Create a low-cost electric vehicle charging station with Arduino

Creation A low cost VE loading station with Arduino

Arduino Team — April the 23, 2024

THE high cost of VE (electric vehicle) chargers can lead You has believe that they are complex systems. But with THE exception of You're here Compressor, that is not it TRUE. They are In fact enough simple — basically just glorified switches. All of THE small detail gravelly loading details are THE responsibility of THE cars on board circuits. With that In spirit, VE the owners can to want has follow Rock Nevès guide on building A affordable Based on Arduino loading station.

Because THE car offers with all of THE details of loading, THE only aim of THE "charger" East has provide A connection has THE electric grid. "Charger" is not it even THE RIGHT word, as This East more precisely EVSE (electric vehicle provide equipment). For security the reasons, THE car And THE EVSE communicate with each other. THE car can say THE EVSE When he East on has provide power And THE EVSE will SO connect A to change between THE loading socket And THE electric grid. He Really is not it any of them more complex that A $15 clever exit And most of THE cost of A EVSE East THE large caliber wiring.

Here, Nevis prove that with A DIY EVSE designed around A Arduino UN Rev3 advice. He has A custom shield with relay For switching power And has power THE Arduino himself with sector tension. A little LED act as Status indicators. EVSE protocols are standardized, SO Nevis was able has program THE Arduino has communicate with any of them connected car. Once THE Arduino receives authorisation Since THE car, he switches THE relay has provide sector tension. A foolproof 3D printed pregnant contains those Components, with A breaker to change And protection against bad weather.
