Tessenderlo (BEL) or Bevaix (CH) – 4 to 6 months

Subject: Electric Vehicle (EV) battery management current sensing solution

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 test

        Develop a working HV battery setup in our HV lab

Requirements

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

        Strong experience with electrical measurements and characterization in a lab environment
