Common models
| Model | Used for |
|---|---|
| Flat per-kWh | Workplace, simple public charging. |
| Time-of-use | Public AC where you want to spread load. |
| kWh + idle fee | Public DC where you need to discourage hogging. |
| Subscription + per-kWh | eMSP-style retail offers. |
Tariffs apply at the moment a session starts. Mid-session tariff changes don’t retroactively reprice a running session.
