Thank you for your answer - interesting that you experience the problems also at higher temperatures.
I will soon know if my problems goes away (doubt it) as the outside temperature is rising again.

I followed the thread and saw the discussion about why charging resumes for short intervals even after the target has been reached.
I recently experienced exactly that:

• Charged (using WB) from 35 % to my set limit - 90% - over a 6 hour period.
• During this period there was just one unexpected off/on cycle shortly after the charging began.
• The car was left plugged in after the limit had been reached and charging ended.
• Then, after 2 hours, the on/off cycling began.
• Each on/off cycle lasted for 2 - 4 minutes.
• The cycles came at irregular intervals, anything from 1 to 6 cycles / hour.
• And of course they managed to charge the battery past the 90% limit.

I have been trying to be by the car several times hoping to catch one of these cycles as they happen but so far no luck.
Want to find out if there is any fault signal or such from the WB.

In my next test will use the charger that came with the car and see if the problem is the same.

Anyway, good to know that I am not alone in this?
I'm in touch with my Mazda dealer here in Sweden and if anything poitive happens I will share it.

And thank you for letting me communicate in English.
By the way, I have added the word "mausetot" to my limited German vocabulary.

Saftschubse  Aslan What I’m saying is - has anyone else seen a link beteeen a low outside temperature and the charging on/off problem that both me and Aslan seem to have?

Sorry that I have to write in English but my German doesn’t go that far.

Using a Swedish WB, make is GARO, installed last year.

I had exactly the same problem - on/off the whole night and an empty 12V-battery in the morning.

My car sits outside and this happened when the outside temperature fell to appr. - 10 degC.

Never saw the problem before it got cold ouside.

But there has often been a few unexpected notifications from the app saying ....charging / .... ..charged also at higher outside temperatures.

SW update by my Mazda dealer didn’t help

No problem charging from a normal wallsocket at - 10 degC when using the supplied cable with its built-in control box - worked perfectly witout interruptions. Basing this on the fact that I only got two notifications from the app. One when charging began and one when it finished.

Zitat von Aslan

Hallo,

ich habe meinen MX 30 im November angemeldet und folgendes Ladeproblem: Wenn ich an der Wallbox über Nacht lade, ist die Hochvoltbatterie geladen, aber die Bordbatterie mausetot. Ich habe dann festgestellt, dass der MX30 erkennt, dass er voll geladen hat, den Ladevorgang beendet, nach ca. 5 Minuten den Ladevorgang erneut startet und das ganze im permanenten Wechsel die ganze Nacht durch. Damit arbeitet das Bordnetz nahezu durchgehend und die Bordbatterie ist leer. Über die App kommen auch die Meldungen rein "die Batterie ist nun geladen" und 5 Minuten später "das Fahrzeug wird geladen". Das geht dann abwechselnd permanent, bis die Bordbatterie leer ist.

Sicherlich laden viele mit dem mitgelieferten Ladegerät oder stecken ab, wenn er voll ist. Aber hat hier jemand diese Erfahrung an der Wallbox auch gemacht, dass der MX 30 den Ladevorgang immer wieder neu startet, wenn er an der Wallbox eingesteckt bleibt (was man ja macht, wenn man über Nacht laden möchte)? Hat jemand eine Lösung dafür?

Da ich bereits mehrere Fahrzeuge an der Wallbox unter gleichen Bedingungen geladen habe, gehe ich davon aus, dass das Problem an der Steuersoftware des MX 30 liegt...
