What EV Charger Do You Need for a 2023 Polestar 2?
You need a 48 amp Level 2 home charger to fill your Polestar 2 overnight. The onboard charger caps your AC intake at 11.0 kW. Going past 48 amps wastes money because the car cannot draw the extra juice.
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 7.7 hours |
| Range added per hour (Level 2) | about 35 miles |
| Full charge on a 120 V outlet | about 59 hours |
| Range added per hour (120 V) | about 4.6 miles |
| EPA rated range | 270 miles |
| Energy for a full charge | about 85.0 kWh at the wall |
Why 48 amps and not more
Matching the 48 amp limit pushes 35 miles of range into the battery every hour. A smaller 32 amp unit slows down the refill cycle without saving on hardware costs or installation friction. Hooking this car to a 50 or 60 amp EVSE changes nothing since the onboard hardware rejects anything past 48 amps. You get a full charge in 7.7 hours at peak rate. The EPA test logs 34 miles of range per hour over an 8.0 hour full charge cycle due to standard lab testing variables.
What the install involves
A 48 amp continuous load demands a 60 amp breaker paired with heavy gauge wiring. Local electrical codes forbid plugging a 48 amp unit into a wall outlet because standard receptacles melt under sustained high loads. Hardwiring the EVSE directly to the circuit breaker removes a point of thermal failure. Hire an electrician to pull the permit and run the line.

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.
- What plug does the car use?
- Your car uses a standard J1772 connector for all AC Level 2 charging sessions. Every non-Tesla EV sold in North America through 2024 uses this plug type.
- How long does a standard 120 volt wall plug take?
- Level 1 charging takes 59 hours to reach full capacity from empty. It pumps a mere 4.6 miles of range into the battery every hour.
- Will a 50 amp charger work?
- Yes, units like the ChargePoint Home Flex work fine, but your car limits the intake to 48 amps. You cannot pull the extra 2 amps.
Other vehicles
Charging times derived from EPA data for the 2023 Polestar 2 (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.
