Why not use a Leaf granny cable all the time?

    Given that granny cables are supplied with new cars in the U.K. where I presume Nissan intend them to be used why would I not use this all the time rather than pay the best part of €1000 to have a home charge point installed?

    Probably an obvious answer but for the moment it escapes me!

    How long is "too long" for this to be the main method of charging if having a home charge point installed takes a while?

    Also, could someone point me in the direction of the EXACT unteathered home charger I need for a 3.3kw Leaf, and the correct necessary cable of course. Is Type 2 the one I need. Oh, and what's "multimode" I see listed on some of the Rolec models?

    A granny cable will add 10km per hour of charging. I use mine daily for the past 12 months.

    A dedicated charge point will add 16 km per hour of charging.

    The LEAF needs a Type 1 plug.
    There are lots of opinions but a Type 1 tethered charger (cable permanently attached) is very convenient for home charging as you don't have to put a wet cable in your boot!
    You could also have a weatherproof outdoor socket fitted and carry on using your granny lead for <€1000.

    eh...have you looked at the time it takes to charge via granny cable?


    My UK sourced Leaf came with a T1/T2 cable only...but then it has 6.6kW charging. I thought I'd need a granny cable but firstly, they're a horrendous price and secondly, they take forever to charge. Plan your trip and you won't need one - or if you do, either get a nissan warranty flatbed or insurance covered flatbed.

    I use scp's / home charging every single day - so I couldn't do without the T1/T2. You may not always be able to access an FCP as there are so few of them.

    Up to personal preference - but i'm not bothered about going untethered. Separate cable is needed for SCP#s anyway...and it's much easier to upgrade chargepoint when the time comes. I don't see going to or from the boot with the cable as such a big deal. Chargepoint also looks neater without it.


  • Registered Users, Registered Users 2 Posts: 1,190 ✭✭✭quenching


    So, if I want to plug into a home charge point and public charge points (not Rapid) I need to get a cable with a Type 1 plug (for car socket) to a Type 2 plug (public charger socket) and a home charge point with a Type 2 socket. And all Rapid Chargers have teathered CHAdeMO cables.

    If I get a Type 1 to Type 1 cable it won't work with with public charge points, correct?


  • Registered Users, Registered Users 2 Posts: 122 ✭✭sgalvin


    Correct.
    Public charging is TYPE 2 sockets and non thethered home chargers are too.

    You don't need a T1-T1 lead. I don't think I've seen one.

    Rapid chargers for the leaf are tethered Chademo plugs.
    Other cars (Zoe) do use a Type 2 for slow/standard/rapid charging.

    Chauffe, Marcel, chauffe!


    I'd rather have 1 granny cable plus a 20m extension in the boot of my car than 1000 slow charge points across the country.

    No granny cable = no destination charging

    Thankfully the Ioniq comes with a granny cable as standard. I would have hated to spend several hundred quid on one, but I would have bought one.

    Thanks for clearing that up, I'm getting a UK car with a granny cable so that'll have to do until I organise a home charge point. Most days the car won't be driven more than about 40kms, so 8 hours of night rate charging on the granny cable for a while should be fine.


  • Registered Users, Registered Users 2 Posts: 8,035 ✭✭✭goz83


    Having a home charge point installed means you can charge the car faster and it's a lot more convenient. The granny cable I see as more of an emergency cable. I used it for about a week while waiting for the home cp to be installed and while it did charge the car fully overnight, it was just a hassle. It's bucketing rain oitside right now. I plugged in the Leaf a few minutes ago with my tethered home cp. I probably wouldn't have bothered if I had to take a cable out of the boot.

    It doesn't have to cost you 'the best part of 1k euro to install! - not if you're savvy about it.

    You're driving an Ioniq - if you were driving a Leaf, you may express the same view but I doubt you'd express it to the same extent. Those chargepoints dont cost anything like the FCP's. Secondly, there was no Ioniq when these were rolled out.

    I use an SCP every working day of the week - via a Leaf with 6.6 obc. I know you dislike this option also - but if you had to buy a Leaf, then it remains to be seen if you'd have the same belief.
    Personally, I wouldn't buy a (24kW) Leaf without 6.6kW charging.

    I'd say the main reason to install a wall mount EVSE is convenience as there is less faffing about with wet, dirty cables when you have the wall mount EVSE.

