Bought my MX-30 in November 2021 with this specs : AC charging at 6.6 kW and DC charging at 50 kW. The 6.6 kW is real, but I've not been able to get over 36 kW using Combo CCS.
On Mazda website, the specs are now 11 kW for AC and 50 kW for DC.

My dealer isn't very aware of the EV technologies so I'm asking here : Does anybody knows if it possible to upgrade the charge rate by software update ?
I know Skoda did it for the Enyaq and probably read some other manufacturer also changed the charge rate.
I think it's not possible to upgrade the AC charge rate by software even if it would be very cool to have 11 kW on our small battery.
But 50 kW on DC should be possible as far as I know.

I really hope it can be fixed with software, it would make a massive difference with our small battery. Polestar and Volvo has also improved charging with software a massive amount too.

11kW AC charging is 3 phase and i don't think the current cars are wired up for that so it would probably be a hardware swap. Having said that all the parts are off the shelf so they may be software limited

In a minor update, Mazda have announced that the MX-30 now leaves the factory able to accept 50kW. As the battery remains the same, one must assume that the change is software enabled. So, perhaps a future upgrade to existing cars will be possible. However, there is no mention of any change to the charge curve. If that remains the same shape as existing or has an even shorter duration peak than now, it may make precious little real difference.

Im more interested in 50kw fast charging then 3 phase at home as i can't charge at home anyway. I live in an apartment in Gothenburg, Sweden.

Baz, the car can handle 3 phase but most of the domestic supplies in the UK are single phase. In Europe 3 phase is common and the European spec, including us...still, can take 1 or 3 phase. Most of our domestic chargers can only pump out 7kw single phase anyway so no change there anyway!

Quote - You can charge your Mazda MX-30 with a Type 2 connector at home, work or at a public charging point. There is also a CCS connector for rapid charging.

Cool, wasn't sure if only pin 1 was connected internally

 

[Thebriggie]

Baz on saying that the cable supplied with the car is only single phase...so I think I need to do a bit more research in case I have been sold a dummy!!

Baz, I stand corrected. Mazda specified the car for 2/3 phase ac charging and informed some partners accordingly. . However it seems when the final car was produced it was single phase. Hence the confusion with most charging sites telling us the car could handle 3 phase. Even the dealership thought 3 phase but understandably so. It would appear European 2/3 phase chargers merge the phases into a single phase. Having looked at the cable and the car it would appear L2 and L3 are blanked out. So the new car must have L2 and L3 active and therefore, as well as a possible h/w and s/w update, it would appear a new cable may also be required. Our continental colleagues may confirm if indeed 2 or 3 phase charging is merged into 1 but it seems 99.9% correct. So on that basis it would need a new ac/dc charger, new socket and wiring etc. Wasted in the UK as you stated. Apologies

11kW isn't that useful in the UK as most of our chargers are 7 / 22 - but i can see it being useful where 11kW chargers are prolific as at the moment our model of car would only charge at 3.6 on an 11kW charger

I think you got some things mixed up. 22 kW is also 3-phase, but 7 kW is 1-phase. The table basically looks as follows:

Charge point	Maximum power	Max. Charge power	MX-30 2020/2021 (1-phase)	MX-30 2022+ (3-phase)
1-phase 16A	230V / 1x16A	3.7 kW	3.7 kW	3.7 kW
1-phase 32A	230V / 1x32A	7.4 kW	7.4 kW	7.4 kW
3-phase 16A	230V / 3x16A	11 kW	3.7 kW	11 kW
3-phase 32A	230V / 3x32A	22 kW	7.4 kW	11 kW

It's actually quite simply: since the 2020/2021 MX-30 has only 1-phase, it's always limited by the amps over that single phase. So 16A will net the same max charge power regardles of whether the charge is in fact 1-phase or 3-phase.

The MX-30 2022+ with 3-phase onboard charger has a maximum 3-phase power of 11 kW (some cars like the Renault ZOE do 22 kW) but it can still do 32A over 1-phase (7.4 kW) or 3x16A (11 kW). Meaning that even if you connect to a 22 kW charge point (and over here in The Netherlands we even have 17 kW charge points, 3x25A) the new MX-30 will still be able to do 11 kW.

Having said that, I was initially bummed out because I have a 3-phase Zappi V2 at home which is connected to 3x25A so 17 kW, for future proofing (3x35A would be possible, but at 500/yr extra not worth it). But then again, the difference between 6.6 kW and 11 kW is not that huge, especially for home charging. By the way: on that 6.6 kW: the Mazda is limited to 29A, so it's slightly below 7.4 kW in reality. My Zappi does 5.7 kW by itself since it's 1x25A for the MX-30, but add to that the solar panels and it even goes up to the 6.6 kW total.

So to come back to your point: yes, the old MX-30 which we both have will only charge at 3.7 kW on a 11 kW charger. But the new MX-30 is indeed going to be able to charge at 11 kW because it's a 3-phase car on a 3-phase charger and in this case also the exact same specs (3x16A). And like I said: on a 3x32A charger (22 kW) the new MX-30 will also charge at 11 kW.

Personally, the 11kw capability upgrade is neither here nor there for me. However if the DC charging upgrade turns out to be software based only then that would get from myself.

Yeah, same for me. Nonetheless, it's good that manufacturers do make not of what needs to be improved and they act upon it.

For us the MX-30 is our 2nd car, the first being a 64 kWh Kia, which coincidentally also has a 1-phase charger while later models have a 3-phase charger. For me it wasn't worth paying the thousands of extra over the one I have now, all else being equal. Fast charging for our Kia and its newer model is still identical at 77 kW and that's just fine even on holiday throughout Europe.

And I have to say: the 38 kW on the MX-30 is just fine as well for the type of car it is. I never need to charge it from 10-80% for example, for me it's always just about getting it home. Sometimes that's 20 km, sometimes 60 km, but I hardly need to charge any longer than 10-15 minutes. Of course helped by having a home charger and thus being able to arrive with 5% and simply plugging it in straight away. And since owning the MX-30 since January this year, I only needed to use it a handful of times. But then again... its The Netherlands, I can get from the coast to the German border on a single charge.

My guess is that assuming the battery is the same in the original and 2022 models then the DC charge rate is just a software setting.
But if the newer models uses a battery with a higher charge C rate then, it’s a no go ☹
