the battery packs can even be triggered by a single faulty battery cell which degrades in an unexpected manner and speed compared to the neighboring battery cells, resulting in extreme fire hazards. Typically, this faulty cell with an abnormally increased internal resistance can be detected using a voltage sensor or a temperature sensor. However, in this study, instead of depending on those sensors, activities of cell balancing switching devices are used to identify a degraded cell compared to other cells in a relative manner. A currently proposed faulty cell detection algorithm was developed through multiple simulations with Matlab Simulink®, then, a simple BMS prototype was built and tested as a proof of concept.

Abstract:
The motivation of this paper is to identify possible directions for future developments in the battery system structure for BEVs to help choosing the right cell for a system. A standard battery system that powers electrified vehicles is composed of many individual battery cells, modules and forms a system. Each of these levels have a natural tendency to have a decreased energy density and specific energy compared to their predecessor. This however, is an important factor for the size of the battery system and ultimately, cost and range of the electric vehicle. This study investigated the trends of 25 commercially available BEVs of the years 2010 to 2019 regarding their change in energy density and specific energy of from cell to module to system. Systems are improving. However, specific energy is improving more than energy density. More room for improvements is thus to be gained in packaging optimization and could be a next step for further battery system development. Other aspects looked at are cell types and sizes. There, a trend to larger and prismatic cells could be identified.

Abstract:
In electric vehicles with lithium-ion battery systems, the temperature of the battery cells has a great impact on performance, safety, and lifetime. Therefore, developing thermal models of lithium-ion batteries to predict and investigate the temperature development and its impact is crucial. Commonly, models are validated with experimental data to ensure correct model behaviour. However, influences of experimental setups or comprehensive validation concepts are often not considered, especially for the use case of prismatic cells in a battery electric vehicle. In this work, a 3D electro–thermal model is developed and experimentally validated to predict the cell’s temperature behaviour for a single prismatic cell under battery electric vehicle (BEV) boundary conditions. One focus is on the development of a single cell’s experimental setup and the investigation of the commonly neglected influences of an experimental setup on the cell’s thermal behaviour. Furthermore, a detailed validation is performed for the laboratory BEV scenario for spatially resolved temperatures and heat generation. For validation, static and dynamic loads are considered as well as the detected experimental influences. The validated model is used to predict the temperature within the cell in the BEV application for constant current and Worldwide harmonized Light vehicles Test Procedure (WLTP) load profile.

Abstract:
The reliable production of high-quality lithium-ion battery components still poses a challenge, which must be met to cope with their rising demand. One key step in the production sequence is the process of cell-internal contacting, during which the electrode carrier foils of the anode and the cathode are joined with the arrester. This is usually done with ultrasonic or laser beam welding. Both joining processes, however, show limitations concerning the quality of the weld. This paper presents a new approach for cell-internal contacting by using micro-friction stir spot welding. Welding experiments were conducted in which joints with high mechanical strengths were produced. It was also shown that large stacks with foil numbers of 100 can be joined in only a few tenths of a second. The process is therefore especially of interest for the fast production of large-scale battery cells or other new types of high-energy-dense battery cells.

