What EV Charger Do You Need for a 2027 Cadillac Lyriq V Series 19kW Charger?
Eighty amperes. That is the peak AC draw for your battery pack. You need a Level 2 setup capable of delivering that exact output to hit the full charge time of 6.3 hours. Plug into a standard household socket and you wait 84 hours instead.

Why 80 amps and not more
Your car accepts up to 19.2 kilowatts through the onboard charger. Lesser units throttle your intake and leave you sitting on the charger longer. Feeding this vehicle anything less than 80 amps leaves onboard capacity on the table. A lesser 48 amp or 50 amp unit still works fine if you charge overnight, but it will not run at the maximum possible speed. Buy the 80 amp gear if you want the absolute fastest turnaround at home.
What the install involves
This requires hardwiring only. There is no plug to stick in the wall. You need an electrician to pull a 100 amp circuit and land it on the breaker. Ask them to verify your main panel has spare physical and electrical capacity before buying parts. Code demands a hardwired connection for continuous loads this high.
Chargers that match this car
The first unit matches your car's full 80 A. The others are slightly slower but cost less.
One of the few home units that can feed an 80 A car. Needs a 100 A circuit.
Adjustable from 16 A to 50 A in the app, which helps if your panel is tight.
Energy monitoring built in. Hardwire it for the full 48 A.

Common questions
- Can I use a regular wall outlet?
- Level 1 charging on a standard 120 volt outlet takes 84 hours for a full fill. That yields 3.4 miles of range per hour. You need a dedicated Level 2 circuit for normal daily driving.
- What connector does this car use?
- It uses a J1772 connection. This model year falls in the industry transition. Many vehicles ship with a NACS port but include a J1772 adapter, so a J1772 home charger still works. Confirm your car port before buying.
- Why does the EPA charge time differ?
- The EPA rated charge time is 7.0 hours at 41 miles per hour. The EPA test does not always run at the car peak AC rate. Real world charging at the full 80 amp rate reaches 45 miles per hour and finishes in 6.3 hours.
- Do I need a permit for the installation?
- Most local building codes require a permit for a 100 amp circuit installation. Check with your city or county building department. Your electrician usually handles this paperwork.
