EV Range & Charging Calculator
Find out how far an electric vehicle will really take you — and how long it takes to charge. Pick a model, set driving style, AC, terrain and charge level for a realistic range band instead of the optimistic ARAI sticker.

Estimated full-charge range
For the Tata Nexon EV under your conditions — roughly 59% of the 489 km ARAI figure.

Estimate only. Real range and charge times depend on payload, tyre pressure, traffic, battery health, charger output and charging curve. DC times assume tapering above ~80%.
ARAI range vs real-world range
Every EV sold in India quotes a headline range certified under ARAI / MIDC — modest speeds, no AC, gentle acceleration and a new battery. That number is useful for comparing models, but consistently higher than daily driving. As a working rule, most EVs deliver roughly 20–30% less than ARAI in mixed use, and more if you cruise hard with the AC on. Treat the claimed figure as a ceiling, not an average.
What affects your real range
Speed, AC/heating, terrain and load, temperature, driving style and battery health all stack. Highway speeds are thirstier (drag rises with the square of speed); city stop-go often recovers energy via regen. Cabin AC is often the biggest accessory load in Indian summers.
How charging time works
AC charging (home socket or wall box) is for overnight top-ups — roughly battery kWh ÷ charger kW. DC fast charging is for road trips; headlines are usually 10–80% because power tapers above 80%. On long drives, charging to ~80% and moving on is usually smarter than waiting for 100%.

Tips to maximise range
- Drive smoothly. Gentle acceleration and anticipation beat hard launches.
- Keep speeds moderate. 80–90 km/h vs 110–120 km/h can add a meaningful chunk.
- Pre-cool while plugged in so the big AC load doesn’t come from the pack.
- Check tyre pressure — under-inflation quietly eats range.
- Use eco and regen modes in stop-go traffic.
Frequently asked questions
ARAI (and the underlying MIDC) range is measured in a controlled lab cycle with low average speeds, no air-conditioning, gentle acceleration and a fresh battery. Real driving — highway speeds, AC, traffic, hills, a full load — uses more energy per km, so most EVs return roughly 20–30% less than the claimed figure. Treat ARAI as a comparison yardstick between models, not a promise of what you'll see on the road.
A quick rule of thumb is ARAI × 0.7–0.8 for mixed driving, or as low as 0.6 on highways with AC. This calculator starts from a realistic base and adjusts for driving style, AC use, route and temperature so you get a usable band rather than a single optimistic sticker number.
It depends on the charger. A 3.3 kW home AC point can take 8–15 hours for a full car battery, a 7.4 kW wall box roughly 5–9 hours, and a 50–150 kW DC fast charger can take a typical EV from 10% to 80% in about 30–60 minutes. DC slows (tapers) sharply above 80%.
Yes. Cabin air-conditioning is one of the biggest non-driving loads and can cut real range by 5% in mild weather to 15–20% on a peak-summer day. Pre-cool while plugged in so the big initial load comes from the grid, not the battery.
Both do. Lithium-ion packs deliver less energy when cold, while extreme heat increases cooling and AC load. In India the dominant factor is summer heat and heavy AC; expect your worst real-world range on the hottest and coldest days.
Significantly. Hard acceleration and high cruising speeds raise consumption because aerodynamic drag rises with the square of speed. Smooth inputs, moderate speeds and regenerative braking in city traffic can easily add 10–20% versus an aggressive style.
Yes — and it's normal. The BMS tapers power as the pack fills, so the last 20% can take nearly as long as the first 60–70%. On a road trip it's usually faster overall to charge to about 80% and move on.
Over the years a pack gradually loses a little usable capacity. Most modern EV batteries are warranted to retain around 70% after about 8 years or 1.5–1.6 lakh km; real-world degradation is usually gentle if you avoid constant 100% charging and frequent rapid charging in extreme heat.
All figures are indicative estimates only. Actual range and charging times vary with the vehicle, conditions, charger and battery health.
