It depends how are you charging, if you are charging in home, the Long range Nexon has 40kWh battery means 40 units, also the price of single unit varies from city to city, we have Rs 10 per unit so the cost for one full charge is 40x10= Rs 400, and the average range the owner gets is 330-350 Km in one full charge, which results to Rs1.2 per Km
