DHL Orders 12 Eviation Electric Cargo Planes - AVweb

More green washing. Has anyone sent any of these folks a list of specific questions regarding any of these issues and how they intend to address them?
One question, I have not seen anything on is we know that batteries lose efficiency as the temperature drops. We have all probably seen the EV stories where range is cut in half or a fourth during cold weather. Last time I looked at the air temp while flying, it got colder the higher I went. And it tends to get pretty cold at flight levels used by commercial aircraft. What will the effects of cold temps at altitude be on battery performance?
