    I mean it's a thread talking about the exact issue I was having, I'm not sure how that makes it random?

    Apologies if I came across harsh - not intended that way. Was just responding to the suggestion that it "seems like it's just kind of the way it is?" being based on a 5 year old thread. I thought if it was a common problem/complaint, I think you would readily find more recent complaints online, even here on Boards on one of the dedicated Tesla threads.

    As I said, I don't recall this ever being an issue in those threads, but might be worth asking the question in the dedicated Supercharger thread.

    Do all phev charge the battery a little after they park up?

    I have noticed that if I exhaust the battery down to empty, drive on ICE for a while then park up, if I leave car and come back later, it could be at 3 or 4%.



  • Registered Users, Registered Users 2 Posts: 2,467 ✭✭✭Ivefoundgod


    My tiguain doesn't anyway and even warns you when you turn it on that there is no charge left. Even at that thought it will switch to battery mode in stop/start traffic, i assume something like a mild hybrid would do but i've never had one of those.

    I'm guessing the cells were balancing when you turned it off low when you got back the lowest power cell had been topped up by the others slightly

    Free lectric☺️, a true self charging hybrid 😏

    It does happen though, wonder what the explanation is?



  • Registered Users, Registered Users 2 Posts: 10,033 ✭✭✭✭CoBo55


    The only explanation I can think of is that the car is charging the battery a small bit when running on petrol. I did have that option on the Superb but it was heavy on petrol so I rarely used it.



  • Registered Users, Registered Users 2 Posts: 13,005 ✭✭✭✭the_amazing_raisin


    Bottom balancing the battery. The SoC will drop to zero when one of the cells drops below 2.5V or something

    The remaining cells will be at a higher voltage so the BMS will start balancing the cells

    This will recharge the lowest cell so the BMS will think there's some useable charge in the battery

    I think BMW PHEVs will use the petrol engine to charge the battery when in sport mode. It'll charge up to around 20% so you can then use the petrol and electric motor combined

    Yeah, it sucks. If only BMW would have allowed for max torque from the electric motor at least from zero, the i PHEV cars that are combined petrol and electric would have been winners. Now they are losers. I love the i8. 0-60 time of just 3.7s, which is Ferrari quick, convinced me to buy but in real life it is rather slow compared to really fast EVs. I know I am spoilt that way, but a combustion car, even the fastest ever combustion car ever in the world, would never excite me again.

    And I would urge anyone out there not to buy a new combustion performance car either because soon everyone else will find out too and their value will drop



  • Registered Users, Registered Users 2 Posts: 1,653 ✭✭✭yer man!


    Has anyone here used the Gridserve network over in the UK?

    Used it last week next to Gatwick, got 60kw/h of electricity into the rental car before dropping back, tapped using phone and it charged the £1 hold but it still hasn’t charged me for the actual electricity.



  • Registered Users, Registered Users 2 Posts: 13,005 ✭✭✭✭the_amazing_raisin


    Fill er up and run! 😂

    Same thing happens at Ionity City North sometimes, seems to take a while to take the money from your account

    I've never been 100% sure but I think the chargers try to sync at the end of each charging session, which occasionally fails due to dodgy internet connections. This is why your holding charge is still there but you haven't been charged for the electricity you took

    I'm guessing they're also recording the sessions to a local audit log which then syncs later when the connection is restored

    At some point some backend software passes the audit logs for any sessions that weren't reported as closed and when there is one (like your case) then it'll bill the session accordingly

    To be clear, I've no knowledge of how these chargers work, I'm just guessing based on some knowledge of vaguely similar software

    ^^Similar thing happened to ms jou almost 2 years ago. Car charged at Ikea car park. Have no clue what network the charger belongs to, but, until now, they did not take money from her account.



  • Registered Users, Registered Users 2 Posts: 9,732 ✭✭✭CMOTDibbler


    Had similar with a newly opened EasyGo charger a few weeks ago. Charged on it just to check that it was actually operational and the app tells me that the cost was €0.00. Waiting for the other shoe to drop. 😁



  • Registered Users, Registered Users 2 Posts: 1,656 ✭✭✭deepimpact


    I charged on an EasyGo charger in Lidl Charleville last year and the same thing happened. Charge was about 25kWh.

    They never registered the charge until about 2 weeks afterwards and I got the notification that the account was charged.



