FAQS about Blade battery energy storage system composition diagram

What is a blade battery?

The structure of the Blade Battery from cell to pack. At the center of the design of the Blade Battery is the cell geometry, which has a much lower aspect ratio compared with conventional cylindrical or prismatic cells. According to BYD’s patents, the cell depth (Z axis) is 13.5 mm while the cell length (X axis) can range from 600 mm to 2500 mm.

Why did BYD create a blade battery?

Believing this an impractical path, BYD puts the spotlight back on safety and stability in presenting the Blade Battery. In pushing toward a safer electric vehicle battery design, BYD realized that it needed to package LiFePO4's inherent stability and safety advantages into a battery pack with energy capabilities comparable to lithium-ion.

What is a module-free blade battery?

The module-free Blade Battery, however, takes advantage of its blade cells to increase the volumetric energy density by up to 50%, suggesting a potential VCTPR and GCTPR of 62.4% and 84.5%, respectively. Although the Blade Battery shows a lot of promise, the blade geometry is not perfect .

What makes BYD a module-free battery pack?

This story is contributed by Xinghua Meng and Eric Y. Zheng With cell-to-pack technology, BYD designed the module-free battery pack using the Blade Cell. The geometry of the Blade Cell is a key to the realization of the module-free battery pack. With the module-free pack design, VCTPR and GCTPR can be enhanced to over 60% and 80%.

Does a module-free blade battery increase volumetric energy density?

Even worse, this low volumetric energy density often requires car designers to make room for a larger pack. The module-free Blade Battery, however, takes advantage of its blade cells to increase the volumetric energy density by up to 50%, suggesting a potential VCTPR and GCTPR of 62.4% and 84.5%, respectively.

What is the difference between a module and a blade battery?

The height of the Blade Battery is reduced by ~50 mm, compared with regular LFP battery back with modules, providing more space to the passengers and decreasing the coefficient of drag (0.233 cd for BYD Han). In the Z direction, the structure of the Blade Battery is completely different from conventional module-based battery packs (Figure 3).
