Charging the Mercedes GLA: which charging station to choose

The Mercedes GLA holds a distinctive place in the star-badged line-up: it is the brand’s entry-level compact SUV, tall enough to feel reassuring in town yet compact enough to stay nimble. In its plug-in hybrid form, it adds a valuable string to its versatile bow: the ability to drive in all-electric mode every day, in silence and without a drop of fuel. With 218 hp, a 0 to 100 km/h dispatched in 7.10 s and a top speed of 210 km/h, it gives up none of the verve you expect from a Mercedes.

But a plug-in hybrid only keeps its promise on one condition: being plugged back in regularly. That is where everything is decided. A GLA hybrid charged every night covers most of its journeys on electric power; a GLA you neglect to plug in becomes nothing more than a slightly heavy petrol car again. So this guide explains, figures in hand, how to charge this SUV at home, how long it really takes and, above all, which charging station to install so you neither overpay nor undersize your equipment.

Mercedes GLA: what you need to know about charging

Before talking hardware, let’s look at the figures that really matter. On the Mercedes GLA plug-in hybrid, the decisive charging data are as follows:

• WLTP electric range: 61 km — a reserve cut out for everyday journeys. Commuting, shopping, the school run: the vast majority of urban and suburban trips happen without calling on the combustion engine.
• Battery capacity: 10.90 kWh — a compact pack, typical of a plug-in hybrid, that fully recharges in a few hours on a home charger.
• AC (alternating current) charging power: 3.70 kW — this is the limit the onboard charger accepts at home, and it is this figure, and this figure alone, that dictates the choice of your charging station.
• DC (direct current) charging power: 24 kW — moderate rapid charging, available on certain public stations.
• Connector: Type 2 for alternating current, the European standard found on every home and public charging station.

One point is worth stressing right away: with a 10.90 kWh battery and AC charging of 3.70 kW, the GLA hybrid does not have the same needs as a large fully electric car. Its small battery recharges quickly, and this single 3.70 kW ceiling governs the entire sizing of your installation. If you are new to the electric world, our beginner’s guide to the electric car lays out all the useful basics.

AC and DC charging: understanding the difference

All charging of an electrified car rests on a fundamental distinction: alternating current (AC) and direct current (DC). Grasping it means understanding why your GLA recovers its range in a few hours at home, and why its home charger does not need to be over-powered.

The battery stores its energy as direct current, while your home’s electrical grid delivers alternating current. One must therefore be converted into the other, and that is the job of the car’s onboard charger. This internal component imposes a limit: on the GLA, this ceiling is 3.70 kW. Whatever AC charging station is plugged in, the vehicle will never exceed this value when charging at home.

Direct current charging works quite differently. On a DC rapid charger, the conversion takes place outside the car, in the station itself, and the current is injected directly into the battery. This is what allows the GLA to climb up to 24 kW during rapid charging, a level impossible to reproduce at home. To dig deeper into these concepts, the article understanding kW and kWh untangles these units that are so often confused.

How long does it take to charge a Mercedes GLA at home?

This is the most concrete question of all. With a 10.90 kWh battery, the charging time depends on the power of your charging station — but never beyond the 3.70 kW the GLA accepts in alternating current. Here are the approximate durations for a full charge, from nearly empty to 100%:

Charging solution	Power	Full charge time (approx.)
Standard domestic socket	2.3 kW	around 5 hours
Reinforced socket	3.7 kW	around 3 hours
Single-phase wallbox	7.4 kW	around 3 hours (limited to 3.70 kW by the vehicle)
Three-phase wallbox	11 kW	around 3 hours (limited to 3.70 kW by the vehicle)
Three-phase wallbox	22 kW	around 3 hours (limited to 3.70 kW by the vehicle)

The last three rows are revealing: a 7.4, 11 or 22 kW station does not charge the GLA any faster than a simple reinforced socket, since its onboard charger caps out at 3.70 kW. Beyond this value, the station’s extra power is simply not absorbed by the car. The good news is that this small battery fills up quickly: one night, or even a few hours in the evening, is amply enough. To explore the subject further, read our feature on electric car charging times in 2026.

