Arizona State University Professor’s Work to Stabilize the Grid Pays Off

Cars That Think

Whenever new technologies are introduced into the power grid, there’s always a chance they could disrupt the system, possibly even leading to blackouts. Finding ways to deal with the impact on the grid caused by incorporating renewable energy has been the focus of Vijay Vittal ’s research for nearly 20 years.

Then, as now, wind farms are operating off the world’s coasts—but not all of these offshore sites are connected to the mainland via underwater power cables. Airplanes, for example, won’t be able to fly long distances on battery power. Many countries have met their climate goals and are on track to be completely carbon neutral.

Practical Power Beaming Gets Real

Cars That Think

While a wireless charger saves you from having to connect and disconnect cables repeatedly, the distance over which energy can be delivered this way is quite short. Indeed, it’s hard to recharge or power a device when the air gap is just a few centimeters, much less a few meters. This wouldn’t be such a silly connection to make.

Q&A with CharIN North America President: It’s all about interoperability

Charged EVs

The High Power Charging system is 500 kW, and the Megawatt Charging System is going to be multi-megawatt [up to 4.5 Charged : We recently spoke with a company called Rocsys [see our feature article in this issue], that has developed a robotic automated charging system. megawatts]. Any thoughts on automated charging? It’s a must.
