EV Charging Time Calculator
How long will your EV actually take to charge? Choose your model, the charger you're plugging into and the battery percentage you're starting from. The result models the real DC power curve — including the taper above 80% — rather than the flat battery÷charger sum most calculators use.

What's limiting the speed
The charger is the limit. The Tata Nexon EV can accept 70 kW, but this 50 kW DC tops out at 50 kW. A more powerful charger would genuinely be faster for this vehicle.
Why you should stop at 80%
The last fifth of the battery can take almost as long as the first three fifths. On a road trip you cover far more ground by unplugging at 80%.
Same charge on every charger
Times model the real DC power curve — power holds near peak then tapers — and include charging losses (~12% AC, ~6% DC). Expect sessions to run a little longer in peak summer heat.
Why battery ÷ charger gives the wrong answer
Battery ÷ charger is fine for AC and badly wrong for DC. A DC session ramps, holds near peak, then tapers deliberately as the pack fills. This calculator walks the charge one percent at a time with a realistic power fraction — which is why 20→80% looks like what owners actually see, and why 80→100% looks so expensive in time.
The two limits: charger power and vehicle acceptance
Whichever ceiling is lower wins. Plug a 50 kW-accepting car into 150 kW and you get 50. Ultra-fast hubs often cost more per unit — if your car cannot use the extra power, you pay a premium for speed you never see. The tool flags which side is the bottleneck.
Typical charging times in India
| Charger | Power | 3 kWh scooter | 40 kWh car (0–100%) | 60 kWh car (20–80%) |
|---|---|---|---|---|
| 15A household socket | 2.3 kW | ~1 hr 30 min | ~19 hr 20 min | — |
| 3.3 kW AC point | 3.3 kW | ~1 hr | ~13 hr 30 min | ~12 hr 5 min |
| 7.4 kW wall box | 7.4 kW | ~27 min | ~6 hr | ~5 hr 25 min |
| 11 kW AC (3-phase) | 11 kW | ~18 min | ~4 hr | ~3 hr 40 min |
| 25 kW DC | 25 kW | — | ~3 hr 15 min | ~2 hr |
| 50 kW DC | 50 kW | — | ~1 hr 40 min | ~1 hr |
| 120 kW DC | 120 kW | — | ~40 min | ~25 min |

Planning charging around your day
For most owners, charging happens while they sleep — a 7.4 kW wall box replaces a full day's driving overnight. On road trips, short stops in the fast part of the curve beat long stops at the slow end: arrive around 10–15% and leave at 70–80%.
Frequently asked questions
It depends far more on the charger than the car. A typical 40 kWh EV takes ~19 hours on a 15A socket, ~13.5 hours on 3.3 kW AC, ~6 hours on a 7.4 kW wall box, and about 45–55 minutes for 20→80% on a 50 kW DC charger. The last stretch from 80→100% on DC can add another ~45 minutes — which is why most owners stop at 80% on the road.
Two limits apply and the lower one wins: charger output and the car’s acceptance rate. Beyond that, the BMS tapers power as the pack fills, when cold, or when hot — so the advertised peak is a best case that typically holds only in the low-to-mid SoC band.
As cells fill, the BMS tapers power sharply to avoid lithium plating. The final 20% can take as long as the first 60%. On a journey you almost always arrive sooner by charging to 80% twice than to 100% once.
Not catastrophic, but not ideal. Fast charging generates more heat, and heat drives long-term degradation — especially in Indian summers. Use DC for journeys and AC for daily top-ups.
Almost — if your car’s onboard charger accepts 7.4 kW. A car limited to 3.3 kW AC will only draw 3.3 kW from a larger wall box. Check acceptance before upgrading.
Most 2–4 kWh scooters take roughly 4–6 hours on a portable household charger. Fast-charge-capable models can reach ~80% in 1–2 hours on a compatible unit. Overnight charging is usually a non-event.
Both do. Cold packs limit current until warm; heat after a highway run can throttle DC heavily. Liquid-cooled cars handle this better than air-cooled designs.
Yes — nearly every EV ships with a portable cable. A 15A socket delivers ~2.3 kW. Have an electrician confirm the wiring is rated for sustained load before relying on overnight charging from an old socket.
Tools to help you decide
Charging times are modelled estimates based on published capacities and acceptance rates, an approximated DC taper curve and typical losses. Real sessions vary with battery temperature, health, ambient conditions and charger output.
