The invention relates to a battery, particularly provides a signal sampling device, a battery management system and a battery pack, and aims to solve the problem of high cost of a sampling device in an existing battery pack. In order to achieve the purpose, the signal sampling device comprises a first plate, a second plate and a sampling terminal, the first plate is provided with a sampling chip electrically connected with the first plate, and the second plate is electrically connected with the first plate through a transmission line; the first end of the sampling terminal is electrically connected with the battery core, and the second end is electrically connected with the first plate or the second plate; wherein the state information of the battery cell is transmitted to the sampling chip through the sampling terminal, the second plate and the first plate, or is transmitted to the sampling chip through the sampling terminal and the first plate. The circuit board is divided into the first board and the second board, so that the length of a single circuit board can be effectively reduced. Therefore, the state information of the battery cell connected with the second plate can be transmitted to the first plate through the transmission line, so that the efficiency of the sampling chips is exerted to the maximum, the use number of the sampling chips is reduced, and the cost is saved.

    本发明涉及电池,具体提供一种信号采样装置、电池管理系统及电池包,旨在解决现有电池组中采样装置成本较高的问题。为此目的,本发明的信号采样装置包括第一板、第二板和采样端子,第一板上设置与其电连接的采样芯片,第二板通过传输线路电连接第一板;采样端子的第一端与电芯电连接,第二端与第一板或第二板电连接;其中,电芯的状态信息通过采样端子、第二板和第一板传输至采样芯片,或,通过采样端子和第一板传输至采样芯片。通过将电路板分为第一板和第二板,能够有效地降低单块电路板的长度。第二板所连接的电芯的状态信息能够经传输线路传输至第一板,从而使采样芯片的效率发挥至最大,进而降低采样芯片的使用数量,以节省成本。
