What EV Charger Do You Need for a 2022 Porsche Taycan 4S Perf Battery?
Your home wall circuit can pump out massive power, but your car draws only what its onboard hardware allows. For this Porsche, the onboard charger stops accepting power at 48 amps. Buy a 48 amp Level 2 setup to match that ceiling. Anything larger wastes your money because the car cannot pull it.
The numbers
| Maximum AC charging rate | 11.0 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 9.0 hours |
| Range added per hour (Level 2) | about 25 miles |
| Full charge on a 120 V outlet | about 69 hours |
| Range added per hour (120 V) | about 3.3 miles |
| EPA rated range | 227 miles |
| Energy for a full charge | about 98.7 kWh at the wall |
Why 48 amps and not more
The onboard charger maxes out at 11.0 kilowatts, which demands 48 amps of continuous current. If you plug into a larger 50 amp or 80 amp supply, the car ignores the extra headroom and draws its maximum 48 amps anyway. Charging from empty takes 9.0 hours at this speed, adding 25 miles of range every hour. Buying a bigger charger buys you zero extra speed. Stick to the 48 amp target.
What the install involves
You need a dedicated 60 amp breaker to feed a 48 amp continuous load safely. A household wall receptacle cannot handle 48 amps, so your equipment must be hardwired directly. Have a licensed electrician check your main panel for spare capacity before buying parts. They will pull heavy gauge wire to the mounting spot, land it on the new breaker, and mount your unit.
Chargers that match this car
Energy monitoring built in. Hardwire it for the full 48 A.
Compact unit, good for tight garages.
Adjustable from 16 A to 50 A in the app, which helps if your panel is tight.

Common questions
- Can I use a standard wall outlet?
- No. Standard household receptacles max out at 15 or 20 amps and will melt under a continuous 48 amp load. You need a hardwired installation on a dedicated heavy circuit.
- What plug does this car use?
- Your car uses the J1772 connector for standard Level 2 AC charging. Every non-Tesla EV sold in North America through 2024 uses this exact plug type.
- How long does a full charge take?
- A full charge takes 9.0 hours when running at the maximum 48 amp rate. The EPA test estimates 10.5 hours because that testing protocol does not always run at the car's absolute peak AC rate.
- What happens if I plug into a Level 1 household outlet?
- You will get about 3.3 miles of range per hour. Recharging a completely dead battery this way takes 69 hours, which makes Level 1 impractical for daily driving.
Other vehicles
Charging times derived from EPA data for the 2022 Porsche Taycan 4S Perf Battery (covering 2 EPA trim listings). Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
