The document discusses aging modeling for lithium-ion battery packs used in hybrid and electric vehicles. It presents an empirical capacity loss model developed within the AMESim simulation platform to predict battery degradation over time based on factors like temperature, current and state of charge. The model accounts for both cycling and calendar aging modes. Experimental validation shows the model can accurately simulate capacity fade from a PHEV duty cycle up to a state of health of 80%. Simulations examine the impact of different vehicle usage strategies, like always storing the battery fully charged versus just-in-time charging before use, on predicted battery lifetime.

To showcase of the co-simulation capabilities between LMS Imagine.Lab Amesim and STAR-CCM+, Siemens PLM Software presents this feature through a study of the thermal and airflow characteristics in an avionics equipment bay.
The bay geometry is simplified, and the fluid flow within the bay is simulated in STAR-CCM+. The thermal characteristics of electronic cards (contained in their enclosures) are simulated in LMS Amesim, especially the heat generation due to the consumption of electrical power.
The study demonstrates the advantages that can be had from co-simulating two powerful software packages, respectively specializing in the system simulation and CFD domains.

Prediction of li ion battery discharge characteristics at different temperatu...eSAT Journals
Abstract State of charge (SOC) is an important battery parameter which provides a good indication of the useful capacity that can be derived out of a battery system at any given point of time. Li-ion has become state of the art technology for commercial and aerospace applications due to the various advantages that they offer. For spacecrafts requiring long lifetime, SOC estimation is crucial for on-orbit as well as offline data analysis. On-orbit estimation of SOC should be carefully addressed, as this provides information on survivability of battery and also serves as input to Battery Management System (BMS). In addition, detailed offline data analysis of battery electrical characteristics, which indicate the SOC-Voltage relationship is important to assess the performance of the battery under various mission scenarios at both Beginning of life (BOL) and End of Life (EOL) of a spacecraft system. In this work, a hybrid SOC estimation method, incorporating coulomb counting and Unscented Kalman Filter (UKF) is used, to predict the BOL discharge behaviour of an 18650 commercial Li-ion cell at different temperatures and discharge rates. The experimental results are encouraging and the approach gives a prediction error of less than 10%. The study will serve as basis for life assessment of Li-ion cells and batteries used for GEO and LEO missions. Key Words: Li-ion, State of Charge, Unscented Kalman Filter etc…

At PreScouter, we help Fortune 500 clients quickly get up-to-speed on what they need to know to understand their options. PreScouter's Inquiry Service is a new, custom approach to ask science-based questions with a Ph.D. researcher through a brief video call. The results are debriefed in a meeting within two business days. This app provides clients with technically relevant, actionable information to further business objectives on a recurring basis.
In this inquiry, a client needed to identify Pre-Series B (or research teams) in the battery space that has a proprietary technology. PreScouter found 13 different batteries. Very soon, we should see a massive change in the ability to safely store and release power. Batteries explored include, but are not limited to: solid-state lithium-ion batteries, magnesium batteries, graphene car batteries, laser-made micro-supercapacitors, Na Ion batteries, and one of the fastest battery packs, LumoPack. PreScouter concluded this R&D injury with suggested next steps.
Electric vehicles (EVs) coupled with low-carbon electricity sources offer the potential for
reducing greenhouse gas emissions and exposure to tailpipe emissions from personal trans-
portation. In considering these benefits, it is important to address concerns of problem-
shifting. In addition, while many studies have focused on the use phase in comparing
transportation options, vehicle production is also significant when comparing conventional
and EVs.
An electric circuit model for a lithium-ion battery cell based on automotive ...IJECEIAES
The on-board energy storage system plays a key role in electric vehicles since it directly affects their performance and autonomy. The lithium-ion battery offers satisfactory characteristics that make electric vehicles competitive with conventional ones. This article focuses on modeling and estimating the parameters of the lithium-ion battery cell when used in different electric vehicle drive cycles and styles. The model consists of an equivalent electrical circuit based on a second-order Thevenin model. To identify the parameters of the model, two algorithms were tested: TrustRegion-Reflective and Levenberg-Marquardt. To account for the dynamic behavior of the battery cell in an electric vehicle, this identification is based on measurement data that represents the actual use of the battery in different conditions and driving styles. Finally, the model is validated by comparing simulation results to measurements using the mean square error (MSE) as model performance criteria for the driving cycles (UDDS, LA-92, US06, neural network (NN), and HWFET). The results demonstrate interesting performance mostly for the driving cycles (UDDS and LA-92). This confirms that the model developed is the best solution to be integrated in a battery management system of an electric vehicle.
Removing carbon from the processes which are essential to our modern world will be one of our generation's defining challenges. Central to this goal will be the role of Energy Storage within our modern infrastructure. Energy storage will need to be placed at all parts in our infrastructure - both in front and behind the meter applications will be key. These diverse applications will need a portfolio of technologies to deliver services to a range of customers. In this talk we explore some innovation possibilities with a focus on (a) Li-ion roadmap and the role of digitisation, (b) Flow batteries for longer term storage and finally (c) Power2X technologies for Energy Reserve and Chemical Industry.
Today power electronics play an important role in the electric industry. Power electronic converters are an inseparable component in power systems. One of these converters is DC/AC inverter that is widely used in power systems, industrial applications, electric motor drive and electric vehicles. Due to the tense situation with the complexity that exists in these applications, inverters are exposed to failure. The fault occurring in inverter can cause disturbance and damaging harmonics, cut some industrial processes to in the power system or in the case of electric vehicles, causing irreparable damage. For this reason, detecting faults in the inverter is very important. In this paper, open circuit fault of IGBT in an electric vehicle has been examined. We use three-phase current and wavelet transform to identify the state of the system and we can extract current waveform characteristics. We use neural network algorithm for fault detection and classification. An electric vehicle in 5 different speeds and 5 different torque and a total of 220 failure modes have been studied and tested. The results show the method has been succeeded to detection all forms of defined faults.
