At the station — first 2 minutes
Check the operator app (Statiq, Tata Power EZ Charge, ChargeZone, etc.) — sometimes the gun is fine but payment or RFID failed.
Look at your backup list on the trip page. Tap the next option on the map; EV Grids re-checks whether you can reach it from your current SOC.
If live status shows busy (0 free), do not wait more than 10–15 minutes on a single-gun site if a backup is within 5–10 km.
