Then there's the plug business. While it's true that not all EVs use the same plugs, the reality in 2022 is that there is, in fact, a de facto standard across the US that every new EV sold today uses, with one large and one small exception. This means that it doesn't matter if you drive a Volkswagen ID.4, a Mercedes-Benz EQS, a Nissan Ariya, or a Kia EV6 (to name but four)—all of them use the same plugs and can charge at the same chargers.

Level 1 and level 2 chargers both use the same plug, the SAE J1772. It's a relatively bulky thing with five pins and is rated for everything from 1.4 kW to 19.2 kW.
The de facto standard level 3 plug is the Combined Charging System (CCS) Type 1. It's a much bulkier plug since it combines the already big J1772 plug with two large DC pins below, all attached to a thick and heavy cable. If you buy a new EV today from almost any car maker, it will use CCS Type 1 to fast-charge.
The big exception is Tesla. The company deployed the first of its Superchargers—its brand name for level 3 chargers—in September 2012, while the rest of the auto industry was still getting its act together. So it went with a proprietary plug of its own, a much more elegant and much lighter design. However, even this may change. (In late 2022 this plug was renamed the North American Charging Standard, or NACS.)
The European Union isn't crazy about companies locking customers into proprietary plugs, and European Teslas actually use the European version of CCS, Type 2. Here in the US, federal funding for charging networks requires that the chargers adhere to industry standards, which has led Tesla to explore the idea of adding CCS Type 1 plugs to Superchargers at some point in the future.
The small exception is the Nissan Leaf, which used a rival Japanese charging standard called CHAdeMO. This offered an even bigger, even more cumbersome connector. What's more, it required an EV to have two separate sockets, one CHAdeMO and a second J1772, unlike CCS, which includes the J1772 port. CHAdeMO remains a thing in Japan, but the only EV on sale in the US that still uses CHAdeMO is the Nissan Leaf, and that model is reportedly not long for this world. Consequently, CHAdeMO chargers may be harder to find, but every Electrify America location should include at least one CHAdeMO plug.
Of course, in order to charge an EV on the road, you have to be able to find a public charger. And unlike gas stations, charging stations don't often advertise themselves with large illuminated signs that are visible from miles away. That means a road trip requires an extra planning step. But don't worry—it's not nearly as difficult as having to print out MapQuest directions like we used to do, never mind the olden days of road atlases.
Odds are good that the EV you're driving will know where all the chargers are and will be happy to navigate you to them via its onboard navigation system. Depending on the car, it might even know the status of the actual chargers there and may even begin heating your battery to ensure the quickest fast charge once you plug in.
But, many EV drivers rely on third-party smartphone apps, including PlugShare and A Better Route Planner (although this one requires a subscription). Usually, these apps let you plan routes, taking into account the battery capacity and efficiency of the EV you're driving, its starting state of charge, and how much charge you want remaining when you arrive at your destination.
It's also useful to download the apps for charging networks, as those apps will provide the real-time status of chargers—whether they're functional, in use, or broken. If you're in a pinch, especially if you're driving in rural areas, some dealerships will let you use their level 2 chargers. An app like PlugShare will list those, along with check-ins from users that have successfully charged there.
You can even use the US Department of Energy's database of EV charging stations website (or its smartphone apps), which as of press time contains 49,430 level 2 and 3 locations in total, of which 6,415 are level 3 fast chargers.
Expect those numbers to grow significantly in the next few years as the federal government spends $5 billion on fast chargers located roughly every 50 miles across the Interstate Highway System.
