Ik rijd sinds kort met een MX30, als extra wagen bij mijn Tesla S. Ik heb een Tesla wall charger (eerste model) Mijn MX30 wil niet laden aan die paal. (is 2 x gelukt na veel miserie)
Aan die paal laden wel ander EV's, echter MX-30 doet raar. Mazda Belgium weet geen raad.

Nog iemand met dit probleem? Iemand een oplossing?

------------------

Mijn Wallcharger: 3fase 400V +neuter die 32 A kan leveren wat correspondeert met 22.2kW vermogen
De MX30 is gelimiteerd op monofasig 6.6kWh.
De walbox heeft dus ruim voldoende vermogen.



I have recently been driving an MX30 as an extra car with my Tesla S. I have a Tesla wall charger (first model) My MX30 does not want to charge at that pole. (has succeeded twice after a lot of misery)
Other EVs do charge at that pole, but MX-30 is acting weird. Mazda Belgium does not know what to do.

Anyone else with this problem? Anyone have a solution?



My Wallcharger: 3-phase 400V +neuter that can supply 32 A which corresponds to 22.2kW power
The MX30 is limited to single phase 6.6kWh.
The walbox therefore has more than enough power.

Just to confirm...the car charges fine at other charge points just not the tesla home charge point?

Ik kan me er iets bij voorstellen, dat de tesla lader een tesla laadsysteem verwacht 3fase, maar in de stress raakt omdat er maar 1 fase gebruikt wordt als je de mazda eraan hangt. (ongelijke belasting over de 3 fase.)
Wij hebben een newmotion 11kw wandlader en dat werkt prima voor onze tesla model 3 en de mx30.

Yes, the MX30 charges via the regular 220 socket and also at the charging stations along the open road.

(Dutch: Ja, ze laadt via het gewone stopcontact 220 en ook aan de laadpalen langs de openabere weg.)

Begrijp ik wel gedeeltelijk. Maar het zou spijtig zijn dat Mazda dat niet kan oplossen. Andere EV's kunnen wel aan onze laadpaal laden. Deze Tesla laadpaal is een zogezegde "domme" paal. Er zit niets van software of technology in. Op de polen zit de juiste stroom. Het is net alsof de wagen zelf niet altijd "durft".
Waarom soms wel, en soms niet?
In het begin kreeg ik een melding op de app: "Laadsysteem is defect. Kan hoogspanningsaccu niet laden. Laat de auto door een deskundige reparateur nakijken."
Mazda heeft de wagen uitgelezen en heeft daar verder niets meer over gezegd. Alleen, dat Mazda een andere paal willen zetten... op hun kosten.

Bij de aankoop van deze MX30 werd er gezegd dat het geen probleem zou zijn om aan onze Tasla Wallcharger te laden.

Ik gewoon onze paal behouden, Waarom kan een Mazda MX30 daar niet op laden?

Hello Paul here from U.K. Not sure if I’m right in saying this but here in U.K. we use single phase for domestic supplies. Could it be that your 3 phase is the problem. I know that in Malta once a domestic supply reaches a certain amount of load they swap up to 3 phase. Could it be that the Mx 30 is maybe a single phase spec. Must admit that Mazda should know this. Just trying to help but I could be totally wrong.

 

[Mares X]

Hi Paul, thank you for your contribution. It could be. It is indeed strange that Mazda does not make this comment. But why can other electric cars charge?
It's the car that has to react and think, I can't handle 3 phases, I take what I need. But no, he doesn't respond or 1 in 10 times he wants to load.

Indeed Paul, with the classic fast chargers along the street it works. But not at my own Tesla charging station.

I think that it is mostly likely due to improper communications between the car and the charge point. As you have a tethered lead, you can't try another cable so my only suggestion is that you clean the comms connections. Try surgical alcohol. Give them (car socket and wall plug) a good clean and then wet connectors with wd40 when you are done. Though I don't think it will be the live connection, to be sure, clean L1 on the plug and at the car. As MX is single phase, it is not using L2 & 3.

 

[Mares X]

Indeed, it is probably a miscommunication. I have already cleaned the connectors.
But Mazda importer does not respond to that and propose to put another pole. Which is a bit too simple.

I just wanted to find out if there are any other MX riders with this problem.
Whether or not being able to charge with a simple Tesla Wallcharger.

Nederlands:

Inderdaad, Het is waarschijnlijk een mis communicatie. De connectoren heb ik al gereingd.
Maar Mazda inporteur reageert daar niet op en stel voor eenander paal te zetten. Wat een beetje te simpel is.

Ik wou gewoon uitzoeken of er nog MXrijders zijn met dit probleem.
Wel of niet kunnen laden aan een eenvoudige Wallcharger van Tesla.

 

[Milkfloat]

OK Mares X. In that case, I think we are both saying the same thing. But, if it is a plug/cable issue, the manufacturer of the charge point is not particularly relevant. I think that the PP link is working because the car recognises that it has been connected. The CP link is probably the issue. Intermittent failure of the signalling cable in your tethered lead could be an answer. Some of the early leads had very thin comms cables.

 

[Paul]

Just an idea, does the Tesla charger respond to other ev’s? If not milkfloat may well be right.

What do you mean by PP link and CP link

I already know that an EV Mercedes will charge my Tesla Wallcharger.

 

[Milkfloat]

This is the pin layout.

PP = Proximity pilot: pre-insertion signalling
CP = Control pilot: post-insertion signalling
I suspect that you have an error with CP
It's a pain changing a tethered cable without a certain cause but I suspect that it is the root of the problem.
I would still try cleaning the CP pin and socket again and wet them with WD40.

 

[Milkfloat]

Link was blocked, sorry.

 

[Thebriggie]

Milkfloat a couple of questions for my understanding. If other evs can charge on that point as stated do they also use the cp link? If the mx30 can charge at other points does that mean the cp link in the car must be fine?

Mares x, do you know anyone locally with a tesla first gen charger you could do a test on to eliminate the mx30 being the problem? (Is there a similar tesla forum to ask?)

It seems to me its a process of eliminating potential problem areas one by one..

Yes, all EV's use the same protocol and I believe that there is a better than 80% chance that the fault lies in this area.
You said that the MX-30 charges on the open road. Were they fast DC chargers or AC chargers (doesn't matter if they were single or 3 phase as the Mazda can only use 1 phase). That is important as the systems and the control logic are separate.
If your Tesla charger has charged other EV's and your Mazda has charged on other AC stations then there are only connection and software variables left. You really need cooperation from Mazda to check the system through thoroughly. Checking on another 1st gen Tesla is a good idea as it could highlight a software incompatibility.
