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.
There are generally two manufacturing processes for batteries: winding and stacking processes. The blade battery adopts advanced high-speed stacking process, the length of the stacking pole piece can reach about 1000mm, the stacking alignment tolerance is within ±0.3mm, and the single stacking efficiency is 0.3s/pcs.
Arranged in an array in one pack, each cell serves as a structural beam to help withstand the force. The aluminum honeycomb-like structure, with high-strength panels on upper and lower side of the pack, greatly enhances the rigidity in vertical direction. It is this revolutionary design that gives optimised strength to 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.
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 Blade Battery – Unsheathed to Safeguard the World”, Wang Chuanfu, BYD Chairman and President, said that the Blade Battery reflects BYD’s determination to resolve issues in battery safety while also redefining safety standards for the entire industry. BYD are able to make cells to a range of dimensions.
