Electric car and in laws.

I've never heard of a 'granny charger'!
In fact i didn't even know we should be re-charging her. Could that be why she sleeps so much?

I'm also not sure I want to rummage around Granny to find the socket....😳

You can charge safely with a 3 pin plug. But it's slower.

Yes, would much prefer an electric cat over an electric car

I’d stop them on the fire risk. They shouldn’t just be charged in a normal socket. But yes it’s cheeky.

If you owned a petrol station it wouldn’t mean they could just fill up for free so why expect it just because you own plug sockets.

I have an EV and always ask guests if they want charge their car while they're staying. It's not always easy or convenient to charge your car away from home. Do you know where they could charge it quickly near you?
It's not expensive but it's a little cheeky to do it without asking.
Charging via an extension cable is pretty risky though. I wouldn't do that.

I have an electric car, as does DH. They're brilliant and I love them but I would never do this. For one, it's cheeky. For two, normal plug sockets aren't designed to cope with charging such a huge battery. It's dangerous. DH melted a socket in our garage doing this before we got a proper home charger.

It’s more like 3 miles per kWh not 3 kWh per mile, so about 8p per mile.

Depends on where you live really. The ev charging network is rubbish in the countryside in the uk, they could be driving 20 miles to the nearest quick charger. Ask them to install a charging cable on your house to cut the risk of fire. We have a plug that we charge the car on that came from Halfords, its specifically for ev charging. Takes about 4 hours on cheap.electric overnight to put 40% in the battery. That'll do about 50 miles without heating on! In laws should contribute something though.

I have a holiday let with an electric car charger (plugging into a standard 3 pin socket is a fire risk). My guests seem to just charge once in a week and it usually costs about £15 (according to my smart meter). So via a granny charger I imagine it will be less. I imagine your PIL have got used to topping their car up each night, but I do think it’s a bit cheeky and definitely not thoughtful.

Ask for a contribution?

Is your dp upset as well? Maybe they okayed it with him before the trip. This is obviously what they do at home so probably didn't think anything of it and wouldn't think it would upset you to this degree.

Of course you're not being cheap. Just talk to them! Say you're struggling to pay your bills and so it would be appreciated if they could please cover the cost of the power usage as it's unaffordable for you.

I'd love an electric cat😹

Showers comment is unnecessary and nasty.

they are cheeky fuckers, I’d unplug and say “we can’t afford this” and when they do goldfish face direct them to their son for explanation.

when you say they are running an extension lead, are they leaving a window open for this?
I’d be fucked off with that.

It wouldn’t bother me. Our car costs around €8 to charge from 0. That’s for 550km. So I doubt that have used more than £10 for the week even if your unit costs are higher and they still need to be driving a lot per day to make a dent. Just topping up each day isn’t going to make it higher than running flat and charging all at once

What EV is using 3kWh per mile? It’s more like 3 miles per kWh so call it 10p per mile.

Shouldnt be charged at home without a proper charger as fire risk. Find out the nearest local charger and ask them to charge there due to fire risk.

Depends on the car but some charge for like £6. I wouldn’t be happy with the extension lead set up though.

My concern would be safety, not cost. Using an extension raises the risk of overheating, and when everyone is asleep? No way.

Say 3kwh per mile, 25p per kWh - 75p a mile

Are they taking you anywhere or just driving large distances themselves?

Do you also charge for showers ?

I have an electric cat and would never dream of doing this.
My car £70 per month to charge, I used to spend £400 on petrol.

It's probably a lot less than you think, how many miles are they doing a day

What does your smart meter say

Granny chargers charge at a rate of around 2.3 Kw/hr.

So take your rate x 2.3 = how much it is costing per hour plugged in.

I don’t use a granny charger as not comfortable with them in a standard 3 pin socket as they can overheat the socket. Do not leave unattended.

I think it's cheeky.
I'd ask how much does it cost to charge each night. And make comment, You know we are really struggling with COL etc.
Surely they should offer some money towards the cost

It costs hardly anything to charge an electric car. I’m surprised they need to charge each night unless they’re traveling great distances though! Surely the car has a range of at least 200 miles? They’re family, I wouldn’t really count it as much different than charging a phone to be honest.
