My Corsa-e says it’ll do 222 miles WLTP, up from 209 miles with latest update.

With a rapid charger it says it’ll charge from 15-80% in 30 mins.

My question is, When using a public electric charger, will it only charge to 80%? If so, that’s not getting me my “222 miles”.

Am I ever going to be able to charge to 100% using public chargers? I can’t get a charger installed at home.

If it’s 15-80% in 30 mins, I’m assuming it’ll take a bit long than 30mins if I’m charging from 1%.

Hopefully y’all get what I’m on about.

Thanks

It might be worth joining a car specific forum or Speak EV.

Two things about charging over 80% for most EV’s, the battery doesn’t like it and the charge curve tapers off after 80%. That is to say, it becomes so painfully slow to charge over 80% you would be better off on a long journey driving for 150 miles (or whatever) and then charge again. That way you will always be charging at the fastest part of the charge curve which keeps the journey time down.

I haven’t heard anything about charging restrictions aside from car park restriction rules. You should be able to get to 100%

The more electrons you need the longer it will take. So charging from 1% will take longer.

And I hate to be the grinch, but best of luck getting 222 WLTP miles, especially in winter. But I guess you already know that.

Well done on getting an EV.

I don’t have an EV but my understanding is that when you hit 80% charge it slows down to protect the battery. It will charge to 100% if you want but 80-100 will be at a slower rate.

I think the 80% charge is another thing they recommend to protect the battery. I think they say you should only charge to 100% if you’re going on a long journey where you’re going to use the battery in one go.

I have often thought that you need to do some maths when looking at the max range of the car because like you say, you’re not getting the max range charging to 80%.
I’ve never really noticed anyone talking about this when I’ve read about EV’s so I’m not sure if we’re missing something.

I assume you’ll also need to factor in how much charge you have left before you charge again so if you charge at 15% that’s 15% of your range you haven’t used.

222 – 44 (20%) = 178 miles. Then run that down to around 33 miles (15%) and you have a usable range of around 145 miles before you charge up again.

Hopefully someone can add more to this as my EV knowledge isn’t the best and I could be talking absolute rubbish here!

Apologies @DumfriesDik I was writing my reply while you posted

No drama @DNtruth – at least we said the same things!!

X – Some really good answers have been provided to your questions from those who know far more about EV’s than me, but in reference to DumfriesDik’s very good point about quoted range versus real world range, there was an interesting thread on this recently. Even with 100% charge, EV drivers were reporting that actual range can be quite a bit less than quoted range especially in the winter months, so you will need to allow for that, on top of any shortfall that only charging to 80% will result in.

Thanks guys! Really helped me understand. Excellent forum! Much appreciated.

I charge my Kona once a week overnight at a local park and ride. Only on a rapid charger will the charge slow down. I charge on a 22kwh charger and it charges at 7.5kw until 98% then drops 2kw. Takes approximately 8 hours. I keep an eye on the app to see how the charge is going.
