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. Marka cadaadiska uu kor u kaco batteriga, valve badbaadada si caadi ah looma furi karo.

Muddo dheer, maadaama cadaadiska batteriga uu aad u sarreeyo, cadaadiska gaaska gudaha iyo dibaddaba waa mid aan dheellitirneyn, waxaa jiri doona ifafaale durbaannada. Labaad. Injineerada kaydinta batteriga oo si xad dhaaf ah u buuxsamay ayaa marar badan ku nuuxnuuxsaday in batteriga uu ka hortagayo qarashka xad dhaafka ah iyo daadinta xad-dhaafka ah, qarashka xad dhaafka ahna wuxuu horseedi doonaa isku-dhafka gaaska oo liita.

Waxaa jira falcelin ba&39;an oo batteriga ku jira batteriga, kaas oo leh xaddi badan oo kuleyl ah, taas oo keenta electrolytes. Burburinta gaasta, batarigu waa durbaan tumayaa. III.

Dallacadu hadda aad bay u weyn tahay. Sida ku cad tilmaamaha batteriga, batteriga BT-HSE12V ee ku dallaca batteriga hadda kama badan karo 0.25C, talooyinka lagu taliyayna waa 0.

1c (10a), iyada oo ku dallaca wakhtigan uu ka weyn yahay qiimahan macquulka ah ee hadda jira, way fududahay Hoggaanka roobabka saxanka korantada si degdeg ah, taas oo markaa keenta falcelin kiimiko ah oo ku filan. Waqtigaan, heerkulka gudaha batteriga ayaa si degdeg ah u kici doona. Haddii qiiqa uusan ku jirin waqtiga, waxaa jiri doona ifafaale durbaanka baytariga.

IV. Kharashka sabbaynaya ayaa la dhigayaa mid aad u sarreeya, dallacadu waa weyn tahay, taas oo keenaysa in o2 ee saxanka togan uu dardargeliyo, oo aan u fiicneyn sida isku-dhafka taban, kor u kaca heerkulka batteriga ayaa sidoo kale aad u dhaqso badan, qiiqa marka cadaadiska uu gaaro saxafada, batteriga VRLA waa mid qallafsan. Sababta loo garaaco batari lithium-ion baabuurka koronto: 1, tayada dallacadu waa yar tahay, qiimaha dagaalka waa la dilay, tayada xeedhiyaha ayaa hoos u dhacay, iyadoo la isticmaalayo saxan hoose, dib u habeyn ama qalab hoose oo hooseeya, qandho, xad-dhaaf ah ma aha mid sax ah, si xadka dallacadu uu yahay mid ka baxsan xakamaynta, Gaaska gudaha ee gaaska gudaha ee baakadu waxay keentaa baakidh xitaa batari ion ah.

2, wakhtiga dallacadu aad ayuu u dheer yahay, dadka isticmaala qaarkood ma haystaan ​​fikradda wakhti, iyagoo u malaynaya in gelinta ku dallacadu si toos ah u joogsanayso, ma waydiiyo, qaar xitaa buuxi laba maalmood iyo laba habeen, waxaan isticmaalay wakhti dheer, baabuur koronto ah lithium ion Nolosha batteriga ayaa khatar gelin doonta. Haddii lacag badan lagu soo dallaco waxay keeni kartaa qadar badan oo ah saxan koronto oo gaas ah, waxay sababtaa walaxda firfircoon ee gudaha inay hoos u dhacdo, soo gaabinayso nolosha batteriga, si baytarigu u noqdo mid aan waxtar lahayn, oo saameeya burburka elektrolytka, si heerkulka batteriga uu kordho, ka dhigo Drug! Daloolka waalka waa la xiray, wuxuu xoojiyaa cadaadiska gaaska gudaha wuxuu keenaa kiis batteriga inuu qalloobo, kala qaybsanaantuna waa bararan tahay. 4, iska ilow xeedhaha xajiyaha, kaliya amaahdo, ama qoys ka kooban dhowr xajiyeyaasha cabbirka baabuurta ee korontada ku shaqeeya, tani waa mid aad u badan, nooc kasta oo batari baabuur koronto ah wuxuu leeyahay interface u gaar ah, qiimaha hadda, koronto kala duwan Baabuurka waxaa laga yaabaa inuu leeyahay koronto dallacaad oo kala duwan, dallacaadda hadda way kala duwan tahay, waqtiga dallacaadda dabiiciga ah iyo waxtarka dallacadu way kala duwan yihiin, iyo dalladuhu, batterigu waa weyn yahay, batarigu waa yar yahay, dalladuhu waa yar yahay dallacaadda, kulaylka ayaa ka baxay xakamaynta, waxay noqon doontaa durbaan.

Tan sare waa sababta falanqaynta baytariyada lithium-ion, baytariyada, durbaanka baytariyada baabuurta korontada. Dhibaatooyinka badbaadada batteriga fosfooraska birta ayaa ahaa mawduuca dareenka joogtada ah ee dadku, inkastoo tignoolajiyada baytariyada lithium-ion ay si joogto ah u soo hagaagayso, laakiin khataraha badbaadada ayaa weli jira. Waxqabadka badbaadada batarigu ma laha xidhmo batari lithium-ion ka fiican.

Haddii ay jirto ifafaale bacda durbaanka inta lagu jiro isticmaalka baakadaha lithium-ion batari, taxane yar ayaa lagula talinayaa in la beddelo batteriga, ka dib oo dhan, ugu muhiimsan. 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.

Danabku wuu ka hooseeyaa 3V, marka hore samee precharge, ku dallaca hadda waa 1/10 ee hadda go&39;an, korontadu waxay kor u kacdaa 3V, geli habka dallacaadda caadiga ah. 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. Waqtigan xaadirka ah, dallacaadda hadda si tartiib tartiib ah ayaa hoos u dhacda, iyo marka hadda uu hoos u dhaco 1/10 ee hadda dallacaadda, dallacadu wuu dhammaanayaa. Tani waa habraaca kharashka guud ee baytariyada lithium-ion, haddii baytariga lithium ion ku dhex jiro aalladda casriga ah, qaabka dallacaadda waxa xakamayn doona software-ka aaladaha caqliga leh.

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. Filimka SEI ma aha mid joogto ah, waxaa jiri doona isbeddel yar inta lagu jiro habka lacag-bixinta iyo bixinta, waxaa muhiim ah in qaar ka mid ah walxaha dabiiciga ah ay isbedeli doonaan. 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.