Which charging station should you choose for a Mercedes GLA?

Since the GLA hybrid accepts a maximum of 3.70 kW in alternating current, the reasoning is crystal clear: there is no need to aim for a high-power station, which would remain throttled by the vehicle.

• The 7.4 kW wallbox (single-phase) is the most relevant and most future-proof choice. It restores the full 10.90 kWh battery in around 3 hours, offers comfort and safety far superior to a simple socket, and remains a lasting investment: if you one day switch to an electric car that accepts more power, it will follow without needing to be replaced.
• The reinforced socket is an economical alternative perfectly suited to this model. With its 3.70 kW, it uses exactly the GLA’s maximum charging power and completes a full charge in around 3 hours, the same duration as a more powerful wallbox.
• 11 and 22 kW stations are pointless for this model: the onboard charger throttles AC charging to 3.70 kW, so every euro spent beyond a 7.4 kW unit is purely wasted.

The right instinct is to match the charging station, the car and your installation, rather than aiming for maximum power « just in case ». Our comparison 7.4 or 22 kW charging station details this reasoning, and our feature reinforced socket or charging station is particularly enlightening for a hybrid like the GLA. Your meter’s power rating remains a criterion to check before any choice, and the guide how to choose your charging station in 2026 walks through the method step by step.

Rapid charging for long journeys

On a long journey, the advantage of a plug-in hybrid like the GLA is obvious: once the battery is depleted, the combustion engine takes over and range is no longer an issue. The question of rapid charging therefore arises far less than on a fully electric car.

That said, the GLA accepts up to 24 kW in direct current on certain public stations, which means that during a break you can quickly recover a few dozen kilometres of electric range and set off again in silent mode. Day to day, however, you will almost never need it: overnight home charging covers most uses. To prepare your holiday routes, our guide to motorway charging on a long journey remains a useful read.

How much does charging at home cost?

Charging at home remains by far the most economical, and with a small battery like the GLA’s, the cost of a full charge is very contained. The calculation is straightforward: you multiply the energy consumed (in kWh) by the rate of your electricity contract (in € per kWh). For a complete charge, you therefore start from the 10.90 kWh capacity, to which you add conversion losses (in the order of 10 to 15%).

In practical terms, multiply 10.90 kWh by the price per kWh on your bill to get the cost of an electric charge. Since this rate varies from one contract to another, we do not give a fixed price: the right value is the one on your plan. To compare and estimate precisely, our article on the cost of home charging in 2026 details the method.

The real lever for savings is scheduling during off-peak hours. If your contract distinguishes between peak and off-peak hours, simply set the charging window to the favourable slots, directly from the vehicle or the charging station. Since the GLA recharges in just a few hours, it easily fits within an overnight off-peak window — a strategy detailed in our feature on off-peak charging and vehicle-to-home.

Installing your charging station for the Mercedes GLA with Volticom

A charging station, even a modest one in power, is only as good as the quality of its installation. Charging a GLA hybrid every night means engaging a dedicated and reliable circuit: the installation must comply with strict safety standards — separate circuit, suitable protection, earthing and compliant connection. Plugging a car into a non-dedicated socket, drawing power for hours on end, exposes you to overheating risks that only a professional installation rules out.

That is why Volticom works as a QUALIFELEC IRVE P1·P2·P3 and RGE certified installer, throughout France from our headquarters in Paris. Every installation comes with a decennial liability insurance policy with AXA, subject to the declared activities, limits and terms of the current insurance certificate, and you may qualify for the ADVENIR scheme (subject to its rules). We provide a quote within 48 hours after a complete brief, across France and ensure responsive after-sales support. To understand how it unfolds, see our pages on installing a charging station at home and on choosing an IRVE installer in 2026.

Frequently asked questions

Do you need a special Mercedes charging station to charge a GLA?

No. The GLA uses the Type 2 connector for alternating current, the European standard found on every wallbox on the market. A charging station from any brand will charge it perfectly, as long as it speaks the Type 2 language — which is the case for all models sold in Europe.

