GM and EVgo To Build 400 Ultra-Fast EV Chargers Across the US (insideevs.com) 77

An anonymous reader quotes a report from InsideEVs: General Motors is joining forces with EVgo, one of the biggest electric vehicle charging operators in the United States, to build 400 ultra-fast DC chargers nationwide to support the growing number of battery-powered cars hitting U.S. roads. To be clear, these are individual stalls, not charging stations. However, the two companies describe the new locations as "flagship destinations" which will feature 350-kilowatt DC chargers, ample lighting, canopies, pull-through spots and security cameras. Most locations will feature up to 20 ultra-fast charging stalls, but some will have even more -- good news for those crowded holiday road trips. GM and EVgo said the fancy new stations would be located near shopping areas offering dining, coffee shops and other amenities.

We don't know exactly where the new stations will be built, but EVgo mentioned that the "flagship destinations" will be deployed coast to coast, including in metropolitan areas in states like Arizona, California, Florida, Georgia, Michigan, New York and Texas. The stalls will be co-branded EVgo and GM Energy -- the automaker's charging and energy management division. The first new "flagship station" is expected to open next year. The new stalls will make use of EVgo's prefabrication approach which can reduce the total cost of a new station by 15% and the deployment time by 50%. Similar to Tesla's prefabricated Supercharger stalls, EVgo's ready-made structures come with stalls and accompanying equipment already mounted on a metal base plate which is transported from the factory to the charging site.

      That makes sense. A 'destination gas station' makes comparatively more sense for a longer (charging) stop than for just a quick gas stop.

        Technically ti's the other way around. Buc-ee's is convenience store that happens to sell gas, not a gas station that sells other stuff. (Gas stations make very little profit - all the profit is in the convenience side of things).

        Of course, they have many gas pumps because filling gas is basically the chore part of the equation - you start the pump then go into the store and spend half an

    • Makes sense to me. Tesla is already installing Supercharger stations at Buc-ee locations.

    • Buc-ee's has been expanding into Florida in the last couple of years; their stores in St Augustine & Daytona have a long row of Tesla chargers to go with the 30-odd gas pumps. Don't know if they're retrofitting them into their existing footprints but I'm guessing yes.

      It's disappointing that they are installing old technology though. We have had 400kW chargers deployed since last year.

      Current gen Xpeng cars are getting close to 350kW peak, and will sustain around 300kW for much of the charge cycle. The 400kW chargers split that between two vehicles, with the first to plug in getting priority, so even an additional 50kW helps.

      Maybe they don't have 800V cars that can take advantage of it.

        Faster is almost always better but you do get into diminishing returns. Kind of like how people stopped buying PCs and phones just to get a faster CPU.

        Below 100kW is really annoying if you don't have something else to do for a reasonable amount of time such as a meeting at a business complex.

        Over 100kW is ok if you combine it with a meal break so ok for a road trip.

        The real appeal of the 250kW+ charging is the traditional gas station stand around and wait experience that will appeal to people who

      Not even remotely that many. The vast majority of charging for the population is done at home or at L2 charging stations. These kinds high power ultra fast chargers are designed for long range driving only. Why would you need 400000 high speed chargers when there are currently less than 200000 total gas stations in all of America and when oil companies themselves estimate a 90-99% drop in service station use as a result of EVs not being charged mid-trip?

      • My office has L2 chargers in the parking lot and gives us 4 hours/day of free charging. The fast chargers are going in mainly along the interstates and major roads for drivers taking longer trips. Some of the big-box stores are getting into the game on the assumption you're spending 20-25 minutes shopping and want to 'top up' while you're there. The mall just down the road has an eight-stall charging station, half of them DCFC.

          • it would take 12 hours to fully charge a modern EV.

            I guess but if we reframe it knowing that on avverage you get 3mi/kwH and shop for 1/2 an hour, that's 3.25kwh or 9.75mi.

            That basically the grocery store providing you free gas for your trip to get there. If they offered this with actual gasoline I feel like everybody and their mother would be lined up even to get a free 1/2 gallon every trip.

        • The fast chargers are going in mainly along the interstates and major roads for drivers taking longer trips.

