Internship_Electric Vehicle (EV) battery management current sensing solution_4 to 6 months - Bevaix, Switzerland





Permanent employment opportunity after the internship

Project description

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.

Expected results

  • 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

Your profile

  • Self-motivated student, eager to learn, curious, and enterprising with a strong problem-solving mindset

  • Strong experience with electrical measurements and characterization in a lab environment

  • (Strong) experience with embedded C/C++. Python and Git (GitLab) are a plus

  • Experience with Altium is a plus

  • Experience with Creo or any CAD software is a plus

We offer

  • A challenging internship in a dynamic high-tech international environment

  • An enjoyable, team-oriented  and professional  atmosphere in a flat-structured organization

  • Versatile development opportunities

Melexis Current sensing branch has increased significantly in the past few years, closing projects with major OEMs such as Tesla (X/S/3/Y), Renault (ZoƩ, E-TECH), or BYD. Supported by the growing electrification of vehicles, Melexis is expanding its current sensing branch: upon excellent work and strong motivation, this Master Thesis may lead to a permanent position offer.
