The embodiment of the invention provides a rechargeable battery lithium separation detection method, a battery management system and a battery system. On one hand, charging voltage and the charge state of a rechargeable battery are detected in the pulse charging process of the rechargeable battery, the charging voltage of the rechargeable battery serves as first voltage, a voltage value corresponding to the charge state is obtained from the corresponding relation between an open-circuit voltage and the charge state to serve as second voltage, and accordingly whether lithium separation happens to the rechargeable battery in the pulse charging process is judged according to the first voltage and the second voltage. Thus, the technical scheme is used for solving the problems that in the prior art, operation is complex when the lithium separation condition of the rechargeable battery is detected, and efficiency for detecting the lithium separation condition is low.
