I’ve been tracking my DCFC sessions for four years. I have made hundreds of stops at DCFC in my ~90,000 miles of driving.Depending on the source, Tesla seems to have to the most reliable network, compared to say EA, I’ve yet to see the local superchargers to be offline, but same can be said for the L3s at the Electric company parking lot (those have been there longer), I can say the same for the Mercedes branded ChargePoint DCFCs at bucees, but most L2s here (blink) are offline, and 40% of the times I’ve visited an EA DCFC 2 or more have been offline.
The the initial point, we were looking to see how feasible the event on the 20th would be, so I checked the route on Google, not a single SuperCharger appeared, then I did a route in the Chevy app and all three stops were SCs
I’ve have seen down plugs about 15% of the time I’ve used EA.
I’ve have seen down plugs about 50% of the time I’ve used brand-T.
The difference is that brand-T usually has 12 or more charging plugs at its stations, so a station with two or more offline plugs doesn’t stop charging for most users. But EA usually has 4 or 8 plugs at its stations, so even one offline plug has a greater overall impact on the users of that station. EA has significantly improved over the past two years and I have only encountered one EA station with an offline plug in the past year.
