❓ Frequently Asked Questions
Quick Answers
Common questions about EV charging standards in India answered simply
Q: Which charging standard should I choose for my first EV in India?
A:
For most Indian buyers, vehicles supporting both Bharat AC-001 and CCS2 (like Tata Nexon EV, MG ZS EV) offer the best combination of current infrastructure access and future compatibility. This dual support ensures you can charge at maximum locations.
Q: Is it safe to charge my EV using a regular home socket with an adapter?
A:
No, using regular 15A sockets for EV charging is unsafe and inefficient. EV charging requires dedicated circuits with proper earthing, RCD protection, and suitable current ratings. Always install a proper AC charging point.
Q: How much does it cost to install home charging for different standards?
A:
AC charging setup costs ₹20,000-65,000 including charger and installation. Bharat AC-001 chargers are typically ₹15,000-35,000, while Type 2/CCS2 chargers range ₹25,000-50,000. Installation costs ₹5,000-15,000 depending on electrical work required.
Q: Can I use international EV chargers with Indian EVs when traveling abroad?
A:
It depends on your vehicle's charging standards. Vehicles with CCS2 support can use European chargers with adapters. However, Bharat-only vehicles may have limited compatibility. Always check your vehicle's international charging capability before travel.
Q: Will Bharat charging standards become obsolete as international standards grow?
A:
Bharat standards are likely to remain relevant for affordable EVs and mass-market vehicles in India. Many manufacturers are adopting dual-standard approaches. The government continues to support Bharat standards for cost-effective EV adoption.
Q: How do I find compatible charging stations during long trips?
A:
Use apps like PlugShare, ChargeEV, or your vehicle manufacturer's app to find compatible charging stations. Always verify connector types and power ratings before starting your journey. Plan for backup charging options along your route.
Q: What electrical upgrades are needed in apartments for EV charging?
A:
Most apartments need dedicated MCBs, RCD protection, and possibly electrical panel upgrades. For multiple charging points, load management systems prevent overloading. Consult an electrical engineer for proper assessment and compliance with local electrical codes.
