Mercedes E 400 e Charging cable

The Mercedes-Benz E-Class PHEV (W214) is an executive plug-in hybrid available as a Saloon and an Estate, with petrol and diesel powertrain options. The petrol variants are the E 300e (230 kW / 313 PS, rear-wheel drive, 0–100 km/h in 6.8 seconds), the E 300e 4MATIC (230 kW / 313 PS, all-wheel drive, 0–100 km/h in 6.5 seconds), and the E 400e 4MATIC (280 kW / 381 PS, all-wheel drive, 0–100 km/h in 5.7 seconds). The E 300de 4MATIC pairs the same electric motor with a 2.0-litre diesel engine. All variants share the same 25.4 kWh gross battery (19.5 kWh usable), 11 kW three-phase AC onboard charger, and WLTP electric range of between 95 and 115 km depending on variant. A 55 kW DC rapid charging option is available. The Type 2 charging port is located on the left rear flank.

Battery and electric range

The lithium-ion battery is integrated into the floor of the vehicle and provides a WLTP electric range of up to 115 km for the E 300e, with the 4MATIC and E 400e variants returning up to 109 km due to the additional weight of the all-wheel-drive system. The diesel E 300de achieves a similar WLTP range. In all cases the electric motor delivers 440 Nm from rest, and the car defaults to electric-only mode at startup, switching to the combustion engine for higher loads or depleted battery. Electric driving is possible at speeds up to 140 km/h.

Charging at home and at public wallboxes

The 11 kW three-phase onboard charger fills the 19.5 kWh usable battery from empty in approximately two hours at a compatible three-phase wallbox or public AC point. At a single-phase 7.4 kW supply with a correctly rated cable, the same charge takes approximately three and a half hours. For faster charging away from home, the optional 55 kW DC connection brings the battery from 10% to 80% in approximately 20 minutes. A full 0–100% DC charge takes around 40 to 45 minutes once the battery management system's end-of-charge taper is accounted for.

Choosing the right cable

With an 11 kW three-phase onboard charger, an 11 kW Voldt® Type 2 cable is the correct match at any three-phase wallbox or public Type 2 point. On a single-phase home wallbox (7.4 kW), however, 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, a full charge takes around five and a half to six hours instead of three and a half. A 22 kW cable, with 32A-per-phase conductors, carries the full single-phase load and delivers 7.4 kW. For owners with a single-phase home installation, a 22 kW cable is the practical choice: it covers both home and public scenarios without compromise and future-proofs for any vehicle with 22 kW AC charging.

Length: finding the right fit

The charging port is on the left rear flank on both the Saloon and Estate, so reversing to the wallbox is the most practical approach at home, keeping the cable short and off the vehicle's paintwork. A 6-metre cable suits most home driveways and garage configurations. For public charging, an 8-metre cable handles the variation in post positions and bay layouts across different stations. For greater reach, 10 and 15-metre options are available, and Voldt® supplies cables up to 40 metres for dedicated or commercial installations.

Portable charging with a CEE charger

The Voldt® portable CEE charging cable extends charging options to any location with an industrial socket. On a 16A three-phase CEE socket (11 kW), a full charge completes in approximately two hours, matching the speed of a home wallbox. A 32A three-phase CEE socket (22 kW available) delivers the same 11 kW rate, as the car's onboard charger caps at 11 kW. On a 16A single-phase CEE socket (3.7 kW), a full charge from empty takes approximately five and a half to six hours.

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 and result in the five-and-a-half to six-hour charge time noted above. For a battery of this size, a campsite overnight stop is entirely practical at that rate. On a standard domestic socket at 2.3 kW, a full charge takes around eight and a half to nine hours, making an overnight plug-in at home a straightforward option when no wallbox is available.
