    Depending on the car, some cars take account of the energy use at standstill as well as in motion.

    I think the point was a GOM event in ICE is a best guess. In fairness it's a non issue in a ICE. But it's more significant in a BEV. So it's interesting but moot comparison. You're not wastefully setting fire to your surplus of energy. It's a different mindset.

    Yeah, I had a car, that I knew I could do at least 30miles with 0 on the range.



  • Moderators, Society & Culture Moderators Posts: 42,016 Mod ✭✭✭✭Gumbo


    Nope, they dynamically change based on current drive style.



  • Registered Users, Registered Users 2, Paid Member Posts: 7,418 ✭✭✭zg3409


    If your doing a daily local school run in cold weather then your tank will only get you 250km, but the GOM says 830km. People think they get 800-1000km from a tank of diesel but for short daily runs the actual real world range is far less. The range to empty will drop eventually to zero, but distance covered won't be 800km. It's more to show that diesel range is often optimistic starting off with a full tank higher reading than you are likely to get from lots of short trips. The range shown seems to assume 60MPG UK which is only achievable on longer trips.

    In regard to abrp as shown above - let’s say you have a 2018 leaf and I guess at this stage that the battery should be at about 90% health. Should I essentially adjust the battery % above to be about 90% also?

    (I guess it’s referring to what % battery you have the car charged to when you leave, but if it’s a few years old and degraded, it would be wiser to set at 90%)


    Hope I’m making sense ! 🤓😬



  • Registered Users, Registered Users 2 Posts: 16,517 ✭✭✭✭Flinty997


    Exactly. Work out degradation and set it to that. You can get a ODB dongle (there's handful that are compatible) that connects to ABRP and will feed it live battery info.

    Theres also speed settings which will show you the effect of speed on your journey.



  • Registered Users, Registered Users 2 Posts: 6,476 ✭✭✭obi604


    Thanks, so I could set a 2018 leaf at 90%. And a 2018 Ioniq 28 at most likely 100%



  • Registered Users, Registered Users 2 Posts: 16,517 ✭✭✭✭Flinty997


    Exactly. It's a really useful tool to test journeys in lots of different cars. Or try different driving speeds or charge durations on a planned journey. Interface is a clunky.

    Also handy to catch out people posting fud about poor range.

    People say it's overly pessimistic but that's probably a good idea. I've not really used it on a journey other than to test it.



  • Registered Users, Registered Users 2 Posts: 6,476 ✭✭✭obi604


    yeah, in fairness, it’s a brilliant resource to have. Pessimism is good here 🤓

    I can't believe you pay Tesla €10 a month for Spotify, Netflix, Disney and live traffic information.



  • Registered Users, Registered Users 2 Posts: 9,830 ✭✭✭CMOTDibbler


    I wonder what else they can turn into a subscription service. Tyre pressure monitoring? Rain sensing wipers? Automatic headlights?

    Madness 🤣



  • Registered Users, Registered Users 2 Posts: 1,394 ✭✭✭MightyMunster


    There is a battery degradation setting in ABRP, it's in Settings, Vehicle Settings

    to use an existing Spotify account in a Tesla you need to pay for Tesla connect?



  • Registered Users, Registered Users 2 Posts: 6,476 ✭✭✭obi604


    is this in a paid version of it?

    Edit: ignore. Thanks for pointing that out.

    This could be an interesting option in the future if it works out. Great for shared/non-designated parking areas. Maybe a few people could share one either. Can't see any specs on the speed other than 30miles added in an hour, so not that fast yet.

    I see there's a bit of huha in the UK re the luxury car tax with EVS included. The threshold is 40k cost price which in fairness is low enough and will capture a lot of new EVs. I think the tax adds about 2.5k over 6 years of ownership. Combined with no grants/incentives etc. It doesn't look like the Labour Govt is helping EVs introduction unless they change this.

    The UK still has the salary sacrifice scheme, you can purchase an EV using salary sacrifice to offset income tax. That's a pretty sizeable incentive for most people. They also still have the ZEV mandate which requires a given manufacturer to reach a percentage sales target per year, the penalty for vehicles under the target is £15k per vehicle. This is under review by the current UK government but is still currently in place.

