Mercedes A250 PHEV charging cable

The Mercedes-Benz A 250e is a plug-in hybrid compact available in two body styles: the five-door hatchback (W177) and the four-door saloon (V177). Both share the same third-generation EQ Power drivetrain, combining a 1.33-litre four-cylinder turbocharged petrol engine with a 75 kW electric motor for a combined output of 218 hp and 450 Nm, routed through an 8-speed dual-clutch gearbox to the front wheels. A 15.6 kWh lithium-ion battery sits beneath the rear seats, delivering a WLTP electric range of 56–70 km (35–44 miles), with 0–100 km/h in 6.6 seconds for the hatchback and 6.7 seconds for the saloon.

The A 250e hatchback was introduced in 2019 alongside the saloon variant, with a facelift following in 2023 that brought updated styling and infotainment but left the powertrain and charging architecture unchanged. All model years and both body styles charge identically, and the guidance below applies to the full production run.

The charging inlet is a Type 2 socket on the right rear flank of the vehicle. The onboard AC charger accepts up to 7.4 kW on a single phase. Some cars were optionally equipped with a DC charging pack adding CCS2 capability at up to 24 kW, enabling a 10–80% charge in around 25 minutes, though this was a paid option not fitted as standard in all markets.

Home and public charging

At 7.4 kW from a wallbox, the A 250e charges from 10% to 100% in approximately 1 hour 45 minutes, as stated by Mercedes-Benz. In daily use, most drivers top up from a partial state rather than starting from empty, so a typical charge session is considerably shorter. A standard 7.4 kW single-phase wallbox matches this car well.

Connecting to an 11 kW or 22 kW three-phase wallbox does not increase the charging rate, since the A 250e's onboard charger is single-phase and draws no more than 7.4 kW regardless of supply capacity.

Cable choice

With a 7.4 kW single-phase onboard charger, an 11 kW Voldt® Type 2 cable is the correct match for the A 250e at home and at any public AC charge point. It handles the car's full 7.4 kW charging capability and connects to every Type 2 wallbox and charge point built to the IEC 62196-2 standard.

A 22 kW cable is equally well suited to the A 250e and adds forward compatibility for any future vehicle with an 11 kW or 22 kW three-phase onboard charger. Both options perform identically on this car.

How long a cable do you need?

A 6 metre cable covers the majority of home wallbox setups, giving enough reach from a wall-mounted charger to the right rear inlet without excess cable on the ground. For public charging stations, where the position of the charge post relative to the bay may vary, an 8 metre cable provides the flexibility to connect comfortably regardless of how the car is parked.

Portable charging with a CEE charger

The A 250e's 15.6 kWh battery is compact enough to make portable charging a practical option wherever industrial CEE sockets are available, such as at workplaces, campsites, or event venues. The Voldt® portable EV charger connects via a Type 2 plug on the vehicle side and a CEE plug on the supply side, and is available in models covering 3.7 kW through to 22 kW.

The A 250e has a single-phase onboard charger, so it draws from one phase only, regardless of how many phases the socket provides. A 16A three-phase CEE socket delivers the same 3.7 kW as a 16A single-phase socket, since only one of the three phases is used. Approximate full-charge times from empty:

• 32A three-phase CEE (22 kW socket): the car's 7.4 kW ceiling applies, giving approximately 2 hours 10 minutes.
• 16A three-phase CEE (11 kW socket): single-phase draw at 3.7 kW, giving approximately 4 hours 15 minutes.
• 16A single-phase CEE (3.7 kW socket): 3.7 kW, giving approximately 4 hours 15 minutes.

The 32A three-phase portable charger is the most versatile choice for a household or fleet that includes both single-phase PHEVs and three-phase BEVs, reaching the full charging ceiling of each vehicle.
