Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 17.65 ÷ 24 = 17,647 ÷ 24 = 735.29 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

17,647 ÷ (0.85 × 24) = 17,647 ÷ 20.4 = 865.05 A

Resistive (heaters, incandescent)	1	735.29 A
Fluorescent lamps	0.95	735.29 A
LED lighting	0.9	735.29 A
Synchronous motors	0.9	735.29 A
Typical mixed loads	0.85	735.29 A
Induction motors (full load)	0.8	735.29 A
Computers (without PFC)	0.65	735.29 A
Induction motors (no load)	0.35	735.29 A

AC Conversion Comparison

On DC, 17.65kW at 24V draws 735.29A. AC single-phase at PF 0.85 pulls 865.05A because reactive current is added on top of the real power.

Circuit Type	Formula	Result
DC	17,647 ÷ 24	735.29 A
AC Single Phase (PF 0.85)	17,647 ÷ (0.85 × 24)	865.05 A

Frequently Asked Questions

How many amps is 17.65 kW at 24V?expand_more

17.65 kW at 24V draws about 735.29 amps on DC. Alternate cases at the same voltage: 865.05A on AC single-phase.

How does power factor affect the amps for 17.65 kW at 24V?expand_more

On AC single-phase, current scales inversely with power factor. At PF 1.0 (pure resistive, like a heater), 17.65 kW at 24V draws 735.29A. At PF 0.80 (typical induction motor), the same real power draws 919.11A. The extra current is reactive and does no real work, but still flows through the wire and the breaker.

How many amps does a 17.65 kW EV charger draw at 24V?expand_more

At 24V, this is Level 1 territory (120V AC, single-phase, typically 12-16A). A 17.65 kW draw on a standard 120V household outlet is at or above the 1,440W NEC 210.19(A) continuous figure, which is why Level 1 EVSE ships at 1.4-1.9 kW and takes 20+ hours for a full charge. If you need 17.65 kW of charging, you want Level 2 on a 240V dedicated circuit, not 120V.

What is the formula for kW to amps?expand_more

DC: Amps = (kW × 1000) ÷ Volts. AC single-phase: Amps = (kW × 1000) ÷ (Volts × PF). AC three-phase: Amps = (kW × 1000) ÷ (Volts_L-L × √3 × PF).

Is 17.65 kW single-phase or three-phase?expand_more

17.65 kW is typically three-phase in commercial and industrial settings.
