The design of the Tesla Semi battery pack has leaked, and it reveals how Tesla fits a massive ~900 kWh pack in the truck.

Tesla unveiled the production version of its Tesla Semi class 8 electric truck and delivered the first units last month.

At an event, Tesla described an electric truck that could truly disrupt the trucking industry.

we noted that there were a few pieces of information that Tesla omitted from the event

that could really make a significant difference in the usefulness of the truck.

The two main missing pieces of information were the battery pack capacity

the weight of the tractor. Weight determines the load capacity since total weight with load and trailer is limited to 82,000 lbs.

More recently, CEO Elon Musk released a few details that allow us to confirm that

the Tesla Semi battery pack has an energy capacity of about 900 kWh.

The battery pack has never really been visible on the Tesla Semi prototypes

Frankly, that’s impressive because how do you hide almost 1 MWh pack inside a vehicle like that?
