Last year, Tesla announced it was producing an electric semi truck capable of carrying cargo across the country without burning any fossil fuels. While the vehicle itself is nowhere near ready for production, Elon Musk has that a prototype vehicle has already made that cross-country trek using the company’s existing Supercharger network.
Tesla’s Supercharger network is a series of fast charging stations designed to provide power to Tesla owners driving around the country, but they were never designed to supply the power needs of large vehicles like the Tesla semi. Instead, Tesla plans to build another network of Megachargers, which are designed with those trucks in mind.
However, the Megachargers are just a proposal right now, which means the prototype semi has to rely on the less powerful Superchargers for its cross-country journeys. As a workaround, the driver of the semi brought several extension cables so the truck could charge from several Supercharger stations at once.
Thanks to those extension cables, the prototype semi traveled from the company’s Fremont factory in California to Arkansas, almost 2,000 miles away. According to Musk, the truck made the journey alone, without any accompanying vehicles. That’s a good sign for the semi’s future, although there’s still a lot for Tesla to do before the first production truck hits the road.
