Fast and flexible EV charging for any location
eRail is a modular, mobile charging system that lets you deploy EV charging in hours instead of weeks or months and without any large upfront investment.

Charging that adapts to your needs
Each eRail unit brings 8 AC charging points together in one integrated system, with the possibility to add high-power DC charging. Use as a single unit or link several into a larger setup. Ideal for tourism destinations, workplaces, industrial areas, logistics hubs, rental properties, commercial sites, and more.
With eRail you can start small and scale quickly as demand grows. And because eRail is surface-mounted, you can move it easily if you relocate or usage shifts.
More revenue, lower cost
Forget large upfront investments and long payback times. eRail can be rented with a flexible 6-60 month agreement starting from 595 €/month (75€ per charging point).
When combined with eTank (coming in 2026), the system can also participate in energy trading and reserve markets, generating additional revenue when cars aren’t charging. No downside for users, just extra income for the operator.

Install in hours, not months
Traditional charging requires planning, digging, permits, and construction. eRail requires a single 2 × 63A supply. Place the unit, connect one cable, and it’s ready to use.

- Charge up to 12 vehicles from one system
- Portable, surface-installed
- Single grid connection with dynamic load balancing
- Supports AC charging with optional integrated DC fast charging
- OCPP-compatible and backend-agnostic
