I. Safety valve pressure over high valve controlled lead-acid battery is provided with a row of safety valves in order to ensure safe use, when the pressure in the battery rises, the safety valve will automatically open, to ensure the internal and external air pressure balance inside and outside the battery. Thaum lub siab nce hauv lub roj teeb, qhov kev nyab xeeb valve tsis tuaj yeem qhib ib txwm.

Tau ntev, txij li lub siab nyob rau hauv lub roj teeb siab dhau lawm, lub siab sab hauv thiab sab nraud tsis sib npaug, yuav muaj qhov tshwm sim ntawm lub nruas. Thib ob. Over-filled cia roj teeb engineers rov hais dua tias lub roj teeb yuav tsum tiv thaiv overcharge thiab over-discharge, thiab overcharge yuav ua rau cov roj tsis zoo nyob rau hauv lub roj teeb.

Muaj cov tshuaj tiv thaiv hnyav ntawm cov roj teeb hauv lub roj teeb, uas muaj cov cua kub ntau, uas ua rau cov electrolytes. Decompose gasification, lub roj teeb yog drumping. III.

Lub charger tam sim no loj dhau. Raws li cov lus qhia roj teeb, lub roj teeb BT-HSE12V roj teeb them tam sim no tsis tuaj yeem tshaj 0.25C, thiab cov lus pom zoo yog 0.

1c (10a), thaum them tam sim no ntau dua li qhov tsim nyog tam sim no tus nqi, nws yog ib qho yooj yim Ua rau nag lossis daus ntawm cov phaj electrode sai heev, uas ua rau muaj kev tsis txaus tshuaj lom neeg. Lub sijhawm no, qhov kub thiab txias hauv lub roj teeb yuav nce sai. Yog tias qhov tso pa tsis nyob rau lub sijhawm, yuav muaj qhov tshwm sim ntawm cov roj teeb nruas.

IV. Lub floating nqi tau teeb tsa siab dhau lawm, thiab cov nqi them tam sim no loj, ua rau o2 hauv cov phaj zoo kom nrawm, thiab nws tsis zoo li qhov tsis zoo sib xyaw, thiab qhov kub thiab txias hauv lub roj teeb kuj tseem ceev heev, hauv qhov tso pa tawm thaum lub siab ncav cuag lub xovxwm, VRLA roj teeb yog deformable. Yog vim li cas rau lub tsheb hluav taws xob lithium-ion roj teeb nruas: 1, qhov zoo ntawm lub charger yog qis, tus nqi tsov rog raug tua, lub charger zoo poob qis, siv cov phaj tsis zoo, kev kho dua tshiab los yog cov cuab yeej qis qis, kub taub hau, parameter drift tsis raug, kom lub charger txwv tsis pub dhau ntawm kev tswj, lub roj teeb sab hauv extrusion ntawm lithium ion roj teeb los ntawm cov roj teeb lithium ion deformation ntawm lub plhaub thiab cov roj teeb.

2, lub sijhawm them lub sijhawm ntev dhau lawm, qee cov neeg siv tsis muaj sijhawm lub tswv yim, xav tias ntxig qhov kev them nyiaj tag nrho tsis siv neeg nres, kuv tsis nug, qee qhov txawm tias sau ob hnub thiab ob hmo, kuv siv sijhawm ntev, lub tsheb fais fab lithium ion roj teeb lub neej yuav raug hem. Yog tias tus nqi ntau dhau tuaj yeem ua rau cov pa roj hluav taws xob ntau ntau, nws ua rau cov khoom siv hluav taws xob sab hauv poob, txo lub roj teeb lub neej, kom lub roj teeb tsis muaj txiaj ntsig, cuam tshuam rau qhov decomposition ntawm cov electrolyte, kom lub roj teeb kub nce, ua rau cov tshuaj! Lub qhov valve raug thaiv, txhim kho cov roj hauv lub siab ua rau cov ntaub ntawv roj teeb deformed, thiab qhov sib cais yog o. 4, tsis nco qab lub charger nrog charger, tsuas yog qiv ib, los yog ib tsev neeg ntawm ob peb lub tsheb fais fab loj chargers, qhov no yog heev, txhua lub tsheb fais fab roj teeb hom muaj nws tus kheej interface, tam sim no tus nqi, txawv hluav taws xob lub tsheb tej zaum yuav txawv them voltages, lub them tam sim no txawv, lub ntuj them lub sij hawm thiab kev them nqi yog txawv, thiab lub charger, lub charger yog loj, lub charger yog me me, lub charger yog me me, lub charger yog tsawg, lub roj teeb yog tsawg. ua nruas.

