Formulas

DC: kW to Amps

I(A) = 1000 × P(kW) ÷ V(V)

1000 × 579.45 ÷ 460 = 579,448 ÷ 460 = 1,259.67 A

AC Single Phase (PF = 0.85)

I(A) = 1000 × P(kW) ÷ (PF × V(V))

579,448 ÷ (0.85 × 460) = 579,448 ÷ 391 = 1,481.96 A

AC Three Phase (PF = 0.85)

I(A) = 1000 × P(kW) ÷ (√3 × PF × VL-L), where VL-L is the line-to-line voltage

579,448 ÷ (1.732 × 0.85 × 460) = 579,448 ÷ 677.21 = 855.61 A

AC Conversion Comparison

On DC, 579.45kW at 460V draws 1,259.67A. AC single-phase at PF 0.85 pulls 1,481.96A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 855.61A per line since the same 579.45kW is shared across three conductors instead of one.

Same kW, Other Voltages

Each destination page leads with the interpretation most common for that voltage, so the amps shown below use the same basis as the page you'd land on: single-phase for residential voltages, three-phase for commercial/industrial panel voltages, DC for low-voltage.

Frequently Asked Questions

579.45 kW at 460V draws about 855.61 amps on an AC three-phase circuit at PF 0.85. Alternate cases at the same voltage: 1,259.67A on DC, 1,481.96A on AC single-phase.
460V is commercial/industrial panel voltage, not a typical AC EVSE feed to a vehicle. On three-phase 460V, 579.45 kW works out to about 855.61A per line (three-phase at PF 0.85). In practice, 400-480V three-phase is usually the AC input to a DC fast charger (50-350 kW CCS/NACS stations like Tesla Superchargers), which rectifies to DC and delivers that directly to the vehicle, rather than an AC EVSE connector. A 579.45 kW figure at 460V is most likely the AC feed to a smaller commercial cabinet or the control-side input of a larger DC fast charger, not an at-the-car AC current.
579.45 kW equals 579,448 watts. Multiply kilowatts by 1000.
579.45 kW costs $98.51 per hour at $0.17/kWh (US residential average, last reviewed April 2026). At 8 hours/day that is $23,641.48 per month.
579.45 kW is typically three-phase in commercial and industrial settings.
