How Long to Charge a Polestar 2
Charging a Polestar 2 (78 kWh battery) from 10% to 100% takes about 10h 08m on a typical 7.7 kW home Level 2 charger — or just 35m on a DC fast charger. All times above are for 10% → 100%. Polestar 2 accepts up to 11 kW AC and 205 kW DC peak. The Polestar 2 has a 78 kWh usable battery, an 11 kW on-board AC charger, and a 205 kW peak DC charging rate. For AC charging (Level 1 and Level 2), actual rate is the lesser of the charger’s output and the car’s on-board AC limit. We assume ~10% loss between AC input and the battery. For DC fast charging, real-world rate tapers above ~80% state of charge to protect the battery. We model 0–80% at 80% of peak rate, and 80–100% at 30% of peak — consistent with published curves from Tesla, Hyundai/Kia, Ford, and Rivian. This is why "0 to 80%" is the marketing number for DCFC: filling the last 20% takes nearly as long as the first 80%. Level 2 home charging uses your home’s 240 V circuit, capped at 11.5 kW (and at the car’s on-board AC charger — for the Polestar 2, that’s 11 kW). DC fast chargers bypass the on-board charger and send DC current directly to the battery at up to 205 kW — about 18× faster. For lithium iron phosphate (LFP) batteries, yes. For nickel-based chemistries (most non-LFP EVs), keeping the daily charge limit at 80–90% extends battery life noticeably. Only charge to 100% before long trips. Only if you drive less than ~40 miles/day. Level 1 adds about 4–5 miles of range per hour for the Polestar 2 — enough for a short commute if you plug in every night, but inadequate for higher daily mileage.Detailed charging scenarios
