EV charging maintenance · France & Belgium · since 2019
Your chargers, available.
Our team, on site.
Installation, maintenance and repair of your EV chargers. From diagnosis to report, one contact follows your intervention across France and Belgium.
Four disciplines, one goal: your chargers available.
You run a fleet of charging stations. You need them to work. We install, we maintain, we repair.
Preventive & corrective maintenance
Preventive, corrective, HV/LV. Remote diagnostics first, then on-site intervention with the right parts on board.

Across France, and Belgium.
Technical teams spread across the entire territory: Île-de-France, Hauts-de-France, Auvergne-Rhône-Alpes, PACA, Occitanie, Nouvelle-Aquitaine and beyond. We also operate in Belgium.
See our coverageYour questions. Our direct answers.
We have a large rollout to launch, can you handle it?
200 chargers over 12 months, is that feasible?
Yes. We manage portfolios of 50 to 500+ charging points. Scheduling, installer coordination, budget, reporting: everything is driven by a dedicated project manager. You get a progress report, not surprises.
And if it spans 15 different sites?
That is exactly where we add the most value. One single dashboard, one person to call, consistent standards across all your sites.
Our existing fleet has compliance issues
We have a fleet installed by someone else, can you take it over?
Yes. We audit it, list what is blocking, and prioritise the corrections. You walk away with a clear plan and up-to-date documentation for the inspection body.
Do you also handle exchanges with the inspection body?
Yes. Technical documentation, responses to observations, grid operator coordination: we take care of it so you do not have to juggle between contacts.
Our chargers are often unavailable
How quickly do you intervene?
Response times are defined in your maintenance contract. Before any dispatch, we run a remote diagnostic. The goal: fix the fault on the first visit and, if a part is missing, return without billing an additional call-out.
We have a multi-brand, multi-installer fleet. Is that a problem?
No, that is our speciality. We audit it, identify the weak points, and stabilise it. Many of our clients came to us for exactly that.
We have vandalism problems at our sites
When should a site be secured?
As soon as the first incident occurs. Or better: before. Isolated site, recurring cable theft, low foot traffic at night? We run the diagnosis and act fast.
We already have a security provider, is that compatible?
Yes. We integrate into your existing setup (CCTV, alarms, security patrols) so that chargers are treated like your other critical assets.
Our users call too much and we cannot keep up
Can you answer on our behalf?
Yes. We operate as a white label, with your scripts, your tone, your processes. Your users notice no difference.
And to reduce call volume?
We analyse why people call. Often it is a recurring technical issue. We fix it at the source, and the calls drop.
Ready to entrust your chargers to a certified EV charging maintainer?
Describe your situation. A technician who knows the field will call you back within 48 hours. Not a salesperson.
