Hallo .
I am an owner of an mx30 with registration on 9/2020 . I am in europe , so it is the European edition.
The model is premium comfort vintage first edition.
Today as I was sitting in the drivers seat and playing with the menu to get familiar, the little red and yellow lights in the drivers screen started turning on off for several times , 20 times (nearly) and the the whole car blacked out.
Nothing can be turned on, everything is black, and I mean nothing. The doors can not be locked , no button has power.
I though that is strange ....so I tried to charge the car n case it run out of power. (the power indicator was 50% before that happened, but anyway).
I plugged the car in the wall plug. The car has no indication of charging( no lights, no red, no blue nothing, just dead)
That happened three hours ago. What the hell is that.
Obviously I called mazda , and they will pick the car on monday.
i am left with no car during weekend.
Thank God I was home in my garage.

Look at section 7.23 to 7.25 of the manual, Depleted Lead-Acid Battery. (Spot the deliberate mistake in 7.25!) Don't bother with the jump lead instruction, just disconnect the terminals and put a charger on the battery. Charge according to the output from your charger. Reconnect terminals and everything should work Mazda dealer can then drive the car and find out why DC to DC charging didn't work.

Thank you. I will do that and inform the community.

To initiate DC to DC you need to establish communication between car and station. For this you need a battery power:)

By DC to DC, I meant the the 350 volt to 12 volt charger in the car that keeps the lead acid battery charged. Of course, it could be many other things as 12 volt battery failure is probably the biggest cause of BEV breakdowns. Ask Nissan Leaf owners and it has already been reported in VW id's.

If you sit for a long time in the car for cheking out the functions or listen to music waiting for someone you best start the driving mode or your litlle battery can deplete quit fast
It will only charge when ingaging driving mode not in accerory mode when loading

I have tried to find out the 12 volt battery charge rate without success. With some crude trials, I have come to the conclusion that it charges at about 40 amps but I could be some way off being correct. That is about half the rate of a typical ICE car. Of course, there is no starter motor to take a chunk of energy out of the battery but, lights, heated seats, wipers etc. are all driven off the 12 volt system. So, if one is doing lots of short trips with lots of 12 volt use, it is possible to get to a low state of 12 volt battery charge. As Groupie says above, the battery only charges when the car is in "Ready" mode. If I am conscious of having done mostly short trips, I put the 12 volt charger on at the same time as I charge the high tension battery. I have seen the little battery accept about 8 amperehour.
