The prices of petrol and diesel are continuously increasing in the country, causing concern among the public. As a result, people are turning to electric vehicles (EVs) as an alternative.

However, EVs are generally more expensive than their petrol and diesel counterparts. If you are on a budget, there is a solution. Several companies in the market specialize in converting existing petrol and diesel cars into electric cars, offering a more affordable option.

Conversion Process and Cost

Converting an ordinary car into an electric car typically costs around Rs 4-5 lakh. The price depends on the wattage of the motor installed in the vehicle. Most conversion companies are based in Hyderabad and are involved in manufacturing electric vehicle parts.

The process involves installing a motor, controller, roller, and battery to transform a regular car into an electric one. The higher the wattage of the motor and battery, the higher the expense. For example, installing a 20 kW electric motor and a 12 kW lithium-ion battery could cost up to Rs 4 lakh.

Cost Comparison

Comparing the cost per kilometer, we can take the example of the Tata Nexon, which offers petrol, diesel, and electric options.

The petrol and diesel variants have a mileage of 16-22 kilometers per liter. Assuming a petrol price of Rs 100 per liter and a mileage of 16 kmpl, the cost per kilometer is 6.25 paise.

For diesel priced at Rs 95 per liter and a mileage of 22 kilometers, the cost per kilometer is Rs 4.31. In contrast, the Tata Nexon EV consumes 30.2 units of electricity for a full charge.

Assuming an electricity rate of Rs 6 per unit, the cost to fully charge it is Rs 181.2, allowing it to run approximately 300 kilometers. Therefore, the cost per kilometer is 60 paise.


Converting a regular car into an electric vehicle offers a cost-effective alternative to purchasing a new EV. The cost per kilometer for an electric car is considerably lower than that of a petrol or diesel car. While the example used the Tata Nexon, similar cost figures apply to converted cars as new parts are installed. As petrol and diesel prices continue to rise, the conversion option provides a way for individuals to embrace electric vehicles without breaking their budget.
