How to stop DC charging and unlock a BYD ATTO 3 cable
Stopping the charger and releasing its connector are separate actions. Follow the documented release sequence before treating a firmly held plug as a broken port.
Applies to the official ATTO 3 (2024), English RHD, 20260304 handbook. Chinese domestic Yuan Plus (元PLUS) reports supplied the question; they do not verify an export-car defect, shared firmware or a repair. Match your car's handbook before using a control.
End the session using the charging operator’s app or card control. BYD also documents pressing unlock twice within three seconds to stop DC charging and release the charge port.
China-market owner report
In a discussion dated 2025-12-10, the linked China-market report raised this issue: A new Yuan Plus owner asked how to stop charging and whether a percentage target could be set. This is an individual account, not a confirmed diagnosis or failure-rate finding. The steps below use the export handbook.
Checks to make while safely parked
Tick steps as you go. Your progress stays in this tab.
Check the result and know when to stop
If the connector remains locked, stop pulling and contact the charging operator first. The manual describes an emergency vehicle release, but a different charger-side lock can still require operator assistance. Smoke, abnormal heat or damaged equipment requires immediate help, not repeated unlock tests.
Common questions
Can I pull the connector to stop charging?+
Use the documented stop and unlock controls first. A locked connector is not an invitation to use more force.
Is the AC release identical?+
No. The manual gives separate AC and DC stopping instructions; the DC double-unlock timing matters here.
