Question 1

Is vehicle to grid technology available in India today?

Accepted Answer

Only as pilots. ISGF ran South Asia's first AC V2G demonstration in May 2026 with four retrofitted Tata Nexon EVs at three Delhi discoms. No notified tariff lets a fleet sell exported energy.

Question 2

Can an existing depot charger be upgraded to V2G?

Accepted Answer

No. Bidirectional operation needs different power electronics, not different firmware. The CEA puts the interface at three to five times the cost of a unidirectional smart charger — a replacement decision, not an upgrade.

Question 3

Does V2G void an EV battery warranty?

Accepted Answer

It depends on the OEM's written terms. Typical cover guarantees 70% capacity at 8–10 years or 160,000 km, and manufacturers limit risk by allowing only vehicle-to-home use, requiring approved chargers or capping throughput.

Question 4

What is the difference between V1G and V2G?

Accepted Answer

V1G modulates how fast a vehicle draws power, always one way; V2G exports energy from the pack to the grid. V1G runs on standard chargers and can cut peak depot demand by up to 60%; V2G needs bidirectional hardware on both sides.
