What is a structural battery pack?

The structural battery pack is a kind of electric vehicle battery that is cleverly designed to efficiently fit into the car. It is part of the vehicle’s chassis, as the battery pack acts as a structural part of the whole car. Seats are directly mounted to the battery pack itself.

What is the practical application of rigid structural batteries?

The practical application of rigid structural batteries relies on addressing two critical core challenges: achieving structural and electrochemical performance that aligns with the multifunctional efficiency design principle (i.e., η s + η d> 1) through advanced materials, technological development, and a rational battery design.

Which electric vehicles use a structural battery pack?

There is only one vehicle that uses a structural battery pack. It is the Texas-made 2022 Tesla Model Y. Giga Berlin will also start producing electric vehicles with structural packs in the coming months. Tesla will improve its existing EVs such as Model 3 and Model S/X with the new pack in the near future.

What are the structural components of electric vehicle battery packs?

In the electric vehicle battery pack described above, the mechanical load-bearing functionality is entirely carried by structural components other than the battery packs. For instance, structural components refer to the module casings and upper and lower battery pack covers.

What are structural batteries?

This type of batteries is commonly referred to as “structural batteries”. Two general methods have been explored to develop structural batteries: (1) integrating batteries with light and strong external reinforcements, and (2) introducing multifunctional materials as battery components to make energy storage devices themselves structurally robust.

Can a rigid structural battery replace the structural components?

Assuming that the rigid structural battery meets the specifications of the structural components, it can replace the remaining 80 % of the structural components. This would effectively increase the available energy of the original system by eightfold.
