EV Road Trips Without Range Anxiety
Éclair is the smart EV trip planner that tells you exactly how much battery you'll have at every point along your route — accounting for elevation, weather, traffic, and your personal driving style.
Why EV Drivers Need a Dedicated Trip Planner
Standard navigation apps treat electric vehicles like petrol cars. They'll tell you the fastest route, but they won't tell you if you'll arrive with 3% battery or need an emergency charging stop at a broken charger in the middle of nowhere. Range anxiety is real — and it's the number one barrier to EV adoption for long-distance travel.
Éclair solves this by building an energy model around your specific vehicle. It knows that a Renault Zoe handles alpine passes differently from a Tesla Model 3, that headwinds on the A10 cost more than tailwinds save, and that 5°C in January means your heat pump is working overtime. Every route comes with a state-of-charge curve that updates in real time as you drive.
What Makes Éclair Different
Real Energy Modeling
Not just range estimates — Éclair simulates your entire trip using elevation data, weather forecasts, traffic conditions, and your vehicle's actual consumption curve learned from past trips.
Automatic Charging Stops
Éclair places charging stops where they make sense — optimizing for minimum total trip time, not just the next available charger. It searches IRVE, OpenChargeMap, and Qualicharge networks across France.
100+ EV Models
Accurate battery specs, consumption curves, and charging profiles for over 100 electric vehicles. From the Dacia Spring to the Mercedes EQS.
Eco-Driving Coach
Real-time recommendations during navigation help you drive more efficiently. Slow down before that hill. Coast into the roundabout. Your personal energy coach learns your habits over time.
Departure Optimizer
Choose the best time to leave based on Bison Futé traffic forecasts, historical congestion patterns, and even the carbon intensity of the French electrical grid.
Community Road Alerts
Report and receive real-time hazard warnings from fellow EV drivers. Official Bison Futé road events are included automatically.
Built for France and Europe
Éclair integrates with French public data sources that generic EV apps ignore: the national IRVE charger registry, Bison Futé traffic forecasts, data.gouv.fr fuel prices (for gas savings calculations), and FranceConnect authentication for vehicle history via HistoVec. Whether you're commuting through Paris or driving to the Côte d'Azur, Éclair knows the local infrastructure.
Privacy by Design
Ghost mode hides you from other drivers. Privacy zones suppress location sharing near home or work. All community data is anonymized via grid hashing. GDPR data export and deletion are built in — not an afterthought. No tracking, no ads, no selling your location data.
