How to schedule overnight AC charging on an XPENG G9

Scheduled AC charging can move a home session into your tariff’s cheaper hours. It also means a plugged-in G9 may wait intentionally rather than begin charging immediately.

Checked on 27 October 2026 against XPENG’s 2025 English G9 manual for XOS V5.6.0, printed pages 294–295. Chinese-market owner reports identify the question; they do not establish a common defect, a guaranteed fix, or matching export equipment. Stop if your car’s controls differ.

THE QUICK ANSWER

Open Settings → Charging and Discharging → Charging, enable Slow Charging Appointment and set the charging time. Connect the AC cable, lock the vehicle and confirm that the session starts at the intended time.

Before you start

Check your actual electricity tariff, intended charge limit and the energy needed for the next journey. Use a correctly installed compatible charger. Review any wallbox scheduling too, because a charger that does not supply power can prevent the car’s selected window from working.

Set and observe the charging window

1Review the charge targetCheck the selected charge limit and allow enough charging time. A cheap-rate window may be shorter than the time needed to reach a high target.
2Open the schedule controlOn the G9 display, open Settings → Charging and Discharging → Charging and locate Slow Charging Appointment.
3Set the intended timeEnable the feature and save the charging time shown by your matching software. Recheck the saved window and any repeating-day choices offered by the car.
4Connect, lock and verifyConnect the AC cable normally and lock the vehicle as directed in the manual. Check the charging indication at the scheduled start and the battery percentage afterwards.

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

Check the result

Compare the actual session with the target and window. If nothing started, collect the car’s schedule, wallbox availability and any error message. A missed schedule and an interrupted charging session are different problems and need different evidence.
