Charging an EV at home is significantly cheaper than refilling a petrol or diesel car. A typical electric car with a 30 kWh battery pack costs around ₹180 to ₹240 for a full 250 km range, which works out to just ₹0.80 to ₹1.10 per kilometer!
1. Slow 3.3 kW AC vs Fast 7.4 kW Wallbox
- A standard 16A 3.3kW socket takes 8 to 10 hours for a full charge overnight.