Abstract:
Energy systems in every part of the world are experiencing accelerated shifts towards more sustainable solutions which will bring far-reaching changes to our daily lives. These rapid transitions will bring impactful and vital changes to the way we fuel our cars, heat our homes and power our industries in the approaching decades. [1] The automotive sector is in high pace to electrify their cars. The number of electric passengercar sales is expected to increase by more than a factor of 60 between 2018 to 2050. Which means by that time there could be approximately 2 billion EVs on the roads and they all need batteries to run on. [1] ManyEuropean electric vehicle manufacturers have started marketing their future models globally, but automotiveli.-ion battery manufacturing capacity in Europe is merely 2.1% of the total global automotive li-ion batteryproduction. [2] Increase in sales of EV-s and energy storage systems drives the demand for li-ion batteries. This research is conducted in collaboration with Northvolt, one of the newcomers to the li-ion batterymanufacturing market in Europe. Northvolt is a Swedish-founded company in 2016, and despite its young age, Northvolt has prominent partners including BMW Group, Epiroc, Scania and the Volkswagen Group. Northvolt is with global ambition to produce the world's greenest battery cell with minimal possible carbon footprint in its Gigafactory in Sweden with 32GWh annual manufacturing capacity. Also, together with Volkswagen a 50/50 joint venture has been established to produce batteries in a 16GWh factory in Germany. After entering in different supplier agreements, Northvolt has sold a considerable amount of its first Gigafactory NV Ett production capacity to its key customers with a united equivalent of over $13billion until 2030. [3]Setting up lithium-ion battery factories for the automotive industry is a challenging task. It requires high speed and flexibility to keep up with the growing demand in a short time and still meeting all the stakeholder's requirements while keeping the highest environmental standards in place during production. To keep up with the growing demand and customer requirements a state-of.the-art industrialization project management strategy is developed. Therefore, state-of.the-art automotive project management, new product industrialization and development practices are investigated together with the best practices from the wider industry. Furthermore, Northvolt's current industrialization project management strategies are examined, and improvement proposals and tools are developed to ramp-up the current and future factories with shorter time, less cost and highest possible quality. The main aim of the thesis is to develop a project management solutions to lead industrialization of li-ionbattery Giga-factories successfully and help Northvolt fuel our cars, heat our homes, and power our industries more sustainably and innovatively. The expected outcome of the thesis is five tools developed that support the industrialization of LIB production facilities in Europe to increase the EU LIB manufacturing capacity.
Energisystem genomgår en snabb omväxling till allt mer hållbara lösningar, vilket kommer påverka våra liv markant. Dessa snabba omväxlingar kommer påverka samt främja sättet hur vi driver våra bilar, värmer våra hus och försörjer våra industrier, flera år framåt. [1] Bilsektorn som har skiftat sitt fokus till elektrifiering av sina bilar, där antalet sålda elbilar förväntas att öka sextifaldigt mellan 2018 och 2050. Detta kommer att leda till att cirka 2 miljarder elbilar kommer att åka på vägarna globalt och alla dessabilar kommer behöva framförallt litiumjonbatterier. [1] Majoriteten av biltillverkare i Europa har börjatutveckla framtida elektrifierade bilmodeller. Tillverkningen av litiumjonbatterier för elbilar i Europa utgörendast 2.1 % av den globala tillverkningen totalt. [2] En ökad försäljning av elbilar och även av produkterför energilagring, ökar efterfrågan på litiumjonbatterier. Den här undersökningen har tagits fram i samarbete med Northvolt som är en av nykomlingarna inomtillverkningen av litiumjonbatterier i Europa. Northvolt är ett svenskt bolag som startades 2016 och trotsdess tidiga fas, har de lyckats samverka med prominenta samarbetspartners som BMW group, Epiroc, Scania och Volkswagen group. Northvolts ambition är att skapa världens grönaste batteri med ett minimalt klimatavtryck. Denna produkt utvecklas i deras så kallade Gigafactory som ligger i Skellefteå och vars årliga produktion uppnår 32 Gwh. Utöver det har Northvolt i samarbete med Volkswagen fått i uppdrag att bygga upp en batterifabrik i Tyskland, vars tillverkningskapacitet kommer att uppnå till 16Gwh årligen. Efter att ha ingått i flera leverantörsavtal har Northvolt sålt en avsevärd mängd av sin produktionskapacitet för den planerade fabriken Gigafactory NV Ett till sina nyckelkunder. Detta motsvarar en investering på 13 miljarder dollar fram till 2030. [3]Att etablera en fabrik som tillverkar litiumjonbatterier för bilindustrin är en utmanande uppgift. Det kräversnabba beslut och flexibilitet för att hålla jämna steg med den växande efterfrågan på batterier av denna typ. Batterierna ska hålla måttet för de krav som kunderna har, och även ska de uppfylla alla internationella standarder för ett miljövänligt batteri.För att kunna upprätthålla den växande efterfrågan och kundkraven utvecklas nya metoder inom projektledning för att effektivisera produktionen. Det allra senaste praxis i projektledning, produktion och produkttillverkning inom bilindustrin analyseras. Dessutom beaktas senaste metoderna och praxis från andra industrier. Vidare kartläggs northvolts nuvarande strategi för deras hantering av produktionsfasen för att föreslå förbättringar och verktyg, som kan effektivisera uppbyggnaden och driften av framtida fabriker. Huvudsyftet med denna avhandling är att utveckla nya metoder inom projektledning för att kunnautveckla produktionsfasen för framtida fabriker som tillverkar litiumjonbatterier. Detta kommer leda tillatt Northvolt kommer vara en del av våra framtida liv genom att hjälpa oss att driva våra fordon, värma våra hem och driva våra fabriker på ett hållbart och effektivt sätt. Det förväntade resultatet i denna avhandling är fem utvecklade verktyg som stödjer utbyggnaden av Litiumjonbatteri fabriker i Europa föratt öka dess totala årliga produktion.

