Yes, most smart home chargers have a timer, usually called scheduling, that you set in the charger’s app. You plug in when you get home and the charger holds off until the cheap overnight hours, then starts on its own. If your charger has no timer, your car almost certainly does: nearly every EV offers scheduled charging in its own settings.
Key Takeaways
- Most smart home chargers include a scheduling timer in their app.
- Your car has its own timer too; use one or the other, not both at once.
- The point of the timer is off-peak pricing: plug in early, charge cheap overnight.
- British charge points ship with off-peak default settings under the 2021 smart charging regulations.
Two Places the Timer Can Live
| Timer location | How it works | Best for |
|---|---|---|
| Charger app | The wallbox or portable unit stores the schedule and starts power at the set time | Households where different cars share one charger |
| The car itself | The EV waits after plug-in and charges in its set window | Drivers whose charger is a basic model |
Pick one timer and use only that one. If the car and the charger both hold schedules, they can block each other: the charger wakes up to find the car asleep, or the car asks for power before the charger is willing. Our overview of wallbox features, including scheduling, shows how timers sit alongside displays and load management, and how smart chargers work covers the control behind them.
Why Bother: Off-Peak Tariffs
The timer exists to move charging into cheaper hours. Many utilities sell time-of-use or dedicated EV tariffs with low overnight rates, and scheduling is how you capture them without staying up. Most of those tariffs need a smart meter, which is a separate question we answer in do you need a smart meter for an EV charger. In Great Britain the nudge is built in: under the Smart Charge Points Regulations 2021, charge points must offer scheduling and arrive with default settings that steer charging away from peak hours. What the time shift saves you depends on your rates; the arithmetic is in what it costs to charge an electric car at home.
Setting It Up
- Find your tariff’s off-peak window and set the charger’s start time inside it.
- If your app or car offers a target charge level or finish time, set that too, so the battery is ready when you leave.
- Plug in as soon as you get home and confirm the unit shows a scheduled or delayed state, not an error.
- Check the session record the next morning; one successful night confirms the setup.
- Leave an override in mind: most apps have a “charge now” option for unplanned trips.
When a Timer Is Not the Whole Answer
A timer fixes when charging happens; it does not fix how much power your home can spare. If the charger must slow down when other appliances run, that is load management, a separate feature. Schedules also do not precondition the cabin or manage battery temperature; those departure features live in the car. If you are choosing a charger around these features, app-connected wallboxes such as the EV-ACT3204PE (22 kW, Type 2, RFID and app control) put scheduling in the app; check the feature list of the exact model you buy, because timer functions vary. The wider range is on our residential charging page.
Frequently Asked Questions
Do portable EV chargers have timers?
Most basic portable cords do not; you plug in and charging starts. Some app-connected models add scheduling. Otherwise, use the car’s built-in timer, which works with any portable charger.
Will scheduled charging harm the battery?
No. A timer changes when the car charges, not how. The car still controls the session, and spending fewer hours sitting at a full charge is generally considered the gentler pattern.
What happens if I need the car before the scheduled start?
Use the override. Apps and cars both let you start charging immediately for one session without deleting the stored schedule.
