If the only criteria is dependability of individual chargers, OK, probably so.
You hit the nail on the head. Coverage doesn't mean much if you can't count on the site when you pull in.
That's been EA's problem for years, and it compounds. Their sites are small with often 4 to 6 stalls on average and in my experience at least one is always down, sometimes two. So a 6-stall site is really a 4-stall site. Then the stalls that do work often don't deliver, 90% of the time at EA I'm looking at "charging limited by charger."
Does the charger work? Yes.
Is it reliable? No.
And the ripple effect is real, cars sit longer because they're charging slower, the line grows, everyone waiting gets frustrated. Tesla has broken stalls too, but when a site has 20 of them, two down and a couple slow ones barely register.
I'd also argue EA's reliability is a big part of why nearly every automaker in the US jumped to NACS. If the largest CCS network had been dependable, there would have been far less pressure to adopt Tesla's connector and get access to Superchargers. Automakers heard the complaints from their owners loud and clear.
For context. That's what the network score on the LucidTracker charging map measures, not "does it charge," but "does it deliver what it advertises." Each fast-charge session logged by a LucidTracker+ or Trailblazer car gets scored on the peak kW the car actually pulled versus the station's advertised rate (capped at the car's own max, so a 250 kW car at a 350 kW stall isn't penalized). It also only counts sessions that started at 40% or lower, so someone plugging in at 60% and topping off to 100% doesn't drag a network down with a taper-limited peak, the car has to have had a real shot at hitting full speed. Delivered-over-advertised counts as met, never as bonus. A site that advertises 350 kW and works fine but cars are peaking at 100 kW is exactly what pulls a score down, and that pattern is showing up on EA far more than anyone else. It's a small dataset still, but that's the same story I've lived for five years.
EA has been so bad for me in California that I simply can't trust them anymore. I hadn't touched EA once since getting the Gravity, but at Monterey Car Week the EA site was just down the road while the nearest Supercharger was a further drive, so I figured I'd give them another shot. Six stalls, two broken. Got lucky that someone was pulling out so I could grab a spot. Then came the whole song and dance, plug in, nothing, unplug, plug in again, repeat, before it finally started. Then when it finally started I was speed limited for the entire session. With Tesla, I plug in and it just works, first attempt, every single time (for me at least). It's a night and day experience. I'll take a 225 kW cap on a Supercharger any day over rolling the dice at EA and getting 100 kW.