Abstract:
Batteries are promising sources of green and sustainable energy that have been widely used in various applications. Lithium-ion batteries (LIBs) have an important role in the energy storage sector due to its high specific energy and energy density relative to other rechargeable batteries. The main challenges for keeping the LIBs to work under safe conditions, and at high performance are strongly related to the battery thermal management. In this study, a critical literature review is first carried out to present the technology development status of the battery thermal management system (BTMS) based on air and liquid cooling for the application of battery energy storage systems (BESS). It was found that more attention has paid to the BTMS for electrical vehicle (EV) applications than for stationary BESS. Even though the active forced air cooling is the most commonly used method for stationary BESS, limited technical information is available. Liquid cooling has widely been used in EV applications with different system configurations and cooling patterns; nevertheless, the application for BESS is hard to find in literature.To ensure and analyze the performance of air and liquid cooling system, a battery and thermal model developed to be used for modeling of BTMS. The models are based on the car company BMW EV battery pack, which using Nickel Manganese Cobalt Oxide (NMC) prismatic lithium-ion cell. Both air and liquid cooling have been studied to evaluate the thermal performance of LIBs under the two cooling systems.According to the result, the air and liquid cooling are capable of maintaining BESS under safe operation conditions, but with considering some limits. The air-cooling is more suitable for low surrounding temperature or at low charging/discharge rate (C-rate), while liquid cooling enables BESS to operate at higher C-rates and higher surrounding temperatures. However, the requirement on the maximum temperature difference within a cell will limits the application of liquid cooling in some discharge cases at high C-rate. Finally, this work suggests that specific attention should be paid to the pack design. The design of the BMW pack is compact, which makes the air-cooling performance less efficient because of the air circulation inside the pack is low and liquid cooling is more suitable for this type of compact battery pack.

Abstract:
This work developed a novel experiment in order to determine the operational effects on a Lithium-ion battery (LIB) when a test resulting in non-catastrophic damage is performed. Accepted industry standards were used as a basis to develop a nail penetration test that would puncture a cell approximately halfway through during normal cycling at a rate of 1C, then allow the cell to continue cycling to determine how its operation was affected. The cells under test continued cycling after the punctures, showing that the experiment would be able to provide useful information on the topic. The experiment was found to be successful in simulating the operation of a cell in an abusive environment, such as those seen in electric vehicles and aerospace applications.