    The granny charger is waterproof but it still has a normal indoor 3-pin plug on the end so you have to ensure that wherever you plug it in is also waterproof. If you have a waterproof outdoor socket in the right place for the car then all is good but if you have to use extension leads (which will have to be covered from rain) or putting the cable out through an open window its a PITA.

    The granny charger charges at 10A, the wall mount EVSE can do 16A or 32A so obviously they are faster and they are also marginally more efficient.

    A granny charger will add about 2kWh to the battery every hour. On a 24kWh Leaf(22kWh usable) it will take 11hrs to fully charge and then it also needs a few hours beyond that to do cell balancing. So, more often that not, you will not be able to do all of that inside the 8hr night rate so the wall mount EVSE is worth getting (just don't pay €1000 for it... €600 would be about right, cheaper again if you buy 2nd hand)


    Bottomline you can use the granny charger for as long as you like. It won't do any damage. You just need to make sure the plug is not exposed to rain/damp. Long term the wall mount EVSE is the way to go.



    Here is an example untethered type 2 that will work with the Leaf assuming you have a type 2 to type 1 cable:

    If the car comes with a granny, get a proper charge point installed for cheap. For example => LINK

    Then see if you really need the granny. If you don't flog it - they're ridiculously expensive - it will pay for your home install and then some.

    Thanks for that, I'll probably hang on to the granny cable as a safety net, but I'll follow up on the Chargemaster Type 2 you linked to. Just need to find a friendly electrician to install it.

    Granny cable is an insurance policy, so don't sell it! You can use it full time too.

    If you have a 32a charge point and can get it installed for reasonable money it's very handy, especially if tethered (i.e. built in cable). You can charge a 6.6kw Leaf at home in around 3 hours. Tethered has the advantage of not having to dig a cable out of the boot or coil one up when finished, especially if it's wet.


  • Registered Users, Registered Users 2 Posts: 1,087 ✭✭✭isnottheword


    Up to you. However, once you get used to EV driving - knowing it's limits and planning journeys, you may find that you don't need the granny cable and don't need it taking up space in the boot.

    If you get to that point, remember what that darned thing is worth - as they're ridiculously expensive. If I end up buying another Leaf that comes with granny cable, I'll be flogging it.


  • Registered Users, Registered Users 2 Posts: 122 ✭✭sgalvin


    I agree the price is rediculous for what is a mass pruduced relatively simple item.
    Same for the home charge points for that matter.

    The cars should all support a mode1 10amp charge with a €50 cable to cover emergency use.

    Would I pay €600 for one. No way!
    Would I sell mine for €100-150. Em No.

    I find that my leaf charges from single digits to 100% and finished balancing(and all blue lights off) in 10-11 hours.
    I don't have night rate so that isnt really impacting me anyway.

    If you have a 3.3 leaf it will charge in 8-9 hours from a home CP, so for that 1-2 extra hours it's not worth it to me to pay for a dedicated CP.

    However if you have a 6.6 leaf (like I do) it would be worth it as you could charge fully at home in 3-4 hours. Possible even to charge 2 leafs at night rate, with timers etc.

    I use the granny cable as part of planning journeys.
    A 200 km each way trip to see inlaws is a lot better and more manageable if you can use a granny cable overnight at the inlaws' place

    That was exactly my reasoning so I went with just the granny charger and it's perfect. Glad I didn't spent the extra money for the other charger.

    I did talk to several people who have only been charging.using the granny cable for up to 5 years thiugh before deciding it would do the trick.

    Whatever works for you :-)

    I thought I would pick one up at some stage once I had bought my Leaf - and was offered one by a work colleague. However, by that stage, I really couldn't see the benefit (vs. the cost of the thing).


  • Registered Users, Registered Users 2 Posts: 987 ✭✭✭oinkely


    We use the granny cable to charge one of the leafs every night, while the other charges on the rolec. The 3.3 charger one uses the granny lead and charges to full within the night rate every night. We would usually be charging from between 30 and 40% up to 100%. Wouldn't be without the granny cable, as it gets used every weekend when we are at our caravan also. Horses for courses, but definitely worth having IMO. Especially as they come with pretty much every leaf you buy in the UK.

