    Hello,

    Battery_status message can give the SOC of the sink.
    The info will be available only on the PD3 sink( designed with version> = PD3.0 v1.2).

    PD2 devices do not have similar communication.
    That information is handled in the dpm_user part and needs to be updated by the user/ customer.

    Best regards
