What EV Charger Do You Need for a 2027 Cadillac Optiq V Series 11kW Charger?
Wiring a 60 amp breaker and hardwiring a Level 2 unit is mandatory for your car. You need a 48 amp charger to reach the maximum onboard rate of 11.5 kW. The EPA test measures charge time at 9.5 hours, yielding 29 miles of range per hour. Charging at the full rate brings the 101.9 kWh battery from empty to full in 8.9 hours at 31 miles of range per hour.
The numbers
| Maximum AC charging rate | 11.5 kW (48 A) |
|---|---|
| Charger size to buy | 48 A |
| Circuit breaker required | 60 A |
| Outlet / connection | hardwired (a 48 A EVSE must be hardwired -- no household receptacle is rated for it) |
| Charge port | J1772 |
| Full charge on Level 2 | about 8.9 hours |
| Range added per hour (Level 2) | about 31 miles |
| Full charge on a 120 V outlet | about 71 hours |
| Range added per hour (120 V) | about 3.9 miles |
| EPA rated range | 278 miles |
| Energy for a full charge | about 101.9 kWh at the wall |
Why 48 amps and not more
Your car draws up to 48 amps on Level 2 equipment. Buying a smaller charger slows down your daily turnaround. Plugging into a higher amperage unit will not speed up the vehicle because the onboard charger caps the intake at 48 amps. You get 31 miles of range per hour at this amperage. That speed easily covers overnight refills.
What the install involves
A 48 amp EVSE requires hardwiring because no household receptacle is rated for that continuous load. You must bring in a licensed electrician to run the circuit and land it on a 60 amp breaker in your panel. The electrician needs to check that your electrical panel has spare capacity for the heavy load. Mount the charger on the wall near where you park.

Common questions
- What kind of plug does this car use?
- The vehicle has a J1772 connector. This model year falls in the industry transition to NACS, so many vehicles ship with a NACS port and include a J1772 adapter. Confirm your car port before buying.
- Can I use a standard wall outlet?
- You can plug into a standard household outlet for Level 1 charging, but it delivers only 3.9 miles of range per hour. A full charge on Level 1 takes 71 hours. You need a Level 2 setup for practical daily driving.
- Why does the EPA charge time differ from the peak rate?
- The EPA test runs at 9.5 hours and 29 miles per hour. The car's peak AC rate finishes a full charge in 8.9 hours at 31 miles per hour. Testing conditions vary from real world maximum output.
- Do I need a special adapter for Tesla chargers?
- You can buy a Tesla to J1772 adapter rated for 80 amps. This lets your J1772 car use Tesla Destination Chargers and Wall Connectors on the road.
