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.
