I recently bought an EV with a 220-ish mile range, but that's really a 160ish mile range given fast charge craps out at 80%.

I drove it ~900 miles and I had to recharge seven times. This added 3.5 to 4 hours to the trip. I'd say the first 2 of those were good for my mental health but the remaining 90 minutes were spent at broken charging stations with low charging rates or just broken.

Love the car, hate the current charging infrastructure. And the anxiety induced when power drops below 20% and you're approaching the next charger sucks, doubly so when you get there and it's broken and now you have to find another fast charger before you run out of juice.

There's fancy route planning software (ABRP for example) that will try to minimize charging times and total travel time but it seems to make the assumption that you will always hit a perfectly functional fast charger and it doesn't seem to take weather into account.

I was averaging 3 to 3.5 miles per kWh until I approached the Bay area in 100+ degree weather and it dropped to 2 miles per kWh.

Fortunately having been burned many times already (every single Fred Meyer seemed to have a broken charger for example but the navigation software kept directing me to them), I had instituted a hard rule to always charge to 80%. So I made it to Richmond and the next charger before I ran out of power. America's clean electrical future remains a work in progress.

So what you really seem to need is about ~400 miles of range which translates to ~300 miles of range at an 80% charge or so. I think we're getting there.
