Thesis - Self-supervised Learning for Battery Health Estimation f/m/d
Aufgaben:
We are looking for a motivated student to conduct their master thesis in the area of Li-ion batterie modelling using state-of-the-art machine learning modelling techniques. This master thesis focuses on developing advanced techniques to estimate the health estimation of battery health and performance in the automotive industry. By leveraging deep neural network architectures for learning the trajectory of the degradation with existing amount of test data, the aim is to estimate the state-of-health without having the entire history of the battery's operation (zero-shot learning). The thesis will contribute to the overcome practical issues for SOH estimation in-field and will offer valuable insights into understanding the influencing aging factors.
Literature research: Identify the state-of-art for the specific applications and rank most relevant architectures/techniques
Data preparation and pre-processing: Utilize time series analysis and aggregation techniques to create a pipeline for feature engineering during charge cycles. Selection of the target variables
Data segmentation: Prepare sample of data from existing experimental datasets for training the models
Comparison and ablation study: Establish a set of baseline methods (i.e., MLP, RNN, LSTM) that will be used for comparison purposes
Final model evaluation: Utilize the trained models for final evaluation in both experimental and real-world data
Sensitivity analysis: Utilize Explainable-AI methods to pinpoint influencing factors and explain model's outputs
Qualifikationen:
BSc in domains similar to Applied Statistics/Mathematics, Computer Science, Data Science, Automotive or Electrical Engineering
Strong background in data analysis, deep learning, and time series prediction
Proficiency in programming languages such as Python for implementing data analysis algorithms
Familiarity with statistical methods and transformers (LLMs)
Ability to work independently, conduct experiments, and analyze complex data sets
Excellent problem-solving and critical-thinking skills
Strong communication skills to present findings and recommendations effectively
