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?
They are genuinely more reliable. Having more stalls does help for when there’s issues, but they have 99.96% uptime across the entire network. I’ve had to move stalls once in my almost 3 years of ownership.
They also have their own service people that travel to chargers to fix them, where Electrify America hires local electrical contractors that may not be experts on DC Fast Charging equipment.
Edit: ran some numbers and I’ve charged 109 times on Superchargers. One failed session. I live in the rural Midwest/South so it’s not like I’m in EV heaven either.
