I remember using this before the internet popped off with facebook and twitter, I was into things way before everybody else talking to adults. I can use technology today and pick it up easy. Because charging is not instanteous, there could be a que at a site, being able to lookup the status of a charger before you arrive on your phone. I can read this graph and know what is going on with my car. When they say J-1772 connector, I know that is AC that is inverted in my car versus a DCFC that inverts AC from the power company to DC. I understand there are no AC batteries and this is why power has to be inverted to DC. AC induction motors are used so there is another inverter used.
Understanding the difference betweeen AC and DC, what connnector is doing what to the car. I understand how inverters work and can graph AC vs DC power. It is the same thing with solar power, it is much more complex. I think some guy created some app to simplify things, I think people don't understand and will attack the technology because of their limited abilities. I sometimes forget to look at things from your perspective.
This guy that did not charge his car at a hotel can pull this information up on his phone to verify that his car is charging. I would have intuitively done this. This is not for the feeble minded. I had one guy approach me while EV charging gay talking in a white Ford car, I talked to him like a child walking him through everything, he still did not pick it up.
