What EV Charger Do You Need for a 2026 Cadillac Optiq V Series 11 kW Charger?
A 60 amp circuit feeds the wall, but your car caps the intake at 48 amps. Buying gear that pushes past that limit wastes money. Match the gear to the vehicle limit instead. You need a 48 amp Level 2 setup.
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 8.9 hours |
| Range added per hour (Level 2) | about 31 miles |
| Full charge on a 120 V outlet | about 71 hours |
| Range added per hour (120 V) | about 3.9 miles |
| EPA rated range | 278 miles |
| Energy for a full charge | about 101.9 kWh at the wall |
Why 48 amps and not more
Your car accepts a maximum of 48 amps, drawing 11.5 kW of power. Buying a larger charging unit changes nothing because the onboard charger limits intake. Pushing more current past 48 amps does not speed up the 8.9 hour charge time for the 101.9 kWh battery. Stick to the 48 amp limit. It pumps 31 miles of range into the battery every hour.
What the install involves
A 48 amp supply requires a dedicated 60 amp breaker. No household receptacle handles that load, so you must hardwire the unit directly. Call a licensed electrician to pull the heavy copper wire, land it on the breaker, and check your service panel for spare capacity. Do not attempt this hookup yourself.
Chargers that match this car

Common questions
- How long does a full charge take?
- A full charge takes 8.9 hours using Level 2 equipment at maximum speed. Standard household Level 1 charging takes 71 hours.
- What plug does the charger use?
- This setup uses hardwiring because a 48 amp EVSE exceeds household receptacle limits. No wall plug is involved.
- What kind of connector does the car have?
- The car uses a J1772 connector. Confirm your specific port before buying gear, as this model year falls in the transition to NACS.
- What is the EPA charge time?
- The EPA test estimates a full charge takes 9.5 hours at 29 miles per hour. That test does not always run at the car's absolute peak AC rate.
