Hi Lee etc,

I also have about 80% left on my 2013 Leaf with 56K miles and it has the
option of only charging to 80% - which I do locally unless taking a longer
trip. (didn't you mean Leaf not Prius?)

Same with the Chevy Bolt (2020) but GM hasn't figured out the 20-80% local
trip thing, replaced batteries in the past of ignorant users.

My Tesla Y (2021) beats you over the head if your stupid and charge above
80% (just before leaving on a long trip I charge to 100%, 140K miles so far,
265 miles range - was 320 new)


Have a renewable energy day,

Mark

My long-time strategy is to keep the SOC between 20% and 80%. Don't drive to
go below 20%, and don't charge above 80% unless I expect to take a
longer-than-usual trip.

I've always used my EVs for daily commuting, which had a predictable range
requirement. I didn't charge every day as long as the SOC was high enough to
make the next day's commute without going below 20%. That meant I only
charged once or twice a week.

This strategy was good enough to get 5-7 years life on my old lead-acid
packs; even more on today's lithium packs. Our 2013 Prius with 65k miles
still has about 80% of its original range.
