CELLS CONTACT SHEETS, CELLS CONTACT SYSTEMS, AND BATTERY PACKS

A cells contact sheet (011), a cells contact system (001) and a battery pack are disclosed. The cells contact sheet (011) is applicable to a battery module including cell groups and includes cells contact sub-sheets (111) and at least one connecting sheet (112). The cells contact sub-sheets (111) are configured to acquire work signals of the cell groups, respectively. The connecting sheet (112) is arranged between every two adjacent ones of the cells contact sub-sheets (111), and two ends of the connecting sheet (112) are respectively connected with the two adjacent ones of the cells contact sub-sheets (111). The connecting sheet (112) is provided with a first bending structure (1121) configured to deform when two of the cell groups corresponding to the every two adjacent ones of the cells contact sub-sheets (111) move away from each other or close to each other.
