    Hello,

    First let me introduce myself, my name is Henrique from Lisbon, Portugal. This past Monday I received my Renault Zoe R90 Bose. I´m really impressed with the car but with the charging speed using the renault supplied “granny” cable..not so much.
    I also got the fast charging cable but I am yet to try that and we´ll have to wait a couple of weeks (we need a certain access card to use public charging stations and it takes 2 weeks to deliver).
    I have limited eletrical knowledge so please excuse any nonsense on my part.
    The cable reads 16 amps with dedicated outlet and 13 amps without it. I have it plugged to a 16 amp fused outlet and that to a 16 amp dedicated breaker (just for that plug).
    Charge at the moment for 40% discharge is around 14 hours, which means little over 1kw per hour charging or 5 amps of current.
    Any idea why it wouldn´t charge at the full 10 amps?? Many thanks,
    Regards,

    Henrique

    The predicted charge time on a granny cable is always very pessimistic. I suspect you’ll find that it will charge significantly faster than that.

    Also, unless you have a special socket (with a magnet in it), the Schuko granny lead will only charge at the lower rate.

    Actually the prediction has been really accurate. From my understanding the special socket you refer allows charging at 16 amps, still without it I should be able to get the full 10 amps instead of the 5 amps I´m getting at the moment.. Checked other eletrical sockets and same result.

    Hi Henrique
    Welcome to the forum.
    I’m a little surprised at the 5A figure. I don’t have an R40 and I have a UK version of the “Granny Cable” which we use all the time. But it charges at 10A nominal from 230 V and the information we were given is that the 2015 Zoe won’t charge at less than 6A. I wouldn’t have expected the R40 to charge at a lower rate, although I would expect it to take longer to charge a battery nearly twice as big as the one I have.

    As the battery gets close to fully charged the charge rate drops and the time taken to balance the battery varies enormously. Temperature has a big impact on both charge time and capacity (as estimated in range).

    Hope you enjoy the car. We found the car very good and the dealer not very good. Not sure if we replace our Zoe with a Zoe R40 or a hybrid.

    Good luck
    Fred

    Hi Fred,

    As a car it´s great! my daily commute is quite mixed, 10 miles B roads average speed around 35/45 mph then 10 miles motorway usually around 75 mph and then 5 miles stop&go traffi each way so around 50 miles

    On average i´ve been using 25% of the battery for the dailly commute which is fantastic. Car´s really well equiped drives well and I have a range of 310km @ the moment @ 100% charge.

    Is is indeed charging at that extremely low rate from 83% do full charge around 4h30 min..

    Can´t really figure why. I´ve got a free charging station from Renault but I will save that for my next house since current is a rented property.
    With regards to hybrids we had a look at the Mitsubushi outlander and it´s a great car but as long as you don´t need such a big car daily I think the smallest (motorway able in my case) pure eletric turns out the cheapest in the long run. I have a Peugeot 806 for long motorway journeys.
    I´m quite sure that even in the UK (with more expensive car tax and insurance) it is still cheaper (both fuel and maintenance) to have two cars rather than a compromise such an Outlander.

    Cheers,

    Henrique

    Hi Henrique
    The financial case hasn’t been made yet because I don’t have costs for the options. I don’t think PCP offers like they were offering on the Zoe in 2015 will be repeated, and if the interest rates are significantly higher PCP may not be good value. Its the spreadsheet prediction of cost of ownership which will form part of the argument.

    My wife loves the electric drive characteristic and as our regular daily round is well within 30 miles its only when we go away from home and off the motorway network that range becomes a problem. A Mitsubishi Outlander would be overkill given that we don’t need 4 wheel drive or the size. At present UK prices for long range electrics are not much different to PHEV hybrids. A Kia Niro PHEV or Hyundai Ioniq PHEV is closer to our needs. There are alternatives of course.

    Cheers

    Fred
