Embodiment Construction

[0030] The spirit of the charging device that can dynamically adjust the charging power proposed by the present invention is that when the output power of the external power supply is fixed, the charging power of the charging device can be dynamically adjusted according to the working power of the notebook computer, so that the output power of the external power supply can be utilized more efficiently. At the same time, the charging time of the rechargeable battery can also be shortened and the charging efficiency can be improved.

[0031] Please refer to Figure 5 , which shows a circuit block diagram of a system device 500 capable of dynamically adjusting charging power proposed by the present invention. The system device 500 of the present invention is coupled to an external power source 502 . It includes the charging device 503 and the main function device 504 of the present invention. The charging device 503 of the present invention is used for charging the rechargeabl...
