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
In Electric Vehicles (EVs), High-Voltage components interact in a complex manner. The switching in power electronics generated ripple and generates electromagnetic fields, disturbing other components and degrade their performance. So, it is essential to understand and design components from early stage of the project to reduce price and decrease the development time.
In order to design the and develop electronic components, it is important to know the system impedance of the high-voltage system used for the vehicle propulsion. The impedance is needed from low frequencies up to high frequencies in the EMC range. With the measurements it is possible to create circuit models that can be used to optimize the driveline and electric power system. Also, the impedance of the High-Voltage battery is an important variant that can be used to estimate the state of the battery, state of charge, life expectancy and such. However, the methods and instruments currently available are developed to measure the impedance of the Low-voltage system, battery cell modules and small battery packs and not for the EVs High-Voltage system/battery pack which is rated up to 800V.
Scope
The objective of the thesis work is to investigate different methods to measure the High voltage system and /or battery impedance.
