Research and development · Zagreb

We repair what the automotive industry replaces!

An institute for EV, PHEV and ICE research and repair. We take the pack, the drive unit and the inverter down to the cell, the winding and the die, and we publish what we find.

Scale · Cell

One bad cell should not cost a car.

A dealer reads a fault code, sees a pack out of balance and quotes a replacement. We open the pack, measure every cell, and change the ones that failed.

Diameter

Height

Nominal
3.700 V

Scale · Silicon

The fault is in the die, not the module.

An inverter is condemned because one IGBT shorted. The module is a sealed assembly nobody sells separately, so the whole unit is scrapped. We go to the die, the bond wires and the substrate, and we stock the parts.

Device
IGBT / SiC MOSFET
Substrate

Junction
175 °C

Scale · Machine

A drive unit is not a sealed box.

Stator, rotor, bearings, resolver, gearbox. Each fails in its own way and each leaves its own signature. We rebuild the ones the manufacturer replaces whole.

Machine
PMSM / induction
Windings
Hairpin and round
Insulation
Tested to 5 kV

Scale · Module

The margin lives inside the pack.

Busbars, the cooling ribbon, the sense harness and the balancing electronics. Most of what goes wrong in a pack is not the chemistry.

Scale · Pack

Repair is the cheaper engineering, not the lesser one.

A skateboard pack is four modules, an enclosure, two drive units and the high-voltage distribution between them. Replacing it is a purchasing decision. Repairing it is an engineering one.

Scale · Network

What we work out here, the network does everywhere.

Procedures, tooling and parts go out to every centre through the Academy. One building does the research; the map below is where it lands.

Headquarters

Four things this building does.

01

Research

Failure modes nobody has documented, worked out on the bench and written up. What we learn becomes a procedure in the Academy.

02

Analysis

Every cell measured, every winding tested, every die inspected. A fault code narrows the search; it does not end it.

03

Reverse engineering

Closed BMS firmware, undocumented CAN, parts that exist only inside a sealed assembly. We open them and publish the map.

04

Production

Repair kits, diagnostic hardware and replacement electronics, built here because nobody else makes them.

The network

Where we are, and where we are not.

Every centre and every territory still open, live from headquarters in Zagreb. A dashed outline means the master licence for that country is unclaimed.

Repairs

What we repair, and what it costs.

All repairs

Get started

Four ways in.

Book a repair

Send the defective component, not the vehicle. Intake form, brand and model, and a description of the fault.

Start intake →

File service

Remote BMS and ECU resets. Fault cleared against your own file, returned the same day where the case is known.

Browse resets → evclinic.eu
