What EV Charger Do You Need for a 2026 Cadillac Optiq V Series 19 kW charger?
Wiring a 100 A circuit for your car demands a professional electrician to pull heavy copper and land it on a dedicated breaker in your panel. You need an 80 A Level 2 home charger to match the onboard hardware of the Cadillac Optiq V Series 19 kW charger. This setup delivers 47 miles of range per hour. A full battery takes 5.3 hours.
The numbers
| Maximum AC charging rate | 19.2 kW (80 A) |
|---|---|
| Charger size to buy | 80 A |
| Circuit breaker required | 100 A |
| Outlet / connection | hardwired only |
| Charge port | J1772 |
| Full charge on Level 2 | about 5.3 hours |
| Range added per hour (Level 2) | about 47 miles |
| Full charge on a 120 V outlet | about 71 hours |
| Range added per hour (120 V) | about 3.5 miles |
| EPA rated range | 250 miles |
| Energy for a full charge | about 102.5 kWh at the wall |
Why 80 amps and not more
Your car accepts up to 80 amps through its on board charger. Feeding it anything less slows down the replenishment rate. A lesser unit drops your charging speed because the vehicle can draw 19.2 kilowatts. Sticking with an 80 amp EVSE means you refuel the 102.5 kWh battery overnight without hassle. The EPA test logs a slightly slower 5.9 hours at 42 miles per hour because standard testing protocols vary from peak output rates.
What the install involves
Plugs are out of the question because this configuration requires hardwiring only. An electrician must verify your main panel has spare capacity for a 100 A breaker before running heavy gauge wire to the garage wall. Never attempt this high voltage work yourself. Once the hardware is bolted down and the breaker is flipped, the unit connects directly to your car via a J1772 connector.
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 standard wall outlet?
- No. Level 1 charging on a standard 120 volt outlet yields only 3.5 miles per hour and takes 71 hours to fill the battery.
- What connector does this car use?
- It uses a J1772 connector. Many 2025 and newer vehicles ship with a NACS port but include a J1772 adapter, so a J1772 home charger still works.
- Will a 50 amp charger work instead?
- Yes, but it will charge slower than the maximum 80 amp rate your car supports. Your vehicle manages the incoming power automatically.
- Do I need an adapter for Tesla stations?
- An adapter like the Lectron Tesla to J1772 Charging Adapter 80A lets a J1772 car use Tesla Destination Chargers and Wall Connectors.
Other vehicles
Charging times derived from EPA data for the 2026 Cadillac Optiq V Series 19 kW charger. Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
