Charging a Cadillac Lyriq at Home

The Lyriq's 11.5 kW onboard charger and big battery make a 48-amp unit worthwhile — here's the setup, through GM's move to NACS.

The Cadillac Lyriq's onboard charger accepts up to 11.5 kWof AC (some cars are optioned with a 19.2 kW charger), and its battery is large — so a 48-amp Level 2 charger earns its keepby shortening the overnight fill. Home charging is standard AC; the connector is what changes across GM's move to NACS.

The Lyriq is a big, heavy luxury SUV with a battery to match, which is exactly the case where a faster home charger pays off — more amps means more range added per overnight hour. GM's connector transition is the detail to get right.

The connector: CCS1 through 2026, NACS from 2027

2023–2026 Lyriqs use a CCS1 inlet, which accepts a J1772 Level 2 connector natively — any standard J1772 home charger works, no adapter. The 2027 Lyriq moves to a native NACS port. A NACS-port Lyriq charges at home with a NACS home charger or a J1772 charger plus a J1772-to-NACS adapter. Confirm your inlet before buying hardware.

What amperage to buy

The Lyriq's standard 11.5 kW onboard charger pairs perfectly with a 48-amp charger, which needs a 60-amp circuit — check your panel with the wire size and breaker guide. Cars optioned with the 19.2 kW charger can go faster still, but that requires an 80-amp circuit and is overkill for most homes. A 40-amp unit like the Emporia Level 2 still fills the Lyriq overnight if 60 amps is not available.

Hardwire for the full speed

A plug-in charger on a NEMA 14-50 outlet caps at 40 amps; hardwiring unlocks 48. For a large-battery Lyriq kept long-term, hardwiring a 48-amp unit is the usual choice for the extra overnight range. The circuit and receptacle are a licensed-electrician job.

Questions

Frequently asked

What amp charger is best for a Cadillac Lyriq?
A 48-amp charger suits the Lyriq's 11.5 kW onboard charger and large battery, adding range fastest overnight. It needs a 60-amp circuit. If your panel can't supply that, a 40-amp unit still fills the SUV overnight for normal driving.
Does my Lyriq have a J1772 or NACS port?
2023–2026 Lyriqs use CCS1, which takes a J1772 charger natively at home. The 2027 Lyriq switches to a native NACS port, which needs a NACS charger or a J1772-to-NACS adapter. Check your charge inlet.
Is the 19.2 kW charger option worth it?
For most owners, no. The 19.2 kW onboard charger needs an 80-amp circuit few homes have to spare, and the standard 11.5 kW charger on a 48-amp unit already refills the Lyriq overnight. It mainly benefits high-mileage drivers with the electrical capacity for it.
Can a Cadillac Lyriq use a Tesla Supercharger?
Yes — a 2027 NACS-port Lyriq natively, and an earlier CCS1 Lyriq with a NACS-to-CCS DC adapter. That is DC road-trip charging, separate from the AC charger you use at home.
