A session that starts at midnight and dies at 2am is usually a setting, not a failed board. The charger schedule, the car's own schedule, a randomised delay under the smart charge point rules, a load-management clamp, a tariff that only allows a short window, or a plug that was not fully latched are the common causes. A protective device that has tripped is the less common and more serious one.

What a survey must prove about home EV charger stops halfway through the night
Set one scheduler, not two, unless you understand which one is in charge. Photograph the session log.
Home EV charger stops halfway through the night and the written scope
This is often free to solve. Paying for a bigger charger will not fix a timer. Paying for a call-out is fair if the installer left two systems half configured.
The expensive shortcut on home EV charger stops halfway through the night
The mistake is repeating 'it only charges to 50 miles' without saying you set a limit in the car. Another is disabling smart features in a way that leaves the unit outside its approval conditions.
Handover when home EV charger stops halfway through the night is the issue
On handover, run a short scheduled test and agree who owns the settings: you, the tariff, or the installer. Write down the one schedule you intend to keep.
Home EV charger stops halfway through the night
Check whether the RCD is still closed before you rebook the installer. Then look at both apps. Two schedules fighting each other is a classic: the charger starts at 00:30 and the car stops at 02:00 because its departure timer thinks the journey is short.
- Check the RCD first
- Car timers and charger timers conflict
- Smart rules include a random delay
- A short test on handover prevents a week of guesswork
Frequently asked questions
Why did it start late?
UK smart charge points use a randomised delay so every car in the street does not start on the same second. A short wait can be normal.
Why does it charge slowly after 2am?
Load management may be backing off, or the tariff window may have ended, or the car may be warm and balancing. Read the session log.
Can I force a boost?
Most smart chargers have an override. Use it when you need the miles, and put the schedule back afterwards.
When is it a fault?
If the protective device opens, the lead is hot, or the unit is dead with no lights, stop and call the installer.