          My point exactly. You're not going to install twice as many fast chargers on interstates as there are gas stations in the whole of America. Look at the EU, currently 5+ years ahead of America when it comes to EV adoption. And in all of the EU there's less than 10,000 of these ultra fast chargers out of some 700000 total.

          No one needs 400000 fast chargers in America in the coming decade.

        I'm on your side, but your post is just as misleading. You can't compare stations to individual chargers, you have to consider total locations AND number of vehicles served per hour. Given that there are "less than 200000 gas stations", perhaps you could assume that 100000 EV fast charging stations may be enough, but where 1 gas pump could serve 10 vehicles an hour, a charging bay may serve only 1-2. That would suggest 500,000 charging stations could be needed. There's your number. Of course, that assu

Many apartments already charge for parking and more for covered parking, so why wouldn't they add another tier with EV parking? Level 2 charging is fine for overnight and the chargers aren't expensive.

            I can't charge at home. That doesn't mean I don't use destination charging. I have charged my car twice this year mid trip. Twice. In 9 months. All my charging is destination charging with L2 chargers (which is far cheaper than DC fast charging).

            I would not buy a PHEV if I was not going to plug it in regularly for the immediately foreseeable future. The battery might corrode/degrade for never being used and I am paying extra for that battery capability compared to an all-ICE vehicle.

            I think the third party L2 charging solutions, such as Invisible Urban Charging, will address much of the charge where you park needs. Basically they offer apartment and car parking building owners a charging solution for low cost and near zero effort in return for a profit share on the operation. The people parking there get charging at a lower cost than super charging and the parking owners get some extra income for little effort or hassle. Basically a win-win.

          And welcome back to my point. No one here is talking about L2 charging. The existence of L2 charging only reduces the use of L3 charging - i.e. we don't in any foreseeable future need 400000 such points in the USA. That would be 2 orders of magnitude higher than what i

The density of gas stations per unit area is not movitaved by total requirement for throughput much, nor is it going to be for charger stations.

Even with the older chargers around the 100kW level you can get a decent amount of road trip range in 20 minutes. With the 350kW they are talking here many people could be done charging in about 10mins. For those people the charging experience is on par with stopping at a gas station.

        Actually the supercharger usage can probably be broken down into two groups:

        Firstly the road trippers you mention. In this case often the stop is combined with other break needs so even 'slower' charging at 125kW is ok, but faster is always nicer. There is always going to be a need for these so more is good but once you get up the limits of what most 400V cars can handle more kW is probably less important that toilets, food and shelter from the weather.

    • How many total would be needed in the US? 40 000? 400 000?

      We're all nerds here, so let's do the math:

      America has 200k gas stations, with an average of six pumps each, for 1.2 million fueling points.

      But gas cars must go to a gas station, while EV owners do 95% of their charging at home.

      TFA says these chargers are 350kw. My EV has a capacity of 80kwh. So that's 15 minutes of charging. But my 9-year-old EV isn't capable of fast charging. So, let's say an average of 30 minutes of charging vs. 5 minutes to refuel a gas car.

      1.2M * (1 - 0.95) * 30/5 = 360,000

      • ...while EV owners do 95% of their charging at home.

        While that figure might be true for present EV owners, what about all the millions of car owners who would like to make the switch to EV, but cannot charge at home or work?

        Until there's a great many more convenient charging points available, these millions of ICE drivers can't - not won't, but can't - make the change to EV.

These can be cheaper, relatively low-power units, say 3.8kW (240V @ 20A) as the car is going to be left there overnight - it doesn't need to charge in 3 hours. There is probably already spare capacity on the streetlight circuits as they were originally specd for sodium lights which have since been swapped for more efficient LEDs.

            • by ukoda ( 537183 )
              My understanding is in some states new car parks over a certain size must be prewired for L2 EV charging. So future car park operators falling under these regulations will be able to cheaply roll out L2 charging in sync with the demands of EV car park users.
        • by ukoda ( 537183 )
          The improvements in this area go mostly unreported as they are not the big flashy installs. There is a lot of L2 charging going in places where people park long term, such as car parking buildings and apartment car parks. This is happening because the owners of such parks can see an extra income source and with third party operators appearing that make this low hassle for park owners the demand is outstripping supply at the moment.

