Do Electric cars have a £/charge calculator

[Glade]

My Dad is a tight northerner. Never has the heating on, always switching off lights etc.

Do EV cars generally have a calculator that allows you to input a £/kwh rate, and then a calculator to tell you how much your last charge cost?

Because if i start running an extension lead accross his drive to my car when I visit, he'll be wanting me to pay his electricity bill!!

tell him you captured some regen power and your battery is overcharged and you need to off load, so will give him some electricity so you can charge him..... ;-)

No need the maths is basic:


Know what you are paying for electricity. Lets say 10 pence per kWh

Know how big your car battery is. Lets say 40 kWh

Know how discharged your battery was. Lets say 50 %


50% of 40 Kwh is 20 kWh. 20 kWh @ 10 p/kWh is £2.00




Or, assuming you are charging with a granny cable when at his house, ie from a 3 pin plug, these are rated at 13 amps max, which is a power output of 3kW, or 3 kWh for every hour you charge, which at our 10 pence per kWh, means 30 pence an hour for every hour you charge.

Max Torque is right - but one thing I'd like to just add is the 13A 'granny' cables will typically limit the current to 10 amps, just to reduce the risk of anything overheating, so the maths adjust slightly.

But on the flipside, it's basically so cheap that you might as well bring round a nice bottle of wine, or take him out for dinner somewhere as a thankyou and leave him in credit (and your battery ful!)

But bear in mind that charging rate drops when you get near full - tho less of a problem with granny charger

My rolec charger tells you last charge cost, monthly cost, total cost etc

As does my Podpoint, but the OP want's to bum a few coulombs from his Dad via the 'granny' charger.

Even if it’s only a small amount, I’d feel bad going anywhere and not offering to pay for what I had taken. I guess a simple calculation and a little extra is fairly easy.

Seems like a simple feature to implement though. But seems like it’s not usually in the vehicles?
