Provided is a domain control-based battery management system, comprising a domain controller (01), a power battery pack (02) and a daisy chain wire harness; the power battery pack (02) is provided with battery cells (021), acquisition plates (022) used for acquiring first battery parameters of the battery cells (021), and a high-voltage plate (023) used for acquiring second battery parameters of the power battery pack (02); the daisy chain wire harness comprises a first daisy chain (031) and a daisy chain branch (032); the first daisy chain (031) is connected between the domain controller (01) and the acquisition plates (022); and one end of the daisy chain branch (032) is connected to the high-voltage plate (023), and the other end of the daisy chain branch (032) is connected to the domain controller (01) by means of the first daisy chain (031). Said system can improve the safety of battery management and reduce the production cost of the power battery pack.
