Hyundai EV Service, Maintenance & Repair

The Ioniq 5 and Ioniq 6 run on E-GMP, an 800-volt platform that charges faster than almost anything at the price — and asks more of a workshop than most. EVS UAE services it properly, including the ICCU and onboard charging faults that generic garages misread.

About Hyundai.

Hyundai's E-GMP platform did something unusual: it brought 800-volt charging, vehicle-to-load power output and a genuinely fast charge curve down to a mainstream price. The trade-off is a more complicated electrical architecture. The integrated charging control unit in particular is a known weak point across the Ioniq range, and it presents as a car that will not charge or suddenly loses 12-volt power. Diagnosing it correctly takes brand-level tools, not a code reader.

Frequently Asked Questions.

Most often the integrated charging control unit. It is a known fault across the Ioniq range and it also shows up as a flat 12-volt battery, so the two get confused. We test both before replacing anything.

It needs different isolation procedures and different test equipment to a 400-volt car. We are set up for it.

Yes. The Kona uses a 400-volt system rather than E-GMP, and it is covered alongside the Ioniq models at EVS Dubai.
