Mercedes-Benz has renamed the standard of German craftsmanship with the transparent exhibit of the EQC 400 4Matic, a regular EQC on the left half but with transparent cuts on the other side which reveal the battery and other integral systems of the EV to explain the technological innovations implemented in the car, which can now be observed with the naked eye, using LED chase lights and a virtual overlay of the battery on a tablet are part of the exhibit to be as simple as possible.

Trainees taken from vehicle mechatronics specialists, interior fitting specialist, construction mechanic and tool mechanics worked on the project. The forty odd people came from Sindelfingen, Bremen and Rastatt plants. The team worked for around an year, with halts because of the worldwide pandemic restrictions and converted the donor EQC and body shell into the evocative exhibit today. The trainees were able to gain unparalleled learnings from the unique project.

The exhibit is not just a solid structure but is laden with multiple LED chase lights and other indicating illumination throughout the transparent portions to simulate visually how the battery of the EQC is charged or discharged. The screens inside the EQC were reprogrammed into playing images and videos regarding the systems of the car and how they function. A tablet PC on the exhibit site also displays an Augmented Reality rendering a virtual overlay of the high-voltage charging and energy distribution on the EQC.

The exhibit has extensive use of LED fibre optic cables, about 15 metres of it and more than 50 metres of wiring to provide the power source for the LEDs. Eight grinding discs were used to cut 5 apertures in the body which took 36 hours to complete, which required 23 woven abrasive belts to deburr the edges. Two Arduino microcontrollers were installed for controlling the LED strips and the LED display on the charging socket, the controllers required 500 lines of programming.

The COVID resulted in about 650 minutes of online conferencing to coordinate and plan and a visit of the digital shopfloor management system daily for 20 minutes. The screens used mini-PCs made by Intel to reprogramme them using 1500 lines of code. The project is unique and showcases the labour and skill of the trainees at Mercedes-Benz, laying testimony to their skill in building of EVs and modifications.
