Repeated failure to charge overnight - what’s causing it (Zappi charger)?

I’ve been experiencing repeated failures to charge overnight, after setting charge time on the OVO Charge app (which recently supplanted the Charge anytime app).

If I set a time just a few hours away from the present, it will always charge without issue, but setting a morning deadline maybe 9-12 hours away seems to cause issue for some reason.

From previous experience of overnight charge failures, then one successful charge, I surmised I needed to set the time on the app before I plug in the car, because that was the only thing I did differently that time.

However, doing that, still no charge on multiple mornings, despite typically a spike of activity in the late evening, and the OVO app stating charging would recommence in the small hours.

Trying to see if there’s any app issues, looking at my Zappi app, it makes a reference to the deleted Charge Anytime app (see screenshot): I don’t know if this has any impact on the failure to charge or not? I’d presumed not, since it doesn’t affect immediate charging in any way. And anyway I can’t see any way to change it, unless maybe I reset it, but heaven knows what might happen, so I have to reset its links with my EVSE charger etc.

I can’t see any way not to set a time on OVO Charge, so trying to set up a time in the car instead would only just add another factor in the equation that can’t help.

I’d welcome thoughts: anyone else had similar issues with this combo? Is it something to do with the OVO Charge app not working, or the way the Zappi app interacts with it?

Seems the only way I can guarantee a charge is to set a time for later in the evening and charge it fully immediately after plugging in, leaving it sitting if I need it, at 100% overnight, rather than hitting that just before use, obviously not ideal.

Unfortunate the app doesn’t work as intended and allow delayed overnight charging, instead of just immediate.

Hi ​@albannach ,

I generally recommend giving the team a call in situations like this, as they need to run diagnostics. Try 0330 175 9678.

You can download the new OVO Charge app from the App Store or Google Play. The Charge Anytime contact details, and useful topics can be found here:

Hey ​@albannach 

 

I’m glad to see Blastoise186 has already stopped by with some really helpful advice on this for you, have you been able to reach out to the team for support on this yet?

 

If not, I’d definitely agree with Blastoise that contacting the Charge Anytime team will hopefully help here. You can find all contact methods for the team on the topic below if calling isn’t most convenient for you:

 

 

I hope this helps, do let us know how you get on.

Hello Abby and blastoise.

 

Yes, I was able to call yesterday and the diagnosis was that my make of car goes to sleep and doesn’t get woken up by an early morning charge.

 

So in the meantime I just need to charge last thing, and suggest to myenergi that they set it up to send a small regular pulse of charge to keep the car awake and contact the manufacturer.

 

I haven't tried it yet, but I have read a way to wake it up for charge is to switch on climate control from the car’s app, so I can do that before going to bed and don’t have to go out in the wintry cold to unlock it to wake it up.  I’ll test that and report back.

Hey ​@albannach 

 

Thanks for the update, I’m glad to hear you’ve been able to get somewhere and hopefully have a solution too!

 

Do let us know how you get on with that, it could be very helpful for others to know, especially if setting the climate control does help keep it active.

For whatever reason, charging has not failed to happen once since I raised this.

 

Not just when plugging in in evening, but even earlier in the day, it has still charged overnight.

 

So I haven’t been able to test any ‘wake up’ action via the car app.

 

If there’s anything further to update, I’ll report back.
