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 OPTIQ Premium Luxury AWD specifically, that connector carries up to 11.5 kW at home on Level 2 and up to 150 kW on public DC fast hardware.
Charging speed by circuit size
The Cadillac OPTIQ'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 |

Cadillac OPTIQ charging questions
How long does it take to charge a 2025–2026 Cadillac OPTIQ Premium Luxury AWD on a Level 2 charger?
About 7.4 hours from empty to full at its 11.5 kW onboard-charger ceiling (85 kWh battery ÷ 11.5 kW).
Times scale with amperage - see the circuit-size table above for other settings.
What amperage does a Cadillac OPTIQ draw on Level 2?
At its full 11.5 kW rate, the Cadillac OPTIQ draws about 48A at 240V (kW × 1000 ÷ 240 = amps).
Can a Cadillac OPTIQ use a 48-amp charger?
Not to any real benefit. The Cadillac OPTIQ's onboard charger tops out at 11.5 kW (~48A) - a 48A charger doesn't charge it any faster than one already sized to 48A.

Roughly 328 miles from an 8-hour overnight charge (41 mi/hr × 8 hours), or about 410 miles across a 10-hour window.
What's the DC fast charging ceiling for a Cadillac OPTIQ?
Up to 150 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.
