Internship_Electric Vehicle (EV) battery management current sensing solution_4 to 6 months - Bevaix, Switzerland
Permanent employment opportunity after the internship
As an intern at Melexis, you will be engineering current sensor solutions for automotive EV battery applications.
More specifically, you will:
Develop a battery state monitoring solution based on a voltage, current, and temperature (V-I-T) sensor.
Model a Battery Management System (BMS) and explore how sensing accuracy impacts the battery state estimation.
Manage sensor voltage isolation for 400V and 800V state-of-the-art EV batteries.
Develop software for compensation of sensing imperfections.
Make, validate and integrate prototypes that accurately measure V-I-T variables in our HV lab.
- Develop a clear understanding of the BMS and BDU (Battery Disconnect Unit) application
- Develop working shunt and Hall current measurement prototypes compliant with industry requirements
- Develop software, compile and verify it through rigorous tests
- Develop a working HV battery setup in our HV lab
