Frequently Asked Questions
How long does it take to charge a 100 kWh EV battery at 3.6 kW?
Charging a 100 kWh electric vehicle battery from 10% to 80% on a 3.6 kW (230V 16A Single-Phase) takes approximately 21h 36m (or 31h 34m for a full 0% to 100% charge including charger efficiency and BMS tapering).
What breaker size is required for a 3.6 kW EV charger?
At 240V (1-Phase), a 3.6 kW charger draws 15.0A continuously, requiring a 20A breaker under US NEC 625.41 (125% continuous load rule) or a 15A breaker under European IEC/NEK standards.
