Engineering students at Hope College in Michigan designed a new EV charging system to be used by students on campus, but when not in use actually charging EVs the solar-powered devices send power back to other buildings on campus. 

It's a brilliant way to help the university keep energy costs low, maximize sustainable energy over higher carbon emitting sources, and can provide a great source of back-up power if needed to add resilience to their entire system. 

Bravo to these engineering students. I hope they got an “A” for their project.
