Description
Technical field
This utility model relates to a kind of charge protection device, is specifically related to a kind of lithium ion battery and charger baby charge protection device.
Background technology
Since lithium ion battery and charger baby emerge, battery or charger baby burn when charging, the report that explodes is of common occurrence, and the fire incident caused by burning or exploding causes great injury to even result in client to client therefore to get killed.Analysis cause of accident understands, and battery explosion or burning main cause have the most several: 1, place's ambient temperature is the highest, causes electrolyte to be decomposed, and battery expands rapidly, bulge, rupture, and then burns, explodes；2, sealing the standard that is not reaching to during packaging, battery is used inferior materials and turned out substandard goods when assembling, is caused potential safety hazard；3, battery the most also can be decomposed because of electrolyte and be caused battery bulge phenomenon, or inside battery occurs analysis lithium phenomenon, forms Li dendrite, pierces through barrier film, cause internal short-circuit of battery, generate heat in a large number, cause cells burst, even explode；4, battery charger apparatus may cause momentary charge electric current excessive, causes battery-heating, causes battery explosion.
It can thus be seen that battery inferior, charger, improperly using method inferior, being in for a long time under the too high environment of temperature, the most original-pack battery uses long-time, is all likely to result in battery explosion.The cells burst explosion accident that major part makes a very bad impression all occurs when battery charges.If having a kind of explosion-proof, fire-retardant cell safety charging device, it is possible to floor level is down in harm, there is presently no the cell safety charging device of a the type.
Utility model content
This utility model unpredictably can burn when charging mainly for current lithium ion battery and charger baby and even explode, the problem that there is potential safety hazard, it is provided that a kind of lithium ion battery and charger baby charge protection device.
This utility model is that the technical scheme that solution the problems referred to above are taked is:
nullA kind of lithium ion battery and charger baby charge protection device，Including upper casing and lower casing，Upper casing and lower casing are connected by axle and can open and close，Wherein: equipped with control module on the outer surface of upper casing、Display lamp、Alarm and miniature dry powder extinguisher tank，The shower nozzle of miniature dry powder extinguisher tank passes upper casing and extends to the inside of upper casing，Display lamp includes four LED lights，It is respectively red light、Amber light、Blue lamp and green light，Temperature sense probe it is provided with in upper casing，Side in lower casing is provided with box，Opposite side in lower casing is provided with support，Be positioned at support side on the inner surface of lower casing is arranged over mini-fan，Box is provided with some through holes，Switch it is provided with in box、Socket and adsorbent tank，Socket be arranged in box near the side of support and for uncovered can be with external connection，Switch and socket are connected by wire，Switch and be connected with extraneous power supply also by wire，Described control module is popped one's head in temperature sense respectively、Display lamp、Alarm、Miniature dry powder extinguisher tank、Mini-fan is connected with switch，Temperature sense probe sends the temperature signal of collection to control module，Control module receive after temperature signal with the A of record in control module、Tri-threshold values of B and C compare，When temperature signal is less than threshold value A，Control module controls display lamp and mini-fan simultaneously，Mini-fan is opened，The green light of display lamp lights and charges normal to represent；When temperature signal is more than or equal to threshold value A, control module controls display lamp and alarm simultaneously so that the blinking red lamp of display lamp, and alarm equipment alarm is to represent that needs are adjusted, away from temperature higher position；When temperature signal is more than or equal to threshold value B, control module controls switch, display lamp and alarm simultaneously so that switch cuts out power-off, and the amber light flicker of display lamp and alarm equipment alarm are to represent power-off, but still have certain danger please don't be close；When temperature signal is more than or equal to threshold value C, control module controls miniature dry powder extinguisher tank, display lamp and alarm simultaneously so that miniature dry powder extinguisher tank is opened, and the blue lamp flicker of display lamp and alarm equipment alarm are to represent that battery burns, please don't be close, need to withdraw.
Sorbent material in adsorbent tank described in the utility model is the one in silica gel particle, kieselguhr, activated alumina, absorbent charcoal material, aeroge, molecular sieve, hygroscopicity macromolecular material.
Described upper casing and lower casing are all made up of the stainless steel being resistant to 0.1～5Mpa pressure.
Position of center line at upper casing arranges a slideway, and temperature sense probe is arranged on slideway can be slided along slideway by pulley.
This utility model uses technique scheme, can effectively prevent the generation of blast, remove a hidden danger.In this utility model, threshold value A is 40 DEG C, and threshold value B is 80 DEG C, and threshold value C is 150 DEG C, and concrete reason is as follows:
During owing to charging to lithium ion battery or charger baby, battery or charger baby itself can be generated heat, if be placed in radiating condition bad in the environment of, heat will gather increase, cause battery overheated, battery is overheated it is possible to cause the thawing of battery diaphragm, and then is shorted in causing battery and causes cells burst even to explode.Finding out battery temperature the most in time necessary, threshold value A is just set as 40 DEG C.
Electrolyte lithium hexafluoro phosphate LiPF6Being a heat-labile compound, be chronically under 80 DEG C of high temperature above environment, lithium hexafluoro phosphate can occur to decompose as follows:
Wherein: phosphorus pentafluoride PF5 is a kind of super strong lewis acid, moment can capture the electrolyte solvent oxygen atoms such as ethylene carbonate, produce a large amount of fluohydric acid gas.And the hydrogen that fluohydric acid gas and lithium metal moment produce is only the basic reason of blast.Therefore threshold value B is set to 80 DEG C.
Once battery burns, and temperature can rise to 150～300 DEG C soon, in order to harm be preferably minimized, threshold value C is set to 150 DEG C.
