BYD ATTO 3 scheduled charging not starting: what to check

China-market owner report

In a discussion dated 2024-07-06, the linked China-market report raised this issue: An owner described a timer session not starting or dropping out around midnight; proposed workarounds in the post are not verified repairs. 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

1. 1Check the saved scheduleWhile parked, open Scheduled charging and verify the switch, start time and repeat cycle. Save any change rather than relying on a reminder shown during the last session.
2. 2Check the wallbox requirementsUse the wallbox instructions to confirm authentication and scheduling support. BYD limits this function to its slow AC equipment and warns that unsupported equipment can prevent charging.
3. 3Run a controlled immediate-charge checkIf you need energy now, select immediate charging when prompted. For subsequent sessions, disable scheduled charging in its settings rather than assuming this one-session override erased it.
4. 4Observe the startLook for charging information on the instrument display. Record the time, battery percentage, charger model and any message if the session does not begin.

Tick steps as you go. Your progress stays in this tab.

Check the result and know when to stop

If immediate charging works but a supported timer session fails, provide both sets of observations to the installer and BYD. Do not copy the forum suggestion to bypass wallbox authorisation or assume a midnight software fault applies to your export car.
