Mercedes EQB charging station: which one should you choose?

The Mercedes EQB holds a distinctive place in the star's electric range: it's the family SUV par excellence, available with up to seven seats, built for the daily commute as much as for fully loaded weekend getaways. Where other models bet on sportiness or showy luxury, the EQB plays the card of reassuring versatility, with the interior space and the finish you'd expect from a German premium vehicle. And with a homologated range of 532 km WLTP, it has the shoulders to become a household's only car.

But once the SUV is in the driveway, one question invariably comes up: how do you charge it at home, and above all with which charging station? This is precisely where the EQB stands apart from many competitors, because its onboard charger accepts a higher power than average. The trick is knowing how to make the most of it — and avoiding overspending on equipment the car will never use. This guide walks through the EQB's real specifications to help you choose the charging station that's genuinely suited to your home.

Mercedes EQB: what you need to know about charging

Before comparing solutions, let's lay out the figures that really matter. They, and they alone, determine which equipment is relevant for your garage.

• Battery capacity: 70.50 kWh, a comfortable energy reserve that explains the family SUV's generous range.
• WLTP range: 532 km, more than enough to cover the week's journeys and to consider long trips with peace of mind.
• Alternating current (AC) charging power: 11 kW. This is the maximum power the car's onboard charger accepts on a home charging station — an advantage over many competitors capped at 7.4 kW.
• Direct current (DC) fast-charging power: up to 100 kW on public fast chargers.
• Plug: the European Type 2 standard for AC charging at home, and the Combo CCS connector for DC fast charging.
• Performance: 190 hp, 0 to 100 km/h in 8.90 s and a top speed of 160 km/h.

The central figure for your choice of charging station is the 11 kW in AC. To interpret it properly, a detour through the difference between kW and kWh is in order: kW expresses a power (the speed at which energy flows into the battery), kWh a quantity of stored energy. With its 70.50 kWh to fill, the EQB can draw up to 11 kW on a home charging station — provided your installation is three-phase.

AC and DC charging: understanding the difference

Every electric car charges in two distinct ways, and the EQB is no exception. This distinction is the key to not choosing the wrong equipment.

Alternating current (AC) charging is the kind used at home and at the majority of neighbourhood charging points. The grid's alternating current is converted into direct current by the car's onboard charger — and it's this charger that sets the ceiling. On the EQB, it accepts up to 11 kW, provided a three-phase supply. This is the mode that concerns you for charging at home: regular, quiet, perfectly suited to overnight charging.

Direct current (DC) charging, on the other hand, bypasses the onboard charger: the fast charger delivers direct current straight to the battery, which allows far higher power levels — up to 100 kW for the EQB. It's reserved for public fast chargers, on motorways or at stations, for long trips. You don't install it at home: this equipment costs tens of thousands of euros and makes no sense for residential use.

In short: at home, it's AC up to 11 kW; on the road, it's DC to recover a lot of energy in a short time. Two complementary logics.

How long does it take to charge the Mercedes EQB at home?

Good news: since the EQB's battery capacity is known (70.50 kWh), charging times can be estimated precisely. The principle is simple: you divide the energy to be charged by the power actually delivered. But this power is capped by the weakest link in the chain — here, the car's onboard charger, limited to 11 kW.

The direct consequence: as long as the charging station stays at or below 11 kW, it sets the pace; beyond that, the car becomes the limiting factor. A 22 kW charging station will therefore charge the EQB at exactly the same speed as an 11 kW one, because the onboard charger caps at 11 kW. Here are the ballpark figures for a full charge, from 0 to 100%:

Charging solution	Usable power for the EQB	Estimated charging time
Standard socket	2.3 kW	around 31 h
Reinforced socket	3.7 kW	around 19 h
Wallbox 7.4 kW (single-phase)	7.4 kW	around 10 h
Wallbox 11 kW (three-phase)	11 kW (car's ceiling)	around 6 h 30
Wallbox 22 kW (three-phase)	11 kW (capped by the car)	around 6 h 30

The table reads clearly: a 7.4 kW wallbox charges the EQB overnight, and an 11 kW three-phase charging station even drops to around 6 h 30. Stepping up to 22 kW, on the other hand, brings nothing more, since the car caps at 11 kW. To dig deeper into these ballpark figures, see our guide to electric car charging times.

Which charging station should you choose for the Mercedes EQB?

Here the choice depends on your electrical installation, since the EQB accepts 11 kW in AC. Two scenarios present themselves, and both lead to a relevant solution.

If your home is single-phase — the most common case in individual housing — a 7.4 kW wallbox is the right choice. It charges the EQB overnight, in around ten hours, which easily covers the week's journeys given the 532 km of range. It's the simplest solution to install and the most economical, and it amply suffices for the vast majority of daily uses.

If your installation is three-phase, you can fully exploit the car's 11 kW charger with an 11 kW wallbox. This is the maximum charge possible at home for the EQB: the battery then fills in around 6 h 30, a welcome advantage if you drive a lot or if you want to take advantage of shorter off-peak windows. There's no point, however, in aiming for a 22 kW wallbox: since the car caps AC charging at 11 kW, the excess power would remain entirely unused and you'd be paying for equipment for nothing.

