A first highway EV trip fails for boring reasons: you left at 62% SOC, you trusted ARAI kilometres, you queued at a single 50 kW gun on a Saturday, or you had no operator app logged in. The checklist above is the minimum. Add a printed or PDF itinerary, a 10-metre cable if you might use destination AC, and a co-driver who knows which backup you picked.
Calibrate Wh/km on a familiar 80–120 km dual-carriageway before the big day. If that loop used 18 kWh, you already know more than a brochure. Type that efficiency into EV Grids. Then plan a corridor you have driven on petrol — Hyderabad → Bangalore or Delhi → Jaipur — not an unknown ghat.
Pack like a petrol trip plus charging friction: RFID or UPI that works offline, a phone mount, and the expectation that one stop will be slower than the card suggested. If that prospect ruins the holiday, you are not ready yet — do a 200 km day first.
