Master Thesis Project
Title: Adaptive battery modelling and algorithm development for electrified vehicles
China-Euro Vehicle Technology CEVT is making a significant step towards the electrification of cars. Batteries are a crucial component making this transition possible. To ensure safe and optimal usage of the battery, an adaptive model of the studied battery is imperative. Meanwhile, the importance to develop intelligent estimation and control algorithms is also axiomatic.
The overall aim of the thesis work is to build up a state-of-the-art online implementable battery model and intelligent control algorithm.
- Conduct a thorough literature study to understand different models and estimation algorithms for vehicle battery cells
- Perform battery cell testing at the Chalmers Battery Lab to characterize the cell during the vehicle lifetime
- Calibrate typically equivalent circuit models based on the experiment data, in which sensitivity analysis and nonlinear optimization techniques will be employed.
- Based on the existing literature methods, program cell-level online estimation algorithms for State of Charge, open-circuit voltage, internal resistance, state of health, and state of power.
- Implement and evaluate the above model-based estimation algorithms on a battery-in-the-loop platform.
Students recruited for this project will have the opportunity to work closely with the battery team, CAE energy team at CEVT and the Sustainable Energy Control team (SECL) within the Automatic Control group at Chalmers. SECL has two professors, one researcher, one postdoc (an additional two under recruitment), and five PhD students currently working on BMS. We will have regular group meetings and activities to discuss projects and share knowledge in a stimulating, inclusive, and collaborative team environment. Lab training and support will be offered along with the project.
- Master student in Electrical/Control Systems Engineering
- Interest in vehicle electrification
- Basic knowledge in Matlab and Simulink or Python
- Basic knowledge in electrical/battery experiments
- Basic knowledge in system identification and state estimation (e.g., Kalman filters)
Number of students: 2, please apply with CV and cover letter.
Starting date: January 2022. The duration of the thesis work is 20 weeks and the work will be carried out at CEVT headquarters in Lindholmen, and the cell testing will be conducted at Chalmers battery lab.
