An EV has a higher upfront cost of procurement as compared to its ICE counterpart. However, the
cost of charging, maintaining and operating an EV is lower than the ICE vehicle which in turns
reduces the TCO of an EV.
For example, Tata Tigor and Tata Tigor EV has been considered for calculation. Tata Tigor has a
claimed range of approximately 20 kms per litre. Assuming, a running of 100 kms, it would consume
around 5 litres of petrol. Assuming the cost of petrol of INR 86.95 per litre, as of 08 Feb 2021. Hence,
the cost of travelling 100 kms is INR 434.75. Tata Tigor EV, with a total battery capacity of 21.5
kWh, the total cost of charging the EV would be 21.5 kWh x INR 4.5 per kWh (Assuming EV home
charging tariff for Delhi), i.e. around INR 96.75. Hence it is economical to operate an EV than ICE
vehicle.
