    Has anyone actually had 50kW from an Ecotricity CCS charger? I have done several charges now (from varying SoH) and never seen quicker than 34kW, Ecotricity say it is the car that is lowering the rate, would like to know that someone has seen the 50kW before I start checking that route.

    I've used 3 different EH rapids to charge my Ioniq, Best I've seen is 36kW

    They are all limited to 43kW to begin with, environmental factors on the car and charger size will also play a part. Anecdotally, I have had 43kW for about 30secs on an i3 before ramping down a bit 'cos it was hot.

    Have you got any records for CHAdeMO or AC @Jack?

    I once saw the display go up to 125A at Beaconsfield, didn't last long and never happened again.

    43kW is the best you'll get, are you really only getting 34kW?

    Here's one charging my car at 42kW but the voltage will go a bit higher when the battery is lower:

    No the PHEV is limited on CHAdeMO to begin with.

    Shame. It would be interesting to compare the same charger on the three standards. 34kW seems awfully slow.

    Also maybe try an ABB charger with the same cars under the same conditions. That would exclude the 'it's the car' theory if you get a much better charge rate.

    I was at 30% state of charge in my 60/75kWh battery and got a max of 34kW at the Leceister Forrest MSA northbound EH pump the other night. Would be getting at least 75kW out of a supercharger at a similar SOC.

    Not really very impressive for a standard supposed to go up to 50kW.

    Edit: yes, this was using a Tesla CHAdeMO adapter

    That was with the CHAdeMO adapter? So adds to my suspicion it I charge point not connector ...

    Add this too then:

    The Nunnery Lane, York Evolt rapid (APT technologies) using my CHAdeMO adapter. I too have never seen more than 36kW from Ecotricity's DBT units.

    Weren't Tesla adaptors limiting charge rates from Chademo chargers to prevent the charger overheating?

    Only DBT units.

    Last Thursday, I watched the rate on and off. It climbed from about 39kW at very low SOC to a bit over 43kW at ~55%: the current stayed about 110A and voltage rose from ~355V to 396V. Above that SOC, the voltage stayed constant but the current declined pretty steadily, so by 83% it was only drawing ~12kW. So, a lot depends on the SOC when you check.

    I think it can go higher: when we had an i3 on test (in much warmer weather), I was impressed by 120A when starting one EH charge, but can't remember the voltage.

    Only photos I took were there, to be honest didn't keep watching it just happened to look a couple of times but what is the point of having a 50kW charger if it wont draw that. The IONIQ is supposed to be able to charge at 100kW!

    Although it looks like no one has had 50kW from CCS, is it the cars or the chargers. I can appreciate as a car gets charged it needs to slow down but I have literally charged form empty and still not got it.

    Unless you are using a non DBT unit it's impossible to get 50kW as they don't pump out that much. They aren't 50kW chargers they are 43kW.

    Anything with Seimens/ABB on the tin nearby? I am willing to bet good money you'd get 50kW from low SOC on one of them.

    I have drawn over 40kw a number of times, especially when my Leaf battery was warm in the first place (eg 6 bars heat). But when the battery is cooler (say 4 bars), it does seem as though 30-something kw is more normal.

    I don't think this is just an EH problem as it is the same on numerous Scottish rapids (mainly Evolt but also sometimes Siemens/ABB).

    *** EDIT *** this refers to Leaf/Chademo not CCS.

    Don't forget it's cold at the moment, as Scotstounpele mentions. Charging is much slower in this single-digit temperatures.
