With CTP technology, battery packs are assembled directly from the cells without the need for modules. Many battery manufacturers, such as BYD Auto, CATL, LG Chem, and SVOLT, are exploring CTP technology. The Blade Battery is BYD’s realization of the CTP concept (Figure 1). Figure 1. The structure of the Blade Battery from cell to pack.
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.
BYD’s Blade Battery design explored a bold CTP concept through its module-free pack. High quality control in materials and cell manufacturing, however, remain critical prerequisites of CTP. Xinghua Meng is a battery research scientist in the United States.
