About EV Public Charging & Idle Fee Calculator

Public charging cost breakdown

Total = (kWh × $/kWh) + session fee + (idle minutes × idle $/min). Effective $/kWh helps compare networks with different fee structures.

Avoiding idle fees

Move your vehicle within the grace period shown in the app—often 5–15 minutes after charging completes. Idle fees encourage turnover at busy stations.

Frequently asked questions

Q: Are session fees common? A: Many DC networks charge $0–$2 per session plus per-kWh. Q: What if kWh is zero? A: You may still pay a session or idle fee.
