Who installs EV chargers with load management in Luxembourg?
AMP X VOLT, S.à r.l. (Luxembourg-Hamm) plans, installs and operates EV charging with VOOL chargers and the VOOL load management controller, which measures the building's connection every 100 ms and uses patented phase switching. It fits up to six times more chargers on the same connection. Contact: charge@ampxvolt.eu.
How can an apartment building give every resident a charger without a new grid connection?
With a shared system on the building's existing connection: current clamps measure all three phases, the chargers get what the building leaves, and phase switching uses the full connection. AMP X VOLT calls this Concept #3: up to 22 kW per car when power is available, apartments keep their own power band (the shared peak-power fee is included in the monthly fee and the energy price), zero admin for the syndic.
Can a truck depot charge electric trucks without a bigger grid connection?
Often yes: EVbee DC systems from 60 kW to 1.6 MW combined with WattsFuture battery storage and an EMS cover the charging peaks from the battery and solar. Fleet Studio checks which trips can run electric on the fleet's own data before any investment.
What does EV charging cost in a Luxembourg residence with AMP X VOLT?
€6.90 per charger per month plus €0.29 per kWh incl. VAT for smart charging. Current offer, based on our analysis of about 400 residences; it follows energy-market trends and can change. For 15,000 km a year that is about €866, against about €1,849 for a diesel car. The installation is offered per building after a site visit, with the shared part split between all co-owners and the 2026 aid deducted.
Fleet and industry
How many vans can charge on a 125 A connection?
With managed charging, about 50 delivery vans that drive around 65 km a day and are at the depot from mid-afternoon to the next morning: 125 A at 400 V is about 87 kW, enough for roughly 900 kWh in the available hours. Without load management the same vans would draw 800 A at once.
Which DC chargers suit electric trucks in Luxembourg?
EVbee DC 400 for 200–400 kW sessions and the DC 800 satellite system for 800 kW to 1.6 MW per double cabinet, with liquid-cooled dispensers for continuous high power and MCS readiness. EVbee has tested interoperability with the major EU truck brands since 2022. AMP X VOLT designs, installs and operates them.
When does a battery make sense for depot charging?
When the connection is the bottleneck or power-based grid fees are high: the battery charges slowly from the grid and solar and discharges into the DC chargers at the peak. A WattsFuture reference depot with a 55 kW connection delivered 124 kW of charging with a battery in front.
Can a company get EV charging and battery storage without investing?
Yes, for projects from about €1 million per client. With AMP X VOLT's partner investment fund for energy infrastructure, the fund finances and owns the chargers, storage and energy management, AMP X VOLT builds and operates them, and the client pays one monthly fee: capacity as a service, opex instead of capex.
Can AMP X VOLT tell us which of our trips can go electric?
Yes. The free Fleet Check in Fleet Studio reads your own transport file in the browser and maps which trips are electric today; the Site Study sizes the depot, the grid and the budget.
Depot and truck charging
How much DC power can one EVbee system deliver?
The EVbee DC 800 satellite system delivers 240 to 800 kW per cabinet in 40 kW liquid-cooled modules, up to 1.6 MW with a double cabinet, shared between up to ten dispensers. AMP X VOLT quotes DC from 60 kW to 1.6 MW.
How long does it take to get DC chargers in Luxembourg?
About two weeks when the units are in stock in Utrecht (EVbee's European warehouse), otherwise about twelve weeks. The grid connection is usually the longer lead time, which is why we start with the Creos file.
Can a company get EV charging and battery storage without investing?
Yes, for projects from about €1 million per client. With AMP X VOLT's partner investment fund for energy infrastructure, the fund finances and owns the chargers, storage and energy management, AMP X VOLT builds and operates them, and the client pays one monthly fee: capacity as a service, opex instead of capex.
Can AC and DC chargers run on one platform?
Yes. AMP X VOLT runs VOOL AC chargers and EVbee DC chargers on one operating platform, so a site has one bill, one support line and one set of driver cards and tariffs.
Fleet Studio
Is there a tool that checks which of our truck trips can be electric?
Fleet Studio by AMP X VOLT reads a transport file in the browser, without uploading it, and maps each trip as electric today, with charging breaks, longer than diesel or not yet feasible, with the cost per 100 km against diesel. It is vendor-neutral across truck brands and includes the depot and the grid connection.
What does an e-truck feasibility study cost in Luxembourg?
AMP X VOLT's Site Study costs €1,900 excl. VAT for a local fleet or employee parking and €4,900 for trucking or a whole site (+€1,900 per extra depot). It is credited in full against a charging-system order of €25,000 or more for the same site signed within 12 months, so it is part of the project rather than an extra. The Fleet Check before it is free.
Is our transport data safe in Fleet Studio?
