Mercedes EQC 4Matic 2021 charging cable

From the 2020 model year, the Mercedes-Benz EQC 400 4MATIC received an upgraded 11 kW three-phase onboard charger, replacing the earlier 7.4 kW two-phase unit. The 80 kWh usable battery and dual-motor all-wheel drive carry over, along with a WLTP range of up to 269 miles. Connected to a three-phase supply, the updated EQC adds roughly 31 miles of range per hour and completes a full charge in around eight hours. The CCS charging port sits on the right rear flank, in the same position as the fuel filler on a conventional GLC.

The cable that unlocks the upgraded charger

Most UK homes supply single-phase power to the wallbox. On that connection, a Voldt® Type 2 charging cable rated at 22 kW is the practical choice for the updated EQC. Its conductors carry 32A per phase, allowing the cable to pass the full 7.4 kW a single-phase wallbox delivers on one line. The 80 kWh battery charges completely in around twelve hours at that rate, comfortably inside an overnight window. An 11 kW cable, rated at 16A per phase, would limit the same wallbox to 3.7 kW: roughly half the speed and a full charge stretching past twenty hours. At public and workplace chargers that supply three-phase power, both cables deliver the car's 11 kW ceiling equally, so owners who already have a three-phase wallbox at home can choose the 11 kW cable as the direct match and the more economical option.

The charging port on the right rear flank mirrors a fuel filler position: reversing into a bay places the port closest to the charge point. A 6-metre cable handles most home driveways. Eight metres is the reliable everyday length for home and public charging alike. A 10-metre cable adds useful reach where the post sits further from the bay, and 15 metres covers longer driveways, hotel car parks, and less predictable public layouts without restriction.

Portable charging on the road

A Voldt® portable charger with a red three-phase commando plug connects to 16A three-phase CEE sockets and delivers the EQC's full 11 kW. A complete charge takes around eight hours on the 80 kWh battery. Red CEE sockets are found at workshops, industrial units, farm buildings, and marinas: anywhere a three-phase supply runs to an accessible outlet, this charger matches the speed of a dedicated home wallbox. The current is adjustable between 8A and 16A, so you can dial it down to suit the supply.

The Voldt® blue CEE portable charger connects to the 16A single-phase sockets fitted at campsites and caravan parks, charging at 3.7 kW. Over a multi-night stay it steadily rebuilds range and keeps daily driving comfortable without a detour to a public rapid charger. The Voldt® three-pin portable charger plugs into any standard UK domestic socket at up to 2.8 kW, within the limits of what the household wiring can sustain. Connected overnight at a relative's house or a holiday let, it restores a meaningful share of the next day's driving range. A built-in thermal sensor tracks the plug temperature throughout the charge and reduces the current automatically if the connection warms up, protecting both the vehicle and the wiring.
