Your Polestar 2 won't charge at home and you need to get to work tomorrow. Don't panic—most charging issues are fixable in under 30 minutes with no tools required.
This guide covers the most common Polestar 2 charging problems UK owners face and how to fix them fast.
Quick Diagnosis (3 Minutes - Try This First)
- Check charge port light (30 seconds) - Should pulse amber when plugged in
- Inspect cable connections (1 minute) - Both ends seated firmly?
- Check car is unlocked (30 seconds) - Locked Polestar won't accept charge
↳ Most Common Cause: 12V battery depletion (38% of UK cases)
Fix 1: 12V Battery Depletion (38% of Cases)
Why This First: The Polestar 2 uses its 12V battery to activate the high-voltage contactors needed for charging. If the 12V battery is low, charging won't start even with a full main battery.
Symptoms:
- Charge port light doesn't illuminate
- Car feels "dead" when approaching
- App shows car as "asleep" or offline
- Central display slow to wake
How to Fix:
- Open the front boot (frunk) - Pull the interior release or use the app
- Locate the 12V battery - It's under the floor panel on the right side
- Check battery voltage - Should be 12.4V+ (use a multimeter if available)
- Jump start if needed - Connect jump leads to 12V terminals
- Leave connected for 10 minutes - Let the 12V charge
- Try charging again - Should work immediately
Time: 15-20 minutes Cost: £0 (or £60-£80 for replacement 12V battery) Success Rate: 85%
If This Doesn't Work: The 12V battery may need replacing (£120-£180 at Polestar service, £60-£80 DIY).
Fix 2: Charge Port Lid Not Fully Open (22% of Cases)
Why This Second: Polestar 2's motorised charge port lid has a sensor. If it doesn't register as fully open, the car won't accept a charge.
Symptoms:
- Charge port light flashes then stops
- Hear motor whirring but lid barely moves
- Error message about charge port
- Cold weather makes it worse
How to Fix:
- Press charge port button firmly - Hold for 3 seconds
- Listen for motor - Should whir and lid should pop open fully
- Check for debris - Ice, leaves, or dirt can jam the mechanism
- Manually assist if stuck - Gently pull lid open while pressing button
- Clean the hinge - Use WD-40 or similar on pivot points
- Try charging - Plug in when lid is fully open
Time: 5-10 minutes Cost: £0 Success Rate: 90%
If This Doesn't Work: The lid motor or sensor may need replacement (£150-£300 at Polestar service).
Fix 3: Software Glitch / Infotainment Freeze (18% of Cases)
Why This Third: Polestar 2 runs Android Automotive OS. Like any software, it can freeze or glitch, preventing charging commands from processing.
Symptoms:
- Centre screen frozen or unresponsive
- Charging scheduled but doesn't start
- App shows connected but not charging
- Recent software update installed
How to Fix:
Soft Reset (Try First):
- Press and hold the home button - Centre of steering wheel
- Wait 30 seconds - Screen will go black
- Release and wait - System reboots (2-3 minutes)
- Try charging - Plug in after reboot completes
Hard Reset (If Soft Doesn't Work):
- Turn off car completely - Press brake, hold start button
- Exit and lock car - Wait 5 minutes
- Unlock and enter - Press brake, start car
- Check for updates - Settings > System > Updates
- Try charging - After updates install
Time: 5-15 minutes Cost: £0 Success Rate: 75%
If This Doesn't Work: Factory reset may be needed (backs up your settings first).
Fix 4: Scheduled Charging Confusion (12% of Cases)
Why This Fourth: Polestar's scheduled charging is controlled both in-car and via the app. Conflicting settings cause charging to not start.
Symptoms:
- Plug in but charging doesn't start immediately
- App shows "Scheduled" status
- Car is ready at wrong time
- Works at public chargers but not home
How to Fix:
- Open Polestar app - Go to Climate & Charging
- Check scheduled charging - Toggle OFF temporarily
- Check departure times - Ensure correct time zone
- Verify location - Home location must be set correctly
- Disable Octopus integration - If using, check settings
- Try immediate charge - Should start within 30 seconds
In-Car Settings:
- Centre screen > Charging
- Scheduled charging > OFF
- Plug in > Should charge immediately
Time: 5 minutes Cost: £0 Success Rate: 95%
If This Doesn't Work: Delete and reinstall the Polestar app.