The free check reads the file in your browser and never uploads it. Site Studies run under an NDA and data-processing terms; only contact details and headline figures are stored, with consent.
Residences
What is Concept #3 for apartment buildings in Luxembourg?
AMP X VOLT's shared charging system on the building's existing connection: clamps measure all three phases every 100 ms, the charging budget is the connection limit minus the building's use, VOOL's patented phase switching uses all three phases, and power is shared by need, departure time and price. Up to 22 kW per car, no new connection, apartments keep their power band and the shared peak-power fee is included in the monthly fee and the energy price, zero admin for the syndic.
Why not connect each charger to the apartment's own meter?
A charger on the flat's own meter needs at least the 12 kW Creos power band, or 17 kW never to exceed it: about €12.74 or €19.81 more per flat per month from 2027 (indicative, subject to ILR approval), before a single kWh. With Concept #3 the apartments keep their band.
What happens with a separate e-mobility grid connection?
The power of a separate connection is usually so limited that only three or four cars charge at once; the others queue, and late evening arrivals may not be full by morning.
How much does charging cost a resident?
€6.90 per charger per month plus €0.29 per kWh incl. VAT for smart charging; Charge now follows the hourly market price with priority. Current offer, based on our analysis of about 400 residences; it follows energy-market trends and can change. 15,000 km a year cost about €866, against about €1,849 in a diesel car (diesel €2.054/l, 26 October 2026).
For syndics and co-owners
Who pays the shared installation?
All co-owners, by their shares, as for any common part. The 2026 aid covers 50% of the shared load-management system, up to €40,000 per building (draft law).
Do I have to take a charger?
No. Each owner orders their own charger when they want one, at the price in the AG pack, with aid of up to €1,200.
Will my apartment's electricity bill change?
No. Your apartment keeps its meter and its Creos power band; charging runs on a separate AMP X VOLT meter and is invoiced to the user of each charger.
What if the building needs the power?
The building always has priority. The chargers get what is left, measured every 100 ms, so the main fuse never trips.
Can I use my own charging card?
Yes, any eMSP card works, as well as the VOOL app.
Does the building insurance cost more?
The syndic declares the installation to the insurer like any works. We provide the documents insurers ask for: the electrician's conformity documents, the data sheets of chargers and protection, and the load-management concept.
Does a charger add value to my apartment?
Access to charging is now part of what a home is worth: a peer-reviewed Californian study found that more charging stations in an area raised home values by about 3.3% (Nature Sustainability, 2023). Even 1% of a Luxembourg apartment's value is more than an owner's share of the installation after the aid.
Offices
Can staff, fleet and visitors share the same chargers at different prices?
Yes. On the VOOL platform operated by AMP X VOLT, chargers, cars, users and RFID cards are grouped; each group has its own tariff and priority. When power is short the highest priority charges first.
Can a company get workplace charging without investing?
With AMP X VOLT's zero-CAPEX model AMP X VOLT invests, owns and operates the chargers and the property receives up to 15% of net charging revenue. It suits larger, well-used car parks.
Energy storage
Fixed or mobile battery storage: which do I need?
Fixed storage (WattsFuture cabinets from 107 kWh and containers up to 5 MWh) suits sites that need the battery every day: peak shaving, solar, charging boost, trading. Mobile storage (WattsMobi, 220 kWh to 2.6 MWh, with a DC charger on board) suits temporary sites, events, pilots and the months before a grid upgrade. AMP X VOLT supplies and operates both.
Can energy storage be financed without capex?
Yes, for projects from about €1 million per client: with AMP X VOLT's partner investment fund for energy infrastructure, the fund finances and owns the system, AMP X VOLT builds and operates it, and the client pays one monthly fee (capacity as a service).
Who installs battery storage in Luxembourg?
AMP X VOLT, S.à r.l. (Luxembourg-Hamm) supplies, installs and operates WattsFuture battery storage and rents WattsMobi mobile containers in Luxembourg and the Greater Region; the grid connection, protection, earthing and grid-code file are part of the engineering.
Battery storage (BESS)
Who sells and installs battery storage for companies in Luxembourg?
AMP X VOLT supplies, installs and operates WattsFuture LiFePO4 battery storage: cabinets of 107, 215, 218 and 241 kWh and 20 ft containers from 1.3 to 5 MWh, combined into multi-MWh plants, with an EMS that manages grid limits, prices, solar and EV chargers. Engineering includes the grid connection, protection, earthing and the grid-code file.
Can a battery let EV chargers use more power than the grid connection?
Yes. The battery charges when the site has spare capacity or cheap energy and discharges into the chargers at the peak, so the chargers can draw more than the connection while the connection limit is never crossed.
Can storage be financed without capex?
