Description
Technical field
This utility model is related to power supply, particularly to a kind of power-supply system.
Background technology
On existing market, similar stand-by power supply, mostly relatively simple in design, using 2 or 4 18650 cylindrical batteries
(also useful polymer battery), plus the common protection board of lastblock and lifting die block, realize charging under civil power for the battery and
Itself charge function to external equipment, is used to make the stand-by power supply of most of electronic equipments.These stand-by power supply function lists
One, put when filling and battery can be caused short, there is certain potential safety hazard.
Utility model content
The technical problems to be solved in the utility model is：A kind of power-supply system is provided, improves stand-by power supply in power-supply system
Battery life, reduce potential safety hazard.
For solving the above problems, the technical solution adopted in the utility model is：A kind of power-supply system, including main power source and standby
With power supply, described stand-by power supply includes battery, voltage-stabilizing output circuit, DC-DC circuit and automatic switch-over circuit；Wherein：Automatically cut
Change circuit to be connected with DC-DC circuit, the first temperature protection circuit, voltage-stabilizing output circuit, battery and the first temperature protection circuit are even
Connect.
Further, also include second temperature protection circuit, second temperature protection circuit is connected to battery and voltage stabilizing output electricity
Between road.
Further, described battery is further connected with battery protection module.
The beneficial effects of the utility model are：Stand-by power supply of the present utility model passes through to increase automatic switch-over circuit, permissible
Directly civil power is changed without through battery, so can extend the service life of power supply, protection board be entered simultaneously
Row improves, and increased the first temperature protection circuit, can automatically cut off electricity when stand-by power supply temperature anomaly in charge and discharge process
Source, protection battery be not in temperature too high and the problems such as lead to equipment spontaneous combustion to damage, improve security performance.
Brief description
Fig. 1 is the structured flowchart of embodiment；
Specific embodiment
As shown in figure 1, embodiment includes battery, DC-DC circuit, voltage-stabilizing output circuit, automatic switch-over circuit, the first temperature
Protection circuit and second temperature protection circuit, wherein：Automatic switch-over circuit and DC-DC circuit, the first temperature protection circuit, second
Temperature protection circuit connects, and battery is connected with the first temperature protection circuit, and voltage-stabilizing output circuit is with second temperature protection circuit even
Connect.
Above-mentioned, the first temperature protection circuit, it is used for realizing, in stand-by power supply charge and discharge process, automatically cutting off during temperature anomaly
Power supply；Second temperature protection circuit, during directly externally exporting power supply for automatic switch-over circuit, automatic during temperature anomaly
Cut off the electricity supply.DC-DC circuit is connected with external adapter, is also required to electricity when there being civil power from adapter input and outside stand-by power supply
During the output of source, automatic switch-over circuit can disconnect the circuit of battery, and stand-by power supply directly passes through automatic switch-over circuit and voltage stabilizing output
Circuit externally exports；When having civil power when adapter inputs and its exterior does not need power supply output, stand-by power supply passes through automatically
Switching circuit is charged to battery；When no civil power is when adapter inputs and stand-by power supply outside need power supply exports, standby
Power supply directly passes through battery and automatic switch-over circuit externally exports.
For avoiding the abnormal impact to battery of battery voltage, electric current etc. in charge and discharge process, battery is further connected with battery and protects
Shield module.
It should be noted that above DC-DC circuit, voltage-stabilizing output circuit, automatic switch-over circuit, the first temperature protection electricity
Road, second temperature protection circuit and battery protection module are the physical hardware of routine, and this area can according to practical situation certainly
By selecting, this utility model is not specifically limited.
The foregoing describe ultimate principle of the present utility model and main feature, the description of description simply illustrates this practicality
New principle, on the premise of without departing from this utility model spirit and scope, this utility model also has various change and changes
Enter, these changes and improvements both fall within the range of claimed this utility model.
