A cell state acquisition apparatus and a power battery using the cell state acquisition apparatus. A cell state acquisition apparatus having an acquisition board assembly, a first interface fixed at the bottom surface of a cell, a second interface fixed at the top end of another cell and a connecting seat connecting the first interface and the second interface; the acquisition board assembly including a PCB board, a signal processing module and a communication module mounted on the PCB board and a fixed block which is matched to be inserted in the first interface; and a signal acquisition module which is used for acquiring a cell state signal corresponding to the second interface is mounted on the fixed block. The signal acquisition module is integrated with the signal processing module and the communication module via the acquisition board assembly, and the connecting seat, the first interface and the second interface are provided to mount the acquisition board assembly between the cells which are connected in series, so that the use of a connection conductive line is reduced and shortened, and a layout space is saved, thus facilitating the heat dissipation of a cell.
