Charging management system and charger with the same
First Claim
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
(ii) in the second mode, the controller only controls an output of the third signal-output port.

Abstract
The present invention discloses a charging management system and a charger with such charging management system. The charging management system includes a first signal-output port, a second signal-output port, a third signal-output port and a controller electrically connected with the first, second and third signal-output ports. The first and second signal-output ports are adapted for outputting first and second control signals representing first and second charging currents, respectively, to a charging circuit. The third signal-output port is adapted for outputting a third control signal representing a variable third charging current to the charging circuit. The controller controls the charging management system to operate under at least one of two modes. In the first mode, the controller alternately controls the first and second signal-output ports to output the first and second control signals. In the second mode, the controller only controls the third signal-output port to output the third control signal.
