Frequently Asked Questions

How long does it take to charge a 47 kWh EV battery at 3 kW?

Charging a 47 kWh electric vehicle battery from 10% to 80% on a 3.0 kW (230V 13A UK 3-Pin Plug) takes approximately 12h 11m (or 17h 48m for a full 0% to 100% charge including charger efficiency and BMS tapering).

What breaker size is required for a 3 kW EV charger?

At 240V (1-Phase), a 3 kW charger draws 12.5A continuously, requiring a 16A breaker under US NEC 625.41 (125% continuous load rule) or a 13A breaker under European IEC/NEK standards.
