To fill a car with gas, you generally just need a credit card or cash. To charge an EV at a DC fast charging station, you need any number of things to work—a credit card reader, an app for that charger’s network, a touchscreen that’s working—and they’re all a little different.
That situation could change next year if a new “universal Plug and Charge” initiative from SAE International, backed by a number of EV carmakers and chargers, moves ahead and gains ground. Launching in early 2025, the network could make charging an EV actually easier than gassing up: plug in, let the car and charger figure out the payment details over a cloud connection, and go.
Some car and charging network combinations already offer such a system through a patchwork of individual deals, as listed at Inside EVs. Teslas have always offered a plug-and-charge experience, given the tight integration between their Superchargers and vehicles. Now Tesla will join the plug-and-charge movement proper, allowing Teslas to have a roughly similar experience at other stations.
The Electric Vehicle Public Key Infrastructure, or EVPKI, has a good number of the major players on board, and it builds on the ISO standard (15118) to make it faster and more secure for cars to be authenticated and authorized to charge at stations. A whole bunch of certificates are in place at every step of the charging process, as detailed in an EVPKI presentation, and the system includes a Certified Trust List. With an open standard and authentication system, there should be room for new charging networks and vehicle makers.
Several years ago, General Motors and EVgo teamed up to build out a network of fast chargers for electric vehicles. As Tesla proved, giving your customers confidence that they won’t be stranded on a long drive with a dead battery really helps sell EVs, and GM’s sometimes-shifting target currently stands at deploying 2,850 chargers. Today, the two partners showed off their concept for an improved charging experience, which they say will come to a number of flagship charger locations around the US.
The most obvious thing to notice is the large canopy, co-branded with EVgo and GM Energy, similar to those found at virtually every gas station across the country. The gas station vibes don’t end there, either. Ample lighting and security cameras are meant to combat the sometimes sketchy vibes that can be found at other banks of (often dimly lit) fast chargers after dark, located as they often are in the far reaches of a mall parking lot.
And the chargers are sited between the charging bays the same way gas pumps are located, allowing a driver to pull through. Most fast chargers require a driver to pull in or back into the space even when the chargers are located to one side, a fact that complicates long-distance towing with an EV.
The chargers will be rated for 350 kW so that 800 V EVs can minimize their charge times. And while the announcement did not mention charging plugs, given GM’s adoption of the J3400 (originally NACS) plug from the next model year and EVgo’s embrace of the new connnector, it seems likely to expect both J3400 and CCS1 plugs on each charger.
“The future of EV charging is larger stall count locations, high-power charging, and designing around features that customers love—such as pull-through access, canopies, and convenient amenities. Through this next evolution of EVgo and GM’s esteemed collaboration, the future of EV charging is here,” said Dennis Kish, EVgo’s president.
“Ensuring that our customers have seamless access to convenient and reliable charging is imperative, and this effort will take it to the next level,” said GM Energy VP Wade Sheffer. “Through our collaborations with industry leaders like EVgo, we continue to innovate and expand customer-centric charging solutions that will meet the evolving needs of EV drivers across the country.”
The first site opens next year
There won’t be a fixed number of chargers at each location—the companies say most sites will have “up to 20 stalls,” with some locations featuring significantly more. We also don’t know where the sites will be—GM and EVgo say “coast to coast, including in metropolitan areas in states such as Arizona, California, Florida, Georgia, Michigan, New York, and Texas” and that the first location should open in 2025.
2025 was the original time frame for the full deployment of the GM Energy/EVgo fast charging network, which was also supposed to total 3,250 plugs by then—at least, that was the goal when Ars wrote about it in 2022. It appears as if the reduction in plugs freed up funds to pay for these fancier flagships.
That said, the network is not vaporware. EVgo and GM Energy deployed their 1,000th charger last summer and say they’ll reach the 2,000th by the end of this year. Additionally, the two are working together with Pilot Travel Centers to deploy another 2,000 chargers across the US at Pilot and Flying J travel centers—by the end of 2023, the first 17 of these were operational, with the goal of 200 sites by the end of this year.
