The exact cost will vary depending on the vehicle and electricity rates. On an average, it will be less than Rs 40 for a full charge for an all-electric car or a scooter. Your overall energy bill will be lowered by driving with electricity.

For example, the Mahindra Verito gives a mileage of 15 kmpl. At Rs 75 per liter of Petrol, the car would need 4 liters to cover 60 kms for a total cost of Rs 300 for the trip.
The Mahindra e2o would need 10 units of power for a full charge of 100 km. At Rs 4 a unit that would be Rs 40.
So there you go, a person driving an EV spends less than Rs 30 to cover 60 kms while a gas powered car would really drill a hole in the wallet. With an EV you pay almost as less as one twelfth of what you’d spend on traveling with a petrol-powered vehicle.
