Abstract

The invention relates to a power supply device and a power supply method. The power supply device comprises a main battery module, a second battery module and a voltage converting module. A computer system is supplied with power by the main battery module or the second battery module. When the main battery module and the second battery module switch power supply, the power is supplied for the computer system by the voltage converting module till the switching is finished.

Description

technical field [0001] The present invention relates to a power supply device, and in particular to a power supply device for a computer system. Background technique [0002] General notebook computers and various portable electronic computer devices mostly use batteries as the main source of power supply to meet the requirements of portable features. Due to the limitation of the size of the battery, most of them have a certain limited power supply time. For users who operate this type of equipment for a long time, the limited power supply time limits the degree of freedom of the user's operation. Therefore, prolonging the power supply time is a very important issue for portable products. [0003] In order to prolong the power supply time, the power storage capacity of the battery of the computer equipment is generally increased. The Ni-MH batteries and lithium batteries currently used in notebook computers can only maintain a power supply for several hours. However, limi...
