Mercedes GLE 350e Charging Guide: Home Charging, Public Charging and Cable Selection

The Mercedes GLE 350e is a petrol plug-in hybrid version of the Mercedes-Benz GLE, documented in European W167 SUV and C167 SUV Coupé form for the 2020 to 2023 period. It is important to treat this model carefully because the GLE plug-in hybrid range includes several similar-sounding versions, including the GLE 350 de diesel plug-in hybrid and the newer GLE 400 e petrol plug-in hybrid. Current Mercedes-Benz UK new-car listings do not show a new GLE 350e; instead, they list GLE 350 de and GLE 400 e variants with different charging specifications.

For owners and used-car buyers, the key point is to check the exact badge, VIN and charge port before assuming which cable or charging speed applies. The 2020-2023 European Mercedes GLE 350 e 4MATIC is generally associated with a large plug-in hybrid battery, Type 2 AC charging up to 7.4 kW, and optional CCS DC rapid charging where the vehicle is fitted with the correct inlet. This guide explains how to charge it at home and in public, how to choose a suitable Type 2 cable, and why model identification matters.

Mercedes GLE 350e Battery and Charging Specifications

The GLE 350e is a plug-in hybrid electric vehicle, not a full battery-electric vehicle. It combines a petrol engine with an electric motor and a rechargeable high-voltage battery. When charged regularly, it can cover many local journeys using electric power, while the petrol engine provides flexibility for longer trips.

Vehicle type	Petrol plug-in hybrid SUV / SUV Coupé, depending on market and listing
Model context	2020-2023 European-market Mercedes GLE 350 e 4MATIC W167/C167
Battery capacity	31.2 kWh gross; around 27.0 kWh usable in SUV data sources
AC charging	Type 2, single-phase, up to 7.4 kW on the older GLE 350e specification
DC charging	CCS Combo 2 up to 60 kW where the optional DC charging function is fitted
WLTP electric range	Typically quoted around 52-66 miles depending on body style, equipment and source

Because the UK GLE plug-in hybrid line-up has changed over time, do not automatically apply current GLE 350 de or GLE 400 e charging figures to an older GLE 350e. In particular, newer GLE plug-in hybrids may advertise 11 kW AC charging, while public data for the 2020-2023 GLE 350e indicates up to 7.4 kW AC.

Battery Options

For the 2020-2023 Mercedes GLE 350 e 4MATIC SUV, public technical data lists a 31.2 kWh gross battery capacity and around 27.0 kWh usable capacity. That is large for a plug-in hybrid of its era and is one reason the vehicle can offer a meaningful electric-only range when charged frequently.

The GLE 350e Coupé is also listed with a 31.2 kWh gross battery in public data. Usable capacity is not always published consistently for the Coupé, so it is best not to assume a different battery specification unless it has been confirmed for the individual vehicle.

As with any plug-in hybrid, the practical benefit of this battery depends on charging routine. If the car is rarely plugged in, it will still operate as a petrol hybrid, but it will not deliver the same electric-mileage benefit that makes the plug-in version attractive.

AC Charging Speed

For the older European-market GLE 350e, Type 2 AC charging is the main day-to-day charging method. Public data for the 2020-2023 GLE 350 e 4MATIC lists single-phase AC charging between 2.3 kW and 7.4 kW, with a full charge on a 7.4 kW wallbox taking around 195 minutes in the referenced data.

In practical UK terms, a 7.4 kW home wallbox is a strong match for this vehicle. A 32 amp single-phase Type 2 cable is sufficient for the car’s quoted AC limit. Using an 11 kW or 22 kW Type 2 cable will not make a 7.4 kW single-phase GLE 350e charge faster, although a higher-rated cable may be useful if you also own, or later switch to, another EV with higher AC capability.

At many UK public destination chargers, the post may be rated at 7 kW, 11 kW or 22 kW. The vehicle and charger negotiate the actual power, so the GLE 350e will normally charge only up to its own onboard AC charging limit rather than the maximum rating printed on the charging post.

DC Rapid Charging Speed

One unusual feature for a plug-in hybrid is that the GLE 350e can support DC rapid charging where the optional CCS charging hardware is fitted. Public data lists DC charging up to 60 kW and a rapid-charge session of roughly 20 minutes for a typical 10-80% style charge window. However, this should not be treated as universal across all cars.

Before planning around rapid charging, physically check the charge port. A Type 2-only inlet has the upper Type 2 socket only. A CCS Combo 2 inlet has the Type 2 section plus two larger DC pins below it. If the lower CCS pins are not present, the car cannot use CCS rapid chargers.

Even where CCS is fitted, many owners will still find overnight AC charging cheaper and more convenient for routine use. Rapid charging is most useful on longer journeys, when you want to add electric range quickly before entering a city, low-emission area or the next part of a mixed petrol-electric trip.

