Equip your parking without touching your EDF subscription.
The challenge of IRVE (EV charging infrastructure) deployment in a company isn't the cost of the charging stations — it's the electrical capacity. With Spark Pilot and Sparklin's native load balancing, you deploy 15, 50 or 140 charging stations without renegotiating your EDF contract and without grid-reinforcement works.
Four obstacles no one had anticipated.
The Enedis obstacle. Adding charging stations increases the site's consumption. If it exceeds the subscribed capacity, you have to renegotiate the contract and wait for Enedis to step in. Observed lead time: 6 to 12 months in dense areas. For an SME that just wanted to install a few charging stations, it's a rude awakening.
The budget obstacle. A 22 kW charging station costs between €1,500 and €4,000. Multiplied by ten locations, the bill exceeds €30,000 before you even factor in the works, the cabling and the dedicated electrical panel.
The operational obstacle. Who manages the charging stations? Who decides who charges and when? How do you prevent the same employees from monopolising the outlets? How do you track consumption in order to reimburse or re-invoice it?
The invisible technical obstacle. Without smart management, ten 7 kW charging stations active simultaneously can exceed the EDF subscription ceiling — with penalties potentially reaching several thousand euros per month.
What Sparklin changes, point by point.
A direct, technical and documented answer to each of the four obstacles.
Load balancing removes the Enedis obstacle
Spark Pilot monitors the site's total electricity consumption in real time and distributes the available power across all active charging stations. If your subscription allows 100 kW and the building is consuming 70, Spark Pilot distributes the remaining 30 kW among the vehicles being charged — every second, automatically. The result: zero overruns, zero EDF penalties, zero Enedis intervention.
CAPEX divided by five thanks to slow charging
An employee who arrives at 9am and leaves at 6pm has nine hours of charging. At 3.7 kW, that's 33 kWh recovered — enough to fully recharge the vast majority of electric vehicles on the market. A Spark Plus comes to less than €300, compared with €1,500 to €4,000 for a 22 kW charging station. For ten locations, the CAPEX gap is in the order of €25,000.
Frictionless access management
Create communities, define priority access, reserve charging stations for a group of users. Spark Pilot adapts to the company's organisation. The site manager adds or removes access in a few seconds from the web interface. Every session is logged with the employee's name, the vehicle, the duration and the energy consumed.
Total visibility for the fleet manager
Real-time dashboard, exportable monthly reports, centralised multi-site view. The data feeds into RSE (corporate social responsibility) reporting, tax declarations and total-cost-of-ownership analyses. For multi-site companies, Spark Pilot centralises the supervision of every car park — headquarters, branches, home outlets — from a single interface.
Industrial SME · 45 employees · 15 electric vehicles
| Indicator | Sparklin solution | Conventional fast chargers |
|---|---|---|
| Hardware cost (15 charging points) | 4 200 € | 14 000 € |
| Works and installation | 22 500 € | 37 000 € |
| EDF subscription renegotiation | None | ~ €2,000 + 6 to 12 months |
| Spark Pilot subscription | ~ €75 / month | ~ €200 / month |
| Risk of overrun | None (load balancing) | High without management |
| Commissioning lead time | 3 to 6 weeks | 6 to 12 months |
| TOTAL CAPEX | 26 700 € | 51 000 € |
For an SME, the CAPEX saving represents more than €30,000 that can be reinvested in its core business. And cutting the commissioning lead time from 6–12 months to 3–6 weeks means, in concrete terms, that your employees charge this summer, not next year. Assumptions: Spark Plus at €300/unit, installation €200/charging station; fast charging stations €2,000/unit, installation €500/charging station.
What the law says, and what it changes for your budget.
Tertiary decree
Tertiary buildings of more than 1,000 m² have obligations to reduce energy consumption. Installing charging stations with load balancing contributes to controlling the site's electricity consumption and can be valued in OPERAT reporting thanks to consumption exports.
LOM Act
The mobility orientation act (loi LOM) sets growing obligations to equip company car parks with charging stations during renovation or construction works. Planning ahead avoids forced compliance measures, which are often more costly when carried out under pressure.
Tax advantages
Installation and operating costs are deductible under favourable conditions. The reimbursement of charging costs to employees, documented by Spark Pilot data, is exempt from social-security contributions subject to justified actual-expense conditions.
