5 1/2 tons? Is that a big battery? That seems like a big battery.
From The Drive, December 2:
Based on what we know about the Semi’s range and efficiency, the battery pack could have a capacity of 850 kWh.
It's official: the first electric Tesla Semi has been delivered to PepsiCo and Frito-Lay. Tesla held a delivery event Thursday in Sparks, Nevada, to commemorate the event, complete with a load of snacks carried by one of the Semis. Even though I wasn’t there in person, the show still gave me something to chew on.
During the event, Tesla CEO Elon Musk revealed that the Semi is rated for 500 miles of range with a fully loaded trailer, which meant that the battery pack inside the truck would have to be absolutely ginormous. How big, exactly, is unknown; however, Musk took to Twitter early Friday morning to reveal roughly how efficient the truck is, which helps me make estimations about capacity and weight.
Based on those efficiency numbers, a bit of napkin math shows just how large the battery pack might be. A rating of 1.7 kilowatt-hours per mile equates to a pack size of around 850 kWh, or around 8.5 times the size of a Tesla Model S Plaid's battery....
