What EV Charger Do You Need for a 2027 Cadillac Lyriq 11kW Charger?
Forty-eight amps is the correct ceiling for your battery. Buying a larger unit wastes money because the onboard charger cannot draw past 48 amperes. Match the recommended EVSE amps to get the fastest Level 2 speeds.
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 10.4 hours |
| Range added per hour (Level 2) | about 31 miles |
| Full charge on a 120 V outlet | about 83 hours |
| Range added per hour (120 V) | about 3.9 miles |
| EPA rated range | 326 miles |
| Energy for a full charge | about 120.0 kWh at the wall |
Why 48 amps and not more
The onboard hardware takes 11.5 kW maximum. Pushing more current at the car does nothing. A 48 A supply refills the 120.0 kWh pack in 10.4 hours. You get 31 miles of range for every hour plugged in. The EPA test runs slightly slower at 29 miles per hour because test protocols account for grid conversion losses.
What the install involves
Hardwiring is mandatory for this load. No household receptacle handles 48 amps safely. Have a qualified electrician pull a circuit, land it on a 60 amp breaker, and verify your main panel has spare capacity. Copper wire gauge sizing matters here, so let a professional size the run properly.
Chargers that match this car
Energy monitoring built in. Hardwire it for the full 48 A.
Compact unit, good for tight garages.
Adjustable from 16 A to 50 A in the app, which helps if your panel is tight.

Common questions
- Can I plug this car into a standard wall outlet?
- Level 1 charging takes 83 hours for a complete fill. You get 3.9 miles of range per hour. It works in a pinch, but daily driving demands Level 2.
- What connector does the car use?
- The car uses a J1772 connection. This model year falls in the industry transition, meaning many vehicles ship with a NACS port but include a J1772 adapter. Confirm your port type before buying gear.
- Do I need a hardwired charger or a plug-in unit?
- You must hardwire a 48 A setup. Household outlets melt under continuous high loads. Hardwiring eliminates the failure point of a plug and socket.
- How does the EPA charge time differ from the max rate?
- The EPA rated cycle takes 11.2 hours instead of 10.4 hours. Federal testing accounts for thermal management overhead and efficiency losses during power conversion.
Other vehicles
Charging times derived from EPA data for the 2027 Cadillac Lyriq 11kW Charger (covering 2 EPA trim listings). Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
