Electrical automobiles have gotten an increasing number of widespread on the street, however once they’re parked within the driveway or storage there are nonetheless some kinks to work out when getting them charged up. Certain, there are many charging stations in the marketplace, however all of them have totally different options, capabilities, and even ports, so to essentially make it possible for full management is maintained over charging a automotive’s batteries it may be vital to succeed in into the components bin and pull out a trusty Arduino.
This mission involves us from [Sebastian] who wanted this stage of management over charging his Leaf, and who additionally has the abilities to implement it from the massive excessive voltage switching contactors to the software program operating its community connectivity and internet app. This charging station has each accessible function, too. It will possibly inform the automotive to cost at totally different charges, and may limit it to charging at totally different occasions (if power is cheaper at evening, for instance). It is ready to monitor the automotive’s cost state and different data over the communications bus to the car, and even has a front-end internet app for monitoring and controlling the gadget.
The mission relies round an Arduino Nano 33 IoT with the entire code accessible on the mission’s GitHub web page. Whereas we might advise utilizing excessive warning when coping with mains voltage and when interfacing with a high-ticket merchandise like an EV, at first blush the construct seems prefer it has crossed all its Ts and may even make a great prototype for a manufacturing unit sooner or later. In the event you don’t want the entire options that this charging station has, although, you’ll be able to all the time hack the automotive itself so as to add some extra superior charging options.
