As others have mentioned it's as well as not instead of.
However it's boneheaded to charge to 100% the vast majority of the time as it's often as slow to charge from 20 to 80% as it it from 80 to 100% on an ultra rapid charger as it massively slows down above 80.
I can charge twice from 10 to 80% with my car in about 40 minutes for a range of almost 500 miles vs. One 10 to 100% for a range of almost 320 miles in the same time.
I only fully charge at home and only if it makes sense for the journey I'm doing. It's not good for the long term health of the battery to repeatedly charge it to 100% all the time. Plus it's kind of a dick move to block fast and ultra chargers with the slow charge above 80%.
Then there's the cost, I don't want to spend 45 to 75p a kWh to charge on a public charger when I pay 9p at home on my ev tariff. If I do need to charge I only charge what I need, which can be as little as 5 minutes for about 60 miles.
Sure, not every car comes with 350kw support (or even 250kw) yet, but more will as people realise that charging speed is at least as important as range if you plan to travel in Europe.
What car has almost 500 miles of range at 80% state of charge?!
While new models get released all the time, the Lucid Air is known to have one of the longest EV ranges and it is around 510 miles from 100%.
A car would have a total range of around 625 miles at 100% if it is getting 500 miles at 80%.
Charge to 80% twice, if you read what I wrote, is almost 500 miles, and takes about as long to charge both of those times in total vs. charging just once to 100% on an ultra rapid charger.