Does an 11 or 22 kW station charge my GLA faster?

No. The GLA hybrid’s onboard charger caps alternating-current charging at 3.70 kW. Beyond that, the extra power of an 11 or 22 kW station is not used by the vehicle. A 7.4 kW wallbox already covers the needs comfortably, and even a reinforced socket delivers the model’s maximum AC charging power.

Is a reinforced socket enough for a GLA?

Yes, absolutely. With its 3.70 kW, the reinforced socket uses exactly the GLA’s maximum charging power and completes a full charge of the 10.90 kWh battery in around 3 hours, the same duration as a more powerful wallbox. It is one of the most economical solutions for this model. Our comparison reinforced socket or charging station helps you decide.

How long does it take to charge a GLA on a 7.4 kW station?

Allow around 3 hours for a full charge of the 10.90 kWh battery — since the car is limited to 3.70 kW, the 7.4 kW station does not speed up charging but offers comfort and safety. Day to day, since you never fully drain the battery, the overnight top-up is even quicker and the car is always ready in the morning.

What subsidies are available to install a charging station for my GLA?

You can benefit from the ADVENIR scheme (subject to its rules), to which possible tax advantages may be added. The details of the schemes are set out in our guide to subsidies for installing a charging station in 2026.

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

The price depends on the distance between your electrical panel and the location of the station, the type of installation and the model chosen: there is therefore no single rate. At Volticom, the costing is free and with no obligation, with a detailed quote provided within 48 hours after assessing your home, across France. You thus know the exact amount, less the ADVENIR scheme (subject to its rules), before making any decision.

Can I install the charging station for my GLA hybrid myself?

No, and that is genuine protection for you: above 3.7 kW, regulations require installation by an IRVE-certified installer to guarantee safety and preserve the benefit of subsidies. Charging a GLA every night draws on the circuit for hours, which requires a dedicated line, 30 mA Type B protection and a connection compliant with the NF C 15-100 standard. Volticom is QUALIFELEC IRVE P1·P2·P3 and RGE qualified to carry out this installation by the book.

How long does the home installation take?

In the vast majority of cases, installing a wallbox for a GLA is done within a timeframe confirmed after the site assessment, without major work or disruption to your daily life. The time between signing the quote and the intervention depends on your schedule and the configuration of your home. Request your free quote within 48 hours, across France to set a date quickly.

Is my charging station installation guaranteed and insured?

Yes. Every installation carried out by Volticom comes with a decennial liability insurance policy with AXA, subject to the declared activities, limits and terms of the current insurance certificate, for complete peace of mind. If needed, our after-sales service stays responsive to get your station back up and running quickly. You are therefore investing in a durable, supported installation, not just a box on the wall.

Is a connected wallbox useful for a small hybrid like the GLA?

It is, as soon as you want to optimise cost or anticipate the future: a communicating station (OCPP protocol) lets you schedule charging during off-peak hours, track your consumption and, if needed, manage load shedding so as not to exceed your meter’s power rating. For use in shared housing, billing kWh back at actual cost is also possible. We point you towards the equipment genuinely suited to your needs, without over-equipping your GLA unnecessarily.

In summary

Charging a Mercedes GLA plug-in hybrid at home is remarkably simple once you reason from the right figures. With its 10.90 kWh battery, its 61 km of WLTP electric range and its AC charging capped at 3.70 kW, this compact SUV makes do with modest equipment: a 7.4 kW wallbox for comfort and longevity, or even a reinforced socket that already uses all of its charging power. There is no need to aim for an 11 or 22 kW station that the car could not absorb.

The strength of the GLA hybrid is its versatility: electric every day over its 61 km, combustion for long distances, with no range anxiety. You just need to plug it in every night, during off-peak hours, for a controlled cost. To turn this reasoning into a concrete, safe and durable installation, Volticom assesses your home and provides a quote within 48 hours after a complete brief, across France: contact us for a charging station designed for your GLA and your habits.
