Plan road trips for EVs that actually account for elevation, speed and charge taper.
NACSBuddy routes you through the Supercharger network like a flight plan — leg by leg, with arrival SoC, charge times, and "slow to make it" advisories before your battery runs short.
Free to plan. Sign up free to save trips. Connect your car on Pro.
Tell us where you're starting, where you're going, and your vehicle's range and SoC at departure.
The planner treats every Supercharger as a node in a graph and picks stops that stay inside your charging band.
Distance, elevation delta, kWh, arrival SoC and charge time for every segment — plus advisories if you need to slow down.
A 2,000 m climb burns range a flat-road estimator can't see.
Standard nav tools estimate range from a static Wh/mi number. Real consumption is dominated by aerodynamic drag (quadratic in speed) and gravity (mass · g · Δh). Descents partially refund the energy via regen.
NACSBuddy models all three and surfaces a "slow to X mph" advisory whenever your projected arrival SoC drops below your target.
Connect your car via Tessie or Tesla API. Live SoC, in-trip recompute, slow-down alerts.
