With cell-to-pack technology, BYD designed the module-free battery pack using the Blade Cell. 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.
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 .
“ Battery module means a set of battery cells that are connected together or encapsulated within an outer casing to protect the cells against external impact, and which is meant to be used either stand-alone or in combination with other modules” [ 16] (p. 64).
Why module-free？ The conventional battery manufacturing process is from cell to module, and then from module to pack. This intermediate step divides the battery into separate modules, each of which can have its own independent battery management and diagnostic systems.
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).
Approach: “ Cell-to-Pack ” describes a new type of structure of battery systems, which is characterized by the direct integration of the battery cells into the battery pack [ 13 ]. This allows for the reduction in the passive/non-energy storing components of the battery module.