The results of these experiments showed that a sharp increase in temperature is observed immediately after the puncture, similar to cells that underwent tests with full penetrations. The temperatures then slowly decreased during the first few cycles after the puncture as the generated heat was dissipated through convection. The experiments also showed that it is possible for a LIB under test to continue operating for a short time after being punctured. However, the capacity and useful life of the cells were greatly reduced. The initial capacity of each cell decreased by approximately 11% after the initial impact, then continued decreasing at an accelerated rate during the ensuing cycling. The lifetime of the cells was also greatly reduced, with each cell reaching its end of life within approximately 15-75 cycles after the punctures. An analysis of the incremental capacity curves of the cells indicated that accelerated aging occurred due to both a loss of active material and a loss of lithium inventory. The information gained from the experiments gives insight into the operation of cells that experience abusive environments and will be useful in designing improved control systems, as well as promoting the development of more robust testing and safety standards for different types of cells.

Abstract:
The temperature distribution in a prismatic Li-ion battery cell can be described using a spatially distributed equivalent circuit electrical model coupled to a 3D thermal model. The model represents a middle ground between simple one or two state models (generally used for cylindrical cells) and complex finite element models. A lumped parameter approach for the thermal properties of the lithium-ion jelly roll is used. The battery is divided into (m × n) nodes in 2-dimensions, and each node is represented by an equivalent circuit and 3 temperatures in the through plane direction to capture the electrical and thermal dynamics respectively. The thermal model is coupled to the electrical through heat generation. The parameters of the equivalent circuit electrical model are temperature and state of charge dependent. Parameterization of the distributed resistances in the equivalent circuit model is demonstrated using lumped parameter measurements, and are a function of local temperature. The model is parameterized and validated with data collected from a 3-cell fixture which replicates pack cooling conditions. Pulsing current experiments are used for validation over a wide range of operating conditions (ambient temperature, state of charge, current amplitude and pulse width). The model is shown to match experimental results with good accuracy.

Abstract:
Li-ion batteries are today considered the prime solution as energy storage system for EV/PHEV/HEV, due to their high specific energy and power. Since their performance, life and reliability are influenced by the operating temperature, great interest has been devoted to study different cooling solutions and control algorithms for thermal management. In this context, this paper presents a computationally efficient modeling approach to characterize the internal temperature distribution of a Li-ion battery cell, conceived to serve as a tool to aid the design of cooling systems and the development of thermal management systems for automotive battery packs. The model is developed starting from the unsteady heat diffusion equation, for which an analytical solution is obtained through the integral transform method. First, a general one-dimensional thermal model is developed to predict the temperature distribution inside a prismatic Li-ion battery cell under different boundary conditions. Then, a specific case with convective boundary conditions is studied with the objective of characterizing a cell cooled by a forced air flow. To characterize the effects of the cooling system on the temperature distribution within the cell, the one-dimensional solution is then extended to a 1+1D model that accounts for the variability of the boundary conditions in the flow direction. The calibration and validation of the specific model presented will be presented, adopting a detailed 2D FEM simulator as a benchmark.

Abstract:
Abstract A three-dimensional analysis of an 8s1p (8 series and 1 parallexl batteries in a stage) lithium-ion battery module consisting of 8 prismatic batteries is performed using a multi-domain modeling framework. The well-known Newman, Tiedemann, Gu, and Kim (NTGK) model is used for modelling. A thermal management system based on liquid cooling via cold plates utilizing glycol aqueous solution (GAS) is proposed. Cooling simulations of the battery module are carried out at different GAS volume concentrations and flow velocities. The temperature evolutions at different volume concentrations and inlet flow velocities are determined, and the results are found to be in good agreement with the experiments. Strategies for modifying the properties of GAS to release the heat generated by the battery module are proposed. It is found that, the cell temperature and temperature gradients were maintained at a tolerable level at a suitable inlet flow velocity and volume concentration of GAS, even at a 5C discharge rate. The simulation and experimental results demonstrate that the temperature difference between the 8 battery cells reaches the minimum when the volume concentration of GAS is 70%, which means that the optimum cooling uniformity of the battery module can be reached at this volume concentration.

