How to read this page
- The same tariff can produce different practical charging strategies because a wallbox shortens charging windows and supports smarter scheduling.
- A plug setup may look simpler, but long charging hours can limit when and how you refill the battery.
- Use your own off-peak rate if EV charging is tied to a time-of-use tariff.
