Frequently Asked Questions

How long does it take to charge a 50 kWh EV battery at 75 kW?

Charging a 50 kWh electric vehicle battery from 10% to 80% on a 75 kW (Urban DC Fast Charger) takes approximately 33 min (or 57 min for a full 0% to 100% charge including charger efficiency and BMS tapering).

What breaker size is required for a 75 kW EV charger?

At 400V (3-Phase), a 75 kW charger draws 108.3A continuously, requiring a 150A breaker under US NEC 625.41 (125% continuous load rule) or a 110A breaker under European IEC/NEK standards.
