Home charging cost — FAQs
How much does it cost to charge an electric car at home in India?+−
It depends on your battery size and electricity tariff. At roughly ₹8 per unit, a 40 kWh battery costs about ₹320 for a full charge (0–100%) — usually well under ₹1.5 per km. Enter your car and tariff above for your exact figure.
Is home charging cheaper than public fast charging?+−
Yes, significantly. Home AC charging on a domestic tariff (~₹8/unit) is far cheaper than public DC fast charging (often ₹18–24/unit), though fast charging is much quicker. The calculator shows both so you can compare.
How much does it cost to install a home EV charger?+−
A basic OEM 3.3 kW charger often comes with the car; a 7.4 kW wallbox plus installation — cabling, protection, labour and any load upgrade — typically runs into tens of thousands of rupees depending on the distance from your meter. The “Setup cost” tab estimates it for your situation.
Do I need a special connection to charge an EV at home?+−
Most EVs can charge on a standard 15A socket (slow), but a dedicated wallbox on its own circuit is faster and safer. Occasionally a sanctioned-load upgrade is needed — the setup calculator includes these one-time costs.
