Embodiment Construction

[0023] A backup battery provided in Embodiment 1 of the present invention such as figure 1 As shown, it includes: a charging module 10 , an input port 11 and an output port 12 . Wherein, the charging module 10 further includes: a detection and display unit 101 , a charging management unit 102 , a boost unit 103 and a battery cell 104 .

[0024] The input port 11 is connected to an external charger, and the battery cell 104 is charged through the charging management unit 102 , and the detection and display unit 101 displays whether the voltage and power of the battery cell 104 of the charging module 10 are fully charged. The output port 12 is used to connect with the external device to be charged. When there is an external power supply, the output voltage of the battery cell 104 is raised to the charging voltage required by the external portable device through the booster unit 103, and the external power supply is used for the charging voltage of the battery cell 104 at the sam...

Abstract

The embodiment of the invention discloses a backup battery, comprising an input unit, a charging module and an output unit; wherein, the charging module comprises a detecting and displaying unit, a charging management unit, an electric core and a voltage increasing unit further. The backup battery of the embodiment of the invention has the advantages of large capacity, being compatible with the charging interfaces of different external chargers and external chargeable equipment, storing electric energy, directly charging external portable equipment, convenient operation, and avoiding the lossof data of a user caused by replacement of battery of equipment.

Description

technical field [0001] The invention relates to electronic circuit technology, in particular to a backup battery. Background technique [0002] At present, many portable devices, such as mobile phones, portable instruments, etc., are powered by batteries, and in many cases, backup batteries are also used. These portable devices often include three main parts, taking a mobile phone as an example, which are: a mobile phone host with a battery, a charger, and one to several spare batteries. [0003] Due to the limitations of appearance and other factors, the spare batteries of these portable devices cannot be interchanged, which has caused the following problems: first, the spare batteries generally have a small capacity, and it is inconvenient to carry multiple or multiple spare batteries; in addition, spare batteries The elimination of the battery will cause the elimination of the portable charging device; finally, in some cases, the replacement of the battery will also caus...
