Frequently Asked Questions

How long does it take to charge a 82 kWh EV battery at 11.5 kW?

Charging a 82 kWh electric vehicle battery from 10% to 80% on a 11.5 kW (240V 48A Hardwired Tesla Wall Connector) takes approximately 5h 33m (or 8h 06m for a full 0% to 100% charge including charger efficiency and BMS tapering).

What breaker size is required for a 11.5 kW EV charger?

At 240V (1-Phase), a 11.5 kW charger draws 47.9A continuously, requiring a 60A breaker under US NEC 625.41 (125% continuous load rule) or a 50A breaker under European IEC/NEK standards.
