Home charge points (purchase/problems/questions) (See mod note post#1)

You would be in a very small group of EV owners if you managed to go every two weeks between charges. What size battery are you looking at? A portable 13A charger (AKA granny charger with a 3 pin plug) will provide approx. 1.5kW per hour, so a 60kWh battery would take 36 hours to charge from 10% to 100% for example.

If so, there's plenty of time to install one if and when the necessity arises. Especially as such necessities usually come well forewarned. Why spend upwards of a grand on something you might never need? A granny charger will give you 20kWh in the nightsaver window and if you need to add more, it's still going to be cheaper than the cheapest public units.

If you're only needing a charge a fortnight, then the thing is always going to be nearly full or at manufacturer's recommended maximum. With that kind of usage, you'd only be using the granny charger once every few days. What difference is a 7.2kW charger going to make with that kind of usage? Charged up in an hour instead of three?

And the sense is in the cost. An outside socket for €35 vs €1000+

Well I did it myself, so that's why it only cost that. Needed it for a power washer, so it's handy for the granny charger if I ever need to use it.

Battery size is 70kwh (I think?) Car has a WLTP of 510km. We normally do about 120km per week approx. So I was thinking I would get away with charging once every two or three weeks and so it might not be worth getting a night rate - why push the day rate higher when I will only use night charging once every 2 or 3 weeks is sort of where I'm coming g from.

There is an Aldi beside me and they have chargers so I could use those and see how I go for a while I guess.

Thanks for all the advice everyone

I’d a tenant that was in the house for 12 years there was a prepay meter in the house when they moved in. ESBN swooped it out for a normal

Meter after a few months. 10 years I got a call from Electric Ireland asking what’s the story , that the meter hadn’t been topped up I. 10 years and they believed the tenant bypassed it. It was only after they went to

eSBN to investigate did ESBN tell them that they replaced it. The tenant had free electricity for 10 years. Explains why they never used the gas boiler and had plug in rads

I'm doing 1000km per month in my EV and I stayed on the Flogas 24hr plan of 23c per unit, the car accounts for 20 to 22% of the electricity used in the house. I'd definitely recommend getting a proper CP fitted especially if it's the only car in the house. Knock at least 120km off the wltp figure and more for winter driving, that's what you'll be getting in the real world.

how many units annually do you use at the moment?

if you forget to change the “charge at preferred times” on the goodbye screen in the car, can it be done from the mobile app?

I'm not sure about that tbh, I don't use the app much as it's very limited in what it can do, I use the Tronity app to keep track of charging (costs etc.). The Cupra app will tell you the car's unlocked but you can't lock it from the app🤔

A 7KW charger isn't going to be that much use in an emergency either, you'll still need a few hours charging.

You'd be kuch quicker just going to a public fast charger, in that unlikely scenario.

Yes you can, when its plugged in. Click on the Battery tile and it will give you a popup to change the "mode".

I agree with @listermint that a proper dedicated charger should be installed. While it won't help much for emergencies if the vehicle charge is low, the person with a dedicated charger is more likely to plug in and keep the car topped up. I know a granny could be left plugged in, but I would be against that, as I don't like the idea of an external plug being left plugged into a non-dedicated external power supply box, such as those used for sprinkler, or pond systems where the cable is routed directly into the power supply and is not using a plug.

I occasionally use a granny charger if both vehicles need to be charged. I tend to keep the cars above 50% and that usually means 2 charges per week per car. I just think if someone has an EV, they really should have a dedicated charger and use the granny only as a backup charger…..maybe when visiting granny.

I'm not an expert, but the the difference I see between a fan heater, or kettle and a granny charger is that only one of those items will be running for several hours at a time. They all share the same fuse rating, but the kettle is active for a few minutes at a time. The fan heater variable but again, often 20 minutes or less. If the person with the 70kWh battery is even charging from 50% to full, it will take approximately 16 hours at full draw to charge up. That's a long time for the item to be running at full draw.

My opinion remains the same. If you have an EV, a dedicated charger is what you should have at home. A granny charger is a back-up when you have no other option. Granny chargers can and do fail, especially after a few months of being exposed to the elements and being thrown about from car to ground. I have a lot more faith in a dedicated charge point, but I do see your POV and accept it works for many people. Unfortunately, it's just not as safe using a granny charger.

Ghost is correct granny chargers are occasional use items. Leaving a high consumption on over night for 10 hours or so is inherently unsafe. I'd value both the convience and safety of a dedicated charger for let's face it tiny money in the scheme of buying a new EV. It's pure scrimping to rely on a granny charger.

Plus we're close to a point that chargers are a good addition to a home sale too.

Convience safety and better charging rates. Win win
