Project overview

Mission Senior BMS Test Engineer (EIS) H/F

Us

Avel Technologies is a French engineering and technology consulting company, specializing in embedded systems and software development.

Our client is an international player in the semiconductor sector, developing advanced solutions for battery management systems (BMS).

The mission context:

Within an R&D team based in Toulouse, you will be involved in the validation and characterization of new BMS solutions for high-voltage battery cells, modules, and packs.

The mission specifically focuses on the development of automated test benches based on Electrochemical Impedance Spectroscopy (EIS), the validation of current excitation systems using DC/DC converters, and the evaluation of battery state estimation algorithms.

The mission:
