Mercedes EQC 4Matic 2021 charging cable

From the 2020 model year, the Mercedes-Benz EQC 400 4MATIC received an upgraded onboard charger, stepping up from 7.4 kW to 11 kW three-phase. The 80 kWh usable battery remains the same, but the faster charger reduces the full charge time considerably at a compatible three-phase supply. At a three-phase wallbox or public charge point, the EQC adds approximately 50 km (31 miles) of range per hour. The CCS Type 2 inlet sits on the right rear flank, behind the passenger door.

Which charging cable fits the Mercedes-Benz EQC 400 4MATIC 2020–2021

An 11 kW Voldt® Type 2 charging cable is the correct match for the updated EQC, delivering the car's full AC charge rate at any compatible three-phase wallbox. A 22 kW cable works equally well at 11 kW and is worth considering if you plan to use it with a higher-capacity vehicle in the future.

On a single-phase home wallbox (7.4 kW), an 11 kW three-phase cable bottlenecks the session to 3.7 kW, as its conductors are rated at 16A per phase rather than the 32A a single-phase wallbox delivers on one line. At 3.7 kW, the 80 kWh battery takes around 25 to 26 hours for a full charge. A 22 kW cable, whose conductors are rated at 32A per phase, carries the full single-phase load and delivers 7.4 kW, reducing that to approximately 12 to 13 hours. For owners with a single-phase home installation, a 22 kW cable is the practical choice.

The right-rear port mirrors the position of a conventional fuel filler, so reversing into a bay puts the port closest to the post. An 8-metre cable is the comfortable everyday standard for mixed home and public use. A 10-metre cable is the practical choice for stress-free parking in any orientation. A 15-metre cable removes all doubt on longer driveways and unpredictable hotel car parks.

Portable charging for travel and outdoor use

The Voldt® portable CEE charging cable connects to industrial CEE sockets and is available up to 22 kW via three-phase CEE. For the 2020–2021 EQC, output is capped at the car's 11 kW onboard charger ceiling regardless of socket rating. On a 16A three-phase CEE socket (11 kW), the 80 kWh battery charges fully in around eight and three-quarter hours. On a 32A three-phase CEE socket the result is the same, as the car accepts no more than 11 kW.

Red three-phase CEE sockets are found at industrial sites, workshops, and some commercial marinas. Standard European campsite hookup points use blue single-phase 16A CEE sockets, which cap output at 3.7 kW. At that rate, a full charge from near-empty takes around 25 to 26 hours. A campsite blue socket is adequate for a partial top-up during a multi-night stay, but not a practical source for a full charge on a single overnight stop. On a standard domestic socket at 2.3 kW, a full charge takes around 41 hours: relevant only as an emergency fallback over multiple days, not a regular charging method for a battery of this size.
