What EV Charger Do You Need for a 2025 Cadillac Lyriq?
A full charge takes 10.2 hours on a Level 2 setup. That timeline easily fits into a standard overnight window. You need a 48 amp EVSE to hit that speed. Anything slower leaves range on the table.
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 10.2 hours |
| Range added per hour (Level 2) | about 32 miles |
| Full charge on a 120 V outlet | about 82 hours |
| Range added per hour (120 V) | about 4.0 miles |
| EPA rated range | 326 miles |
| Energy for a full charge | about 117.4 kWh at the wall |
Why 48 amps and not more
Your car accepts a maximum of 48 amps through its onboard charger at 11.5 kilowatts. Buying a bigger 80 amp unit wastes money because the vehicle cannot draw the extra juice. A 48 amp supply puts 32 miles of range into the battery every hour. Dropping to a smaller breaker means slower overnight recovery times. Match the equipment to the maximum onboard limit for peak performance.
What the install involves
A 48 amp charger requires a 60 amp breaker to handle continuous loads safely. Hardwiring is mandatory here because no standard household receptacle is rated for 48 amps. Call a licensed electrician to pull the wire and land it on the main panel. Have them check if your current electrical service has spare capacity for the heavy load.

Common questions
- Can I use a normal wall outlet?
- Level 1 charging from a standard household outlet gives you 4.0 miles per hour. That takes 82 hours for a full fill, which is too slow for daily driving. You need a dedicated Level 2 circuit.
- What connector does the car use?
- It uses a J1772 connector. This model year falls in the industry transition to NACS ports, so check your specific car before buying hardware. An adapter handles older or alternate stations if needed.
- Why does the EPA charge time differ?
- The EPA rates a full charge at 11.2 hours, yielding 29 miles of range per hour. Real world results hit 10.2 hours because testing protocols vary. Both numbers show practical overnight feasibility.
- Do I need a permit for the install?
- Most local jurisdictions require a permit for high voltage electrical work. Your electrician should pull this paperwork before starting the job. Inspections keep your home insurance valid.
Other vehicles
Charging times derived from EPA data for the 2025 Cadillac Lyriq (covering 3 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.