Fix 5: Home Charger Compatibility (8% of Cases)
Why This Fifth: Some UK home chargers have known issues with Polestar 2, particularly around earth fault detection.
Symptoms:
- Works at public chargers, not home charger
- Charger shows error code
- Charging starts then stops after seconds
- RCD trips when plugging in
Known UK Charger Issues:
| Charger | Issue | Solution |
|---|---|---|
| Rolec | Earth fault sensitivity | Firmware update |
| Pod Point Solo (old) | Communication timeout | Contact Pod Point |
| Some Hypervolt | CP signal issues | Firmware update |
| Cheap imports | Various | Replace with quality charger |
How to Fix:
- Check charger firmware - Update via manufacturer app
- Test with granny cable - 3-pin cable works? Charger issue
- Contact charger manufacturer - Many have Polestar-specific fixes
- Check earthing - May need electrician (£80-£150 callout)
- Try different charger - Borrow neighbour's cable to test
Time: 30 minutes to investigate Cost: £0-£150 (if electrician needed) Success Rate: 80%
If This Doesn't Work: Some chargers simply aren't compatible—Ohme and Wallbox work reliably with Polestar.
Fix 6: Onboard Charger Fault (2% of Cases)
Why This Last: Actual hardware faults are rare but do occur. The Polestar 2's onboard charger (OBC) handles AC charging.
Symptoms:
- Never charges on AC (home charger or public AC)
- DC rapid charging works fine
- Error codes mentioning "OBC" or "charger"
- Problem persists after all other fixes
Warning Signs:
- ⚠️ Burning smell when charging attempts

Real UK Owner Experience
Owner: PolestarDave, SpeakEV Forum, February 2025
"My Polestar 2 Long Range suddenly stopped charging at home. Tried everything—different cables, reset the car, nothing worked. Turns out the 12V battery had dropped to 11.8V after I left it parked for two weeks over Christmas. A 20-minute jump start from the wife's car and it's been fine since. Now I make sure to drive it at least weekly."
Outcome: DIY fix (12V jump), £0 cost, 20 minutes
Owner: EV_Sophie, Reddit r/Polestar, January 2025
"Charging was completely random—sometimes worked, sometimes didn't. After three service visits, a software update finally fixed it. Polestar pushed a specific update for cars built in 2023 that had a charging timeout bug. If you're having intermittent issues, check you're on the latest software version."
Outcome: Software update, £0 cost, automatic OTA
Frequently Asked Questions
Why does my Polestar 2 stop charging at 80%?
This is normal and intentional. The default charge limit is 80% to preserve battery longevity. To charge to 100%, go to Centre screen > Charging > Charge limit > Move slider to 100%. Only charge to 100% when you need the extra range.
Can I use a Tesla charger with my Polestar 2?
Yes, with an adapter. Tesla Destination chargers (not Superchargers) use Type 2 connectors and work with Polestar 2. Tesla Superchargers in the UK are now open to non-Tesla vehicles—you'll need the Tesla app to start a session.
Why does my Polestar 2 charge slower at home than advertised?
The Polestar 2 Long Range can accept 11kW AC, but most UK home chargers deliver 7kW (single-phase limit). This is normal. 7kW adds approximately 25 miles of range per hour, enough to fully charge overnight.
My Polestar 2 shows "Charging Interrupted"—what does this mean?
This usually means the power supply was interrupted. Common causes: smart tariff switching (normal with Octopus Intelligent), RCD trip, or power cut. Check your consumer unit and retry. If persistent, have an electrician check your installation.
Does cold weather affect Polestar 2 charging?
Yes. Below 5°C, charging is slower as the battery preheats before accepting charge. The charge port lid may also be stiff. Pre-conditioning via the app before charging helps—it warms the battery and makes charging faster.
How do I know if my Polestar 2's 12V battery needs replacing?
Symptoms include: slow wake-up, app connectivity issues, warning messages about low voltage, and failed charge attempts after the car has been parked for several days. A healthy 12V battery should read 12.4-12.8V. Below 12.2V indicates replacement needed.
