EV chargers (IRVE): the essentials
We equip the car parks of your public buildings with charging points (EVSE, electric-vehicle supply equipment) for service vehicles and staff, then supervise and maintain them. For publicly accessible charging points, see the public-space charging offer.
Who is it for, and for what uses?
It suits municipalities, EPCI, syndicates and landlords that charge their fleet of service vehicles: town hall, technical services, school, municipal facilities. We respond to your tenders; the specifications remain yours.
What it changes for you
The authority's vehicles charge on site, with charging points sized for their schedules. Usage tracking per point lets you report on use to your departments and elected members.
Which charging power should you choose?
For an employee or visitor car park, a 7.4 kW alternating-current (AC) charging point is usually enough: a vehicle parked for several hours charges comfortably. 11 or 22 kW are justified when vehicles park for a short time or the fleet drives a lot. Direct current (DC, fast charging) targets intensive use and requires a grid study.
The power actually used is capped by the vehicle's on-board charger: a 22 kW point does not charge faster than 11 kW a vehicle whose charger is limited to 11 kW. The times below are orders of magnitude for a vehicle consuming 16 kWh per 100 km, excluding charging losses.
| Power | Current | Time for 100 km | Typical use |
|---|---|---|---|
| 3.7 kW | Single-phase AC | about 4 h 20 | Occasional use |
| 7.4 kW | Single-phase AC | about 2 h 10 | Employee car park |
| 11 kW | Three-phase AC | about 1 h 30 | Customers, fleets |
| 22 kW | Three-phase AC | about 45 min if the vehicle accepts it | Fast turnover |
| 50 kW and above | DC | a few tens of minutes | Intensive fleets |
Which plug and which charging mode?
The Type 2 plug is the European standard for alternating current, and the CCS (Combo) connector is used for DC fast charging. In business settings, the reference is mode 3: a dedicated charging point that communicates with the vehicle to secure the charge.
The household socket (mode 1) is discouraged for safety reasons, and the reinforced socket with a control box (mode 2) remains a stop-gap. Mode 4 refers to DC fast charging.
How do you avoid raising the subscribed power?
Dynamic load management shares the available power between charging points according to the activity of the site and its other equipment. It most often avoids raising the subscribed power of your contract, and therefore the standing charge, and can shift charging to off-peak hours.
We check the power available on your site before choosing the equipment: it sets the number and power of the charging points.
What does the installation include?
We supply, install and commission one to three charging points, then handle the connection, remote monitoring and maintenance. If a point fails, we see it and we intervene.
We can also supply the electricity that feeds your charging points: you have a single contact for the equipment and for the contract.
Our solution
A turnkey charging project covers three areas:
| Criterion | With Eneffic |
|---|---|
| Study and installation | Sizing, connection and turnkey installation |
| Supervision | Remote monitoring of your charging points |
| Maintenance | Servicing and maintenance throughout the life of the installation |
Thomas's take, our expert
In a municipality, service vehicles charge at night and at weekends. I start from these schedules and the building's power to size the installation.
