How to Access Battery Health Data via the Infotainment System

Polestar 2’s intuitive infotainment interface provides direct access to key battery metrics. Follow these steps:

• Open the central touchscreen and navigate to ‘Vehicle’ > ‘Battery’.
• Select ‘Battery Health’ to view state of charge, cycle count, and estimated range.
• The system also displays temperature trends and charge cycle efficiency—critical indicators often overlooked.
• Use the ‘Driving Insights’ tab to see real-time consumption patterns and charging habits.

This built-in dashboard gives you instant visibility, empowering daily checks without dealer visits.

Using Third-Party Apps and OBD2 Scanners for Deeper Analysis

For advanced users, a few approved OBD2 scanners and mobile apps deliver granular battery diagnostics. Tools like Polestar’s official app or third-party platforms such as Autel MaxiSYS support CAN bus data extraction, revealing:

• Cell voltage imbalances
• State of Charge (SoC) calibration accuracy
• Internal resistance trends

Pair these with Polestar’s firmware update notes to interpret data correctly—keeping your diagnostics current with 2025 standards. Always verify scanner compatibility and user reviews before purchasing.

Interpreting Key Battery Health Metrics

Understanding your battery’s status requires recognizing key indicators:

• State of Charge (SoC): Shows current charge level—aim for 20–80% for optimal longevity.
• Cycle Count: Tracks charge cycles; most batteries retain 80% capacity after 1,000–1,500 cycles.
• Endurance Capacity: Polestar’s battery health reports indicate capacity fade, usually 2–5% annually under normal use.
• Temperature Range: Extreme heat or cold accelerates degradation—monitor climate controls.

These metrics, combined, offer a clear picture of your battery’s condition and when maintenance or service might be needed.

Practical Tips to Maintain Battery Health Long-Term

Beyond monitoring, proactive care ensures lasting performance:

• Avoid full discharges; top off charges between 20–80%.
• Charge slowly when possible—fast charging increases heat and stress.
• Keep battery temperature between 15°C and 35°C for best efficiency.
• Update firmware regularly to benefit from improved battery algorithms.

Following these habits aligns with Polestar’s 2025 reliability focus and enhances your vehicle’s resale value.

Conclusion

Checking your Polestar 2 battery health doesn’t have to be complex. With built-in infotainment tools and select third-party scanners, you gain clear insights to protect your investment. Stay informed, act early on warning signs, and maintain habits that preserve range and performance. Take control of your battery today—your Polestar will thank you.
