Today, the depreciation of capacity of a Lithium ion battery for automobile is quite significant. An improvement of the life time will definitely help the proliferation of an e-car or hybrid car in the world. The application area can be expanded to electric charge storage for solar like Gupta said. In addition to lasting and charging, size might be one of the factors that consumers would like to see improvement.
If the battery is really longer lasting and easier to charge, it can revolve the whole E-car market immediately. Right now, I don't think E-car can easily get into mass market in China (at least in China) as the long time wasted in charging is not solved and there is not good enough incentive for people to switch. The Government funding is just a political act while the Chinese will soon has new leadership next year, will they keep on emphasizing this 10-cities-1000-cars agenda?
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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
