Controlling 3.6kW of photo voltaic EV charging with an Arduino GIGA R1 WiFi
Arduino Group — March 4th, 2024
The EV (electrical automobile) versus ICE (inside combustion engine) debate is extra difficult that it might appear, however one reality is sort of easy: it’s a lot simpler to generate electrical energy at house than it’s to refine fossil fuels. Because of this it’s attainable energy a automobile without spending a dime after the preliminary funding. However doing so takes numerous {hardware}, which is why Shawn Murphy developed this charging system managed by an Arduino GIGA R1 WiFi.
Murphy owns a Ford Lightning electrical pickup truck, which is inefficient by EV requirements because of its weight. However even at simply two miles per kWh of electrical energy, he estimates that he can break even on the price of his photo voltaic charging system inside 4 to 5 years. After that, the electrical energy to energy the Ford will, primarily, be free. Any extra vitality can energy his house or feed again into the grid.
Simply powering the truck alone would require lots of electrical energy, so Murphy acquired 10 used 360-watt photo voltaic panels. These feed to a battery backup array, which provides energy to the Ford charging station.
To maximise effectivity, Murphy desires the photo voltaic panels to pivot on one axis to comply with the solar. He estimates that can enhance their output by 20-25% all through the day, which is a big quantity of vitality with a photo voltaic panel array this massive. An Arduino GIGA R1 WiFi board controls the lean of the panels through linear actuators. Murphy initially used “dumb” actuators, however is switching to “sensible” fashions from Progressive Automations that embody positional suggestions via Corridor impact sensors.
A GIGA Show Defend offers Murphy entry to an interface, which he can even entry via the Arduino Cloud. Along with controlling the linear actuators, the Arduino screens energy era and consumption.
That is nonetheless a piece in progress as Murphy continues to make enhancements, however he’s nicely on his option to “free” vitality for his truck.
