Why won't my Polestar 2 charge at home when DC fast charging still works?

Short answer: When a Polestar 2 will not AC charge at home but still DC fast charges, the onboard charger is the usual fault. Try another cable and charger first, reboot the car, then book Polestar Service if every AC source fails.

Symptom: Home charging error, stuck on Initializing, charge starts then stops, or only DC stations work.

What to check first

1. Try a different AC cable and a different home or public Level 2 charger.
2. Confirm DC fast charging still works.
3. Reboot the infotainment / try a soft reset.
4. Book Polestar Service and describe the AC-only failure.

Likely causes

1. Failing onboard charger (OBC). If every AC charger fails but DC fast charging works, the onboard charger that converts AC to DC is the usual suspect.
2. Charge cable, EVSE, or schedule glitch. Owners first try another cable, another home charger, and a reboot. If only one charger fails, fix that side first.
3. Software / TCAM quirks. Some charging errors clear after an infotainment reboot or software update. Persistent AC-only failure still needs diagnosis.

What it usually costs

Owners in these threads were still in diagnosis and did not post final OBC replacement prices.

Is it safe to keep driving?

Yes to drive if the high-voltage battery still has range. Plan charging around DC stations until AC works again.

DIY or shop?

Cable swaps and reboots are DIY. OBC replacement is a dealer job.

What owners report

• In 2022 P2 LRDM - Won't AC charge on Reddit r/Polestar, a 2022 Polestar 2 Long Range Dual Motor owner who mostly used a granny charger said home AC charging started failing after using a friend's 7 kW charger. Other owners described AC charging that starts, stops, and retries.
• In Onboard charger on way out? on Reddit r/Polestar, an owner of a six-week-old 2025 Polestar 2 said home charging stuck on Initializing and then errored, getting worse until it refused to charge. The owner suspected the onboard charger.
• In PS2 will not charge at home anymore on Reddit r/Polestar, a 2023 Polestar 2 owner said home charging stopped on two different AC chargers while Super/fast charging still worked, which matches an onboard charger fault pattern.

Quick tip

AC fails everywhere + DC works = think OBC. Do not keep buying new home chargers first.
