OWNER ANSWER
SEALION 7 charging cable will not release
For a stuck charging plug on your SEALION 7, end the session, unlock the car and remove the plug promptly while supporting its body. After DC charging, the handbook specifies two unlock presses within three seconds.
- End the charging session using the charger’s normal stop control.
- Confirm the charger has stopped delivering power. Safety note: A locked plug must not be forced out: this can damage the connector. For unusual heat, damage, smoke, arcing or liquid inside the connection, keep clear and get operator or emergency help rather than attempting a manual release.
- Unlock the car; after DC charging, press unlock twice within three seconds.
- Support the plug body and remove it gently within the unlocking window.
- If it has relocked, unlock again and make one gentle attempt.
Why it locks again
SURF and original SEAL specify a 30-second removal window. SEALION 7 also relocks after a short time. A paused smart session or a full battery is not the same as confirming the charger session has ended.
Emergency release on SEALION 7
Once charging has definitely stopped, use the handbook illustration to identify the cap in the right side panel inside the boot. Open that cap, pull the charging-lock cable and remove the plug, then refit the cap. A recurring lock failure needs BYD inspection.
If that did not work
If the operator cannot end a public session, use its support number with the post ID. If the session is stopped but normal unlocking still fails, ask BYD about the charging lock for your exact car; use the documented emergency release only when its cable is positively identified.
What to note down for support: AC or DC, charger ID, its stopped status, the car message and the result of the timed unlock help support choose the right release.
