# How to Set Up a Charging Schedule

By EV Charge Cables · Published 18 October 2026

**The short version**

A charging schedule starts your EV automatically in the off-peak window so you wake up to a charged car and a lower electricity bill.

- Use your car's touchscreen menu or manufacturer app to set a departure time and charge limit
- A smart wallbox app can integrate with your tariff and adjust the window automatically
- Plug in every night even if you do not need much charge; the schedule only runs when the cable is connected

Setting a charging schedule means your car automatically begins charging at the time that suits you, without any action needed when you get home. For most owners, this means targeting the overnight off-peak window to keep costs down, while ensuring the car is charged to the level you need by the time you leave. Most modern electric cars have a built-in scheduler, and many smart wallboxes add a layer of remote control on top of that. The process takes a few minutes to set up and then runs itself. Pair it with a reliable [Type 2 charging cable](https://www.evchargecable.co.uk/type-2-charging-cables) and you have a home charging routine that is both cheap and automatic.

| Scheduling method | Where to find it | What it controls |
| --- | --- | --- |
| Car in-cabin menu | Touchscreen or infotainment, under "Charging" or "Energy" | Departure time, start time, charge limit |
| Car manufacturer app | Smartphone app provided by the car brand | Same as in-cabin, plus remote monitoring |
| Smart wallbox app | App from your charger brand (Ohme, Zappi, Easee, etc.) | Start/stop time, tariff integration, load balancing |
| Energy supplier app | Supplier's own app if you have a smart EV tariff | Automatic charging in cheapest window, sometimes with export control |
| Home automation system | Smart home platforms linked to wallbox | Complex rules combining solar, grid price, and household load |

### How do you set a charging schedule through the car itself?

On most electric cars, the charging schedule lives in the touchscreen menu under a label such as "Charging", "Energy", or "Departure". You set a departure time, and the car works backwards to ensure it reaches your chosen charge level before you leave. You can usually set different schedules for weekdays and weekends. The car will start charging automatically once the cable is plugged in and the scheduled window begins. If you want to charge immediately rather than wait for the window, there is usually an override button on the screen or the car's charging port.

### What does a smart wallbox add to scheduling?

A smart wallbox connects to your home Wi-Fi and is controlled via a smartphone app. This lets you adjust the schedule remotely, see real-time energy use, and in some cases integrate directly with your energy tariff so the wallbox automatically selects the cheapest charging window without you setting exact times. Some models integrate with solar panel systems, pausing charging when solar generation drops and resuming it when the panels are producing surplus power. If you are on a time-of-use tariff and want the schedule to adapt automatically when off-peak hours shift or change, a smart wallbox is a worthwhile upgrade.

### Should you use the car schedule, the wallbox schedule, or both?

In most set-ups, it is better to choose one source of scheduling and let it take control. Running conflicting schedules from both the car and the wallbox can cause unexpected behaviour, where one overrides the other or charging begins at the wrong time. If your wallbox app has good scheduling features and integrates with your tariff, let it control the session and disable the car's own scheduler. If you do not have a smart wallbox, use the car's built-in scheduler. Your wallbox manual or the manufacturer's support page will clarify which approach is recommended for your combination of car and charger.

### How do you set a charge limit as part of the schedule?

Most scheduled charging set-ups allow you to set a target charge level as well as a time. For everyday use, limiting charging to around 80% is widely recommended to help preserve long-term battery health. Reserve a full charge for long journeys where you need the full range. In the car's menu, look for a charge limit slider or percentage setting alongside the schedule settings. Some wallbox apps have a similar option. Set the limit once and it will apply to every scheduled session until you change it, so you do not have to think about it each night.

### What if your off-peak window changes?

UK off-peak windows vary by tariff and can be updated by your energy supplier. If you are on Economy 7, the window is fixed and stable. If you are on a dynamic tariff where cheapest hours shift each day, a smart wallbox or energy supplier app that automatically finds the cheapest window is more useful than a fixed time schedule, because it adjusts without any action from you. Check what your tariff promises: some smart EV tariffs guarantee a minimum number of cheap hours regardless of demand, while others vary. Your supplier's app should show the scheduled window for the coming night.

### What happens if you forget to plug in?

Nothing automatic. The car can only follow its schedule if a cable is connected. This is why most EV owners develop the habit of plugging in every time they arrive home, even if they do not need a full charge that night. The car's schedule will not run at all if the cable is disconnected. Some wallboxes can send a reminder notification to your phone if the car has not been plugged in by a certain time, which is a useful safety net for busy households.

### Frequently asked questions

#### Can I set different schedules for different days of the week?

Most modern EVs and smart wallboxes allow per-day scheduling. You can set a later departure on weekends and an earlier one on weekdays, for example, so the charge level and timing adjust automatically. Check your car's manual or the wallbox app to confirm the day-by-day scheduling options available on your specific set-up.

#### What if I need a full charge urgently outside the scheduled window?

Every scheduling system has an immediate override. In the car, there is usually a button or menu option to start charging now regardless of the schedule. In a wallbox app, you can typically trigger an immediate session from the app. You will pay the standard tariff rate for any electricity drawn outside the off-peak window, but the flexibility is always there when you need it.

#### Does pre-conditioning work with a charging schedule?

Yes. Most EVs that support cabin pre-conditioning allow you to link it to your departure time. The car will warm or cool the interior while still plugged in, using grid electricity rather than battery power, so you leave with a full charge and a comfortable cabin. Set the departure time in the car's schedule and enable pre-conditioning in the relevant menu.

#### Will the schedule still work if I change my departure time one morning?

You can override the departure time from the car's screen or the manufacturer's app at any time. If you know the night before, change it then so the car has time to plan. If you need to leave earlier than planned on the morning itself, plug into a public charger or use whatever charge is available; a partial battery is rarely a problem for short journeys.

#### Is there a risk of overcharging if the schedule is set incorrectly?

No. Battery management systems prevent overcharging by design. Even if the schedule runs for longer than expected, the car stops accepting charge once it reaches 100% (or your set limit). You cannot damage the battery by leaving the car plugged in too long.

#### Do public charge points support scheduled charging?

Generally, no. Public chargers begin charging as soon as you authenticate and plug in. Some networks have apps that allow session management, but the precise scheduled start-time control you have at home is not typically available at public charge points. Scheduled overnight charging is a home-specific advantage.

Once your schedule is set, home charging becomes completely hands-off.
