Typical full-speed install
48A charger on a 60A circuit
Reaches this car's 11.5 kW ceiling. Whether your panel has room for that circuit depends on everything else already on it - that's the actual assessment.
Connector
NACS
NACS (North American Charging Standard, originally Tesla's plug) is now the connector most new EVs are shipping with for both home Level 2 and public DC fast charging.
On the Escalade IQ Luxury specifically, that connector carries up to 11.5 kW at home on Level 2 and up to 350 kW on public DC fast hardware.
Charging speed by circuit size
The Cadillac Escalade IQ's onboard charger can't use more than 11.5 kW AC no matter how big the circuit - past 48A, a bigger charger buys you nothing on this car.
| Charger setting | This car actually draws | Range added / hour | 8-hr overnight |
|---|---|---|---|
| 16A | 3.8 kW | ~8 mi | ~64 mi |
| 24A | 5.8 kW | ~12 mi | ~96 mi |
| 32A | 7.7 kW | ~17 mi | ~136 mi |
| 40A | 9.6 kW | ~21 mi | ~168 mi |
| 48A | 11.5 kWcapped by car | ~25 mi | ~200 mi |

Times scale with amperage - see the circuit-size table above for other settings.
What amperage does a Cadillac Escalade IQ draw on Level 2?
At its full 11.5 kW rate, the Cadillac Escalade IQ draws about 48A at 240V (kW × 1000 ÷ 240 = amps).
Can a Cadillac Escalade IQ use a 48-amp charger?

Up to 350 kW on a public DC fast charger - well above its 11.5 kW Level 2 (home) ceiling, though DC fast rates taper as the battery fills.
