Frequently Asked Questions

How long does it take to charge a 100 kWh EV battery at 11 kW?

Charging a 100 kWh electric vehicle battery from 10% to 80% on a 11 kW (400V 16A 3-Phase European/Nordic Wallbox) takes approximately 7h 04m (or 10h 20m for a full 0% to 100% charge including charger efficiency and BMS tapering).

What breaker size is required for a 11 kW EV charger?

At 400V (3-Phase), a 11 kW charger draws 15.9A continuously, requiring a 20A breaker under US NEC 625.41 (125% continuous load rule) or a 16A breaker under European IEC/NEK standards.
