  • I’m curious what the viability is to set up a new fast charging station.

    The one thing I know from a friend who did some research was that selecting the “box” was by far the easiest and cheapest part.

    Getting near-Gigawatt electrical service was NOT easy and heavily restricted the location that it could cost-effectively be installed.

    Also, getting permits from the city may be the reason Tesla doesn’t have it yet as they city may be stingy in this particular densely populated area.

    Also challenging is leasing the parking spots, as this kind of use reduces the number of zoned parking spots available for buildings and most in very urban areas are built right at zoning minimums, so they don’t actually have parking spots that they can legally give up. (which is why you see a bunch in parking ramps in urban areas).

    I’d expect half a million $$ in investment or so. Payoff is like 20 years.

    My friend bailed after getting a bunch of quotes for service. It wasn’t even close to profitable unless you HAPPEN to have a free parking location with high-voltage power already adjacent (which is decidedly rare in major cities) and major government subsidies.


  • Yeah, they’re basically prototypes.

    The first generation of battery from most EV companies had a silly high failure rate.

    Tesla, GM, Nissan, Audi, etc all had really high failure rates in the first generation of cars. In the 30% range for GM and Nissan, in the 5% range for Tesla.

    The motors had high failure rates (again in their first generation). Similar rates.

    They’ve also added high-complexity parts like heat pumps in their first automotive iterations.

    I expect all of this will become more reliable once they’re more established.

    It’s plausible they already are. From what I’ve heard the failure rate on Tesla parts (battery, motor, etc) dropped significantly after the first revision in 2016 and again after 2021. 2013 battery was a 5% failure rate, while the 2017 battery was a 0.2% failure rate (roughly) from the 2022 data I saw.

    I expect that progress continues and third our fourth generation EVs will be decidedly more reliable than ICE cars.


  • This is why Tesla formerly implemented idle charges and is currently implementing congestion charges for users charging beyond 90%, and congestion warnings that automatically reset cars to 80% (but can then be reset by users) at high-utilization chargers.

    It’s also why outages like “2/4 plugs are broken at this location” (which is shockingly common at some brands of chargers) isn’t acceptable.

    Finally, a system that detects when a charger is full and automatically directs users to another nearby charger is very helpful, especially given the scenario that sometimes there are multiple nearby chargers, but one gets more popular than others due to location.

    Tesla manages all of these.

    I’m not sure why Tesla is the only one who can do this right, however, it’s a bit baffling.




  • The EQB is a short-range car with slow charging compared to something like a Tesla or the new Kia.

    Chargers for the Mercedes are half as available as they are for a Tesla Model S and the range is barely half and it charges at half the speed. Overall, you’d have had a much more pleasant experience in a Tesla.

    Then you chose to charge to 100% (which means almost 1 hour charging stops, yikes).

    The “cannonball run” across the US is won by a Model S, which drives down to 5% and then charges up to about 60%. Above that, it slows down a lot.

    That makes for 15-20 minute charging stops.

    At least you didn’t end up in a Mazda or a Chevy Bolt, they’re far worse for road trips than the Mercedes, but the Mercedes is a decidedly bad road trip EV.







  • The experience with CCS is rarely that you’re stranded.

    My experience has generally been… pull into an EA charger with 4 handles. 2 are outright broken, one is finnicky and/or slow and the last one works fine.

    That’s… not ideal, but it’s not show-stopping. It can result in some lines and angry visitors when people show up, especially since EA is kind of bad at reporting dead cables in their app.
