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.
Ranked by estimated charging-stop count on ~570 km via NH19, 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
Hyundai Creta Electric
~390 km range · Typically 1 DC stop
The ~570 km drive is longer than one comfortable leg in a Hyundai Creta Electric. EV Grids estimates one DC session on NH19 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 → Patna.
Popular searches for Kolkata → Patna — each page answers yes/no, typical charging stops, and opens the planner.
Long-tail guides for NH19 — 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 ~570 km on NH19, EV Grids will place DC searches when estimated SOC crosses your threshold. Durgapur–Asansol belt possible first stop zone. Verify chargers on PlugShare before relying on a single pin. Charge to what the next leg needs — often 80–90% — then open Google Maps with your chosen primary and backup as waypoints toward Patna.
Illustrative only — open Plan now above for ranked stops with your vehicle preset and live charger data.
Kolkata to Patna covers about 570 km in 9–10 hours on NH19 (East India). Classic GT Road segment into Bihar. Real consumption still depends on speed, AC, payload, and elevation — enter Wh/km from recent drives instead of brochure range.
NH19 / GT Road segments in the east still need more verification than Deccan IT corridors — do not rely on a single pin.
At ~570 km you should assume two DC sessions for mass-market Indian EVs, or one long session plus a top-up for 75 kWh-class SUVs. Split mentally into halves; if the second half includes a ghat, charge higher at the last plains stop.
Local notes drivers actually use: Durgapur–Asansol belt possible first stop zone. Verify chargers on PlugShare before relying on a single pin.
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 Patna. 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: 570 km at roughly 165 Wh/km needs on the order of 94 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 2 DC sessions. A mid-size (about 50 kWh usable) pack reaches about 240 km before reserve, which puts this leg at about 2 DC sessions. A long-range (about 70 kWh usable) pack reaches about 340 km before reserve, which puts this leg at about 1 DC session.
Split 570 km into thirds of roughly 190 km. One stop late in the first third and one early in the last third spaces the charging better than a single long halt in the middle.
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 NH19 accordingly.
On NH19 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 Patna. 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-patna) so badges and ranking can be updated.
