Northeast India EV road trip — Kolkata to Assam and beyond

Kolkata → Guwahati is roughly 1,000 km — plan an overnight DC + hotel stop near Siliguri or the Malda belt rather than one marathon drive.

Siliguri → Gangtok and Guwahati → Shillong are short on distance but heavy on elevation — charge to 90%+ before every hill climb.

Assam plains (Guwahati, Dibrugarh) are improving; Sikkim and hill towns still need manual verification on operator apps before you commit.

Use red reliability badges as skip signals when a backup exists within 20 km. Report wrong or dead sites via EV Grids feedback.

Practice on Kolkata → Siliguri before attempting the full run to Guwahati. Enable overnight stop mode if you need 100% SOC at a hotel.

Siliguri, Guwahati, and (to a lesser extent) Shillong/Dibrugarh are where you reset the pack. Hill towns are where you spend the buffer you brought. That is the opposite of NH48 thinking.

Permits, landslides, and early sunsets change the day length. Plan fewer kilometres than a Deccan Saturday. Charge to 100% overnight whenever a hotel has AC — DC in the hills may not exist at 7 a.m.

Call or app-check the one charger you are depending on in a hill town. EV Grids will still rank what listings exist; listings in the Northeast go stale. Carry the expectation that a day may end on Type 2.

The Northeast has real gaps between fast-charging locations, not merely inconvenient ones. Distances that look modest on a map can take far longer because of terrain and road quality, which means arrival times and charging opportunities both need more slack than plains driving.

Split days shorter than you would on NH44. Hub towns such as Siliguri matter more than brochure range: reaching a place with several options beats reaching a place with one.

Check road status close to departure. Landslides and weather closures are a normal part of planning here, and a closure can add distance that no state of charge margin was designed for. Carry the operator apps you may need, since coverage for signing up on the spot is not guaranteed.

Treat AC charging at accommodation as part of the plan rather than a fallback. In sparse regions, an overnight charge is often the most reliable energy of the entire day.
