Tesla unveils a new structural battery pack, and Tesla threw a party for the locals to celebrate the upcoming start of production at its Berlin Gigafactory. Kids of all ages dug the carnival rides, the giant Tesla coils shootin’ out sparks, and the obligatory pumpin’ sound-and-light show.
For techies, however, the star of the show was Tesla’s new structural battery pack. A cutaway version was on display, clearly showing how the new 4680 cells are arranged in the collection. In addition, Tesla offered visitors a mini-tour of the plant, and some of the many innovations making their debuts here were on display.
Tesla unveils a new structural battery
Tesla held a party for the locals to celebrate the start of production at the Gigafactory in Berlin. Children of all ages dug carnival rides, giant Tesla coils sparked, and a mandatory pump-in sound and light show.
But for technicians, the show’s protagonist was Tesla’s new structural battery pack. A cutaway version was exhibited, clearly showing how the new 4680 cells are arranged in the group. Tesla offered visitors a mini-tour of the factory, revealing some of the many innovations that debuted here.
Tesla states that its 4680 cells offer higher energy density and better thermal stability than its 2170 cells. The company is currently producing them on a pilot line in California, and several suppliers are reported to be working on it. Next, scale them to mass production.
The new battery pack features a “cell-to-pack” design that does not use a battery module, making it easier and cheaper to manufacture. In addition, its structural strength allows it to be combined with Tesla’s huge integrated front and rear Underbody casting, further reduce weight, complexity, and cost.
Fans of Techie Tesla are enthusiastically analyzing the arcana of the new battery pack design by taking a closer look at the party’s pix. The cooling system for the new pack seems to be a bit simplified.
Like the 2170 pack, the cooling channels meander between the rows of cells, but it’s not clear if there is also cooling at the top and bottom. In addition, some people see signs that new packs are designed to be easier to recycle. This is Teslas. More and more emphasis is placed on battery life stages.
The Bottom Line
During a presentation, Tesla said that it would mount the seats directly on it and lower the body around them, significantly simplifying the assembly process.
All these manufacturing improvements are expected to improve the cost and efficiency of the Model Y significantly.
At the event, Musk said that Tesla is currently aiming to start Model Y production at Gigafactory Berlin next month.
At its Gigafest, a sort of country fair at Gigafactory Berlin, Tesla unveiled the latest version of the structural battery pack.
