Yes, it underperforms now.
Btw, “cycles” isn’t days. Most people do not drive 300 miles a day. If you do you shouldn’t be driving EV anyway. A hybrid or just a fuel efficient high compression diesel would be better.
My own suspicion is that they may have been recharging the battery like they do a mature tech lithium batteries and that battery memory is a significant issue at this time if you don’t do something extra. It may sound like I’m insulting but really it isn’t uncommon for people to just overlook obvious things while they hunt down percentages.
I think of a cycle as “drain and charge.” So, if you drive 50 miles a day and charge overnight, I see that as a “Cycle.”
Frankly, I think the future is in something more like a graphene capacitor.