    If you're in Dublin I can give you the name of a friendly electrician. He installed an untethered chargemaster for much less than I was quoted by one of the ev companies. I bought the unit separately for a good price too.

    I'm fairly sure this is what I need for a 3.3kw Nissan Leaf to charge at home and at public charge points, I've picked the 32a versions to allow for future car changes:

    I'm struggling to find anywhere that offer better value (I'm not making one myself!) but I'd be delighted if someone points out better value. I've a local electrician happy to do it, €49 callout including the first hours labour plus €25 per hour after, reckons 3 hours at most.


  • Registered Users, Registered Users 2 Posts: 12,186 ✭✭✭✭KCross


    They look correct to me. I used them as well for the charge point. The cable came with my car.
    Reasonable prices on the electrician as well. Should be quicker than 3hrs unless its an awkward job somehow.

    FYI: If you want to monitor what the car is costing you you can add a kWh meter to the charger before you add it to your cart. I find it useful but it is dead money of course.

    Why do you need a cable? I've never heard of a Leaf being sold without one. The only time to buy another would be to buy a huge length 10m+

    Thats hit and miss. Some come with both cables but its typically the 6.6kW ones that have both. I think you are looking at a 3.3kW so most likely a granny cable only, as you said.

    There was a time that UK leafs were only sold with the granny cable and the type1-type2 cable was an optional extra.

    It is possible that the owner paid for the option but subsequently retained it for his next type1 EV.

    Very early Gen 1 Leafs? Hmmm first I've heard of that. Either way there's no doubt they'd have picked up a cable at some point and really should be selling it included.

    Not sure when the crossover happened but it is mentioned online a lot.
    My UK leaf came with a type1-2 cable and granny cable. If I'm selling it I will keep the granny cable but let the type1-2 cable go with it. Had to pay 370 quid for a 10 metre granny cable as I broke the connector on my first one :mad:. Still looked fine but the connections got into water during a storm as I left it hanging outside. Mea Culpa. As a plus side I also got a CEE plug adapter so i can really charge anywhere now.


  • Registered Users, Registered Users 2 Posts: 2,942 ✭✭✭stesaurus


    Yeah keep the granny, that's completely fair as it's usually optional on the Leaf. Other models have it as standard so I'll be passing mine on. I have a CEE to UK 3 Pin socket adapter in my car also, handy to have but haven't used it yet.

    If you go with Leaf 2 or Ioniq etc. as your next car then it probably won't work. Isn't Leaf 2 switching to type 2 for AC charging

    I've seen photos of it with a type2 slot for AC alright. I won't be moving to leaf2 anyway. My next EV if it's not a tesla may be a nearly new Ioniq or ZE40Q90 Zoe. There are type1 to type2 adapters, I would get one of those cheaper than a new granny cable I suppose.

    I only paid £14 for the CEE adapter so I thought better to be prepared. A lot of places that dont have charging facilities - hotels etc -may have outdoor CEE plugs.

    Strange choice , a new tesla or a 2nd hand Ioniq !

    Ps : CEE ( actually CEE 17) is deprecated , the standard. Is IEC 60309 , or often called Commandi sockets in the uk after the Mk trade name

    Yes it depends on funds in 12-18-24 months when I get rid of the leaf. I was considering a used tesla - Probably an S85 given the values - versus a used Zoe/Ioniq.

    Surely a new leaf will be a better deal financially then a nearly new current model Ioniq

    As for an 2nd hand S86, surely that will be mega money

    A new leaf depending on price point, yes it could be. However I expect there to be minimal difference in the range and the Ioniq to charge much quicker at an FCP, tipping the balance in the Ioniq's favour. A new car is never as good a financial deal as a 12-18 month old ex demo.

    An S85E, the lowest spec model, currently are listed at around ?40-45k in the UK. Down approx 15% YoY. Continuing that depreciation I expect that they should be in the ballpark of ?30-35k in approx 18 months. They are not comparable cars price wise, one is luxury and one is a white goods. Its like comparing an Izuzu Trooper to a Range Rover HSE. Both are 4x4 but one is a white good and one is a luxury.

    I don't expect there will be much difference in 2018 leaf chsrge rates and Ioniq , in reality they are all using the same battery tech

    At present leaf has a serious advantage in the number of fast charge points and this won't change soon either

    Of course these fast charge points top out at 50 kW , do not much point at present having huge chsrge acceptance rates

    I suspect Nissan will certainly leapfrog the current Ioniq but probably not by a huge amount , but enough to ensure the majority of current leaf owners consider the 2018 leaf , especially those on PCPs.

