Embodiment Construction

[0028] Please refer to figure 1 , figure 1 It is a schematic diagram of a portable computer system 10 according to an embodiment of the present invention. The portable computer system 10 can be a notebook computer, a personal digital assistant, etc., and includes a host 100 and a power supply device 102 . The power supply device 102 is used to provide power to the host 100 to perform correlation calculations. The power supply device 102 includes a power storage device group 104 , a charging device 106 and a control device 108 . The power storage device group 104 includes power storage devices B_1˜B_n for storing power and outputting a discharge current i from a power storage device B_x DIS to the host 100 to drive the operation of the host 100. The charging device 106 is used to receive a power supply PWR and generate a corresponding charging current i CH , to charge another power storage device B_y. In other words, in the power storage device group 104, the discharge cu...

Abstract

The invention relates to a power supply management method and a power supply device of a portable computer and a computer system, in particular to a power supply management method for a portable computer system. The portable computer system comprises multiple power storage devices which are used for storing a power supply and outputting discharge current to the portable computer system. The powersupply management method comprises the following steps of: receiving the power supply, and generating corresponding charge current so as to charge one power storage device of the multiple power storage devices; and comparing the discharge current and the charge current so as to regulate the power consumption of the portable computer system. The invention can improve the power supplying mode of a multi-battery system so that a user can normally use the functions of the portable computer system during charge and properly regulate the power consumption of the portable computer system so that thespeed of the charge and discharge is same or the speed of the discharge is reduced, thereby prolonging the service time.

Description

technical field [0001] The present invention relates to a power management method for a portable computer system and its related power supply device and portable computer system, in particular to a power management method capable of prolonging the use time, its related power supply device and the portable computer system. Background technique [0002] Portable computer systems, such as notebook computers, personal digital assistants, etc., have the characteristics of small size, light weight, and portability, which allow users to easily work outside the office and use various functions of the computer system. No longer have to be confined to your desktop by a bulky desktop computer. [0003] Generally speaking, a portable computer system includes a rechargeable battery to provide the power required for its operation, thereby achieving the purpose of portable operation. Due to the limited power that the rechargeable battery can store, when the power of the rechargeable batte...
