New battery chemistry tweak could double EV range

Re:New battery chemistry tweak could double EV range by White_Wolf on Tuesday August 10, 2021 @12:39PM (#28130978)

I'm looking at like this:

Max speed limit (in UK) is 70mph.

300 miles battery is 4h

4h is the maximum reccomended to drive without a break. I'd say 300 miles is just about right in terms of distance to force those like me to take a 30 min break.

Edit: I'd go for cheaper at this stage. Also as low tech as possible.

Do you own a BEV though?

At 70mph, your 300 mile range car is getting maybe 250-270, if it's 21C out. if it is colder or hotter, range does drop a bit to a lot. Dead of winter can get more like 150-175 miles range.

Then on top of it, for road trips, you often use the battery from 10-60.

Combine those two things, and your dead of winter BEV is needing to stop like every 100 miles.

But, thats like 5% of trips. most of the time this is vast overkill.
