1,000 km at highway Wh/km is more energy than most Indian EV packs hold twice over. You will charge more than twice. Overnight mode on EV Grids biases ranking toward lodging-adjacent sites when you will sleep on the road; it does not book a room or guarantee a charger in the parking lot.
Use a corridor page that is actually that long (for example Delhi → Mumbai or Hyderabad → Goa plus a second day), or split the plan into two origin–destination pairs so each day has its own backups. Cached long routes may be chunked in the API so discovery stays fast — that is an implementation detail, not a promise that every chunk has dense DC.
