Building a DIY Open-Source EV Charger with Arduino

Who needs expensive commercial EV chargers when you have Arduino, open-source software, and a willingness to learn? This talk chronicles my journey building a fully functional EV charger from scratch, covering everything from safety considerations and electrical engineering basics to the software stack that manages charging protocols.

We’ll explore the open-source libraries that made it possible, the challenges of implementing J1772 standards, and the satisfaction of plugging your car into something you built yourself.

Perfect for makers, engineers, or anyone curious about the intersection of hardware hacking and sustainable technology.
