Any point in getting home EV charger?

    I'm about to purchase a plug-in hybrid which has an EV range of 70kms. Generally, that would do me for the week. However, approx once a month, I do a round trip of 300kms. This trip would involve an overnight stay

    My question is, does it make any sense to install an EV charger in my home, or should I stick with the granny cable it comes with? I'm being quoted between €1.100 and €1.500 to install a charger. I'm retired and there's a 2nd car available, so a 6 hour charge time, once a week, wouldn't be much of an inconvenience. I would be able to use the granny cable during my overnight stay too. I have solar panels if that's a consideration

    All thoughts appreciated

    We've been running a full EV using just the granny charger since March. We also have solar, without a storage battery just yet. This is coming soon - I'm in the process of upgrading the setup I have at the house as I run a business from home and need more power than I used to anyway, plus we're about to change to a day/night tariff - but here's how things have been working for us.

    The car is often at home during the day, so it just gets plugged in to trickle charge - especially whenever there's enough sunshine to generate a surplus from the panels (not as much at this time of year!). Up to 2-3 weeks ago, I've often been able to charge the car for free just from the solar excess - if I don't need a lot of range in a hurry, I can slow the charge rate on the granny charger to just 6 amps, which translates to adding about 5km of range in an hour. If I want it to charge faster than that, or if it's particularly bright, with the touch of a button I can adjust it to 8 amps, 10 amps or 13 amps - the latter will add about 16km in an hour. On the occasions when we know we're going on a long trip, we just leave it to charge all day or else overnight, depending on how much range the car needs to add. We only rarely need to use public chargers, even though one of the longer trips we do regularly is 300km each way, as we can trickle charge overnight when we get there.

    Your use case seems to involve doing slightly less day-to-day driving than we do, and your regular longer trips are half the distance of ours if not less. If your car also spends a lot of its time on the driveway at home, and if you have a suitable outdoor 3-pin socket (or can get one fitted), I think you'd be fine with just a granny charger, as you'd be able to fully charge your car's battery in under 5 hours. Depending on the size of your solar array, if the car is parked on the driveway during daylight hours you may even be able to charge it from the sun for free. In your shoes, I'd save the money and not bother with the home charger.

    Dont see much need for the home charge point in that case.



  • Registered Users, Registered Users 2 Posts: 3,329 ✭✭✭Buffman


    There's no need to blow €1k+ in that scenario OP, you'll be perfectly fine with the granny charger long term as long as it's plugged into a suitable socket.

    The below is a general 'signature' and not part of any post:

    FYI, if you move to a 'smart' meter electricity plan, you CAN'T move back to a non-smart plan.

    You don't have to take a 'smart' meter if you don't want one, opt-out is available.

    Buy drinks in 3L or bigger plastic bottles or glass bottles or cartons to avoid the DRS fee.

    I'll weigh in behind the posters above, no need for a dedicated charger for you.

    Full EV might take too long but PHEV will be fully charged overnight



  • Registered Users, Registered Users 2 Posts: 3,222 ✭✭✭Eggs For Dinner


    Thanks everyone, you've confirmed what I was thinking

    Buffman, can I ask what you mean by 'suitable socket'. I have an outdoor socket mounted on the wall of the house, but might need to run an extension cable to it. If that is not appropriate, I can always run the granny cable in through a window into one of the internal house sockets

    Dont plug into an extension lead. Smell of burning plastic the next morning the last time I done that.



  • Registered Users, Registered Users 2 Posts: 7,399 ✭✭✭KCross


    The granny cable will be pulling 10 amps for hours on end. Thats close to the max that a standard 13amp socket can handle. If the socket is old or worn it could overheat. Think of the granny charger as like having your kettle turned on and heating constantly…. thats the draw the granny cable will have. If the socket, or cable feeding it, are worn in any way it will be a problem.

    You should not use extension leads.

    You should regularly check that the socket and granny plug do not get hot, particularly the first few times you use it.

    If in doubt get an electrician to check it and maybe replace the socket if it is old.



  • Registered Users, Registered Users 2, Paid Member Posts: 5,272 ✭✭✭...Ghost...


    I would agree with the above advice. You'll do fine with a granny charger as long as the socket is good and you don't start using extension leads.

    The benefit of the dedicated charger is speed and convenience. They are safer too. You can get some of the convenience by leaving the granny charger plugged in. Believe me when I say it is no fun digging into the boot on a cold, rainy night looking for the granny charger.

    By suitable I mean a properly installed (correct cable size) and good quality socket.

    Long term use of an extension lead can result in overheating and damage, I've seen examples of melted plugs and sockets.

    As well as that, it will get very boring very quickly running extension leads or cables in and out of windows on a long term basis.

    If you're planning on living with a granny charger long term, I'd recommend either get one with a cable long enough to reach the car or install another outdoor socket closer to the car.

    I mounted my charger semi-permanent to the wall and it was far more convenient than setting it up each time.

    Not sure what car you are buying, but 70km of range is probably highly unlikely. Especially with the heating on and during cold weather.

    While I agree there’s no need for a charge point but I’d just like to state that they can be got significantly cheaper. €699 for example supplied and fitted after grant.



  • Registered Users, Registered Users 2 Posts: 3,222 ✭✭✭Eggs For Dinner


    Thanks again everyone, valuable information to consider.

    User1998, the car is a Hyundai Tucson plug-in hybrid. While I intend using the EV mode for my (low) daily usage, I've no issue relying on the ICE if conditions to charge it are not favourable.



