A charger that stops in the middle of the night usually met a small event while nobody was watching — a brief supply dip, a tariff window closing, a protection pause. The lost charge is rarely the event itself: many chargers, once stopped, simply wait to be told to start again, so a two-minute interruption becomes a lost night. Whether yours resumes on its own is a behaviour its maker designed and its manual states.
Key Takeaways
- Overnight stops usually trace to a small event: a dip, a closing window, a pause, the car finishing.
- The lost night is the resume behaviour: many chargers wait to be restarted once stopped.
- Your unit’s resume behaviour is stated in its manual — or it is a question to ask in writing.
- Schedule margin and one timing source mean one event cannot cost the whole night.
The Small Events That Happen While You Sleep
| Overnight event | What it does to the session | Does the night recover? |
|---|---|---|
| A supply dip or a brief outage | The session drops. What happens when power returns is the maker’s design choice. | Only if the unit is designed to resume |
| The off-peak window ends, or a schedule completes | The session ends as set — car or charger obeyed its timing | Nothing is broken; the window was shorter than the charge needed |
| A thermal pause on a warm night | The unit pauses or steps down to protect itself | Some units resume when cool; others end the session there |
| The car reaches its own charge limit | The session ends by design, earlier than expected | Nothing to resume — the car is done |
| The network drops on a platform-dependent session | A session that needs its platform can end when connectivity does | Depends on the platform’s design |
None of these is dramatic. Daytime, you would replug or tap the app and lose five minutes. Overnight, the same event idles the car until you wake — the symptom reads as “it stopped all night” when the event lasted moments. Sessions ending at a set percentage or clock time are settings doing their job, not an interruption; leaving an EV charging overnight is normal practice.
Stopped Often Means Waiting for You
Automatic resume is a designed behaviour, not a default of charging. Makers choose differently: some units restart when supply returns, some hold the session open, and some end it cleanly and wait for a replug or an app start. The manual states which behaviour your unit has — look for its wording on restarting after a power interruption, and check app settings only where the maker provides one. Where both say nothing, treat it as unknown and ask the maker in writing.
The Morning Evidence Checklist
- The car’s charge level against what you expected — how much of the night was lost.
- Any message on the charger, car or app — record it word for word before it clears.
- The breaker, if found tripped: the night ended with a protection event — see our guide to why an EV charger keeps tripping the breaker.
- The session record, where the platform keeps one: the stop time turns “sometime in the night” into a clue.
Setting Up So One Event Cannot Cost the Whole Night
- Leave margin in the schedule: a window comfortably longer than the charge needs absorbs a pause and a restart.
- Keep timing in one place — car or charger — so a window edge is your decision, not a surprise (see our guide to smart charging and time-of-use scheduling).
- Learn your unit’s resume behaviour before you depend on it, and if it never resumes on its own, start earlier so a single event still leaves a usable charge.
App-Connected EVDANCE Chargers for Overnight Charging
The EV-ACT3204PE wallbox states RFID and app control on a 22 kW three-phase Type 2 unit. The EV-ACS3210E portable states an app with energy monitoring, at 32 A Type 2 and about 7 kW single-phase. Neither listing states an automatic-resume behaviour — if overnight reliability decides your purchase, ask us in writing for the exact model.
Frequently Asked Questions
It stopped once, at about 3 a.m. Should I worry?
A single overnight stop with enough charge by morning is evidence to file, not a fault to chase. Record the stop time. If it repeats, the pattern across nights points at the event class above.
My car was fully charged anyway. Did anything fail?
No. Cars end sessions by design at their set limit; a full battery in the morning means the “stop” was the finish. The checklist matters only when the car is short of its target.
Can I make it restart automatically?
Only if the maker built that behaviour into your unit; the manual states it where it exists. There is no universal switch, and no car setting can restart a charger that has ended its session.
