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.
BYD's blade battery is revolutionary in several ways. We are happy to explain why this is the case, as well as the importance of the so-called Nail Penetration Test. One of the most important parts of an electric vehicle is the battery system. After years of study, research and development, BYD has come up with the Blade Battery.
The Blade Battery has undergone the most rigorous safety testing and exceeds the requirements of the Nail Penetration Test, the most rigorous way to test battery thermal runaway. This test simulates the consequences of a serious traffic accident and is considered 'The Mount Everest' among battery tests.
Efficiency and extended range are other benefits of the Blade Battery, offering greater power density for optimal performance and efficiency, including faster charging. BYD CTP (Cell to Pack) technology makes the difference, with the Blade Battery increasing space utilization by 50%.
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).
The accompanying exploded view of the Blade battery shows its simplicity. Typical dimensions of the compact, single-cell design are 905 x 118 x 13.5 mm (35.6 x 4.6 x .53 in.). The size can be customized. The thin, blade-like cells are inserted into the pack in a blade-type array.