        "But gas cars must go to a gas station, while EV owners do 95% of their charging at home."

        Any stats about EV usage today don't matter. All that matters is what the stats would be if EV adoption goals were met. NO way that number remains as high as 95% as adoption increases, both because more drivers will not have access to home charging and fewer drivers that drive long distances will avoid EV. Right now, homes can consider EV as a second car and/or if they have a private garage and do not road trip too

      • Whether it was the infrastructure bill or the IRA, the standard set in law is one station [not necessarily a single unit per] per 50 miles of interstate.
        Per google, there are approximately 47-49k miles of interstate. There's also a statutory limit on the number of miles [in 1956 it was 41k].
        So, if we assume that there's a lot of redundancy like California's I-880 vs I-580 vs I-280 included in that number, let's make it 100 miles.

      Putting aside your worse case numbers the power needed is still high. That is why the ""Hello, power company? I need a X megawatts" call is made at the early stages of planing, before anything is purchased. The good news is the heavistly used highways often have power grid distribution running parallel to them making highway adjacent supercharging less of a drama than you might expect of such high power demands.
  • Roughly, how many minutes does it take to go from nearly "empty" to fully-charged? Same question for the current crop of chargers.
    • It depends on a number of factors, not least the actual capacity and design of the battery as well as the capacity of a given EV's charging circuitry.

      In addition, the "fast" part of the charge cycle is only between 20% and 80% of a battery's capacity - below and above these limits charging has to take place more slowly to (a) preserve the life of the battery, and (b) avoid catastrophic failure. This is why EV makers quote charge-times only for 20%->80%, although the vehicle range is always quoted based o

      I don't know because I have only been using a BEV for 4 years and 0 to 100% is not a real world use case. You usually plan to charge to 100% before a road trip, while the car is parked up not in use. On the road you would typically make a stop before falling below 20% and finish charging at around 80%. There are a lot of variables in the mix but in my case the car knows when it will stop to charge so preconditions the battery. So my use case it is typically 15 to 25 mins to charge on a long trip which m
  • OK, so let's accept the idea that EV owners can charge at home(?). So the best use for commercial charging would be for trips AWAY from home, obviously.

    So let's just put these magical charging stations on the interstates only. Today there are about 41000 miles of interstate in the US, so we can have one every 1000 miles or so.

    Alright, lets maximize availablility by locating them at Inersections and exchanges as much as possible. Great, now wer're down to only 800 miles between stations.

      Around here most interstate highway rest-stops have 4-8 CCS chargers as well as 10+ NACS. These are spaced out every 40-80 miles or so if you've got a 200mi+ range on your EV you are never in danger of being stranded. On state roads there's usually a fast charger in one of the big box store's parking lots or at a hotel.

      Try playing with a EV charging app or even Google maps. You will be surprised how many charging locations there are already. All right much of it is the older 50kW chargers that are usable but annoyingly slow, but they are common and will get you by in a pinch. The good news is a lot of chargers around the 100kW+ range are getting deployed and are fast enough to be useful.

      The thing is if you haven't been looking you won't see many of them as they are pretty low key and don't take up much space. For e
  • WOW - a whole 400 over the entire country? There's probably 400 gas stations in one city. This isn't going to move needle at all.
  • Here in Silicon Valley ebikes and scooters have a presence. Also, 110-volt chargers could also charge mobility devices for people with physical disabilities, and also offer changing in case of a disaster. Placing 110 volt chargers in cities just makes sense.
  • As with gas stations, being profitable is about location. Sub-optimal locations need zero support and zero maintenance, or they need something else to profit from like a little convenience store.

  • "Ultra-fast" means, according to the article, 350 kW. All these 400 chargers will be able to give 140 MW of electricity. Caloric value of gasoline is about 45 MJ/kg. So, all this power is comparable with 5 liters of gasoline per second. Standard fuel pumps are able to give 50 l/min. So, all these "400 ultra-fast chargers" are equal to 6 standard fuel pumps or one small gas station.

No spitting on the Bus! Thank you, The Mgt.
