Phoenix weather has always been hard on car batteries. That statement could be ammended to say "EV battery packs could operate reliably for 15 to 20 years except where it really hot like Phoenix, Arizona".
Well that depends on if there is an active battery thermal management system, like the one on the volt which can heat or cool the battery pack... Active thermal management will definitely extend the life if you live in either extreme heat or cold climates.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
