Advanced physicochemical modelling of lithium ion batteries for electric vehicles (3084)
Target group: Product Development, Materials Engineering
At Research and Development you will be a key contributor to the next generation outstanding luxury cars from Volvo. Together with other engineers around the world, you and your team will create innovative human-centric car technology that makes life less complicated and more enjoyable for people. Are you interested in design and connected car technology? Do you share our passion for people, the environment and our urge to create a superior driving experience? Research and Development is the place for you to prosper.
This thesis work will be carried out within the Department of Propulsion Energy Systems, which is a part of VCC´s Research and Development organization.
We are dedicated to electrify our brand in a broad effort with Plug-In Hybrids (PHEVs) and Battery Electric Vehicles (BEVs). At the engineering department of Propulsion Energy Systems, we are responsible for design and delivery of the technical solution of Traction Battery systems for electrified vehicles. We cover the complete product development of mechanical, electrical and software. We are the core competence center in Northern Europe in regards to Lithium Ion technology and automotive battery systems.
Volvo Cars Controls & Calibration group is a new group focused on the SW functionality and the Li-Ion expertize for the Traction Battery, used in electrified vehicles. We are taking major steps in taking SW-development In-house and performing more In-house calibration to reach improved results. Much of the In-house SW is based on novel, advanced control systems that needs experienced engineers to calibrate.
Background
Lithium-ion batteries play an important role today in mobility of the future. To use this energy storage optimally complex physical-electrochemical models are necessary, these models provide an insight into the internal state variables of lithium-ion batteries which are impossible to measure otherwise, to analyze the systems behavior in advance and understand the underlying mechanism which lead to battery aging. In this thesis, an physical-electrochemical model shall be implemented for next generation lithium-Ion battery.
With this, it is possible to spatially resolved thermal and electrical behavior of lithium-ion batteries and packs. An important point is the aging behavior of battery under load. This has to be theoretically and based on existing data experimentally investigated for various stressors which can then be associated to corresponding degradation.
Scope
For this purpose, in this thesis, the basic processes of the battery operation shall be modelled as well as parameterized with material data extracted from existing cell test data.
Finally, the application possibilities of the model shall be illustrated by simulating effects observed in aging tests to validate the underlying theories. The parameterized model will enable optimum operation even under extreme conditions such battery under heavy load during extreme temperatures (hot/cold) or during fast charging.
The students will work in the Traction battery department together with our teams of Controls & Calibration Engineers and SCRUM SW team. Weperform system level SW development and simulations.
