Portable EV Charging Portal
Abstract
These days, EVs are everywhere — but charging them without a grid nearby? Still a huge headache. During one of our field trials, we kept facing issues with reliability and power access, which pushed us to try building something different. What came out of that was a compact, foldable solarpowered EV charging setup with lithium battery storage and a custom power conditioning system. The idea is simple: give people the ability to charge EVs on the go — even in remote or emergency areas — using just solar energy. It's got dual input (solar and grid), modular batteries that can be swapped in seconds, and even the potential to link up with blockchain energy credit systems so people can trade or save unused energy. Also, we figured out how to store excess charge during hot sunny days and use that during winters — which is actually super helpful in seasonal climates. The system isn’t perfect, but it works better than we expected in most test scenarios.
