**Thesis - Survival Analysis for HV Battery Failures**:
**Master Thesis**:
The automobile industry's transition to electric vehicles is accelerating, with this paradigm shift, the efficiency and reliability challenges for these complex physical systems are increasing. Since the battery is the most important component in an electric vehicle, we would like to enable the possibility for predictive technical actions based on available fleet data. Therefore, the aim of this master thesis is, to use of state-of-the-art survival analysis techniques, in order to develop a statistical model, which can estimate the remaining lifetime of the battery for a certain failure type.

**TASK**:

- Research on the state of the art survival analysis algorithms
- Examination of possible influencing patterns and failure effects which can be used to predict the remaining battery lifetime
- Implementation of data processing routines and feature engineering algorithms
- Development of a survival model to predict the remaining lifetime of the individual battery
- Possibility to combine weibull and proportional hazard models (e.g., cox)
- Investigation and implementation of proper performance metrics to assess the quality of the developed models
- Investigation and implementation of a suitable model validation approach
- Assessment of the trade-off between the amount of data, model performance and computational time

**REQUIREMENTS**:

- Attended lectures on the topic of survival analysis
- Strong proficiency in Python
- Highly developed quality awareness
- Strong attention to details

**PREFERRED FIELD OF STUDY**:

- Applied Statistics
- Computer Science
- Technological Mathematics

Annual Remuneration: Due to the Austrian Equal Treatment Act we are obligated to state the annual gross remuneration (full-time) for this position as a basis for negotiation: €2.500,00. We will, in any case, offer market-conforming payment taking qualifications and professional experience into account.
