Detailed description of the invention
Lithium battery protection circuit of the present utility model, it is adaptable to the lithium battery of protection solar LED integrated lamp.Specifically, as it is shown in figure 1, solar LED integrated lamp includes processing module 10, lithium battery 11, the front-end circuit 12 of processing module 10 and lithium battery protection circuit 13.
Specifically, such as Fig. 1, front-end circuit 12 is connected between processing module 10 and lithium battery 11, and is connected with processing module 10 and lithium battery protection circuit 13.
Being also known that by Fig. 1, the protection circuit 13 of lithium battery specifically includes calandria 130 and temperature inductor 131.
Wherein, temperature inductor 131 is connected with lithium battery 11 and processing module 10, for sensing the temperature value of lithium battery 11.Calandria 130 is connected with lithium battery 11 and front-end circuit 12, for detecting that in processing module 10 temperature value of lithium battery 11 that temperature inductor 131 sense heats lithium battery 11 when being reduced to affect its discharge performance.
Specifically, in one embodiment, processing module 10 includes that single-chip microcomputer, front-end circuit 12 include audion and paster socket 4P.Processing module 10, when temperature value lithium battery 11 that temperature inductor 131 senses being detected is reduced to affect its discharge performance, controls the audion in its front-end circuit 12 and paster socket 4P conducting so that calandria 130 begins to warm up lithium battery 11.
It is to be appreciated that when processing module 10 is when temperature value lithium battery 11 that temperature inductor 131 senses being detected is too high, controls the audion in its front-end circuit 12 and paster socket 4P be not turned on so that calandria 130 stops heating lithium battery.
Wherein in an embodiment, calandria 130 includes that PCB temperature control plate 132, temperature inductor 131 include thermal resistance, and temperature inductor 131 is arranged on the second surface of PCB temperature control plate 132.The most specifically combine Fig. 2 and Fig. 3 the lithium battery protection circuit 13 of the present embodiment is described in detail.
As in figure 2 it is shown, be the first surface schematic layout pattern of PCB temperature control plate.As shown in Figure 2, the first surface (being assumed to the bottom of PCB temperature control plate in the present embodiment) of PCB temperature control plate 132 is provided with equally distributed Copper Foil wire 133.And pad 134 that the first surface of PCB temperature control plate 132 is provided with temperature inductor 131 and the solder joint 135 being connected with the negative or positive electrode of lithium battery 11.As it is shown on figure 3, the second surface of PCB temperature control plate 132 is provided with temperature inductor 131 and security unit 134.
Wherein, temperature inductor 131 includes that thermal resistance, security unit 134 include fusing resistor.Security unit 134 is connected with Copper Foil wire 133.And in the present embodiment, the paster socket 4P in front-end circuit 12 is arranged on the second surface of PCB temperature control plate 132, from the figure 3, it may be seen that thermal resistance and paster socket 4P and fusing resistor are serially connected.And fusing resistor is when processing module 10 is out of control, prevent the electric current flowing through Copper Foil wire 133 from making PCB temperature control plate 132 be chronically to add and hanker.
Paster socket 4P is in the present embodiment, including 4 contacts, wherein the first contact ground (not shown), the second contact is connected with one end of thermal resistance, 3rd contact is connected with fusing resistor, and the 4th contact is connected to the audion (not shown) in front-end circuit 12.
Specifically, in the present embodiment, the resistance of thermal resistance can change along with the temperature value of lithium battery 11, processing module 10 monitors the resistance of thermal resistance in real time, and judges the Current Temperatures of lithium battery 11 according to the change in resistance of thermal resistance, when processing module 10 is judged that the temperature value of lithium battery 11 is too low and affected its discharge performance, output controls voltage signal and front-end circuit 12 is turned on, namely have electric current to flow through PCB temperature control plate 132, now, Copper Foil wire 133 begins to warm up lithium battery 11.
Further, when the temperature value of lithium battery 11 is too high, processing module 10 detects that the resistance correspondence of thermal resistance changes to corresponding resistance, then control front-end circuit and close.Namely do not have electric current to flow through PCB temperature control plate 132, now, Copper Foil wire 133 stops heating lithium battery 11.
In the preferred version of the present embodiment, when processing module 10 is out of control, in order to prevent electric current from not arrheaing PCB temperature control plate 132 so that Copper Foil wire 133 does not stop heating, has sealed in fusing resistor between Copper Foil wire 133 and front-end circuit 12.Fusing electricity rents the function that device has both resistance and electric fuse, when processing module 10 normally works, only uses as resistor.When processing module 10 is out of control, if the electric current flowing through fusing electricity rent device is excessive, then it fuses automatically, protects whole circuit safety.
Specifically, in the present embodiment, fusing resistor is paster fuse-resistor fuselage, when circuit malfunctions, stream occurred time, the temperature of fusing resistor will be increased to 500 DEG C～600 DEG C in a short period of time.At this moment resistive layer is just fused by thermal spalling, plays the effect of insurance, reaches the purpose of safety.
It is to be appreciated that the change in resistance that processing module 10 is by thermal resistance, also can determine whether out the electricity of lithium battery 11 in circuit, when the electricity of lithium battery 11 is the lowest, processing module 10 also controls to flow through the electric current of Copper Foil wire 133, stops heating.
In the scheme that the present embodiment is further preferred, lithium battery protection circuit 13 also includes insulation film (insulation film not shown in figure).Specifically, insulation film includes insulating rubber plastic, and calandria 130, temperature inductor 131 and lithium battery 11 is all wrapped in insulation film.When the ideal temperature value that temperature value is its discharge and recharge of lithium battery 11, stop lithium battery 11 is heated, and wrap up lithium battery 11 by insulation film so that lithium battery 11 works the longer time under preferable temperature value, be conducive to extending the service life of lithium battery.
Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, all it is considered to be the scope that this specification is recorded.
Embodiment described above only have expressed several embodiments of the present utility model, and it describes more concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
