A battery pack is a set of batteries or battery cells arranged in series or parallel to supply power. It stores energy for devices like electric vehicles. Battery packs can be primary (non-rechargeable) or secondary (rechargeable) and usually use lithium-ion cells. Proper packaging, sealing, and assembly are essential for performance.
This article provides a brief introduction and comparison of the current mainstream battery pack structures: CTP (Cell To Pack), CTC (Cell To Chassis), CTB (Cell To Body), and CTM (Cell To Module). CTP stands for Cell To Pack, meaning that the cells are directly assembled into the battery pack.
The first-generation battery pack design was called CTM (Cell to Module). The meaning is that a certain number of battery cells are integrated into independent small battery modules, and then several modules are packaged into battery packs through physical partitions.
Technical terms associated with battery packs include “capacity,” which refers to the total amount of energy a battery can store, usually measured in ampere-hours (Ah), and “voltage,” the electric potential difference measured in volts (V).
A lithium-ion battery pack is a collection of multiple lithium-ion cells connected together to store and provide electrical energy. These battery packs power various electronic devices, from smartphones to electric vehicles, due to their high energy density and rechargeable nature.
In this structure, the cells are connected to form the entire battery pack, eliminating the traditional module assembly process. This approach improves space utilization, reduces the size and weight of the battery pack, making it more compact and reducing energy loss between cells.
