[0037] The present invention will be further described below in conjunction with embodiment and accompanying drawing.
[0038] see now figure 1 , figure 1 It is a schematic diagram of the lithium-ion battery system of the present invention. As shown in the figure, the lithium-ion battery system 10 includes a power input terminal 12 for connecting to an external voltage source, the charger 14 for controlling the charging of the battery BAT, and a baseband chipset for transmitting and receiving digital Signal. The charger 14 includes a switch CH_SW connected between the VIN pin of the power input terminal 12 and the battery BAT. The charging controller 1402 controls the current through the switch CH_SW according to the signal S1, thereby controlling the charging of the battery BAT. The switch RL_SW is connected to the power supply. Between the D+ pin of the input terminal and the USB detector 1404, the USB detector 1404 detects the level on the D+ pin to generate signals S1 a...
