Charging Speed
Both chargers deliver identical charging speed at 11.5kW (48A). In practice, this means:
| Vehicle Battery | Enel X Time | Siemens Time |
|---|---|---|
| 60 kWh (e.g., Tesla Model 3) | 5.2 hrs | 5.2 hrs |
| 75 kWh (e.g., Tesla Model Y) | 6.5 hrs | 6.5 hrs |
| 100 kWh (e.g., Tesla Model S) | 8.7 hrs | 8.7 hrs |
Since both chargers deliver the same power, charging time is identical. The decision comes down to features and price.
Important: Most EVs have an onboard charger that caps AC charging speed (typically 11-11.5 kW). If your car maxes out at 11 kW, both chargers will charge at the same rate regardless.
