The Tesla Semi will carry a “small” 500 kWh battery

Announced during Battery Day, the new batteries manufactured in part by Tesla are gradually revealing their potential. Elon Musk had already indicated that these new so-called 4680 batteries would equip the Semi and the Roadster, he now reveals their capacity. And the least we can say is that this one is amazing. Indeed, according to the boss of the Californian brand, the Semi, should carry a 500 kWh battery. For comparison, a current 100% electric SUV such as the EQC or the Audi e-tron oscillates between 80 and 100 kWh.

On paper, a battery five times larger for a truck which should weigh much heavier than a family vehicle seems clearly insufficient to reach the respective 480 km and 960 km of the two versions of the Semi.

Ultra-efficient batteries

Elon Musk had already indicated in the past that the consumption of the Semi would not exceed 2 kWh per mile. According to a particularly clever calculation, it was therefore possible to estimate that the 300-mile version of the Semi would carry a 600 kWh battery, and that the 600-mile battery could be equipped with an accumulator of approximately 1200 kWh. But Tesla’s progress with 4680 cells seems to have been a big game-changer. Lighter and more efficient, these new batteries allow an even higher level of performance.

Obviously, it is the 300 mile version of the Tesla that will be equipped with this 500 kWh battery. It is also this first model which is scheduled for commercialization by the end of 2020.
