Thank you for posting.
EV technology needs to be pioneered and "domesticated" imo.
In the meanwhile...
A percentage of power gets lost due to internal battery resistance, including when charging.
And speaking of charging, not only are EV lithium batteries known to not hold their charge when weather gets cold, but it surprised me that batteries are claimed to take longer to charge when they are cold.

Corrections, insights welcome.
From your link: “Funding was provided by the U.S. Department of Energy (DOE) Vehicle Technologies Office (VTO).”
Jennifer Granholm, the perky and corrupt former governor of MI runs a DOE full of EV evangelicals and insider traders in EV and related green energy stocks.
Just my perception of course.
