The EV running cost per km can be calculated by dividing the total energy cost for charging the vehicle by its range, considering factors like battery capacity, electricity rates, and driving frequency. Typically, this cost ranges from around 1 to 3 INR per km, depending on local electricity prices and vehicle efficiency.
To accurately calculate the electric vehicle (EV) running cost per kilometer, you need to consider several key factors. According to the EV calculator on HT Auto, the primary inputs include the vehicle's battery capacity, the electricity cost per unit (kWh), the vehicle's range, and the frequency of use. The basic formula involves dividing the total cost of charging (battery capacity in kWh multiplied by the cost per kWh) by the vehicle's range in kilometers, giving the cost per km. For example, if an EV has a battery capacity of 40 kWh, electricity costs ₹8 per kWh, and the vehicle's range is 300 km, then the cost per km is (40 kWh * ₹8) / 300 km = ₹1.07 per km [1]. Additional sources like The Economic Times' EV calculator also emphasize that the running cost depends heavily on local electricity rates, vehicle efficiency (kWh per km), and charging habits. They suggest that EVs generally cost between ₹0.80 to ₹2.50 per km in India, with variations based on electricity prices and vehicle models [2]. The journey cost calculator from NITI Aayog highlights that EVs tend to have significantly lower operational costs compared to internal combustion engine (ICE) vehicles, primarily due to lower fuel and maintenance costs [3]. Similarly, Solar Citizens' EV savings calculator indicates that the cost per km can be optimized further with solar energy, reducing expenses even more [4]. In summary, calculating EV running costs per km involves dividing the total energy expenditure for a full charge by the vehicle's range, adjusted for local electricity rates and vehicle efficiency. The typical range in India, for example, is approximately ₹1 to ₹2.50 per km, but this varies based on specific vehicle and energy costs.