  • Registered Users, Registered Users 2 Posts: 3,222 ✭✭✭Eggs For Dinner


    Thanks Gumbo. Can I ask who is installing them at that figure?. On a technical issue, does the EV charger have to be wired directly to the fuseboard. My fuseboard is in a very difficult location from where I would want ro mount it



  • Registered Users, Registered Users 2 Posts: 6,637 ✭✭✭MojoMaker


    If there is travel distance form chargepoint back to fuseboard there is usually a modest extra on the price to account for the greater cabling quantity and labour time. Not a huge deal. The team that comes out to you should factor that into the quote you get.

    Not to burst your bubble, but we have recently got a 232 Hyundai Santa Fe phev, so same engine and battery etc as a Tucson all be it a bigger car.

    You can't force the car to run on electric outright, you can select it but it will do its own thing.

    Turn the cabin heating on/up and the engine kicks in as it does not have an electric heater...,.. it uses the ICE coolant system to heat the car......

    It does about 50km in electric mode at best and it reserves about 3kw of the battery capacity to maintain the battery at all times, so technically you can't use the full 13.8kw battery it says you have at your disposal.

    We use a granny charger and with it set to reduced capacity to be on the safe side with overloading, it takes about 8hrs to charge fully from empty(it will still show quarter tank of battery left at this point)



  • Registered Users, Registered Users 2 Posts: 3,222 ✭✭✭Eggs For Dinner


    Thanks for the information, which I wasn't aware of. Very helpful. No bubble has been burst, as the EV aspect is not the reason I chose the car. It's a nice add-on to the most economical version of the car I wanted for other reasons (automatic, comfortable driving height, tech, looks, spacious). I'm an EV sceptic and the other car in the houshold is ICE, so I'll live with a mix of the granny charger and public charging to see how I get on. If they prove too inconvenient, I'll consider a home charger. Thanks again

    My neighbour has a PHEV and she just got an electrician to install an outdoor socket like this one.

  • Registered Users, Registered Users 2 Posts: 3,222 ✭✭✭Eggs For Dinner


    Thanks, I have similar at the back of the house and posters above cautioned me against running an extension cable from it to the car. Getting one fitted to the front for a granny cable is one option.



  • Registered Users, Registered Users 2, Paid Member Posts: 3,009 ✭✭✭hold my beer


    What are you sceptical about in relation to EVs? They're great, me and the OH both have one.

    Not opening that can of worms.😄. Let's just say I would have similar reasons to those expressed on this forum many times previously



  • Registered Users, Registered Users 2, Paid Member Posts: 3,009 ✭✭✭hold my beer


    The only thing I've ever read on here is people talkin about range (a non issue). What else could you be sceptical about



  • Registered Users, Registered Users 2 Posts: 6,637 ✭✭✭MojoMaker




  • Registered Users, Registered Users 2 Posts: 2,273 ✭✭✭Paul Kiernan


    If you're going to pay a RECI to fit a socket then consider one like this -

    https://www.screwfix.ie/p/mk-32a-2p-e-surface-outlet-200-250v/691jr

    It will support a full plug-in 32a 7.2kw EV charger and give you about 4 times the charging speed.



  • Registered Users, Registered Users 2 Posts: 3,222 ✭✭✭Eggs For Dinner


    I methodically research every major decision I make. Let's just say that, (for me at this moment in time), it's not the right path for financial, practical and ethical reasons. ICE is not ideal but I believe it to be slightly better for each heading.

    Thanks everyone for the advice, it's been a great insight



  • Registered Users, Registered Users 2, Paid Member Posts: 5,272 ✭✭✭...Ghost...


    Only you dan know what works for you. I'm a natural skeptic myself. I research the cràp out of everything too. I was months going back and forth on petrol, PHEV and EV. EV made the most sense as my primary car, but I really liked the outlander PHEV. There were a lot of bar stool experts who had zero experience or knowledge on EVs, but endless opinions and reasons why I should buy a Diesel despite being a sub 10k a year driver who averaged 30km per day.

    In the end, my head won the fight and in 2017 I bought a 3 yro Nissan Leaf from the UK. Loved it. Cost pennies to run. A few weeks later, our second car was sold and we bought another 5 yro Leaf (2012 model which my FiL now owns). I moved to a Tesla Model 3 in 2022 as my first new car and then a Model Y a few months ago. I stopped thinking about range after buying the Tesla.

    We are an EV household. I have a Model Y. My OH has a Model S recently purchased. Our son owns the 40kWh Leaf I bought last year and I bought a 2015 Leaf last week that my daughter will be driving in the year when she as her license.

    Good luck with your purchase.

    Thanks Ghost. As you suggest, one size does not fit all



  • Registered Users, Registered Users 2 Posts: 6,637 ✭✭✭MojoMaker


    That's 4 sizes I think though.



  • Subscribers Posts: 32,893 ✭✭✭✭5starpool


    And a maximum regular (once a month) journey of 300km means that there are lots of EVs that won't break a sweat doing that range, so almost all charging could be done at home for a fraction of the cost of buying petrol/diesel. If people regularly do long journeys to areas that aren't well served by public charging then I get the reticence. Otherwise, I don't, and it's all 'in the head' stuff that doesn't hold up on closer inspection.

    Well, isn't the issue that the OP is nervous of EV depreciation?

    I mean, that is the financial dimension, right?