    Expecting huge leapfrogs in range isnt going to happen with the current pricing projections of lithium battery production

    Ps : as a former owner of 5 HSE RRs , you never want to buy an old one. !!!!

    They top out at ~70kW in some instances. I saw on plugshare a photo of an Ioniq charging at 67kW at Naas for instance. If you can take 100kW for instance, you will charge quicker at a 50kW post than a car that maxes out (like my leaf for instance) at 50kW. Less tapering. My leaf takes an age above 60% SOC.

    I'm lucky that I bought my leaf outright and am not influenced by PCP. My experience with Nissan and the leaf in general would not lead me to buy another one. I'm not too fond of Renault either after the way they treated the Fluence owners. Hence my preference for an Ioniq. But I would still consider a Zoe as it's the first car that I could drive as an ICE car, the range is long enough to consider it as a "tank" as opposed to a range like most EVs now outside of tesla.

    All I can say is my experience with the 30 kWh leaf has been excelkabt and I'd be predisposed to another leaf. I found the Ioniq cramped compared to the leaf

    Your comment really charging speeds is not correct , charge rates on Lil are fairly consistent across the chemistry. What differs is what manufacturers feel is " safe " for the longevity of the battery

    Nissan for example are way way less conservative on the 30kwh leaf
    At 90% charge yesterday on the dbt as glasnevin I was still charging at 56A at 400V or > 20 KW

    With greater variety of chargers compared to CCS and plenty fast charging there is little in it between the current Ioniq and the 30 kWh leaf in reality

    The Ioniq charge rate max is 70Kw on European Ioniqs

    and from a dutch you tube on the Ioniq and CCS charging

    "A charging session starting from about 10% of capacity, filling up to 94% (fast charging above 94% is not available), took about 30 minutes. Bjørn notes for the last 15%, charging maxed out at about 20+ kW."

    the 20 Kw is not dissimilar to the 30 kWh leaf in that zone , i.e. from 85% onwards

    Ok I should have said actual achievable charging speeds, not the technically possible ones. It's all well and good having a battery capable of charging 0-99 at 50kW but if it's BMS limited by the OEM to taper from 40% SOC that's worth SFA. And following actual charging speed an Ioniq will charge higher for longer than your 30kWh leaf, which in turn will charge a lot higher for a lot longer than my ancient 24kWh leaf!

    The anecdotal feedback is the actual charge times are not that much different , certainly in my trial, I couldnt see much of a difference ( i.e. if anything it was a difference of a minute or two )

    Also the Leaf is much faster on some models of FCP then others , in particular its fast on DBTs.

    IN reality the greater ability of the Ioniq is rather lost in ireland given the ratings of the FCP

    its also rather ridiculous making comparisons at this level of minuteness

    Look at the photo on plugshare of an Ioniq charging above 65kW at Naas.
    Your leaf can charge at 50 but not above.
    It's hardly minute, 17kW is a lot of juice to forego. MadLad's test of the Ioniq reported 15 minutes for a full charge beyond 80% at an fcp. You can't surely claim minute difference between an ioniq and your leaf surely.

    I find my leaf to be slower on DBT than the efacec units, fwiw.

    can you point me too that

    I test charged the Ioniq, , I didnt track the power , merely because I cant select FCPs by power , I just use the one that is on my journey , in my test 30% to 80% in the Ioniq, I didnt notice it being that much faster ( as in a noticeable amount of time)

    i confess , that I didnt unlike i normally do make a lot of notes, mainly because I didnt see a whole lot of difference

    ( Nor would I expect a whole lot of difference either given its the same battery in the Ioniq , at 30.4 kWh as is typical in the 30 kWh Leaf)

    to make this comparison , youd need detailed data and charge profiles too , mine was just based on my waiting around , buying a coffee and drinking it, I didnt see much gain with the Ioniq, ( yes there was a small gain , but not a material difference )

    The main gain with the Ioniq is for a given distance the charge energy that was to be replaced is less then the leaf and that leads to shorter times at the FCP

    It seems that some 50kW chargers can deliver 65kW!
