Thesis Worker: Model based predictions of battery state of health
Thesis Worker at Volvo Cars
Welcome to explore the world of Volvo Cars by writing your thesis with us! As a thesis worker in our organization, you are supported by a supervisor who follows you during your project. All thesis projects are arranged in business-critical areas and therefore you will be able to contribute to our company purpose – providing freedom to move in a safe, sustainable, and personal way – from day one!Background
With the rapid development of electrification, the ageing of Li ion batteries has received increased attention in recent years. With the battery being the largest and most expensive component in a Battery Electrified Vehicle (BEV) the understanding of battery ageing is critical to both the sustainability and the profitability of any BEV. Battery lifetime is also a key attribute for the car customers, affecting the second-hand value and expected lifetime of the vehicle. These aspects make it highly important to be able to monitor, follow up and make forecasts of the battery state-of-health (SOH) in the customer fleet.The goal of this thesis project is to evaluate models best suitable for predicting battery SOH until end of life on both individual cars as well as for the entire customer fleet.
Scope
As Master thesis student you will be working on development of prediction methods for usage of batteries. You will have the opportunity to cooperate with colleagues within the Battery Hardware Department, other supporting departments as well as various stake holders for battery SOH. You will be part of a highly motivated team working with field data where there is strong interest in creating new insights.In the master thesis project ‘Model based predictions of battery state of health’ you will be working on analysing field data with focus on battery SOH. The project will build on previous studies on car fleet SOH and knowledge/data from cell testing with the aim to identify models suitable for battery SOH estimations. To reach further there is a need to get a deeper understanding of how the vehicle data can be used to predict battery SOH and how the SOH data itself should be interpreted and used in the best way. There is also a need to take on a more holistic approach on the model identification, where both data driven approaches as well as data from cell testing are taken into consideration and compared.
