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.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
