Driving Conditions
Eco · Flat · City
▾
Driving style
+10% range
Eco driving — smooth acceleration, anticipatory braking, speed moderation. Adds ~10% to real-world range versus normal driving.
Terrain
no impact
Flat roads — no grade resistance penalty. Most urban Indian routes qualify as flat or mild.
Speed profile
+10% range
City speeds — EVs are most efficient at low speed due to regen and low aerodynamic drag. Highway speeds dramatically increase air resistance, cutting range by ~18% vs mixed driving.
Ambient temperature
28°C
-5°C10°C25°C40°C50°C
Optimal range is 20–32°C. Below 20°C, lithium-ion chemistry slows (0.9% loss per °C). Above 32°C, thermal management draws power (0.6% loss per °C).
Climate control
no impact
AC off — no auxiliary power drain. In Indian summers, AC running at 35°C+ can reduce range by 8–12% depending on vehicle type and compressor size.
Traffic conditions
+3% range
Moderate traffic — typical Indian urban arterial roads. Stop-go city traffic (like peak-hour Delhi) reduces EV range by ~12% due to frequent braking cycles despite some regen recovery.
Regenerative braking
no impact
Medium regen — standard one-pedal feel. High regen recovers ~3% more energy in stop-go traffic. Low/off is used on open highways where you rarely brake.
Rain / headwind
no impact
Clear skies — no aerodynamic drag from rain or headwind. A 50 km/h headwind can reduce highway range by 10–16% depending on vehicle frontal area.
Tyre pressure
no impact
Optimal pressure — rolling resistance at spec. Under-inflated tyres by 20% increase rolling resistance ~5%, directly cutting range. Check monthly for best results.
Passenger / payload load20%
0% (solo)50%100% (full)
Every 10% additional payload above empty increases energy consumption by ~1.5–2% through increased rolling resistance and acceleration energy.
Elevation gain per trip100 m
metres
Climbing requires energy proportional to weight × height. 100m gain in a 1,500 kg SUV costs ~0.4 kWh of net energy — partially recovered on the descent via regen.

AC L2 (7.4 kW) — Most common Indian home/office charger. Charges a 30 kWh battery from 20→80% in about 3h 20min. AC charging is nearly linear, with a small efficiency penalty from AC→DC conversion on-board.

AC chargers lose 8–12% to on-board converter heat. DC fast chargers bypass on-board electronics (~5–6% loss). Higher efficiency = less grid energy wasted as heat.

Route planning assumes 100% charge at departure
This answers: "How many stops do I need if I start fully charged?" — the correct way to plan a long trip. Current SOC (Step 1) is for real-time range display only. A journey-end reserve (default 10%) is kept at each leg end.
