Pro Tips to Minimize Charging Costs
Charge at Home:
Use residential electricity rates for the lowest cost per kWh.
Take Advantage of Free Charging:
Some malls, offices, and parking lots offer free or discounted charging.
Optimize Charging Habits:
Avoid frequent DC fast charging to reduce costs and preserve battery life.
Monitor Energy Use:
Use apps like Tata Power EZ Charge or PlugShare to find affordable public charging stations.
Conclusion
The cost of charging an EV in India varies based on location, charging method, and electricity rates. On average, charging at home costs ₹1–₹2 per km, while public or fast charging may cost ₹3–₹4 per km. Despite these variations, EVs remain significantly cheaper to operate compared to petrol or diesel cars, offering long-term savings and environmental benefits.
Switching to an EV not only reduces running costs but also supports sustainable transportation in India. By choosing the right charging solutions and habits, you can maximize the affordability and efficiency of your EV.
