What’s the maximum charge rate you have seen??

[OB1CCFC]

So I’ve had my 1st Edition for about 15 months, 12,300 miles, probably a dozen ionity charges on a warm battery starting at 25 to 35%.
I’ve never got over 58kwh.

On 50kw chargers I don’t think I’ve ever got over 45kwh.

How about you guys??

87kW at a 100kW charger at a Moto services near Donnington. Overall it took 49 minutes to add 47kWh to the battery.

69kWh @Ionity Leeds (350kW) SOC at start 31%

Not sure I understand that graph. Does it imply 0 charging rate at 35% SOC?

Edit - I stopped charging at 34% (splash and dash)

I got 65kw when I tried one of the new 75kw osprey chargers a couple of weeks ago. Suspect I'll need warmer weather to best that by much. Am just on a Gridserve for the first time - maxing out at 43kW (to be fair, I don't need any more, the limiting factor is my son's eating speed...)

I've had over 100 on an ionity charger on a summer day with a warm battery under 20%. It was glorious, but sadly very much the exception that's for sure. There are so many variables it's staggering. I rather like 50kw chargers, mainly as you tend to get something around 50 out of them!

A summer day implies you've had the car a while, so I presume it's a Tour if you were getting over 100?

highest was 89 on an Ionity, at 20%, but for a short while.

I also tend to use 50kw chargers because they are more consistent up to 80% than the Ionity (in our experience). Plus, the 50s are all free where I drive.

I have heard that you only get very high charge rates when the battery is over 25°C, which makes me wonder why it doesn't use some of the KW to run the battery heater and get it up to 25° instead of sitting there drawing 37KW from a 120KW charger. :-/

It's worth noting this has it's downsides, especially of it acts in a fixed way regardless of maximum charger capability. Only last week Tesla Bjorn released a video showing a Model 3 that only charged at 7kW on a 16kW charger because the other 9kW was being used to continuously heat the battery pack! Sure 16kW DC doesn't really exist here but at some of the slower gridserve chargers it would be a significant chunk in terms of both charge rate and cost if the ID3 was running it's 8kW battery heater on max while charging.
Would be nice to have the option of preheating on the way there though.

^^ This. Tesla and now Polestar do this - if you have a rapid charger as a destination in the nav - the car will warm your battery for arrival. This is hinted at coming to the Id series with SW 3.0. Along with many other things (ie don’t believe it until you see it!)

My suggestion doesn't require any integration with the nav, it simply involves running the battery heater at the start of the charge to get it up to 25°.

The act of fast charging will warm up the battery in ten min or so - but preheating the battery means you get the full rate from the start.

Heating the battery takes ten min to raise the temp by ten degrees in the morning - so sitting at the charger for ten min before charging to save ten min of charging time kind of defeats the object

Just sounds like ways in which we can be charged for even more KWh to me...

I guess it’s choice isn’t it. There are times where I wouldn’t mind sitting by a rapid for 45 min chugging away at 40-50kw - but also times when it’s late and I want to get home and I’d rather spend an extra £2 and only wait for 25-30 min! (Usually when there’s a grumpy small child on board!).

"You can please some of the people etc etc..."

I was out on Sunday (in my son's Clio giving him driving practice, but it was a nice day) on our trip along the A55 there are a number of ex Little Chef's some are Burger King's, Starbucks etc now.. I suddenly had the thought that had the timing been different, the Little Chef model might still be successful now if it had a car park full of chargers. We've built ourselves this instant order fulfilment world that brings a lot of disposables with it and now we have to wait for our cars to charge.

Fast food isn't that fast these days - when my kids get their weekly McDonald's, I usually oder on the app and wait in one of the collection bays rather than run the gauntlet of drive through, and even then its a 12-20 minute wait. You now also have lots of impatient delivered and uber eats drivers (usually East European) honking their horns constantly, parking illegally to block people in and flying from behind drivers trying to reverse out of a space and leave - its like driving around the Arc de triomphe. I hate being asked for a McDonald's to bring home!
