My hypothesis is that "older" chargers (those installed pre-2020 or so) didn't have their capabilities taxed very much, since they were mostly charging Bolts and Leafs. When high-powered cars came along, I think the power electronics, which were probably underspecced to begin with, started degrading quickly.
Now I don't know why the new BTCPower chargers installed by EA or the Delta chargers installed by EVgo are failing so quickly. I've tried to ask numerous people in the chain about reliability issues, but everyone seems to be very vague about the root cause of the issues. I'm pretty sure Delta chargers are used in Europe, and the newer Tritium ones are as well (the older 50kW units seem universally crappy) - so why does North America seem to have so many issues?
So my issue is this: Yes, EA sucks at fixing chargers, but why do they need constant fixing? I don't doubt the conditions the chargers are exposed to are pretty rough, but it seems that they keep failing at any weather - cold, hot, dry, wet. I also understand interoperability problems with CCS cars (and a lot should be caught in testing), but this isn't that. Chargers are constantly derating or completely dead.
