The EV Charging Problem Is Getting Worse

It will get better, but until then, the dongles are killing me.

Last year, a great streamlining of electric vehicle charging infrastructure looked imminent. One by one, the major automakers committed to using the North American Charging Standard, or NACS, which was formerly Tesla’s proprietary plug. The moves would allow EV drivers of all stripes to use Tesla’s Supercharger network and would move the industry toward a single standard where things worked seamlessly. Earlier this month, GM joined the ranks of Ford and Rivian in having its vehicles officially able to visit nearly 18,000 Supercharger stations.

All of the GM vehicles built up to this point, however, carry the previous charging standard for non-Tesla EVs. You know what that means: dongles.

Drivers in combustion cars choose between regular, plus, and premium gas, but they don’t worry that they’ll pull into a station and the pump won’t fit their car. EVs, meanwhile, still have to deal with a mess of competing plug standards and confusing customer interfaces at charging stations. This situation is the inescapable result of a fast-moving, fledgling industry, yes. But the complexity is an annoyingly sticky barrier to EV adoption.

The adapter necessary to make a GM EV work with a Tesla plug, for instance, is available. But there’s a waiting list, and the piece costs $225 — effectively a $225 early adopter penalty for buying your EV back before everyone agreed on how to cooperate. When Ford transitioned to NACS earlier this year, it had difficulty extracting enough adapters from Tesla to meet the demand, dragging out the process for months for some of its EV drivers. GM had been slated to join the Supercharger network months earlier and could not because of the dongle delays.

Not all the eligible cars just work, either. After GM electric vehicles were welcomed to Tesla Superchargers, it turned out that lots of Chevrolet Bolts made in 2019 and 2020 (when they were the best-selling non-Tesla EVs) needed to visit the dealership for a software update before they could link up with a Tesla plug.

Software patches and dongles may be an annoyance, a kind of Band-Aid to make two systems that weren’t meant to work together play nice, but at least a quick fix is possible. A bigger issue for streamlining charging stations is that the locations of charging ports on EVs themselves are far from standardized.

All Tesla models have ports in the rear on the driver’s side; Supercharging stations are typically built for drivers to back in and then find the appropriate cord right next to their charging port. A Chevy Bolt’s port, however, is found on the driver’s side but on the front. A Hyundai Ioniq 5’s is in the back, but on the passenger side. When Rivian revealed the R2 and R3 designs, their ports were on the passenger side rear because the brand thought that location would fit into its existing network of chargers and make it easier to plug into street-side plugs. Then came an outcry from fans distraught at how difficult it would be to use a Tesla Supercharger if the port were on the wrong side and the cable had to wrap all the way around the back of the vehicle. Rivian changed its mind.

Thank goodness for that, because the situation at Superchargers is poised to get messy. I’ve been to ones where Tesla plugs were available, but I could not park my Model 3 within reach of one because other EVs parked incorrectly in order to plug in. Tesla’s lead engineer for the Cybertruck had to warn people not to use extension cords at Superchargers since that might lead to electrical shorts.

Some relief is on the way. In the coming years, most car companies will build the NACS standard into their electric vehicles, negating the need for expensive adapters and dongles. With so much emphasis on using the Supercharger network, it’s likely the brands will feel pressure to follow Rivian’s lead and just put the port where Tesla puts it.

But then there’s the last piece of the puzzle: the interface. Tesla beat the competition at charging not only by building a bigger and far more reliable network, but also by inventing a seamless way to pay for electricity: When you plug in, the system knows it’s your car and charges the credit card on file. Non-Tesla drivers are beginning to experience this convenience when they stop at the Supercharger.

Competing systems, though, rely on a variety of phone apps that may or may not work, especially in places with spotty cell coverage. Tech companies are trying to solve this problem with, you guessed it, AI. Revel, which used to offer rentable mopeds around New York City, has tried to reposition itself as an EV charging company. It just partnered with a computer vision company to announce a kind of facial recognition system for your car so that the charging station knows it’s you.

Of course, one could just copy Tesla’s idea and have the charging cord auto-identify each vehicle, or even simply install a camera to read the car’s license plate instead of overcomplicating the basic task of IDing a car. But those solutions don’t use the magic technology of the moment.

Tesla Is Now a Culture War Totem (Plus Some AI)

The EV-maker is now a culture war totem, plus some AI.

During Alan Greenspan’s decade-plus run leading the Federal Reserve, investors and the financial media were convinced that there was a “Greenspan put” underlying the stock market. The basic idea was that if the markets fell too much or too sharply, the Fed would intervene and put a floor on prices analogous to a “put” option on a stock, which allows an investor to sell a stock at a specific price, even if it’s currently selling for less. The existence of this put — which was, to be clear, never a stated policy — was thought to push stock prices up, as it gave investors more confidence that their assets could only fall so far.

While current Fed Chair Jerome Powell would be loath to comment on a specific volatile security, we may be seeing the emergence of a kind of sociopolitical put for Tesla, one coming from the White House and conservative media instead of the Federal Reserve.

Climate Tech Is Facing a ‘Moment of Truth’

The uncertainty created by Trump’s erratic policymaking could not have come at a worse time for the industry.

This is the second story in a Heatmap series on the “green freeze” under Trump.

Climate tech investment rode to record highs during the Biden administration, supercharged by a surge in ESG investing and net-zero commitments, the passage of the Infrastructure Investment and Jobs Act and Inflation Reduction Act, and at least initially, low interest rates. Though the market had already dropped somewhat from its recent peak, climate tech investors told me that the Trump administration is now shepherding in a detrimental overcorrection. The president’s fossil fuel-friendly rhetoric, dubiously legal IIJA and IRA funding freezes, and aggressive tariffs, have left climate tech startups in the worst possible place: a state of deep uncertainty.

AM Briefing: Overheard at CERAWeek

On the energy secretary’s keynote, Ontario’s electricity surcharge, and record solar power

CERAWeek Loves Chris Wright

Current conditions: Critical fire weather returns to New Mexico and Texas and will remain through Saturday • Sharks have been spotted in flooded canals along Australia’s Gold Coast after Cyclone Alfred dropped more than two feet of rain • A tanker carrying jet fuel is still burning after it collided with a cargo ship in the North Sea yesterday. The ship was transporting toxic chemicals that could devastate ecosystems along England’s northeast coast.

THE TOP FIVE

1. Chris Wright says climate change is a ‘side effect of building the modern world’

In a keynote speech at the energy industry’s annual CERAWeek conference, Energy Secretary Chris Wright told executives and policymakers that the Trump administration sees climate change as “a side effect of building the modern world,” and said that “everything in life involves trade-offs." He pledged to “end the Biden administration’s irrational, quasi-religious policies on climate change” and insisted he’s not a climate change denier, but rather a “climate realist.” According toThe New York Times, “Mr. Wright’s speech was greeted with enthusiastic applause.” Wright also reportedly told fossil fuel bosses he intended to speed up permitting for their projects.
