SUMMARY:Dissertation - Leonardo Colombo
DESCRIPTION:Thesis title: “Iron Losses\, Measurement and Characterization in Stator Cores”. \nSummary of the thesis \nDriven by the global transition towards energy-efficient electrical machines\, iron loss computation remains a complex challenge. Because material composition\, manufacturing\, and mechanical stress heavily influence ferromagnetic behaviour\, accurate prediction is notoriously difficult. This thesis advances the field by investigating soft magnetic stator cores and related measurement techniques.\nStatistical comparisons of different measurement techniques on specimens from the same batch reveal statistically significant differences. Tests on custom-manufactured toroidal cores reveal approximately frequency-independent core loss build factors up to 400 Hz\, when compared to the material datasheet. The research also presents a custom-built core loss tester using a switch-mode\, rather than linear\, power amplifier\, enabling higher-power\, stable PWM excitation of inductive loads without impedance matching. It supports both sinusoidal-flux and PWM tests\, achieving accuracy comparable to a commercial system for hysteresis loops and total core losses. \nExperimental data is mapped using the Jiles-Atherton (JA) hysteresis model\, optimized across multiple induction levels rather than a single saturation point as commonly found in the literature. While a dynamic JA formulation (integrating Bertotti’s loss separation) yields superior accuracy\, the original magnetostatic formulation remains remarkably viable above quasi-static frequencies. Finite Element Method (FEM) simulations integrating the static JA model show strong agreement with the analytical optimization results. The application of the JA model in simulating electrical machines is exemplified by analyzing the peak-torque operating point of a permanent magnet machine at a low excitation frequency. For this case\, a modified JA formulation capable of accurately modelling deep saturation magnetisation characteristics is introduced\, yielding good agreement with alternative modelling approaches and aligning with the machine’s nominal datasheet values for peak torque. Insights on the influence of multi-level Pulse-Width Modulation (PWM) on iron losses are presented via reconfiguration of the in-house core loss tester to emulate cascaded H-bridge converters. Increasing the amplitude modulation ratio and switching frequency effectively dampens PWM-induced losses. Most notably\, as the number of PWM voltage levels increases\, characteristic minor hysteresis loops vanish\, transforming into a high-frequency ripple. This confirms the in-house setup as a highly effective tool for initial investigations of how different converter architectures impact the losses in soft magnetic materials. \nFor more information\, visit Lund University calendar

SUMMARY:Theme (4) Environment and Society seminar – Final readiness and considerations for Battery Passport launch
DESCRIPTION:The EU Battery Passport will become mandatory for electric vehicle batteries and other large batteries placed on the European market from February 2027. \nWhile the overall regulatory framework is now in place\, significant implementation challenges remain for companies across the battery value chain. Battery pack suppliers and vehicle OEMs are currently working to interpret still evolving requirements related to data collection\, information governance\, interoperability\, confidentiality\, and access rights. \nThe Battery Passport represents a major shift towards transparency and traceability\, but many practical questions regarding data formats\, system integration\, and responsibilities between stakeholders still lack clear answers. This workshop provides a forum for SEC partners and researchers to discuss uncertainties\, share experiences\, and explore pathways towards successful implementation. \nAgenda\n– Introduction to Battery Passport requirements\, Annika Ahlberg Tidblad\, Volvo Cars \n– Challenges in the implementation of the Battery Passport\, Emelie Dymling\, Zeekr Technology Europe \n– Group discussions in break-out sessions \n– Summary of discussion and joint learnings \nMost welcome! \n  \nDate           4 December\nTime          08:45–10:30\nLocation    Online – registered participants will receive the Teams link after registration has closed \n  \nPlease click HERE to register for the seminar. \nRegister by 2 December.

SUMMARY:Dissertation - Godwin Peprah
DESCRIPTION:Thesis title: Modelling and Real-Time Predictive Control for Hybrid Cooling of Lithium-Ion Batteries \nAbstract: \nSurface cooling offers a large heat-transfer area\, while tab cooling can reduce internal temperature gradients by exploiting the high thermal conductivity of battery current collectors. This thesis investigates how these complementary cooling approaches can be integrated through modelling and predictive control. \nReduced-order two-dimensional thermal models are developed to reproduce the spatial temperature field at low computational cost. Building on these models\, a real-time model predictive control framework dynamically distributes coolant between the battery tabs and lateral surface. The proposed approach closely reproduces nonlinear model predictive control while reducing the mean computation time from several seconds to approximately 19 ms. The framework is further extended to account for battery degradation and spatial temperature non-uniformity\, reducing degradation-model computation by more than 20 times. Overall\, integrated tab-surface cooling achieves the best balance among temperature regulation\, thermal uniformity\, battery degradation\, and coolant use. \nFor more information\, visit Chalmers University of Technology calendar
