Embodiment Construction

[0046] In the embodiment of the present invention, whether to enter the battery storage state is judged by the mode judgment parameter, and in the battery storage mode, the remaining power of the battery is controlled below a certain level, so as to delay the capacity decay of the rechargeable battery of the portable computer.

[0047] The portable computer of the embodiment of the present invention includes a mainboard, a rechargeable battery connected to the mainboard, and a charging circuit for charging the battery, wherein the portable computer also includes a battery management device, such as figure 1 As shown, the battery management device includes:

[0048] a discharge circuit for discharging the battery;

[0049] An acquisition module, configured to acquire mode judgment parameters;

[0050] The first judgment module is used to judge whether to enter the battery storage mode according to the mode judgment parameter;

[0051] The first control module is used to contr...

Abstract

The present invention provides a battery management device and a portable computer, the battery management device is for managing the rechargeable battery provided in a portable computer, the portable computer is provided with a charge circuit for charging a battery, the battery management device comprises: a discharge circuit for discharge the battery; a acquiring module for acquire the mode determining parameter; a first determining module for judging whether the battery storage mode is entered according to the mode determining parameter; a first control module for controlling the charge circuit or the discharge circuit to control the amount of electrical charge of the battery so that the amount of electrical charge of the battery is lower than the second amount of electrical charge threshold in the battery storage mode; the performance of the battery when deposited with the amount of electrical charge lower than the second amount of electrical charge threshold is better than the performance when deposited with the amount of electrical charge higher than the second amount of electrical charge threshold. The present invention alleviates the attenuation of the amount of electrical charge capacity of the rechargeable battery of the portable computer.

Description

technical field [0001] The invention relates to the management of rechargeable batteries, in particular to a battery management device and a portable computer. Background technique [0002] As the performance of the portable computer is getting better and better, more and more home users have already regarded it as a must-have electronic product in the family. [0003] For portable computers, all are equipped with rechargeable batteries, so that portable computers can be used for a period of time when there is no external power supply. [0004] However, compared with business users, many home users are in a fixed place in most cases, and an external power supply provides power support for the portable computer. [0005] For existing portable computers, when it is powered by an external power supply, the battery will be taken out and stored, but in this way, the part covered by the battery will be exposed in the portable computer, and foreign objects (such as dust, etc.) wil...
