❓ Frequently Asked Questions (FAQ)
1. How much cheaper is EV charging vs petrol?
EVs are 5-7x cheaper! Home charging costs just ₹1-1.5/km while petrol cars cost ₹6-7/km. On 50km daily run, you save ₹8,000-10,000/month with an EV. Even public charging at ₹15/kWh is 3-4x cheaper than petrol.
2. What is charging efficiency and why does it matter?
Charging isn't 100% efficient. 10-25% energy is lost as heat during AC-to-DC conversion. Home charging is 85-90% efficient, DC fast charging is 80-85%. This means a 50kWh battery may need 55-60kWh of electricity to fully charge.
3. Public charging vs Home charging - cost difference?
Home: ₹7-10/kWh (cheapest). Public: ₹15-20/kWh (moderate). DC Fast: ₹18-25/kWh (premium). For lowest cost, charge at home overnight. Use public chargers only for highway trips. Office charging is often free or subsidized at ₹5/kWh.
4. How many units does an EV consume per month?
For 50km/day: ~150-200 units/month. Home charging cost: ₹1,200-1,600/month. That's less than most home AC bills! A typical Indian household uses 200-300 units/month, so an EV adds about 50-70% to your electricity bill but saves ₹8,000+ on petrol.