    It looks like the policy goal is to bring the cost of ZEVs down so that more people can afford them. Looking at the ev-database.co.uk there are lots of options under the £40,000 mark. I find it a bit rich when people in quite nice cars are complaining that they're now having to pay taxes on the cost of a nice car.

    So I've been looking at LFP cells for solar batteries and EVE now have cells which are rated to 70% capacity for 10,000 cycles

    That's 27 years of use assuming 1 cycle per day

    It makes you wonder about battery warranties being limited to 8 years, by all measures it seems the cars should achieve several times that without many issues

    I get that the test conditions are quite different, for example most LFP cells are rated for 0.5C charge or discharge. So an 80kWh battery would be limited to 40kW of power and most EVs would be 2-3 times the battery capacity in terms of charging and discharge power

    At the same time, you'd think manufacturers could be a bit more confident in their products. I suppose from their viewpoint, 8 years is the expected lifetime of a car without any serious issues and anything beyond that is bonus time

    It also makes me wonder what the point of NCM cells is these days. I know they've better performance, but LFP really is good enough for most cases and is much safer and more robust (and cheaper)

    It's good to see manufacturers switching over to LFP, I think that trend is going to increase dramatically in the next couple of years

    In fairness I didn't research the UK prices for EVs but the article mentioned Kona EVs as being captured on the tax which I thought wouldn't be considered a premium EV. Also I'm coming from a retired position so salary sacrifice wouldn't benefit retirees which might be a significant cohort of EV buyers? In any event , if as you say it will drive down EV prices then that's a good thing. On a separate note here in Ireland with all the low cost new EVs coming on stream I'm hoping that this will spur EV sales for 2025 and drive EV growth onwards and upwards.



  • Registered Users, Registered Users 2, Paid Member Posts: 13,547 ✭✭✭✭the_amazing_raisin


    I'd be wary of expecting any sales bump, if you look at the ICE sales then the biggest sellers are typically expensive crossovers, not budget hatchbacks

    There's a very definite trend towards larger vehicles in terms of car sales and I don't see this changing for EVs

    It's great to have the option of budget hatchbacks, but I think the better focus would be to make to price match the EV equivalents against ICE

    This is happening already for some manufacturers, but I think they really shot themselves in the foot with the price hikes from around 2021-23. They seem to have burned a lot of customers in terms of resale value who in turn are spreading bad press about losing a ton of money on their shiny new EV

  • Registered Users, Registered Users 2 Posts: 16,517 ✭✭✭✭Flinty997


    Exactly this. Its in their interest to move the market to more expensive vehicles like SUVs because there is more profit margins in them than smaller cars. Is true of ICE and also for EVs.

    True they've burnt their market with a price war. But that started with Tesla, trying to maintain market share long before the Chinese became a factor. Tesla don't sell used cars. Nature of a new market though, hard to avoid.

    See easy go have a night rate trial on some public chargers.

    I would also be worried medium to long term that cheap used EVs may encourage people to ditch the bus or train or bike or scooter to use a car with low fuel costs. Think of service jobs, cleaners etc who get the bus to work instead commuting long distances for nearly bus like costs. You also have those who want a brand new reg number say 151 even if it's the cheapest if the cheap car. Good for the used market but may end up with more traffic on the roads.



  • Registered Users, Registered Users 2 Posts: 16,517 ✭✭✭✭Flinty997


    They won't because EVs get stuck in traffic the same as everyone else.

    Once the Public transport, or bike become a lot faster or easier people will eventually switch. You just have to make driving so much harder. Some people will still drive even where walking is quicker.

    I'd be similarly worried, particularly since our new overlords have adopted a kick the can down the road attitude towards public transport and cycling infrastructure

    I used to commute into Dublin from the suburbs and the fastest route is to cycle. There's no continous cycle path and in many places I'm sharing a busy main road with grumpy car drivers

    There's a plan to open a dedicated cycleway all the way to the city, it'll be interesting to see if that gets shelved
