Brief description of the drawings
In order to illustrate more clearly of the utility model embodiment technical scheme, below will be to make needed for embodiment description Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are some embodiments of the present utility model, for For those of ordinary skill in the art, on the premise of not paying creative work, other can also be obtained according to these accompanying drawings Accompanying drawing.
Fig. 1 is a kind of schematic diagram of novel battery bag with communication function that the utility model embodiment is provided;
Fig. 2 is the voltage change figure of the charger detection in communication process of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is a part of embodiment of the utility model, rather than whole implementation Example.Based on the embodiment in the utility model, those of ordinary skill in the art are obtained under the premise of creative work is not made The every other embodiment for obtaining, belongs to the scope of the utility model protection.
Such as Fig. 1, a kind of novel battery bag with communication function of the utility model embodiment, including sampling module, MCU moulds Block, metal-oxide-semiconductor Q1 and battery pack B, the first voltage test side of sampling module are connected with the positive pole of battery pack B, sampling module Second voltage test side is connected with the negative pole of battery pack B, the signal output part of sampling module and the signal detection end phase of MCU module Even, the first control end of MCU module is connected with the grid G of metal-oxide-semiconductor Q1, and the drain D of metal-oxide-semiconductor Q1 is connected with the negative pole of battery pack B, The source S of metal-oxide-semiconductor Q1 is connected with the negative output terminal J2 of charger, and the positive pole of battery pack B is connected with the positive output end J1 of charger.
Wherein, by the detection of the first voltage test side and second voltage test side of sampling module, battery can be obtained The real-time voltage of group B, and the magnitude of voltage is transferred to the signal detection end of MCU module by the signal output of sampling module, If the voltage that MCU module detects now exceedes default over-pressed voltage, the first control end of MCU module then controls metal-oxide-semiconductor Q1 disconnects, so as to carry out the charge protection of electric voltage over press, it is to avoid the damage that battery pack is overcharged and caused.
Wherein, a diode in parallel between the drain electrode of metal-oxide-semiconductor Q1 and source electrode.Between the drain electrode of metal-oxide-semiconductor Q2 and source electrode A diode in parallel.
Therefore, the specific operation principle of whole circuit is as follows, and when battery bag charges normal work, metal-oxide-semiconductor Q1 leads Logical, now the negative pole of battery pack B is conducted with the negative output terminal J2 of charger, now the voltage on the positive output end J2 of charger It is pulled low, i.e. the voltage of the positive output end of charger and the voltage of battery pack is equal.
And when MCU module judges that battery pack B is overcharged according to the voltage received from sampling module, i.e. the voltage of battery pack During for over-pressed voltage, MCU modules can control metal-oxide-semiconductor Q1 to turn off, and now the voltage of the positive output end of charger is returned to and filled The open-circuit voltage of electrical equipment.So when can according to battery pack charge normal with after charge protection, the electricity of the positive output end of charger Buckling so that charger obtains battery pack and carried out the signal of charge protection.
Specifically, as shown in Fig. 2 after metal-oxide-semiconductor Q2 disconnects, now the positive output end output of charger is charger Open-circuit voltage V2, controls metal-oxide-semiconductor Q1 to turn on Preset Time by MCU module, and now the positive output end output of charger is electricity The over-pressed voltage V1 of pond group B, then controls metal-oxide-semiconductor Q1 to disconnect Preset Time again, and back and forth(Reciprocal number of times can basis Actual conditions set, you being 2 times, or 3 times, or 4 times or 5 times), in this process, charger The voltage change figure that positive output end is detected is regular change, if the positive output end of charger is detected as shown in Figure 2 Regular voltage change figure, then show that now battery pack B has been overcharged, and realizes the communication between battery pack B and charger, Now charger then stops its output of charging, it is possible to lights the prompting that related indicator lamp is overcharged, further protects The safety of whole battery bag.
Used as preferred, the novel battery bag also includes the thermistor R2 of a temperature for being used to detecting battery pack B, heat One end of quick resistance R2 is connected with the temperature detection end of sampling module, the other end of thermistor R2 and the negative pole phase of battery pack B Even.
Wherein, when battery pack is overheated, MCU module can also be according to the temperature detection end of sampling module and temperature-sensitive The current versus cell group B that resistance R1 cooperatings are detected carries out temperature protection, i.e., when the temperature of battery pack B is too high, temperature-sensitive The magnitude of voltage of resistance R1 can occur corresponding change, and sampling module sends thermistor R1 variable signals to MCU module so that The conducting and disconnection of MCU module control metal-oxide-semiconductor Q1, to improve the security performance of battery bag.
In addition, as it is further preferred that the novel battery bag also includes an a resistance R3 and metal-oxide-semiconductor Q2, sampling The one end of the first current detecting end, the source S of metal-oxide-semiconductor Q2 of module with resistance R3 is connected, the second electric current inspection of sampling module Survey the other end with resistance R3 of end, the negative pole of battery pack B to be connected, the second control end of MCU module and the grid G of metal-oxide-semiconductor Q2 It is connected, the drain D of metal-oxide-semiconductor Q2 is connected with the drain D of metal-oxide-semiconductor Q1.
Wherein, the first current detecting end of sampling module cooperates with the second current detecting end, to measure by resistance The electric current of R2 is simultaneously sent to MCU module, if in discharge process, MCU module is detected to be exceeded by the electric current of resistance R2 and preset Overcurrent, then now then the second control end of sampling module then controls metal-oxide-semiconductor Q2 to turn off, so as to further protect Whole battery bag is protected, the security performance of battery bag is further increased.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to In this, any one skilled in the art can readily occur in various in the technical scope that the utility model is disclosed Equivalent modification or replacement, these modifications or replacement should all be covered within protection domain of the present utility model.Therefore, this practicality New protection domain should be defined by scope of the claims.
