The basic version of the Tesla Semi truck will receive a traction battery with a capacity of 500 kWh

Introducing the Tesla Semi long-haul tractor in 2017, Elon Musk announced his intentions to endow it with the ability to drive with a load on a single charge from 480 to 800 km. It was expected that this would require a traction battery with a capacity of 600 to 1000 kWh. In reality, the basic version of the Tesla Semi will be content with a smaller battery capacity.

Elon Musk admitted this in a recent interview with Joe Rogan. According to him, if light electric cars are content with batteries with a capacity of 100 kWh, then Tesla Semi will need a 500 kWh battery. At least, if we talk about the basic version of the tractor, capable of transporting goods over a distance of 480 km, then this estimate is quite adequate. Such efficiency will be achieved through the use of battery cells of a new standard size 4680. It is the beginning of their mass production that will make it possible to put Tesla Semi on the conveyor. The first serial copies of tractors will appear this year, but mass production will not be possible until next year.

As Elon Musk previously noted, the Tesla Semi traction battery will become part of the power structure of the truck frame. In addition to the payload, the truck will also have to move a fairly heavy traction battery, so the greatest attention is paid to increasing its efficiency. As Musk recently admitted, a truck will require five times more battery cells than a Tesla light electric car, so the start of mass production of the Semi is tied to the emergence of the new size 4680. The assembly of the Semi trucks will begin at a plant in Texas, which is now under construction. In small quantities, they may begin to be produced in Nevada.
