Solar Panel And Bulletproof Armor Glass in new Tesla's Patent Application
May 28, 2021 Solar Panel And Bulletproof Armor Glass in new Tesla's Patent Application

Tesla revealed its plan in a new patent application for a folding solar bed cover for its Cybertruck electric pickup truck.

Cybertruck is designed to have the utility of a truck with sports car performance. Built to be durable, versatile, capable, and high-performance.

 Elon Musk and his team have their views aimed at the American pickup truck market with the all-new electric Cybertruck. Tesla’s CEO,  Elon Musk after lunching Cybertruck surprised many when he said that Tesla’s new electric pickup will have a solar roof opportunity that offers a range of 15 miles per day.

This announcement was surprising since several automakers, even Tesla itself,  had already explored adding solar power to electric vehicles, but most projects didn’t go into production or provide any meaningful amount of electricity.

Elon Musk stated In 2017 that he pushed Tesla engineers to look into incorporating solar cells into Model 3, but they determined it wasn’t worth it at the time.

Solar cell efficiency has advanced since then, and Tesla has developed its own know-how for inserting solar cells throughout the development of solar roof tiles.

As more space is available for flat panels, Cybertruck could be considered as a potential concept for integrating with the solar panel. This is not possible with traditional electric cars, as that much flat surface is not available.


Tesla’s design for the retractable duvet with embedded solar cells has now been revealed in a patent application (Integrated Tonneau cover for a vehicle). Tesla describes the system in the patent application:

A truck bed cover (e.g., truck) is integrated into a vehicle configured to move through an opening between a cab and truck bed and along a series of channels on the truck bed. The vehicle includes a motor that engages the truck bed cover and is configured to enable the truck bed cover's automated movement along with the channel set. The vehicle in one embodiment is an electric vehicle configured to run from a battery pack stored in the electric vehicle. The truck bed cover contains multiple moving parts, with multiple moving parts interconnected in a flexible format.

 Tesla published some drawings in the patent application illustrating how the cover turn over into the truck. This is impressive when you consider that it is apparently strong enough to stand on the cover.


Cybertrunck’s bulletproof armor glass

As the patent submitted said, “Integrated Tonneau Cover for a Vehicle”. The Cybertruck’s stainless steel is strong enough to tolerate several blows of sledgehammer without cracking.

However, the glass armor for the payload is something pickup trucks don’t get and was much needed. In 2019 when Cybertruck’s strength was exhibited, Elon Musk proved that the glass material of Cybertruck was strong too. As this patent was applied, it became clear how the Cybertruk glassworks.

The bulletproof glass is a multi-layer glass load, which the inner layer chemically strengthened high strength in flexibility. And the inner layer measures about 0.5 to 1.1 millimeters thick. This grass has energy absorptive properties, with an adhesive interlayer attaching itself to the outer layer, the strength sticks together. Furthermore, the outer layer is made of highly densified, low-CTE, non-soda lime glass. And measures about 2 thick. The further outer layer is about 5 millimeters thick made of boric oxide and silica. Additionally, it is also resistant to thermal shock.

However, glass armor is not the only advantage. It does occupy space and limits the load space. But, as the cover can be used as a solar panel, the added feature may be added benefit.

With the solar panels absorbed on the Tesla Cybertruck’s top, 110 solar electric cells are connected to the battery. As the solar patent states, “When the tonneau cover is deployed to cover the bed. And the solar electric cells that make up the slats are facing the sun, the battery within the electric vehicle can be charged by solar electric cells.”
