How this service works
Electric vehicle range estimate from battery capacity, consumption and reserve - kilometers and miles
Output
Returns a JSON object containing the estimated driving range in both kilometres and miles, the usable kWh after accounting for the reserve, the original inputs echoed back (battery_kwh, efficiency_kwh_per_100km, reserve_percent), the calculation formula used, and a scope note explaining what the estimate covers and excludes.
Example use cases
Trip feasibility check for EV owner
“I have a Tesla with a 100 kWh battery and it uses about 16 kWh per 100 km — can you calculate how far I can drive if I keep a 10% reserve, in both km and miles?”
Comparing EVs by effective range
“I'm comparing two EVs: one has a 60 kWh battery at 20 kWh per 100 km efficiency, and the other has a 77 kWh battery at 22 kWh per 100 km. Both with a 20% reserve — what's the estimated range for each?”
Fleet route planning with battery reserve
“Our delivery van has a 120 kWh battery and consumes 25 kWh per 100 km. With a mandatory 15% reserve, what's the maximum route distance we can plan for in kilometers?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/transport/ev-range?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, formula-based EV range calculation from first principles (battery size, efficiency, reserve) rather than real-world telemetry or vehicle-specific lookup tables. It is ideal for trip planning tools, EV comparison apps, and fleet management systems where the user knows their vehicle's specs. Prefer this over vehicle database lookups when you want transparent, reproducible math with dual km/miles output.
Side effects
- Missing required query parameters (battery_kwh, efficiency_kwh_per_100km, or reserve_percent) result in an error response
- Non-positive battery_kwh or efficiency values rejected as invalid
- reserve_percent of 100 or more is rejected (must be under 100)
- Non-numeric string values for numeric parameters may cause parse errors
- Payment not included or insufficient USDC triggers x402 payment-required response