Cov saum toj no yog qhov ua rau kev tsom xam ntawm lithium-ion roj teeb, roj teeb, hluav taws xob tsheb roj teeb nruas. Cov teeb meem kev nyab xeeb ntawm cov hlau phosphate roj teeb pob tau yog lub ntsiab lus ntawm tib neeg txoj kev mloog mus ntxiv, txawm hais tias lithium-ion roj teeb thev naus laus zis tau txhim kho tas li, tab sis kev nyab xeeb tseem muaj. Kev nyab xeeb kev ua haujlwm ntawm lub roj teeb tsis zoo dua lithium-ion roj teeb pob.

Yog tias muaj qhov tshwm sim ntawm lub hnab nruas thaum siv hauv kev siv cov lithium-ion roj teeb pob, me-series tau pom zoo kom hloov lub roj teeb, tom qab tag nrho, qhov tseem ceeb tshaj plaws. 1. The charging process takes out the lithium ion from the positive electrode lattice under the driving process, and is embedded in the negative electrode lattice.

Qhov hluav taws xob qis dua 3V, ua ntej ua ntej, qhov them tam sim no yog 1/10 ntawm qhov teeb tsa tam sim no, thiab qhov hluav taws xob nce mus rau 3V, nkag mus rau cov txheej txheem them nqi. The standard charging process is: When the current is constant, the battery voltage rises to 4.20V, change to constant pressure charging, keep the charging voltage of 4.

20V. Lub sijhawm no, cov nqi them tam sim no maj mam txo qis, thiab thaum tam sim no poob rau 1/10 ntawm cov teeb them tam sim no, them nyiaj xaus. Qhov no yog cov txheej txheem ntawm cov roj teeb lithium-ion dav dav, yog tias lub roj teeb lithium ion muaj nyob hauv lub cuab yeej ntse, nws txoj kev them nyiaj yuav raug tswj los ntawm cov cuab yeej ntse software.

2. Battery discharge, at this time, the electronic E on the negative electrode is ran from the positive electrode through the external circuit. Come together.

By understanding the charge and discharge process of lithium-ion batteries, we can understand from microscopic, the capacity of the battery is actually the amount of charge containing the battery. The larger the current, the faster the discharge speed, the shorter the battery used. Why is the battery that the battery does not use the drum in normal use or long time? There are two phenomena in the process of charge and discharge: one.

Excessive charging caused by overcharge can result in all the lithium atoms in the positive electrode material to the negative electrode material, resulting in a transition of the positive absorbed grid, which is also an important reason for the decline in lithium-ion battery. During this process, the lithium ions of the negative electrode are increasing, and the over-accumulation allows the lithium atom to be crystallized, so that the battery is bulging. two.

In the first charge and discharge process of the liquid lithium ion battery, the electrode material is reacted on the solid-liquid phase interface in the liquid lithium ion battery, forming a passivation layer covering the surface of the electrode material. The formed passivation layer film can effectively prevent the passage of the electrolyte molecule, but Li + can be freely embedded and disengaged by the passivation layer, and has the characteristics of the solid electrolyte, so this layer of passivation film is referred to as a solid electrolyte interface mask. (SolideElectrolyteinterface), referred to as SEI.

The SEI film will protect the negative electrode material, so that the material structure is not easy to collapse, and the cycle life of the electrode material can be added. SEI zaj duab xis tsis tas li, yuav muaj kev hloov me ntsis thaum lub sij hawm them nqi thiab cov txheej txheem tawm, nws yog ib qho tseem ceeb uas qee cov organic teeb meem yuav hloov pauv. After the battery is excessively discharged, the SEI film occurs reversible to break the ring, and the SEI destruction of the negative electrode material makes the negative electrode material collapse, thereby forming a bulk phenomenon.
