1. Mesoporous Materials for Fast Charging Electrochemical Energy Storage
Sammanfattning : High performing electrochemical energy storage (EES) devices are needed to cope with the increasing energy requirements of modern society. Electrode materials must store lots of energy, charge/discharge fast and be environmentally friendly. LÄS MER
2. Durability Aspects of Fast Charging, Mechanical Constraint, and Inhomogeneity in Lithium-Ion Batteries
Sammanfattning : The development of lithium-ion batteries with higher energy and power density, better safety, and lower cost has significantly contributed to the increased market share of electric vehicles (EVs) in the last decade. However, the expectations of end-users of EVs still require a continuous quest for better performance. LÄS MER
3. Identifying Parameters for Aging-Adaptive Battery Management
Sammanfattning : The modern transportation system is largely based on fossil fuels. To reduce this reliance on oil and gas and thereby drastically reduce emissions, a transition to renewable power sources is necessary. Lithium-ion batteries are the most established candidate for electromobility applications, with suitable energy and power densities. LÄS MER
4. Modelling, parameter identification and aging-sensitive management of lithium-ion batteries in heavy-duty electric vehicles
Sammanfattning : The battery is a component with significant impact on both the cost and environmental footprint of a full electric vehicle (EV). Consequently, there is a strong motivation to maximize its degree of utilization. Usage limits are enforced by the battery management system (BMS) to ensure safe operation and limit battery degradation. LÄS MER
5. Interpretable Battery Lifetime Prediction Using Early Degradation Data
Sammanfattning : Battery lifetime prediction using early degradation data is crucial for optimizing the lifecycle management of batteries from cradle to grave, one example is the management of an increasing number of batteries at the end of their first lives at lower economic and technical risk. In this thesis, we first introduce quantile regression forests (QRF) model to provide both cycle life point prediction and range prediction with uncertainty quantified as the width of the prediction interval.