The 7.4 vs 22 kW debate therefore has a nuanced answer for this model: 7.4 kW in single-phase, 11 kW in three-phase, never 22 kW. The deciding point is to know your type of supply — which is why we systematically check the power rating of your meter beforehand. To frame your decision according to your home and your budget, our method for choosing your charging station guides you step by step. And rather than a simple reinforced socket versus a real charging station, a wallbox brings the speed, safety and smart control that a socket could never offer on a vehicle of this size.

Fast charging for long trips

It's on the motorway that fast charging comes into play. The EQB accepts up to 100 kW in direct current, which lets you recover a substantial share of range in the time of a break. Mercedes announces a charge in 31 minutes on a compatible fast charger — the equivalent of a lunch or a coffee break to set off again with a good energy reserve.

With its 532 km of WLTP range, the EQB requires few stops on a long journey: one or two fast-charging breaks are generally enough to cover a long distance, timing the stops around the natural needs of the driver and the family. Good practice is to aim for the 20–80% battery window, where fast charging is most efficient, rather than chasing 100% at every charger. Our guide to motorway charging on long trips details how to plan these stages with peace of mind.

How much does charging at home cost?

Charging at home remains by far the most economical option for the EQB — it's one of the electric vehicle's great everyday advantages. The calculation is simple: you multiply the energy charged (in kWh) by the price per kWh of your electricity contract. For a full charge, you therefore reason in terms of the battery capacity, i.e. 70.50 kWh.

We won't give a fixed electricity rate here, because it depends on your supplier, your tariff option and the way prices evolve. The real optimisation variable, on the other hand, is universal: off-peak hours. By scheduling the EQB's charge at night, during the reduced-rate windows, you noticeably lower the cost of each energy top-up. A controllable charging station triggers the charge automatically during these favourable time slots, which fits perfectly with the 6 h 30 of three-phase charging.

To estimate your budget precisely, rely on our feature dedicated to the cost of charging at home. And to go further in optimisation, the logic of off-peak hours and vehicle-to-home opens up interesting avenues for the years ahead.

Frequently asked questions

Which charging station should you install for a Mercedes EQB?

It all depends on your installation. In single-phase, a 7.4 kW wallbox charges the EQB overnight and covers the vast majority of needs. In three-phase, an 11 kW wallbox exploits the full potential of the onboard charger and brings the charging time down to around 6 h 30. There's no point, however, in aiming for a 22 kW charging station: the car caps at 11 kW in AC.

Does the Mercedes EQB charge faster on a 22 kW charging station?

No. The EQB's onboard charger limits AC charging to 11 kW. Plugged into a 22 kW charging station, the SUV will keep charging at 11 kW maximum. The charging station's extra power would remain entirely unused — an 11 kW charging station is enough to reach the fastest charge possible at home.

How long does it take to charge the Mercedes EQB at home?

Allow around 6 h 30 for a full charge of the 70.50 kWh battery on an 11 kW three-phase wallbox, and around 10 h on a 7.4 kW single-phase wallbox. A 3.7 kW reinforced socket would take around 19 h, and a 2.3 kW standard socket close to 31 h — hence the value of a real charging station for daily use.

Which plug does the Mercedes EQB use?

The EQB charges in Type 2 for alternating current at home, and in Combo CCS for direct current fast charging at public chargers. It's the current European standard, compatible with the vast majority of charging stations.

Do you need to call on an IRVE-certified installer?

Yes. For a charging station above 3.7 kW, regulations require installation by an IRVE-certified professional, a condition also required to benefit from grants. Beyond the obligation, it guarantees the safety of the installation. Our guide to choosing an IRVE installer details the points to check.

How much does it cost to install a charging station for a Mercedes EQB?

The price depends on several factors: type of supply (single-phase or three-phase), distance between the electrical panel and the charging station's location, and the power chosen. Rather than putting forward an approximate figure, we cost your project free of charge and precisely with a quote within 48 hours after a complete brief, across France, with no commitment. That way you know the exact cost before any decision.

Can I install my EQB's wallbox myself?

No, self-installation is strongly discouraged and even prohibited by regulations for any charging station above 3.7 kW: the installation must be carried out by an IRVE-qualified professional. Beyond the obligation, a DIY installation exposes you to serious electrical risks and means losing the benefit of the grants. Our certified technicians (P1, P2, P3 designations) guarantee an installation compliant with the NF C 15-100 standard, with a 30 mA Type B residual current circuit breaker.

Are there any grants to install a charging station for my Mercedes EQB?

In summary

The Mercedes EQB is a versatile family electric SUV: 70.50 kWh of battery, 532 km of WLTP range, 11 kW of alternating current charging and up to 100 kW of fast charging, for 31 minutes on long trips. For charging at home, the rule adapts to your installation: a 7.4 kW wallbox in single-phase charges the SUV overnight, while an 11 kW wallbox in three-phase exploits the car's full potential in around 6 h 30. The 22 kW remains superfluous, as the EQB caps at 11 kW. By complementing everyday AC with DC fast charging on the road, you get the best out of the vehicle.
