81% of original capacity for many cars means when driving at highway speeds you will get like 250 miles or less range per charge. Still dramatically less than gas cars.
My EV gets only 230mi range at max, and I only charge to 85% which is like 190mi. But I do it at home and never have any range anxiety.
The trajectories for battery improvements indicate it is just a matter of time before those with larger range needs are addressed satisfactorily.
If you cannot slow charge at home or work, it’s a tough story, EV’s aren’t right for you yet, and that’s ok. Roll out of slow charging is less clear that it will be solved in a scaled way. I am not one that believes that 5-10m EV charging is a good goal, it’s very high power and likely not a good price trade off for the time saved. Current 20-30m will likely be the broad solution for those that want EV and cannot charge at home, though I think that’s not a very good solution.
My old '07 Focus would get about 260 or so miles between visits to the gas station.
If you have to drive 250 miles every day for work, or you don't have kids and can do 3 hour legs on trips without stopping, then get a gas car.
