My understanding is that this is largely a myth, at least with modern BEVs with intercooled battery packs. My understanding is that modern battery packs can Level 2 charge with no additional degradation, because they don't get any hotter than during a Level 1 charge.
Level 3 charging is different, but even then, the degradation in battery life isn't as much as you think -- I've heard numbers as low as just 3% faster degradation.
That makes sense, my experience is with a first gen VW e-golf which just has plain batteries- no cooling.
I actually do that with my phone- I use a fast charger with a peltier cooler, that can rapidly charge the phone while keeping it cold. Family/friends think I'm crazy for caring about it, lol
