How long to charge a Cadillac OPTIQ at home
Typical trim (OPTIQ AWD (11 kW Charger)): 34 kWh/100 mi · EPA range 303 mi · on a 48 A (11.5 kW) charger about 34 mi of range per hour*
EPA lists a 240 V full-charge time of 9.5 h for this trim, which implies an average of roughly 10.8 kW (our estimate, = 103 kWh ÷ 9.5 h). Chargers well above that are unlikely to charge this car faster on AC; check the owner's manual for the onboard charger rating.
Range added by charger size (typical trim)
| Charger | Range per hour | Per 8-hour night | Empty to full EPA range |
|---|---|---|---|
| 12 A at 120 V (Level 1 cord) (1.4 kW) | 4 mi | 34 mi | 71.5 h |
| 16 A at 240 V (3.8 kW) | 11 mi | 90 mi | 26.8 h |
| 24 A at 240 V (5.8 kW) | 17 mi | 136 mi | 17.9 h |
| 32 A at 240 V (7.7 kW) | 23 mi | 181 mi | 13.4 h |
| 40 A at 240 V (9.6 kW) | 28 mi | 226 mi | 10.7 h |
| 48 A at 240 V (11.5 kW) | 34 mi | 271 mi | 8.9 h |
| 64 A at 240 V (15.4 kW) | 45 mi | 361 mi | 6.7 h |
| 80 A at 240 V (19.2 kW) | 56 mi | 452 mi | 5.4 h |
*Estimates: charger kW ÷ EPA kWh/100 mi × 100, assuming the car accepts that power. Charging tapers near 100% and is slower in the cold.

Source: fueleconomy.gov vehicle records (2026, 2027 model years). "Energy for full range" = kWh/100 mi × range ÷ 100, measured at the wall, so it includes charging losses and is not the battery size. Usable battery capacity is not in EPA data (data gap).
Will a bigger charger charge it faster? (per trim)
Times are empty to full EPA range. They are capped at the onboard charger rating only where EPA's own trim name states it. Otherwise they assume the car accepts the charger's full power, which may overstate the gain from 48 A and 80 A units.

† Only if the car accepts that much power. This charger is more than 10% above the average power implied by EPA's own 240 V time, so treat EPA's time as the realistic figure.
