Master Thesis - Virtual Testing for Electric Drive Units

Infinite motion for the future"
InfiMotion Technology develops, manufactures, and sells high performance electric drive units for fully electric vehicles, addressing the whole value chain, including production software and single components.

InfiMotion was founded in 2021 in Wuxi, China, and lead investors are companies such as Geely Auto, Lotus and Ningbo Luma, with a professional board of directors with experienced powertrain and automotive executives from well-known Geely Holding companies.

By the end of 2022, InfiMotion aims to have 700 experienced employees across two R&D Centers in Gothenburg Sweden and in Wuxi China. The InfiMotion team has been responsible for over two million sold units to date, by which over 90 000 were delivered to the European market. The first batch of new high-performance products will go into production in late 2022.

Title: Development of a FPGA based Signal Level Hardware in the Loop Rig for Virtual Testing

Background:

InfiMotion Technology Europe is developing state of the art high performance Electric Drive Units (EDUs) including the Software. In general, an EDU is composed of an inverter, an electric machine (EM), and a transmission. Among these, the “Intelligence” lies in the Inverter/Power Electronics (P.E.) via control strategies and optimisation patterns to efficiently run the EM. Developing sophisticated controls results in robust verification and validation requirements which is a key element of the V Cycle development. We at InfiMotion are utilizing Hardware in the Loop (HiL) rigs for virtual testing and calibration and are continuing to develop our testing capabilities with state-of-the-art FPGA based signal level HiLs.

Scope:

The overall aim is to setup a FPGA based Signal level HiL and integrate an in house Inverter controller (PCB) in a closed loop testing environment.

Goals:

- Explore the current and future trends of P.E. HiL testing from literature
- Investigate FPGA technology for HiL testing - current and future direction
- Perform qualitative analysis/ comparison between processor based and FPGA based Plant model simulations on Signal level HiLs
- Investigate EM/ Inverter modelling toolchain with various suppliers supporting FPGA
- Develop FPGA targetted models for EM and Inverters
- Integration of plant models with the device under test (the PCB) on the HiL rig
- Support physical installations and documentation of HiL including I/O devices, wirings and harnesses, etc.
- Perform validation tests cordinating with the Software team to verify the control software


Prerequisites:

- Master student in Electrical Engineering, Automotive Engineering, or Similar
- Ability to take initiative, work independently with good communication skills
- Good knowledge of power electronics, inverters, and electric machines
- Good knowledge of modelling and simulation
