The US Sold 400,000 EVs Last Year - But Has Only 6,000 Fast Charging Stations

As the price of gas and concerns about global warming, fires, extreme weather and flooding push more people to buy electric vehicles, the relative dearth of charging stations is both a bottleneck - and a business opportunity. JL 

Andrew Moseman reports in MIT Technology Review:

The US has 150,000 gas stations for its fossil-fuel-burning vehicles. Despite the rapid growth of all-electric vehicles in America—400,000 were sold in 2021—the country has only 6,000 DC fast electric charging stations. (It has more than 48,000 charging stations of all kinds.) A glance at America’s charging map reveals charging deserts. Large cities have a growing number of fast chargers, but not nearly enough to accommodate EVs. Away from cities, these chargers are strung along interstate highways. They are nearly nonexistent in rural America. (But) “Even the fastest Tesla supercharger is going to take 15 minutes to put a couple hundred miles on the vehicle,”

The United States has around 150,000 fuel stations to refill its fleet of fossil-fuel-burning vehicles. Despite the rapid growth of all-electric vehicles in America—400,000 of them were sold in 2021, up from barely 10,000 in 2012—the country has only 6,000 DC fast electric charging stations, the kind that can rapidly juice up a battery-powered car. (It has more than 48,000 charging stations of all kinds.)

A glance at America’s charging map reveals an abundance of charging deserts. This makes sense, as EVs still represent less than 3% of new car sales. Large cities have a growing number of fast chargers, but not nearly enough to accommodate a major influx of EVs. Away from cities, these chargers are strung along interstate highways closely enough to allow electric cars safe passage. Otherwise, they are nearly nonexistent in rural America. And EV stations have a problem that gas stations don’t: “Even the fastest Tesla supercharger is still going to take 15 minutes to put a couple hundred miles on the vehicle,” says Jeremy Michalek, a professor at Carnegie Mellon University and director of its Vehicle Electrification Group

Michalek says American charging infrastructure lags far behind what’s needed for the whole country to transition to electric driving. On the bright side, there is time to catch up, because not all Americans will embrace EVs at once. Most early adopters were those with access to a charger at home in their garage or parking space. Those owners can wake up with a full battery and only need to rely on public chargers when they leave town on an extended trip. But as the country gets to higher levels of EV adoption, the current infrastructure won’t be enough. That is why Michalek says the US needs to prioritize bulking up the number of chargers at rest stops along well-traveled highways, especially as more people pile into electric cars for summertime road trips.

“As we get to higher levels of EV adoption, if we don’t have enough chargers for peak demand, the wait times are going to be unlike what we see with gas stations,” he says.

 

Charging dead zones will loom larger as more Americans consider an EV. Renters who do not have the option to install a home charger will be hesitant to go fully electric until they can feel confident a public plug will be there when they need it. And as more households drive only electric vehicles, it will be crucial that people can get to all the places they need (and want) to go.

The infrastructure bill that passed in November 2021 earmarked $7.5 billion for President Biden’s goal of having 500,000 chargers (individual plugs, not stations) around the nation. In the best case, Michalek envisions a public-private collaboration to build a robust national charging network. The Biden administration has pledged to install plugs throughout rural areas, while companies constructing charging stations across America will have a strong incentive to fill in the country’s biggest cities and most popular thoroughfares. After all, companies like Electrify America, EVgo, and ChargePoint charge customers per kilowatt-hour of energy they use, much like utilities.

Most new electric vehicles promise at least 250 miles on a full charge, and that number should keep ticking up. The farther cars can go without charging, the fewer anxious drivers will be stuck in lines waiting for a charging space to open. But make no mistake, Michalek says: an electric-car country needs a plethora of plugs, and soon.

I assume since the research is so easy to do that you purposefully haven't done it or are hiding it for some agenda-pushing that I don't know about.

301,000 of those EVs sold were made by Tesla. There are 30,000 Tesla Superchargers in their network. You can easily traverse the country on their network and people do it all the time. Personally, I've driven from Boston up to Ottawa as easily as I drove my gas-powered car back in the day.

Yes, it took fifteen minutes to get back up to 240 miles on the range-o-meter at that Supercharger. I cannot remember the last time I stopped after more than two hours of driving that my passengers (at least) didn't walk, stretch, find a snack, and use the bathroom and be ready to roll in LESS than fifteen minutes. So that point is really moot to me.

Very little of American driving behavior includes rural areas *unless* they are driving from home. In other words, for electric cars which are charged at home every night, it is a non-issue. You start the day with 300 miles of range, and in a single day you very, very rarely (three times a year?) go beyond that. If you do, you are usually on an Interstate for some portion of it and the charging network (for 3/4 of the cars sold last year in the United States) is robust on the Interstates.