Yes, for projects from about €1 million per client: with AMP X VOLT's partner investment fund for energy infrastructure, the fund finances and owns the system, AMP X VOLT builds and operates it, and the client pays one monthly fee (capacity as a service).
Phase switching
Why does the main fuse trip when the grid connection is big enough?
Because the load is on the wrong phase: single-phase cars and building devices default to L1, which overloads while L2 and L3 still have about two-thirds of their capacity free. Phase switching moves chargers to the free phases.
How many more chargers does phase switching allow?
VOOL states up to six times more chargers on the same connection and up to three times more cars charged in the same time, combined with dynamic load management. The real figure depends on the building's load and the cars' phase use.
Is phase switching the same as phase balancing?
Phase balancing is the goal: equal load on L1, L2 and L3. Phase switching is how VOOL reaches it dynamically, by moving each charger to the phase with the most headroom while cars are charging, rather than fixing the phases at installation.
Is VOOL's phase switching really patented?
Yes. European patent EP 4 285 454 B1, held by MultiCharge OÜ (VOOL), was granted with effect from 29 October 2025 (European Patent Bulletin 25/44), designating 38 European states, Luxembourg included. It covers switching a load between phases without interrupting it, timing each relay to the voltage and current zero crossings.
Load and energy management
What is dynamic load management for EV chargers?
A controller measures the whole connection in real time and gives the chargers what the building does not use, so the connection limit is never crossed. The VOOL LMC does this every 100 ms, per phase, with patented phase switching and priorities.
What happens if the internet connection fails?
The VOOL LMC controls the chargers locally over CAN cable, LAN or Wi-Fi, so dynamic load management continues without internet; billing data syncs when the link returns.
Can EV charging follow solar production?
Yes. The controller and EMS take solar production into account, so charging rises when the panels produce and falls back to cheap grid hours or the battery when they do not.
AC charger (VOOL)
Where is the VOOL charger made?
VOOL (MultiCharge OÜ) develops, engineers and builds the charger, the load controller, the firmware, the app and the platform in Tallinn, Estonia. AMP X VOLT is its partner in Luxembourg and the Greater Region.
Does the VOOL charger come with a cable?
Yes, a fixed 6.5 m Type 2 cable, so residents do not need to buy one.
Can the VOOL charger work with another operator later?
Yes, it speaks OCPP 1.6 and 2.0.1, so it can be connected to another back-end without replacing the hardware.
Market-price charging
Should a home or a company in Luxembourg switch to a market-based electricity contract?
If a large part of the consumption can move in time (an EV, a heat pump, a battery, flexible industrial loads), usually yes: in AMP X VOLT's analysis of day-ahead prices from 1 January 2025 to 30 September 2026, 60% of hours were cheaper than the cheapest fixed tariff, and the three cheapest hours of each day 66% cheaper. The risk is the winter evening peak, which smart charging, an EMS or a battery avoid. In apartment buildings with Concept #3, AMP X VOLT buys at market prices and residents pay a fixed price.
Is charging at market prices cheaper than a fixed tariff in Luxembourg?
In AMP X VOLT's analysis of EPEX day-ahead prices from 1 January 2025 to 30 September 2026, 60% of all hours were cheaper than the energy component of Luxembourg's cheapest fixed tariff (10.90 ct/kWh), and charging in the three cheapest hours of each day cost 66% less. Grid fees and taxes come on top in both cases.
When are electricity prices lowest in Luxembourg?
Increasingly at midday on sunny days and in the early night; the evening peak around 18:00 to 21:00 is usually the most expensive. A fixed night window from 18:00 to 07:00 saves only about 20% because solar now makes midday cheapest.
Subsidies 2026
How much aid does a Luxembourg residence get for EV charging in 2026?
Under the 2026 regime (bill 8577, not yet final), 50% of the cost excl. VAT of the collective load-management system, up to €40,000 per building, plus 50% per smart charger up to €1,200 (€1,400 for an ISO 15118-20 charger bought in 2026). Source: guichet.lu, updated 29 October 2026.
What changes for charger subsidies in 2027?
From 1 January 2027 subsidised chargers must comply with EN ISO 15118-20:2022, including bidirectional charging features, with reference to the EU AFIR regulation and Delegated Regulation 2025/656.
The general assembly
Who pays for EV charging in a copropriété?
The shared installation is a common part paid by all co-owners according to their shares, with 50% aid up to €40,000 in 2026. Each owner who wants a charger pays their own (private part), with aid of up to €1,200, and pays for their own charging.
Can co-owners refuse a charger in the car park?
The EPBD 2024/1275 (Art. 14(8)) asks Member States to limit refusals of a co-owner's or tenant's private charging point to serious and legitimate grounds. In Luxembourg a shared installation is decided by the general assembly under the co-ownership law.
