R&D Team Lead

Your role and responsibilities

You will be part of Powertrain & Digitalization team at ABB Corporate Research in Västerås, Sweden. At Corporate Research we lead the innovation within ABB and our task is to ensure ABB's technology competitiveness now and in the future. We work in close collaboration with other research centers, our business areas: Motion, Process Automation, Robotics & Discrete Automation and Electrification, as well academic and industrial partners. In our creative and highly skilled team we develop, design, build and test new concepts and prototypes of physical and digital powertrains consisting of electric energy source, electrical motor, electric drive, and a selected application. Electrical systems rely more and more on energy storage, where batteries are seen to introduce new challenges when integrated into larger systems. To study different kinds of batteries, without costly investments and installations, one can emulate a battery using a Hardware-in-the-loop (HIL) system. The HIL system includes power converters controlled to imitate the behavior of the desired load, eg. a battery, and can be changed simply by altering the implemented load model. This introduces many possibilities within R&D, while eliminating the safety concerns when working with electrochemical batteries. Details: • Period: January-June 2025 • 30 ECTS per student • Number of students: 1 • Location: On site at ABB Corporate Research in Västerås, Sweden Your responsibilities: • Literature review on battery modeling and converter control • Static and dynamic modeling of the electrical behavior of a battery • Simulation using a suitable control algorithm to make a power converter mimic the voltage-current characteristics of the modelled battery • Implementation of the control algorithm in a Hardware-in-the-loop (HIL) system • Result analysis and evaluation • Reporting and results dissemination

Qualifications for the role

Electrical Engineering (or similar)
Interested in power electronics and control
Familiar with concepts such as diodes, thyristors, IGBTs and PI-control
