How long does it take to charge a Subaru Solterra?

About 10h 45m from 10% to 100% on a typical 7.7 kW home Level 2 charger, or 44m at peak DC fast charging (150 kW). Level 1 (standard 120 V outlet) takes 50h 43m.

What is the max charging rate for a Subaru Solterra?

AC: 6.6 kW on-board limit. DC fast charging: 150 kW peak.

How Long to Charge a Subaru Solterra

Charging a Subaru Solterra (71 kWh battery) from 10% to 100% takes about 10h 45m on a typical 7.7 kW home Level 2 charger — or just 44m on a DC fast charger.

Level 1 (1.4 kW wall outlet)50h 43m

Level 2 home (7.7 kW)10h 45m

DC fast charge (150 kW peak)44m

All times above are for 10% → 100%. Subaru Solterra accepts up to 6.6 kW AC and 150 kW DC peak.

How we calculated this

The Subaru Solterra has a 71 kWh usable battery, an 6.6 kW on-board AC charger, and a 150 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%.

FAQ

Why is DC fast charge so much faster than Level 2?

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 Subaru Solterra, that’s 6.6 kW). DC fast chargers bypass the on-board charger and send DC current directly to the battery at up to 150 kW — about 22× faster.

Should I always charge to 100%?

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.

Is Level 1 charging useful?

Only if you drive less than ~40 miles/day. Level 1 adds about 4–5 miles of range per hour for the Subaru Solterra — enough for a short commute if you plug in every night, but inadequate for higher daily mileage.
