Subaru Solterra Charging Instruction: Best Methods, Costs, and Charging Time
The 2025 Subaru Solterra is Subaru’s flagship electric SUV, designed for both urban commuting and outdoor adventures. Built on the e-TNGA platform co-developed with Toyota, it features standard all-wheel drive (AWD) and an EPA-estimated range of up to 227 miles. However, charging speed is a key consideration—with 6.6 kW AC charging and 100 kW DC fast charging, the Solterra lags behind some competitors in charging efficiency.
Understanding how to charge Subaru Solterra effectively ensures optimal performance, convenience, and cost savings.
Subaru Solterra Charging Specifications
The 2025 Subaru Solterra is available in multiple trims, all featuring the same battery size and charging capability:
- Battery Capacity: 72.8 kWh
- Charging Port Type: CCS1 (Combined Charging System)
- Maximum Charging Power:
- AC (Level 1 & Level 2): 6.6 kW
- DC Fast Charging: 100 kW
- EPA Estimated Range:
- Premium Trim: 227 miles
- Limited, Touring & Touring Onyx Edition: 222 miles
Subaru Solterra charging connector
The Subaru Solterra uses the J1772 connector for Level 1 and Level 2 AC charging and the CCS1 connector for DC fast charging. If you plan to charge your Solterra at a Tesla Supercharger, you’ll need a NACS to CCS1 adapter.
Subaru Solterra Charging Time by Charger Type
Charge time varies based on vehicle level of charge, charging rate, vehicle’s electric consumption ratio,ambient temperature and many other factors. The following data is based on ideal conditions and should be used for reference only. Real-world results may vary.
Level 1 Charging (120V Home Outlet)
Using a standard 120V home outlet, Level 1 charging is the slowest method, best used for emergency or overnight charging.
- Charging Speed: 4.5 – 4.7 miles of range per hour
- Charge Time (10%-80%): ~34.1 hours
- Charge Time (0%-100%): 40+ hours
- Time to Add 30 Miles of Range: 6-7 hours
Level 2 Charging (240V Home & Public Chargers)
Level 2 charging is the best daily home charging solution, significantly reducing charge times.
- Charging Power: 3.8 kW – 6.6 kW
- Charging Speed: 11.1 – 19.6 miles of range per hour
- Charge Time (10%-80%): 8 – 14 hours
- Charge Time (0%-100%): 10 – 17 hours
A 32A Level 2 home charger is recommended, as higher power chargers (40A, 48A, etc.) won’t improve charging speed due to the Solterra’s 6.6 kW AC charging limit.
DC Fast Charging (100 kW Public Chargers)
DC fast charging is ideal for road trips, allowing rapid power replenishment.
- Charging Speed: Adds ~3.7 miles per minute
- Charge Time (10%-80%): ~43.7 minutes
- Time to Add 30 Miles of Range: ~8 minutes
While the Solterra can plug into 150 kW+ chargers, its maximum DC charging speed is 100 kW, meaning higher-powered stations won’t improve charge time.
Choosing the Best Home Charger for Subaru Solterra Charging
For an efficient home charging setup, consider these factors:
- Power Output: The Solterra supports up to 6.6 kW AC charging, so a 32A Level 2 charger is the best choice.
- Installation Costs: A 32A charger is cost-effective and provides overnight charging without major electrical upgrades.
- Hardwired vs. Plug-In Chargers: Hardwired chargers are more stable and reliable for long-term use.
- Smart Charging Features: Many Level 2 chargers include Wi-Fi connectivity, allowing users to schedule charging sessions and track usage.
Subaru Solterra Charging Costs
Electricity costs vary significantly across U.S. regions. You can view updated residential and commercial electricity rates on the EIA website, which may help estimate your actual charging expenses.
Home Charging Costs
Charging at home is the most affordable option. Based on an average electricity rate of $0.162 per kWh:
- Cost per 100 miles: $5.34 – $5.47
- Full Charge Cost (72.8 kWh battery): $11.81
Public DC Fast Charging Costs
Fast charging is more expensive but useful for road trips. Based on an average commercial rate of $0.350 per kWh:
- Cost per 100 miles: $11.54 – $11.81
- Full Charge Cost: $25.48
Can the Subaru Solterra Charge at Tesla Superchargers?
Currently, the Subaru Solterra cannot charge at most Tesla Superchargers. The only exception is Tesla Superchargers equipped with Magic Dock, which feature a built-in CCS1 adapter.
- Magic Dock Superchargers: If available, allow Subaru Solterra to charge at Tesla stations.
- Future Compatibility: Subaru has not announced plans to support Tesla Superchargers.
- Best Alternative: Electrify America, EVgo, and other CCS networks offer fast-charging options.
To locate Magic Dock-enabled Tesla Superchargers, check the Tesla app or Supercharger map.
Conclusion
The 2025 Subaru Solterra is a solid all-wheel-drive electric SUV, but its slow charging speeds may be a drawback for some users. While daily home charging with a Level 2 charger is practical, long-distance travel requires careful charging stop planning due to its slower DC charging speeds.
For Subaru Solterra owners, investing in a Level 2 home charger and planning fast-charging stops along CCS networks will ensure efficient charging and worry-free driving.
