TL;DR
71.4 kWh battery, 9-hour AC charge, 365 km range, 10-80% in 30 min (150kW DC) DC fast charging. Home charging covers 80–90% of all energy; fast charging covers the rest.
If you are bringing a Subaru Solterra home, you have 71.4 kWh to keep topped up and a 9-hour AC charge cycle to schedule around. That sounds intimidating until you map it to real life: 365 km is more than most weekly mileage, and an overnight plug-in covers it. Below is the full charging playbook for the Subaru Solterra.
Home charging the Subaru Solterra
Setting up the Subaru Solterra's home charge is a one-time job that shapes the next several years of ownership. The Subaru Solterra accepts standard AC at home and completes a full empty-to-full cycle in roughly 9 hours. For the typical owner, that translates to plugging in around 30% remaining at night and waking up to a full battery. Per-km charging cost on a standard residential tariff comes out far below an equivalent petrol car, and on off-peak time-of-use plans the gap widens further. Set the daily ceiling to 80% — that single discipline keeps the 71.4 kWh battery healthier for longer.
Fast charging the Subaru Solterra
Public fast-charging is where the Subaru Solterra's wider segment positioning becomes real-world relevant. The Subaru Solterra supports DC fast charging with a typical session profile of 10-80% in 30 min (150kW DC), which is what you'll use on road trips and the occasional bad-planning day. Plan long trips around natural stops — coffee, lunch, restroom — so the charge happens in parallel with something you'd do anyway. 365 km of range plus one DC stop is enough for almost any single-day journey within the country.
Subaru Solterra battery longevity
Battery health on the Subaru Solterra is largely about your daily routine, not big interventions. Avoid leaving the 71.4 kWh pack at very low or very high state of charge for long periods. Pre-condition before fast charging in cold weather — the battery accepts higher current when warm, which means a shorter session and less heat stress. Subaru's battery management system on the Subaru Solterra is conservative by design, so most owners who follow basic charging hygiene see minimal degradation over the first three to four years.
Practical next steps
Set the Subaru Solterra to schedule charging for off-peak tariff hours. Most utilities offer a night-rate window that cuts per-kWh cost meaningfully — the savings add up over a year.

Frequently asked questions
- Does the Subaru Solterra support DC fast charging?
- Yes — the Subaru Solterra supports DC fast charging with a typical session time of 10-80% in 30 min (150kW DC). That covers most road-trip needs in under a meal break.
- What's the per-km charging cost for the Subaru Solterra?
- At home on off-peak tariff, the Subaru Solterra costs a small fraction of an equivalent petrol car per km. Public fast charging is several times that — still cheaper than petrol on a typical session, but the gap narrows.
- What's the best daily charging routine for the Subaru Solterra?
- Plug in when you get home, set the cap to 80%, schedule the charge for off-peak hours, and forget about it. That single habit covers most Subaru Solterra owners' daily needs and is gentlest on the battery.
- How long does the Subaru Solterra take to charge fully?
- On a standard 7 kW AC wall box, the Subaru Solterra takes about 9 hours to go from empty to full — covering its full 71.4 kWh battery. Most owners plug in overnight at 30% remaining and wake up to a full charge.
The Subaru Solterra's charging spec is among the more accommodating in its segment — make use of that by setting up a home box on day one and keeping fast-charge sessions short.
