How much does it cost to charge an electric car at home in India?

Multiply the battery size by your electricity tariff and add about 10% for charging losses. A 40.5 kWh Tata Nexon EV at ₹7 per unit costs roughly ₹310–₹320 for a full charge at home.

Is charging an EV cheaper than petrol?

Yes — typically 80–90% cheaper per km when charged at home. A mid-size EV runs at about ₹1 per km at ₹7 per unit, while a comparable petrol car costs ₹7 or more per km.

Do Indian states have special EV charging tariffs?

Several states (Delhi, Maharashtra, Karnataka, UP and others) have separate LT EV-charging categories or Time-of-Day discounts for night charging, often cheaper than the top domestic slab. Check your DISCOM's tariff schedule.

How long does home EV charging take?

On a regular 15A socket (about 3.3 kW), a 40 kWh car battery takes roughly 12 hours for a full charge. A 7.2 kW AC wallbox roughly halves that. Scooter batteries (3–4 kWh) charge in about an hour or two.

Home charging is billed at your domestic slab rate — EV units land on top of your household usage, so use your top-slab rate for accuracy (find it on our tariff pages). Several states (Delhi, Maharashtra, Karnataka, UP and others) have dedicated EV-charging categories or night Time-of-Day discounts that can cut the rate further. Installing a 7.2 kW wallbox usually needs a sanctioned-load upgrade from your DISCOM — check before you install. Cost and time per charge follow your chosen charge level (most owners stop near 80% for battery health); your monthly cost tracks the kilometres you drive, so the slider doesn't change it.
