1. A charging management system for receiving a signal from a battery to be charged, and controlling a charging circuit of a charger so as to charge the battery according to the received signal, the charging management system comprising:

  • a first signal-output port adapted for outputting a first control signal representing a first charging current to the charging circuit;

    a second signal-output port adapted for outputting a second control signal representing a second charging current to the charging circuit;

    a third signal-output port adapted for outputting a third control signal representing a variable third charging current to the charging circuit; and

    a controller electrically connected with the first, second and third signal-output ports so as to control the charging management system to operate in at least one of a first mode and a second mode, wherein(i) in the first mode, the controller selectively controls outputs of the first signal-output port and the second signal-output port; and
