XPENG G6 Scheduled Charging and Charge Limit: Step-by-Step UK Guide

On the earlier UK G6, open Charging and Discharging → Charging to set the slow-charging schedule and charge limit. If the car is controlling the start time, the handbook requires the chargepoint’s own schedule to be off; an energy-provider-controlled setup needs that provider’s supported configuration.

This procedure uses the original UK handbook, printed pages 239–240. Match a later G6 or different XOS layout to its supplied instructions.

Set one schedule and check it starts

1. Park and check that the battery is below the selected limit. Note the car, wallbox and energy-app schedules before changing them.
2. Open Charging and Discharging → Charging. Set the slow-charging time and check the displayed charging limit; Battery Health Protection can restore its default after the car powers on again.
3. When using the car as the scheduler, deactivate the wallbox’s schedule as the handbook requires. Connect and lock the plug. If your tariff provider controls the session, follow its setup instead of adding a competing timer.
4. Check a short supervised window when the supply is available. Waiting beforehand is expected; energy flowing at the requested time is the useful result. Restore your original tariff setup after a diagnostic comparison.

Charging check: stop for a fault warning, unusual heat, smell, damage or internally wet equipment. An immediate-charge comparison is only suitable without those symptoms, and electricity outside your tariff window may cost more.

The limit changes back, or the app cannot save it

On the earlier UK G6, enabled Battery Health Protection restores the default charge limit after the vehicle powers on again. The original UK handbook gives 90% for its ternary-lithium battery models and 100% for its LFP models. Those defaults depend on the actual battery; registration year alone does not identify it.

1. While parked, read the limit on the car under Charging and Discharging → Charging, together with the Battery Health Protection setting. For this charging session, set the intended target through the offered control and read the percentage back on the car.
2. If a previous target returned to the documented battery-specific default after power-on with protection enabled, that matches the handbook’s described behaviour. Check again before the next charge rather than assuming the app’s previous target is still active. The handbook recommends the default; do not switch protection off merely to conceal an unexplained mismatch.
3. If the app reports no/poor vehicle network access, use the car’s local charging screen to check the actual saved target. A rejected remote request is not confirmation that the car accepted the change. Compare the car’s network indicator and one other native online service; phone signal or media Bluetooth alone does not confirm vehicle data.
4. During a normal available session, check delivered energy and the car’s selected target. Reaching that limit is different from the wallbox pausing for its schedule. If the car’s limit itself changes without the documented power-on/default behaviour, note the before/after percentage, power-on timing, protection setting and full XOS for a saved-setting check.

If remote changes still fail but local changes work: keep using the verified local target for the immediate session and have XPENG check the vehicle’s connected-service/account provisioning. If local changes do not remain saved either, report that separate result; repeating the app request or raising the wallbox’s energy target will not repair an unsaved vehicle setting.

Using Ohme: “Charge to” and “Top up by” are different

Read the wording on your Ohme Charging screen. Charge to is a requested final battery level; Top up my car by is an amount to add. Where Ohme cannot read the vehicle’s battery level, its energy-added setup does not know your actual starting percentage.

1. Read the starting percentage directly in the G6 and check its chosen charge limit.
2. If Ohme shows Top up my car by, calculate the intended increase. For example, from 35% to 80% is a 45-percentage-point top-up, not an 80% top-up. This is a planning estimate; verify the car’s actual result.
3. On Ohme’s Charging page, tap the displayed target and Ready by time to review them. Check that the selected EV is the correct one. A change made after plugging in may be marked This session only; unplugging restores the saved routine.
4. When Ohme controls the schedule, avoid adding a competing vehicle timer. A scheduled plan can pause and restart several times; compare the actual battery percentage and delivered energy with the plan before treating a stopped-session notification as a full battery.
5. If you need immediate charging, Ohme’s Max charge → Turn on Max charge overrides its routines and price cap. It can use more expensive hours; use it deliberately, then return through Smart charge. It does not override the car’s charge limit or a fault.

If the target was missed: check the car’s limit, active timers, Ohme’s requested increase/final target and ready-by time. A pause inside a valid plan is different from a vehicle refusal. A “Suspended EV” error needs the vehicle-limit/timer checks, rather than repeatedly increasing the requested top-up.

Newer Ohme app: enter the car's battery level

Ohme's UK instructions for app 2.14.2 and later add a battery-level prompt for cars whose level it cannot retrieve. A final Charge Target can therefore appear without a live connection to your XPENG account. Use the controls actually shown; the older Top up by calculation above is for screens that still use that wording.

1. After plugging in, read the current battery percentage in the G6. If Ohme asks for it, enter that actual percentage and confirm, rather than accepting a different starting value.
2. Set the intended final Charge Target and Ready by time. Keep the car's own limit high enough for that intended target, without bypassing its battery-specific guidance.
3. Check Ohme's displayed starting level after each new plug-in. Its predicted or default level is not a fresh measurement from the car. Correct it when the prompt differs from the car.
4. When the session finishes, compare the G6's actual percentage with the target. If it falls short, first recheck the starting level, car limit and available schedule; increasing a percentage based on the wrong starting value repeats the mistake.

