Plan now uses a vehicle preset, 90% start SOC, Wh/km from preset, and cost-aware ranking on longer corridors. Adjust on the planner page if needed.
This rates how much planning the route needs, not road quality. Charger spacing comes from stations recorded in the EV Grids cache and changes as coverage grows.
Monsoon rain on NH27 and hill approaches raises landslide and washout risk. Range drops from humidity, slow convoys, and detours — enable hills & weather adjustment and plan backup stops.
Suggested planner settings: 32% reserve SOC · 38% search threshold · hills & weather on (includes monsoon adjustment Jun–Sep)
Ranked by estimated charging-stop count on ~1030 km via NH27, using each preset's configured range and consumption. This is not a recommendation based on price, safety, comfort, or overall vehicle quality.
Fewest estimated stops
Mahindra BE 9S / XEV 9S
~679 km range · Typically 1 DC stop
The ~1030 km drive is longer than one comfortable leg in a Mahindra BE 9S / XEV 9S. EV Grids estimates one DC session on NH27 when you start around 80–90% SOC.
Jump to chargers, overnight hotels, meal stops, or pick your EV model — each page links back here and opens the trip planner pre-filled for Kolkata → Guwahati.

Long-tail guides for NH27 — operators, state hubs, and NH-specific EV charging notes linked to this route.
Leave Kolkata at 88–92% SOC with your real vehicle preset selected (not a random long-range SUV). For ~1030 km on NH27, EV Grids will place DC searches when estimated SOC crosses your threshold. Siliguri is a common overnight anchor. Verify backups — fewer DC sites in remote NH27 segments. Charge to what the next leg needs — often 80–90% — then open Google Maps with your chosen primary and backup as waypoints toward Guwahati.

Kolkata to Guwahati covers about 1030 km in 16–18 hours on NH27 (Northeast India). Long east–northeast link — plan as a two-day drive with an overnight hub. Real consumption still depends on speed, AC, payload, and elevation — enter Wh/km from recent drives instead of brochure range.
NH27 toward the Northeast has genuine sparse stretches. Split long days; Siliguri-style hubs matter more than brochure range.
~1030 km is a multi-stop or overnight drive. Do not treat it as one heroic day in a 40 kWh car. Use via points or two saved trips (for example an intermediate city with hotels). Every stop still needs a backup — a dead gun at 10 p.m. is worse than a dead gun at noon.
Local notes drivers actually use: Siliguri is a common overnight anchor. Verify backups — fewer DC sites in remote NH27 segments.
Humidity and pre-monsoon storms on NH16/NH19 matter. Do not assume a Bengal pin is as reliable as a Hyderabad–Bangalore plaza.
Open Plan now to pre-fill Kolkata and Guwahati. Pick your vehicle, set start SOC honestly, and keep search threshold above reserve. Prefer lower-cost if you have memberships; Fastest if you only want high-kW DC.
This is an EV Grids calculation, not an observation: 1030 km at roughly 165 Wh/km needs on the order of 170 kWh of road energy, and the planner keeps a 20% reserve in hand.
A compact (about 40 kWh usable) pack reaches about 195 km before reserve, which puts this leg at about 5 DC sessions. A mid-size (about 50 kWh usable) pack reaches about 240 km before reserve, which puts this leg at about 4 DC sessions. A long-range (about 70 kWh usable) pack reaches about 340 km before reserve, which puts this leg at about 3 DC sessions.
At 1030 km, treat this as two driving days of roughly 515 km rather than one continuous state-of-charge walk. Decide where you will sleep before you decide where you will charge.
Drive faster, run the air conditioning harder, or load the car and every number above moves the wrong way. Enter your own Wh/km on the planner and it will re-space the stops for NH27 accordingly.
On NH27 you will typically see a mix of Tata Power, Jio-BP Pulse, Statiq, ChargeZone, plaza DISCOM guns, and the occasional mall DC. EV Grids ranks by detour and reliability, not brand loyalty. Memberships change ₹/kWh; they do not reserve a stall.
Do not wait indefinitely at a dark site between Kolkata and Guwahati. Use the backup you already selected; if a swap breaks a later leg, use Fix trip. Keep operator apps logged in. Hotel or mall Type 2 is a valid recovery if you have hours — better than a tow.
Report a permanently closed or moved pin via EV Grids feedback with this corridor slug (kolkata-to-guwahati) so badges and ranking can be updated.
