Frequently Asked Questions

How long does it take to charge a 91 kWh EV battery at 9.6 kW?

Charging a 91 kWh electric vehicle battery from 10% to 80% on a 9.6 kW (240V 40A Level 2 NEMA 14-50) takes approximately 7h 22m (or 10h 46m for a full 0% to 100% charge including charger efficiency and BMS tapering).

What breaker size is required for a 9.6 kW EV charger?

At 240V (1-Phase), a 9.6 kW charger draws 40.0A continuously, requiring a 50A breaker under US NEC 625.41 (125% continuous load rule) or a 40A breaker under European IEC/NEK standards.
