EV Charging Time Calculator
Estimate accurate charging duration from slow 3.3kW home sockets up to 60kW+ ultra-fast DC highway stations with BMS curve tapering.
Calculate EV Charging Duration
Select your EV, pick a charger output rating, and set your start and target battery levels.
Auto-populates battery capacity, charging limits, and real-world efficiency.
Adjust starting and target battery levels to calculate session energy.
To charge Nexon EV from 10% to 80% using a 50 kW charger.
How EV Charging Time & Curves Work
Linear Phase (0% to 80%)
During the initial Constant Current (CC) phase, the EV absorbs power at the maximum negotiated rate:
A 50kW DC charger feeding a 40.5 kWh battery from 10% to 80% transfers ~28.3 kWh in approx 40 minutes.
Tapering Phase (80% to 100%)
Once the battery pack hits 80% State of Charge, the BMS reduces current to protect battery cells.
Charging the remaining 20% (80% to 100%) can often take almost as long as going from 10% to 80%.
