Detoriation at 100% starts immediately sonif you need 100% do it in JIT style.
I am unsure if it being colder when stored at 100% makes any more difference.

A lot of assumptions there. Cold weather does mean that it can take longer to charge and that range drops. However it doesn't damage the battery. It would if the battery was not designed to mitigate the damage however, Lithium plating can happen when temperatures are low. The majority of EVs have battery management which heats the battery so that plating doesn't happen.

Additionally, if you live somewhere cold, you can usually pay for a heat pump as an add on which improves both your range and your charging.

Doesn't the battery heat itself as it charges? My cordless drill ones heat up whilst being charged.
I would think fast charging would be more damaging tbh. Are they charged faster than say a 5ah 18v battery in 1hr?

As I understand it the battery packs are " over provisioned ", so for example a 100kWh stated battery pack will in fact have 110kWh of cells to protect the pack from over charging/ discharging.

Yep. There is loads of tech built into EV batteries to ensure that they last. You can't just buy a new battery on Amazon, so battery management software and tech is essential.

Thinking of charging the i4 to 90% now its colder to keep range up, any issues? I'll add its a company car.
An addendum - the ID4 has been programmed to constantly badger the owner to use "battery management mode" which limits charging to 80% unless you override it on the screen or app and tell it to charge more. TBH if I'd bought the car I'd probably use it, but as I hand it back in 3 years and get something else, it's not top of my concerns unless the lease company tell me different.

A long while back I viewed a table of voltages in relation to longevity. High capacity cells had the shorter life and higher voltage. Yes they can ge that 10kw higher with lower duration. Whether you can really describe it as over provisioned I am unsure. One of the smartphone manufacturers gives you 1600 charge cycles in a similar way , alongside a risk management style of charging.

Ignoring EV battery care advice is no better than being late with ICE car oil changes.

Unless the battery packs are pre heated for charging it would be best to stick to 3KW charging if you can, especially in winter.

The Nissan Leaf doesn't have battery heat/cooling with coolant. The max charge rate is 50kWatts, so home charging at 7kW is fine, its small rate of charge.

For hybrids with a 2-8kW battery, then for cost saving on not having a dedicated 7kW outlet, 3kW is plenty, charging up in just a few hours.

They all compete on range.
I doubt much over provisioning takes place, at all. Though Tesla once provided a lower range car that was supplied with the longer range battery. And which could be released at a later date for a fee.

As I said. It's a company car. If it was ICE, they would be scheduling servicing or oil changes. There has been no guidance on whether or not to use the built in battery care system.

"That said, for one owner, the maximum range was down by 2.2 percent after having driven over 20,000 miles.
Model 3 LFP, bought in January 2023. 21,504 miles, full charge shows a 266-mile range over the original 272-mile range, 2.2 percent degradation. I live in an apartment, so I charge to 100 percent whenever possible, and don't stress about it. "
Bear in mind that this site tends to be OTT in marketing hype.

And also, cynical me says the dashboard will surely show what the manufacturer will choose to display. Post warranty is where a bit more truth will happen.

The problem is that that "range" calculation is based on how you have been driving the car as range is all relative. My range is very different if I do a load of motorway driving to what the prediction is when I am mostly "city" driving.
