The mobile phone lithium ion battery mainly is made up of electric core, safety control circuit and three parts of encapsulation.Wherein the most important thing is electric core segment, form, when battery is charged by electrode, electrolyte, barrier film and shell; Have lithium ion to take place on the positive pole of battery, the lithium ion of generation arrives negative pole through electrolyte movement, and the carbon of negative pole is layer structure; A lot of micropores are arranged; The lithium ion that arrives negative pole will be embedded in the micropore, and the lithium ion of embedding is many more, and charging capacity is high more.Same reason when battery is discharged, is embedded in lithium ion in the negative pole carbon-coating and moves back anodally, and it is many more to get back to anodal lithium ion, and discharge capacity is high more.
Because the chemical characteristic of lithium ion battery; In normal use, the chemical positive reaction that electric energy and chemical energy transform is each other carried out in its inside, but under certain conditions; Will cause inside battery generation chemical side reactions as it being overcharged, crossing to put; Might puncture the barrier film in the battery battery core, make the both positive and negative polarity in the electric core produce short circuit, cause HTHP to produce blast.
Summary of the invention
For this reason, the purpose of the utility model is to provide a kind of system for detecting temperature that prevents the battery of mobile phone blast, causes the problem of blast to solve the Yin Wendu rising in use of present battery of mobile phone.
For realizing above-mentioned purpose, the utility model mainly adopts following technical scheme:
A kind of system for detecting temperature that prevents the battery of mobile phone blast; Comprise mobile phone CPU, display screen and battery, also include microcontroller and comparator, and the temperature inductor that is used to connect microcontroller and battery; Said microcontroller is connected with comparator, and mobile phone CPU is connected with microcontroller.
Wherein also include the memory that is connected with microcontroller, store the limiting threshold value and the warning comparative result threshold value of temperature alarming in this memory.
Also be provided with an on-off controller between wherein said microcontroller and the battery.
Wherein said mobile phone CPU is connected with display screen through display module.
Be provided with internal temperature in the wherein said battery and detect resistance, this internal temperature detects resistance and is connected with the said temperature inductor.
The utility model is connected with the internal temperature detection resistance of inside battery through the temperature inductor that is arranged in the mobile phone; Detected internal temperature of battery is in time sent to microcontroller; Through microcontroller relatively, if comparative result does not exceed warning comparative result threshold value, then correspondingly on display screen, show the limiting threshold value of the temperature value that obtains and temperature alarming; Remind the user to operate simultaneously, if surpass then directly cut off being connected of battery and mobile phone through on-off controller.Compared with prior art, when the utility model raises in the battery of mobile phone temperature, in time battery is managed control, effectively avoided battery of mobile phone in use Yin Wendu raise and cause the problem of blast.
