Creating a low-cost EV charging station with Arduino | Arduino Blog
blog.arduino.cc
The high cost of EV (electric vehicle) chargers may lead you to believe that they’re complex systems. But with the exception of Tesla’s Supercharger, that isn’t true. They’re actually quite simple — basically just glorified switches. All of the nitty gritty charging details are the responsibility of the car’s onboard circuitry. With that in mind, […]

    This seems to only be a substitute for low-current single phase chargers.

    Here in the EU, cars charge between 11kW and 22kW off of 3 phase. This isn’t accomplished with an simple smart charger.

    Also this is completely negating fault detection, safety relays, charge current negotiation, etc…

      That seems great for things like apartment chargers, or other rentals that don’t need fast charging, but are hard or expensive to install home style chargers

    I’m generally all for DIY, but high voltage/high current stuff like this seems least appropriate for it.

    Plus, I imagine most of the cost of building a charger is in the beefy relays and such, not the control circuit.
