EV Trip Charging Stop Planner
Estimate whether the energy needed for a specific drive fits between your start and arrival charge targets.
Method and units
Trip energy = distance × consumption ÷ 100. Starting energy above the arrival reserve is deducted first; remaining energy is the charge needed. A session is battery capacity × (stop target − arrival reserve). Sessions are rounded up; charging hours divide energy by the user's average charging power.
Worked example
For 300 km at 18 kWh/100 km, a 60 kWh pack, 80% start, 20% arrival reserve, 80% stop target and 50 kW average, trip demand is 54 kWh. The 36 kWh above reserve at departure leaves 18 kWh to replenish: one modeled session taking 21.6 minutes.
Supported inputs and interpretation
Distance 0.1–5,000 km; consumption 1–100 kWh/100 km; capacity 1–300 kWh; SOC 0–100%; average power 0.1–500 kW. Results are rounded for display only; internal calculations retain full JavaScript precision. Entered measurements and assumptions determine the answer.
References and limitations
The equations here use the stated unit conversions and geometric or accounting relationships; no empirical vehicle limits or manufacturer presets are supplied.
This is energy arithmetic, not a route, charger-availability, weather, elevation, speed, battery-temperature or vehicle-range guarantee. Actual charge power varies; don't treat this as proof a route is feasible.
