Slower than expected charging speed

[munkimatt]

Apologies if I'm missing something obvious here, but first EV so I'm probably full of dumb questions.

A bunch of new AMP EV 22w chargers have popped up in town, so we've took the MG down to give it a top up. The cable we have is a 3 phase from EVcables. We've tried two different chargers but both times we seem to be maxing out at under 10kW, between 9.74 and 9.82.

Are we missing doing something in particular to reach higher charging speeds?

The converter in the car is rated at 11kW, so getting around 10kW seems reasonable and ties in with what I've seen other people report here.

Ah, that clears that up. Cheers!

As a silly question from a new owner, is 11kW the max just for untethered assuming tethered ultra fast chargers go much higher?

This is for AC charging only (Long Range models, standard range is limited to 6.6kW) DC is over 100kW again the LR has a higher DC rating than the SR

Yep as said above this is what you would expect after losses. I get about from 22kw AC chargers at work and elsewhere.
Obviously DC chargers give way more kW up to 140 for the LR and actually have less losses by % as they don't have to convert to DC

So far as I know (i.e. researched), the maximum charge rates for short range and long range MG4's are:

Using Granny (residential) charger both Standard and Long Range = 2.3kW (@10A) AC
Using single phase Type 2 cable both Standard and Long Range = 6.6kW AC
Using three phase Type 2 cable, Long Range only = 11kW AC
Using Rapid charger, Standard Range = 117kW DC and Long Range = 135kW DC

Please correct me if I'm wrong, if you have more accurate/up to date data

Long range SE/Trophy has an 11kW internal charger, max I've received is 9.9kW so don't think 11kW is correct that's before losses. In the same way as at home my charge point reports 7.2kW provided and 6.7kW max I've seen received received.
DC LR max in the wild is 142kW higher than the spec states of 135kW

 

[siteguru]

And the SR max. DC charge rate actually reported so far is 87kW. However that may change once the warmer weather arrives.

Thanks for all the data points, folks. I did see my car pulling 6.8kw from our home charger, which by the look of the above reports is about as high as I can expect from a single phase type 2. I haven't tried it on a 3phase type2 yet, but I won't expect more than 10kw. Good to know!
