Hi all, I know there has been a lot of threads on charging so you’ll have to excuse this old duffer for asking something that might have been asked before. My guess is a certain person will explain my question really quickly & clearly. So, what is the difference between ac & dc charging. I am assuming the granny lead is ac & public chargers are dc. Also what is the highest (kw) charger an owner of mx30 can use. Thanks to all. Paul….

Older MX-30 takes 6,6kW (or 7,2kW?) 1-phase AC-charger and 36kW rapid DC-charger
New 2022 MX-30 can take 11kW three phase AC-charger and 50kW rapid DC-charger

In Finland there was a AC-changer with the car. It takes 1-phase from normal socket and power is 1,8kW.

DC rapid charger connector is CCS on public charger.

Paul, here we go UK, restrictions as laid out in Janne's post

AC
Granny is about 2 - 3 kw per hour
Fast is 7kw home or public - single phase 5 pin cable or 7 pin using only L1
Ultra fast is 11 or 22kw public - needs a 3 phase 7 pin type 2 cable

DC = rapid chargers
All tethered leads on the chargers for safety reasons
40 - 50kw upwards is the base starting point

Hey there, since my MX-30 is the 2022 Makoto, I’m assuming I have a model which can take the three phase charge…

Unfortunately Mazda have only supplied a single phase cable so how can I confirm if my car has the larger capacity rectifier?

Is there any way to see the charging current in the car?

Can you check if the car charger socket has L2 and L3 pins in metal? Similar to L1

If so can you find a local 22kw tethered charger?

The car will indicate how long % charge will take and its a simple calculation from there. No kw rate displayed in the car.

20% = 6.1 = under an hour on 6.6 - 11 = under 30 minutes etc.

All the pins in the car are metal, but all the 22kWh chargers around here are just type2 sockets… and tethered ones are DC.

I’m reluctant to buy a three phase cable if I don’t need one… yes I’m that cheap 😂

It's a bit hit and miss which are tethered 22 or 43kw. Some sites don't tell you they have a tethered option. Moto m5 near Exeter has one type 2 43kw for example...best of luck

P.s love Exeter spend time down there with BT in my working days

We only moved to Exeter a year ago, it’s a bit of a shock having lived in London for 20 years! But yes it’s a pleasant enough part of the country, and since almost all of my work is remote now, there’s no need to be in London all the time paying an extortionate mortgage on a tiny flat, and I have a lovely purpose built office in my garden now to work in!

I’ve bitten the bullet and bought a 22kw 3phase cable. I will report back and confirm the Makoto’s charge capability!

So using my Mazda supplied Single phase charge cable:

1.5kWh delivered in 15min
3.2kWh delivered in 29min

Using my new three phase charge cable:
1.4kWh delivered in 7min

I’m going to try and get a second three phase data point tomorrow, but so far it looks like the Single phase is charging at 6kW and the three phase is charging at 12kw (more likely 11 and the values were too small for accuracy).

But so far it seems if you have a newer MX-30 it is worth getting a three phase cable!


-Edit- Data obtained using a local 22kWh podpoint charger, where I can see the charging data in the app.

So second charge on the three phase:
6.75kWh delivered in 35min (the dashboard said it would take 1 hour), so that is confirmed as approximately 11kWh charge rate on three phase for the 2022 models, but it appears the car’s charge time guesstimator hasn’t been updated to be aware of the faster rate!

So 10kW max. Don't forget that if you couple it to, say, a 22kkW charger, the input will be higher to fund the losses. Probably 10% or so but you might like to evaluate.
I’ll be doing more testing but, since three phase charging is twice the rate of single phase, I’m actually quite happy with that. An unexpected bonus for the delay in receiving the vehicle.

So I tried a 50kW DC charger today:
4.9kWh was delivered in 19min. (66% -> 80%)

So 15.5kW was the charge rate? That seems a little low, as the 2022 MX-30 is supposed to be able charge at 50kW on DC.

The issue can be that the dc charger is not delivering full rate in the first place. Because we don't have that displayed we have to use instant calcs as soon as it is plugged in, based on existing % to required % time displayed to covert to kw required, based on 1% being .305kw, 3.05 being 10% etc to understand what is actually being delivered. A real pain...the car should have a kw delivered rate indicator!!!

50 is probably 46kw delivered so it should give 14 % (about 4.5kw) in about just over 6 minutes roughly if my brain is working correctly today
