How to charge an EV using Solar, OCPP, and EVCC

Published at : 23 Dec 2025

My problem started when I bought this car. As an electronics engineer, I didn’t want to leave this planet without owning an electric vehicle. With its 650 horsepower, it’s a thrill to drive — and with 3.8 seconds from 0 to 100 km/h, or 60 mph, it reminds me of my sporty motorcycle. The car is a Smart #5, BTW. I used OCPP 1.6J and EVCC to solve the problem
