Polestar 5 Battery: Complete Guide
The Polestar 5 features an 112 kWh battery pack made by SK On. It uses high-nickel chemistry to store more energy and charge quickly. Its 800V system supports fast charging up to 350 kW. This allows the car to charge from 10% to 80% in about 22 minutes. You can also add 186 miles of range in just 10 minutes at a fast-charging station.
The Dual Motor version offers a range of 416 miles based on WLTP testing. The Performance version focuses on power, offering 874 hp and 351 miles of range. In 2026, the company will begin U.S. deliveries for this car. Starting at about $135,000, the Polestar 5 sits above the smaller Polestar 4 in the company’s lineup.
Polestar 5 Battery: Full Specs by Variant
| Variant | Battery (Usable) | Architecture | WLTP Range | System Power | 0–60 mph | Peak DC Rate |
|---|---|---|---|---|---|---|
| Dual Motor | 106 kWh NMC | 800V (PPA) | 416 miles | 738–748 hp | 3.8 sec | 350 kW |
| Performance | 106 kWh NMC | 800V (PPA) | 351 miles | 874–884 hp | 3.1 sec | 350 kW |
Polestar Performance Architecture: A Ground-Up Platform
The Polestar 5 uses a new Polestar Performance Architecture (PPA). Unlike the Polestar 4, this car does not share parts with Volvo or Geely. Engineers use hot-cured bonded aluminum to build the frame. This technique comes from making supercars. The frame is very stiff, which helps the car handle turns like a two-seat sports car. The battery pack acts as a support piece for the frame, which makes the car even stronger.
Polestar cares about the environment, so they use aluminum made with 83% renewable energy and 13% recycled material. The car is 5,087 mm long, which makes it bigger than a Porsche Taycan Sport Turismo. Even though it is large, the car weighs about 2,465 kg because of the lightweight aluminum. The 800V electrical system also helps reduce weight because it uses thinner and lighter cables than older 400V systems.
SK On Battery Cells: High-Nickel NMC
SK On supplies the Polestar 5 with high-nickel NMC battery cells. These cells contain over 90% nickel in the cathode chemistry. High-nickel NMC offers more energy density than standard versions. This design packs 106 kWh of usable energy into the PPA floor space.
High-nickel batteries have higher thermal sensitivity. To maintain cell stability, Polestar uses an 800V liquid thermal management system. SK On, South Korea’s third-largest battery maker, supplies these cells to Hyundai, Ford, and now Polestar.
350 kW Charging: 10 Minutes = 186 Miles
The Polestar 5’s 350 kW peak DC rate adds approximately 186 miles (300 km) in just 10 minutes under ideal conditions. The 10–80% charge on the Dual Motor completes in approximately 22 minutes. At a 350 kW-capable station with an 800V supply, this rate is fully realised — the PPA platform is specifically designed for this charging infrastructure. This charging performance directly competes with the Porsche Taycan’s 320 kW peak and the Genesis GV60’s 350 kW capability.
Polestar 5 Charging Speeds
| Method | Power | Polestar 5 (106 kWh usable) |
|---|---|---|
| Level 1 (120V) | ~1.4 kW | ~80 hours full |
| Level 2 (22 kW AC) | 22 kW | ~6 hours full |
| DC Fast (350 kW peak) | 350 kW | ~22 min (10–80%); 186 mi in 10 min |
Dual Motor vs Performance: Which Battery Suits You
Both variants use the same 106 kWh NMC 800V battery. The Performance model pulls more current, which raises power from 748 hp to 874 hp. This change cuts the 0–60 mph time from 3.8 seconds to 3.1 seconds.
The Performance boost costs 65 miles of WLTP range. The Dual Motor version gets 416 miles, while the Performance version gets 351 miles. The Dual Motor model remains the best choice for drivers who want a long-range electric GT. The Performance trim fits track-day drivers who want supercar speed in a four-door car.
Real-World Range Expectations
- Dual Motor, mild weather motorway: Approximately 340–380 miles — Electrifying.com’s full road trip returned approximately 350 miles at mixed speeds in European conditions
- Performance, aggressive driving: Approximately 270–310 miles when using full performance modes
- Cold weather: Approximately 300–340 miles for Dual Motor — 800V high-nickel NMC responds well to thermal management in cold conditions
- Efficiency comparison: The Polestar 5 Dual Motor achieves similar efficiency per kWh to the Porsche Taycan Sport Turismo — approximately 3.8–4.0 miles/kWh in mild mixed driving
Battery Warranty
Polestar covers the Polestar 5 battery with an 8-year or 160,000 km warranty. This is one of the best mileage limits for luxury electric cars. To use this warranty, the battery capacity must drop below 70% of its original level.
Under normal use, the high-nickel NMC (Nickel Manganese Cobalt) battery loses about 1.5% to 2.5% of its power each year. NMC is a type of battery material that stores a lot of energy.
You can use the 22 kW AC standard charger for easy daily charging. Using this charger helps the battery last longer because you can avoid using fast DC chargers every day.
Polestar 5 vs Competitors: Premium Electric GT Battery Comparison
Model | Battery (Usable) | WLTP Range | Peak DC Rate | Peak Power | Starting Price |
|---|---|---|---|---|---|
Polestar 5 Dual Motor | 106 kWh NMC 800V | 416 miles | 350 kW | 748 hp | ~$135,000 |
Porsche Taycan (2025) | ~97 kWh NMC 800V | ~424 miles WLTP | 320 kW | 402–938 hp | ~$99,000 |
Lucid Air Grand Touring | 118 kWh NMC 926V | ~516 miles EPA | 300 kW | ~819 hp | ~$138,000 |

Charging Tips for Polestar 5 Owners
- Set daily charge to 80%: High-nickel NMC particularly benefits from avoiding constant 100% — 80% of 106 kWh provides ~85 kWh covering 320+ miles of daily grand touring
- Use 22 kW AC at home: The standard 22 kW onboard AC charger fills from 20% to 100% in approximately 4 hours — ideal for overnight hotel stops on touring
- Plan 350 kW stops: The Polestar 5’s 186-miles-in-10-minutes capability is only fully realised at 350 kW stations — identify these via the Polestar app before long-distance routes
- Use Polestar app navigation for preconditioning: Routing to a DC charger activates the battery’s thermal system — critical for achieving the full 350 kW peak in any ambient temperature
Conclusion
The Polestar 5 features a 106 kWh high-nickel battery. This energy system uses SK On NMC chemistry built into a custom 800V aluminum platform. Buyers looking for a more accessible coupe-SUV should read the Polestar 4 battery guide.
The Dual Motor version offers a 416-mile WLTP range. It supports 350 kW fast charging and 22 kW home AC charging, which makes it a great road-trip vehicle.
At $135,000, the Polestar 5 competes in the premium EV GT market. Its Scandinavian design, bonded aluminum construction, and PPA platform engineering make it a strong alternative to the Porsche Taycan in 2026.
