48 amp vs 80 amp charger for a Cadillac LYRIQ
For the trims below, EPA data shows the car accepts more than a 48 A charger delivers (11.52 kW). A 80 A charger (19.2 kW) saves up to about 4.2 hours on an empty-to-full charge (estimate). It needs a 100 A breaker instead of 60 A.
Per trim
| Trim | Empty→full at 48 A | Empty→full at 80 A | Miles per 8 h at 48 A | Miles per 8 h at 80 A | Why we think it accepts more |
|---|---|---|---|---|---|
| 2027 LYRIQ 19kW Charger | 10.4 h | 6.3 h | 250 mi | 413 mi | EPA trim name states a 19 kW onboard charger |
| 2026 LYRIQ (19 kW Charger) | 10.4 h | 6.3 h | 250 mi | 413 mi | EPA trim name states a 19 kW onboard charger |
| 2027 LYRIQ AWD 19kW Charger | 10.4 h | 6.3 h | 232 mi | 383 mi | EPA trim name states a 19 kW onboard charger |
| 2026 LYRIQ AWD | 10.4 h | 6.3–7.0 h | 232 mi | 387 mi (max) | EPA 240 V time implies an average of 17.2 kW, so it must accept more than 11.52 kW at times |
| 2027 LYRIQ AWD V SERIES 19kW Charger | 10.5 h | 6.4 h | 217 mi | 358 mi | EPA trim name states a 19 kW onboard charger |
| 2026 LYRIQ PAWD V SERIES (19 kW Charger) | 10.5 h | 6.4 h | 217 mi | 358 mi | EPA trim name states a 19 kW onboard charger |
Estimates: energy for the full EPA range (kWh/100 mi × range ÷ 100, at the wall) ÷ charging power. Where EPA states the onboard charger we cap at it. Otherwise the 80 A figure is a range: from full 19.2 kW down to the average power implied by EPA's 240 V time, because the true onboard limit isn't in EPA data. Real charging tapers near 100%. Vehicle data: fueleconomy.gov.
For the other 6 trim(s) EPA data doesn't show more than 11.52 kW being accepted, so an 80 A charger may not help them: 2027 LYRIQ 11kW Charger, 2026 LYRIQ (11 kW Charger), 2027 LYRIQ AWD 11kW Charger, 2026 LYRIQ PAWD, 2027 LYRIQ AWD V SERIES 11kW Charger, 2026 LYRIQ PAWD V SERIES (11 kW Charger).
Does it matter day to day?
Most drivers plug in overnight and rarely charge from empty. Both chargers add 250+ miles in 8 hours for the most efficient qualifying trim. The 80 A option mainly helps with long daily drives, short charging windows on time-of-use plans, or sharing one charger between two cars. The bigger circuit can cost more to install (wire size, panel capacity), and that cost isn't in our data.
