Our expertise covers the design and production of advanced embedded electronics technologies for the mobility ecosystem. We develop innovative solutions such as transmission control units (TCUs), vehicle control units (VCUs), hydrogen control units (HMUs) and IoT devices. Our expertise also extends to power electronics: high-performance motor inverters and embedded chargers. These cutting-edge technologies optimise the efficiency and reliability of modern propulsion systems, paving the way for more sustainable and intelligent mobility.

As part of the GCK Group, GCK EMI benefits from the group’s extensive expertise in developing solutions tailored to market needs.
We thus draw on the expertise of the various entities in the field of equipment and vehicles: GCK Mobility (retrofitting of heavy vehicles), GCK Performance (prototyping and small series of vehicles), Solution F (powertrain and systems) and GCK Battery (lithium-ion batteries). We also put our expertise at their service as a supplier of embedded electronics components and technologies.
Our real strength lies in our integrated industrial ecosystem with entities offering complementary expertise, capable of working independently on complex issues while creating powerful, comprehensive solutions together.