  • Registered Users, Registered Users 2 Posts: 1,509 ✭✭✭jlang


    Seems to quite regularly be a week or two later before the email detailing the charge comes through. We don't charge away from home that often so it's usually clear which session is which but if you were to charge regularly at different sites, sorting the receipts out after the fact must be a nuisance.



  • Registered Users, Registered Users 2 Posts: 9,732 ✭✭✭CMOTDibbler


    The apps keep a record of your charging sessions and costs.



  • Registered Users, Registered Users 2 Posts: 1,510 ✭✭✭cannco253


    I've used Ionity Athlone a fair bit over the last 2 months, ID.4 plug and charge works great there.

    I saw an email from VW/We Charge that they now bill you the following month for any charging sessions, so the days of late billing are over for Ionity anyway…



  • Registered Users, Registered Users 2 Posts: 1,817 ✭✭✭funnyname


    We have an MG ZS for 4 months, 7,000km clocked up but only ever charged at home by zappi. Current 100% GOM is giving about 480km.

    We're going to Dublin on Sunday for the All-Ireland final.

    We'll be travelling up the M6, any suggestions as to where to charge en route, we'll be stopping for food in both directions.

    I was thinking the Tesla superchargers in Johnstown or Enfield services.

    Also which services should I sign up to in advance, Ionity, ESB, Tesla, anyone else?



  • Moderators, Society & Culture Moderators Posts: 42,242 Mod ✭✭✭✭Gumbo


    Enfield is open to non Teslas so aim for that.
    download the Tesla app for use.



  • Moderators, Sports Moderators Posts: 19,831 Mod ✭✭✭✭slave1


    You might as well sign up to ESB pay as you go, it's inevitable you will use them at some stage and their infrastructure grows by the week.

    In 7+ years of EV driving I've never used Ionity



  • Registered Users, Registered Users 2 Posts: 16,179 ✭✭✭✭AndyBoBandy


    Tesla Supercharger Enfield all day long… 6 chargers all up to 250kW, and the hotel serve lovely food.

    An inbound top up here gets you in and out of the city comfortably and a top up again on the return trip home will see you through….

    I wouldn’t stop in Enfield services…. Last time I was there I had to wade through piss to get to the toilets… Johnstown House is a lovely hotel with great bar food and clean facilities.



  • Registered Users, Registered Users 2 Posts: 66,650 ✭✭✭✭unkel


    In fairness that is because at first you had EVs, that couldn't use Ionity. And then you had Teslas, that didn't need Ionity 😁



  • Registered Users, Registered Users 2 Posts: 1,817 ✭✭✭funnyname


    Perfect, thanks a million for the suggestions

    Stupid question but I presume my DC connection is compatible with the superchargers? Also what rate of charge (Charging: 1 phase AC: 7.2 kW max. 3 phase AC: 11 kW max. DC: 75/94 kW max (SR/LR)) should I be looking at when connected, it's a LR model so will I get close to the 94kW and after the drive from Clare should the battery be warm enough for optimum speed?



  • Registered Users, Registered Users 2 Posts: 16,179 ✭✭✭✭AndyBoBandy


    V3 Superchargers (Enfield & Athenry, and Cork/sandyford) are CCS2 so fully compatible with your car…

    Look up your cars charging curve on EV database, but as the V3 Superchargers put out 250kW, your car will be the limiting factor, not the charger, so if you arrive with a warm battery and low SoC% you’d see the full 94kW initially.

    The car should be warm enough after that drive, but you’d probably want to be below 20% to see the headline speeds, and the speed will taper down as the battery fills up (charging curve)



  • Registered Users, Registered Users 2 Posts: 16,179 ✭✭✭✭AndyBoBandy


    also, if you are in having food, the car could be well finished charging before you’re finished eating, so make sure to be aware of when it stops charging to move it as Tesla charge €1/min for overstaying…

    ESB will give you a slap on an ass cheek for overstaying, but Tesla will remove your pants and violate you for doing same.

    They do allow you one free transgression before penalising you though.

    Fastned has lots of charging curves but unfortunately not for your model. Here is a link for different MG models

    https://www.fastnedcharging.com/en/brands-overview/mg

    As you can see the charging power is not flat during the charge.

    As to why and what affects it a quite interesting read is here
