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.
In the future, it is necessary to highlight the advantages of the blade battery and put it into application. This paper integrates current information about BYD blade battery and compares the cars using the blade battery with the cars using other power batteries, so as to play a role in the promotion of BYD blade battery in the future.
The Blade Battery uses Lithium Iron Phosphate (LFP) which has undergone standard testing through the Nail penetration test method. In this test a nail is driven through the center of the battery cell until it penetrates to the other side causing a short circuit inside the battery cell.
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).
This was because BYD had successfully developed a new type of battery called the Blade Battery, which uses Lithium Iron Phosphate (LFP) and has passed the standard Nail penetration test. In this test, a nail is driven through the center of the battery cell until it penetrates to the other side, causing a short circuit inside the battery cell.
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.
