New EV owner here. We charge at home so I don’t need to use them, but stores nearby have chargers. I tried them to see how they work. They are often broken.
One store has a Volta charger (free!). It worked great the first time; the next time I went it was broken.
Walmart has an Electrify America fast charger. The first time I went, 1 of 3 was not working. The next time I went, 1 of 3 was not working, but it was a different one.
Was I unlucky, or are these charging networks unreliable? Has it been getting better or worse over time?
I think my experience is skewed by not having a dcfc capable car. I charge exclusively j1772. And use plugshare to find the chargers.
In 5 years of ownership I've charged not at home probably 150 times. Of those times I would say I couldn't get the charger to work maybe 20 times. And of those 20 probably half didn't have any other option at the same location that I was able to get working.
Again this is skewed by filtering through plug share and not even attempting locations that have comments claiming they're broken.
