DC fast charging slows significantly above 80%, so real fast-charge sessions to 100% take longer than a straight-line estimate. A 10% charging loss is included. India's public fast-charging network is growing but station density and uptime still vary a lot by city.

How charging time is calculated.

Energy Needed = Battery × (Target% − Current%) Time (hours) = Energy Needed ÷ (Charger kW × 0.9) 0.9 accounts for ~10% charging losses (heat, AC/DC conversion).

Frequently asked questions.

What is the difference between home AC, public AC, and DC fast charging in India?

A standard home 15A socket is slowest (~2-3 km of range per hour). A dedicated home or public AC wallbox (3.3-7.2 kW) is the most common overnight option. DC fast charging (25-150+ kW) is available at a growing number of public stations and delivers rapid top-ups for highway trips.

Why does charging slow down near 100%?

To protect the battery, the charging rate tapers as the pack fills. On DC fast chargers, the last 20% can take as long as the first 60%, which is why 80% is the practical fast-charge target.

Can I charge a big battery on a home outlet?

Technically yes, but a regular 15A household socket may take 20+ hours for a large pack. A dedicated AC wallbox is strongly recommended for any EV with a battery over ~30 kWh.
