Tesla’s up coming generation of vehicles like the Cybertruck and the Designed-in-Texas Model Y will likely be built with a structural battery pack. Together with the company’s 4680 cells and megacasted elements, Tesla’s integrated battery system is expected to strengthen its vehicles’ mass and vary drastically.
During Battery Day, Elon Musk stated that the use of structural batteries on electric powered vehicles could be compared to how passenger aircraft finally used their wings to retailer gasoline. In the case of airplanes, the pounds of the gasoline in fact provided rigidity to the wing, decreasing wing flutter, or the vibrations of the wings due to airflow. Musk famous that a structural battery pack could provide a 10% mass reduction and an chance for a 12% vary increase for its automobiles.
A a short while ago published patent for Tesla’s structural battery pack reveals that the EV maker did not only glimpse at charge reduction and array improvements when it was developing its upcoming-generation batteries. Tesla also seemed at how the structural battery packs could support maintain–if not improve–its vehicles’ security. This was hinted at in the patent’s comprehensive description, which reveals that the bottom layer of the structural battery would be designed from a solid, rigid content that is also capable of deforming in the event of a crash.
Tesla’s structural battery pack patent also outlined how components of the built-in power program are developed to allow gasses to escape from the battery in the party that a cell results in being destroyed. Subsequent is the pertinent area from Tesla’s structural battery pack patent.
“Illustratively, an integrated, unitary battery pack may perhaps be fashioned and used as aspect of the structural support for a car or truck body. For example, the battery pack may include things like a bottom layer that is formed from a honeycomb or ridged surface which is mechanically joined to cells within just the battery pack. The base layer is intended so that it can take in and distribute impact strength from under, mitigating possible harm delicate battery supplies or breach of the sealed battery pack enclosure.
“In 1 embodiment, the base layer is produced from a materials that has enough stiffness and toughness to assistance the battery cells and respond mechanical masses from regular auto procedure, but also can deform in response to a road strike from beneath that would in any other case cause failure in the battery pack procedure. In addition to developing a flexible or crushable composition, the collection of ridges can let gasses to escape from the battery pack ought to destruction happen to a certain mobile, or in the celebration of a thermal runaway transpiring inside of 1 or additional cells of the battery pack.”
Tesla’s vehicles are famed for their outstanding protection ratings. Built with no a large interior combustion motor in front, Tesla’s EVs characteristic generous crumple zones that enable take in the impression in a collision. If the EV maker’s structural batteries seriously make its cars much more structurally seem, then Tesla could further more set up alone as the maker of the safest vehicles on the highway, bar none.
