Charger Speed Calculator: How Long to Charge Your Specific EV in India (2026 Guide)
Wondering “how long does it take to charge a Tata Nexon EV with a 7kW home charger in Bengaluru” or “EV charging time for MG Windsor EV on 50kW DC fast charger India”? With India’s EV adoption soaring in 2026 — led by models like the Tata Nexon EV (45 kWh, up to 489 km range), MG Windsor EV (up to 52.9 kWh, 449 km claimed), Mahindra BE 6 (79 kWh beast), and scooters like Ola S1 Pro and Ather 450X — accurate charging time estimates eliminate guesswork and range anxiety.
Our EV charger speed calculator uses the proven formula:
Charging Time (hours) = Battery Capacity (kWh) × (Target % – Current %) / (Charger Power (kW) × Efficiency)
(Real-world efficiency: ~90% for AC home charging in Indian conditions; factor in 10-15% slowdown during 35°C+ summers common in Karnataka.)
For example:
Tata Nexon EV 45 kWh on a 7.2kW wallbox charger (popular home upgrade in Bengaluru apartments): ~6.6–7 hours for 10-100%.
MG Windsor EV on 50kW DC public charger: 20-80% in ~35 minutes (real-world tested).
Ola S1 Pro scooter (4-5 kWh): Full home charge in 5-6 hours with standard 3.3 kW.
