Abstract: A method, an apparatus and a system for controlling charging of a battery module are provided in the present disclosure. The method for controlling charging of the battery module may include: acquiring an internal pressure value of the battery module; determining a target pressure threshold range to which the acquired internal pressure value of the battery module belongs, based on a plurality of predefined pressure threshold ranges; obtaining a target charge cutoff voltage corresponding to the target pressure threshold range, based on a correspondence relationship between a plurality of predefined charge cutoff voltage and the plurality of predefined pressure threshold ranges; and controlling the battery module to be charged based on the obtained target charge cutoff voltage.