Abstract:
Abstract Lithium-ion (Li-ion) batteries have recently become the main source of power in portable devices due to advantages such as high energy density. However, Li-ion cells operate well only in a specific temperature range. Degraded preperformance is a consequence of low temperature operation, and potential fire risk originates from thermal runaway at elevated temperatures. Efficient thermal management of Li-ion cells and battery packs is essential to ensure safe and durable performance in wide temperature range. Thermoelectric coolers (TECs), which have been used widely for electronics cooling may also be appropriate for battery cooling due to size compactness, working with direct current. This paper presents experimental characterization of cooling of a prismatic test cell with TECs on two sides. Cooling effect of TEC on the cell core and surface temperatures is investigated at different TEC power rates. Results show core and surface temperatures of the test cell decrease significantly. The obtained results show that by applying the TEC, a temperature drop of 10 °C was achieved for 0.75A TEC current. The optimum TEC current can be selected based on the application. In addition, numerical simulations are carried out to compare with experimental measurements. Heating effect of mounted TECs can be easily achieved just by changing current direction. Experimental results reveal TECs can heat up a cell in cold climate shortly. In addition, thermo electric module may also offer insulating effect in cold climate. Results presented in this paper illustrate potential application of thermoelectric cooling for thermal management of Li-ion cells.

Abstract:
Abstract Due to the high-power efficiency of lithium-ion batteries, there is an increased interest in integrating batteries into vehicles to create a more sustainable transportation method. However, batteries require thermal management systems to maintain heat generation within ranges lower than 40 kJ and operation temperatures between 25°C and 40°C. When exposed to extremely high or low temperatures, the battery efficiency decreases, and adverse consequences may occur. To combat this, research is conducted to explore various options to create thermofluidic systems that utilize fluids to regulate the battery pack’s temperatures. Developments in cooling systems have commonly used air as the cooling fluid, but research in recent years is innovating towards liquids to encourage a higher heat dissipation rate. This paper introduces battery thermal management system applications, current technologies and challenges, and innovations for improving existing models. The current technologies discussed involve manufactured systems based on air- and liquid-cooling for cylindrical and prismatic battery cells. We provide information on new engineered fluids for improvements in fluid properties. In addition to this, new directions related to manufacturing techniques or materials are highlighted to showcase potential changes to current systems to integrate complicated cooling channels in a three-dimensional design. This paper thereby aims to summarize the holistic view showing the direction of the field and possible techniques for battery thermal management.

Abstract:
Lithium-ion (Li-ion) rechargeable batteries are used as one of the major energy storage components for implantable medical devices. Reliability of Li-ion batteries used in these devices has been recognized as of high importance from a broad range of stakeholders, including medical device manufacturers, regulatory agencies, patients and physicians. To ensure a Li-ion battery operates reliably, it is important to develop health monitoring techniques that accurately estimate the capacity of the battery throughout its life-time. This paper presents a sparse Bayesian learning method that utilizes the charge voltage and current measurements to estimate the capacity of a Li-ion battery used in an implantable medical device. Relevance Vector Machine (RVM) is employed as a probabilistic kernel regression method to learn the complex dependency of the battery capacity on the characteristic features that are extracted from the charge voltage and current measurements. Owing to the sparsity property of RVM, the proposed method generates a reduced-scale regression model that consumes only a small fraction of the CPU time required by a full-scale model, which makes online capacity estimation computationally efficient. 10 years’ continuous cycling data and post-explant cycling data obtained from Li-ion prismatic cells are used to verify the performance of the proposed method.

Abstract:
Thermal propagation test of lithium-ion battery is an important method to verify the safety of battery system, and how to effectively trigger the thermal runaway of a cell and minimize the energy introduced into the system become the key of test method design. In this work, the influence of different heating area and different heating power on thermal runaway of prismatic cells and pouch cells is studied. The results show that when the heating area is fixed, the heating power increases, the heating time required to trigger the thermal runaway of the cells becomes shorter. The energy needed to be introduced becomes smaller, but there will be a minimum value of the introduced energy. On the other hand, the thermal runaway results of prismatic cells are more sensitive to the change of heating area, and the thermal runaway results of pouch cells are more sensitive to heating power.