Range and Efficiency

The GLE 350e’s official electric range varies by source, body style and vehicle configuration. ADAC lists around 97 km, or about 60 miles, for the SUV, while other public data gives a wider range of roughly 52-66 miles depending on SUV or Coupé body and specification.

Real-world electric range will usually depend on speed, temperature, route, driving style, wheel and tyre choice, cabin heating or cooling use, and how much of the journey is at motorway speed. As a large SUV plug-in hybrid, the GLE 350e is likely to be at its best electrically on urban, suburban and moderate-speed routes rather than long high-speed motorway sections.

To get the best out of the vehicle, charge it regularly. A plug-in hybrid that starts each day with a full battery can complete many short trips without using much petrol. A plug-in hybrid that is not charged frequently carries the weight and complexity of the battery system without gaining the same efficiency advantage.

Charging at Home

Home charging is usually the simplest and most cost-effective way to run a GLE 350e as a plug-in hybrid. A dedicated 7.4 kW home wallbox, installed by a qualified professional, is well matched to the older GLE 350e’s AC charging capability. It can typically refill the battery overnight or between regular daily trips.

For a home wallbox with a socketed outlet, you will need a Type 2 to Type 2 charging cable. For the GLE 350e’s 7.4 kW AC limit, a 32 amp single-phase Type 2 cable is normally the appropriate minimum choice. If you regularly use public AC posts, keeping a cable in the boot is also sensible.

A 3-pin charging lead can be useful in some situations, but it should be treated with care. A 3-pin charger is generally best suited as a backup or occasional charging solution, but can be used regularly if a qualified electrician has confirmed the socket and electrical installation are suitable for sustained EV charging. Avoid using damaged sockets, extension leads or unknown outdoor supplies.

If you have a smart tariff, scheduled charging can help reduce running costs by charging during cheaper off-peak periods. This is particularly useful for a plug-in hybrid with a relatively large battery because a regular charging routine has a noticeable impact on petrol use.

Public Charging

For public AC charging in the UK and Europe, the relevant cable is Type 2. Many workplace, hotel, supermarket and town-centre chargers require you to bring your own cable, so a Type 2 cable is the main accessory for day-to-day public charging.

When using a public AC charger rated above 7.4 kW, remember that the older GLE 350e will not necessarily use the full output of the post. The vehicle’s onboard charger controls the AC charging limit. A 22 kW post can still be used, but it should not be expected to charge the car at 22 kW.

If your car has the CCS Combo 2 inlet, you may also be able to use compatible DC rapid chargers. These usually have tethered cables attached to the charger, so you do not need to bring a separate DC cable. Check the charging flap, the vehicle handbook or the VIN/specification record to confirm whether your specific GLE 350e has the optional DC charging function.

Vehicle-Specific Features

The most important vehicle-specific point is model identification. The name GLE 350e refers to the petrol plug-in hybrid discussed here. It should not be confused with the GLE 350 de, which is a diesel plug-in hybrid, or the GLE 400 e, which is a newer petrol plug-in hybrid. Those vehicles can have different charging specifications.

The second point is charge-port identification. A Type 2 port is expected for AC charging. CCS rapid charging may be available only where the vehicle has the lower DC pins below the Type 2 section. This is worth checking before relying on rapid charging during a journey.

The third point is cable rating. Many GLE 350e owners do not need a cable rated beyond 32 amp single-phase for the car itself, because the older GLE 350e’s quoted AC limit is 7.4 kW. Higher-rated cables can still be used where compatible, but they do not override the car’s onboard charging limit.

Charging Tips

Check the exact model: Confirm whether your car is a GLE 350e, GLE 350 de or GLE 400 e before using charging-speed information.
Inspect the charge port: If you want to use rapid charging, check for the two lower CCS DC pins.
Choose the right Type 2 cable: A 32 amp single-phase Type 2 cable is sufficient for the older GLE 350e’s quoted 7.4 kW AC charging limit.
Charge little and often: Plugging in regularly helps maximise electric miles and reduces petrol use on local journeys.
Use rapid charging selectively: If fitted, CCS rapid charging is useful on longer trips, but AC charging is usually better for routine home and destination charging.
Do not assume newer specifications apply: Current GLE plug-in hybrids may differ from the older GLE 350e.

Frequently Asked Questions

Is the Mercedes GLE 350e a fully electric car?

No. The Mercedes GLE 350e is a petrol plug-in hybrid. It can drive on electric power when the battery has charge, but it also has a petrol engine.

What charging cable does the Mercedes GLE 350e use?

For UK and European AC charging, the GLE 350e uses a Type 2 connection. A Type 2 to Type 2 cable is the usual choice for home wallboxes with sockets and public AC charging posts.

Do I need a 7 kW, 11 kW or 22 kW cable?

For the 2020-2023 European GLE 350e, public data points to AC charging up to 7.4 kW on single phase. A 32 amp single-phase Type 2 cable is therefore sufficient for the vehicle.