The car and Ohme show different charging times

First compare their targets and whether charging is active or scheduled. A car's remaining-time estimate during charging and a smart charger's Ready by plan are not necessarily counting the same thing: the plan can include waiting periods. Use the G6 screen for its current battery level and Ohme's plan for when it intends to supply energy.

1. Read both screens at the same time. Compare the actual battery percentage, the car's charge limit, Ohme's target and Ready by time. Refresh a stale phone app; do not compare an old remote reading with the current dashboard.
2. If Ohme says Scheduled or its graph contains a pause, allow for that waiting time. Check whether delivered energy rises during an active slot. A charging-complete notification after one slot does not by itself prove the final target has been reached.
3. For a rough continuous-charge check, divide the energy still needed by the observed charging power: 20 kWh ÷ 7 kW is about 2 hours 51 minutes before losses, heating or pauses. This is arithmetic, not a promise that your battery needs 20 kWh or your supply delivers 7 kW.
4. If the plan cannot finish before departure, adjust its target/time or deliberately use the Max Charge control explained above, checking tariff cost first. Recheck that energy is actually flowing. If both systems show active charging but no energy is added, use the connection/supply checks below rather than trusting either countdown.

Success: the car reaches the intended target by your required time. A closer-looking countdown is not the success test; the resulting battery level is.

How often should an LFP G6 reach 100%?

For an LFP G6 covered by the earlier UK handbook or the 2025 English RHD handbook, the maintenance recommendation is a full charge to 100% at least once every two weeks or 1,000 km (about 620 miles). These editions also recommend keeping the LFP charge limit at 100% during regular use, and permit either AC or rapid charging for the recurring full charge. This is LFP-specific guidance; keep the different battery-specific default above for a ternary/NCM car.

Make it part of a normal available charging session. Confirm that your actual battery is LFP, then on the earlier UK layout open Charging and Discharging → Charging, set the charge limit to 100% and read it back. Allow enough time for the car to finish, with the wallbox/supplier also permitting supply. Check 100% on the car, not only a charger's estimated completion or battery percentage. Do not deliberately discharge the battery to empty first.

The handbooks link this routine to accurate range estimation and battery care. A calibration request does not by itself establish battery-capacity loss. If a request remains or the car itself stops at 99%, the complete car/charger checks immediately below distinguish a finished session from an interrupted full charge. A full charge is not a remedy for an active battery fault warning.

Stops at 99% and asks for battery calibration

First read the percentage and message in the G6, rather than relying on Ohme's predicted level. For a car matching the 2025 English RHD handbook, the message "The battery status needs to be calibrated" calls for a full charge to 100%; AC charging is one of its recommended options.

1. If the car already shows 100% but Ohme shows 99%, use the car's reading. Check whether the calibration message is still present. A different charger estimate is not a reason to add more charge to an already full battery.
2. If the car itself is at 99%, read back its saved charge limit. For the requested full charge, set and confirm 100% on the matching vehicle screen. Check that a separate car timer is not preventing supply. If Ohme asks for the starting level, enter the car's actual current percentage.
3. For one available AC session, allow charging to finish. If Ohme's planned session has ended short, use Max charge → Turn on Max charge deliberately. It temporarily overrides Ohme routines and the price cap, so it can use higher-priced hours. The car still controls its own limit and acceptance. If energy is still being added, let the session progress instead of repeatedly disconnecting at 99%.
4. Check the car's completion state and the message. After the car reaches 100%, check whether the calibration prompt clears; do not assume an Ohme completion notice proves that result. Return Ohme to Smart charge for the normal schedule and verify the intended settings for the next session.

Still at 99%, or still asking after a full charge? Keep the actual car percentage, saved limit, car charging/stop message, Ohme state and full XOS version. If Max Charge is supplying but the car stops accepting below its target, ask XPENG to check full-charge completion and the battery-state calibration conditions for that car. If the car is requesting charge but Ohme is not supplying, those two simultaneous states give Ohme a specific session/supply check. A 99% finish alone does not identify a failed battery or prove an Ohme software fault.

If charging does not start

Check the target, clocks and all active timers. If there is no warning or damage, note the original tariff timers, then temporarily turn off the car’s slow-charging schedule under Charging and Discharging → Charging for one short supervised session when the wallbox/provider also permits supply. Working now but not in the intended window points towards timer interaction: correct the clocks/window and restore one supported scheduling setup. Failing both ways points towards the connection or supply rather than its clock.

Give the chargepoint operator the unit ID, time and both status messages. For recurring vehicle-side scheduling failure, give XPENG the model/build, full XOS, target, clock times, active schedules and comparison result; ask it to check the saved schedule and known issues for that build. Do not use a battery disconnect or emergency cable release for a timer problem.
