Frequently Asked Questions
How long does it take to charge a 45 kWh EV battery at 2.3 kW?
Charging a 45 kWh electric vehicle battery from 10% to 80% on a 2.3 kW (230V 10A Schuko / Granny Charger) takes approximately 15h 13m (or 22h 14m for a full 0% to 100% charge including charger efficiency and BMS tapering).
What breaker size is required for a 2.3 kW EV charger?
At 240V (1-Phase), a 2.3 kW charger draws 9.6A continuously, requiring a 13A breaker under US NEC 625.41 (125% continuous load rule) or a 10A breaker under European IEC/NEK standards.
