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. Ha khatello e phahama ka har&39;a betri, valve ea tšireletso e ke ke ea buloa ka mokhoa o tloaelehileng.

Ka nako e telele, kaha khatello ea betri e phahame haholo, khatello ea khase e ka hare le e ka ntle ha e lekane, ho tla ba le ts&39;ebetso ea meropa. Ea bobeli. Baenjineri ba libeteri tse tlatsitsoeng ho feta tekano ba hatelletse khafetsa hore betri e lokela ho thibela ho tjhaja ho feta tekano le ho tsoa ho feta tekano, mme tefiso e fetelletseng e tla lebisa ho likarolo tse mpe tsa khase ka har&39;a betri.

Ho na le karabelo e matla ea betri ka betri, e nang le mocheso o mongata, o lebisang ho electrolyte. Ho senyeha ha gasification, betri ea lla. III.

Mohala oa ho tjhaja o moholo haholo. Ho latela litaelo tsa betri, betri ea BT-HSE12V ea ho tjhaja betri ha e khone ho feta 0.25C, mme likhothaletso tse khothaletsoang ke 0.

1c (10a), ha ho tjhaja hona joale ho le kholo ho feta boleng bona bo utloahalang ba hona joale, ho bonolo Ho etella pele pula ea poleiti ea elektrode ka potlako, e leng se lebisang ho se nang lik&39;hemik&39;hale tse sa lekaneng. Ka nako ena, mocheso ka hare ho betri o tla nyoloha ka potlako. Haeba ho qeta nako ho se ka nako, ho tla ba le ts&39;ebetso ea meropa ea betri.

IV. Tefiso e phaphametseng e behiloe holimo haholo, &39;me hona joale ea ho tjhaja e kholo, e leng se etsang hore o2 ka poleiti e ntle e potlake,&39; me ha e ntle joaloka motsoako o fosahetseng, &39;me mocheso o phahama ka har&39;a betri o boetse o potlakile haholo, ho tsoa ha khatello e fihla mochine oa khatiso, betri ea VRLA e senyeha. Lebaka la koloi ea motlakase ea lithium-ion betri meropa: 1, boleng ba tjhaja bo tlase, ntoa ea theko e bolailoe, boleng ba tjhaja bo ntse bo theoha, ho sebelisoa poleiti e tlase, nchafatso kapa sesebelisoa se tlase se tlase, feberu, ho hoholeha ha parametha ha hoa nepahala, e le hore moeli oa ho tjhaja o se ke oa laoloa, Khase e ka hare ea khase e hlahisoang le ho phatloha ha betri ea lithium le khetla.

2, nako ea ho tjhaja e telele haholo, basebelisi ba bang ha ba na maikutlo a nako, ba nahana hore ho kenya mochine oa ho tjhaja o feletseng, ha ke botse, ba bang ba bile ba tlatsa matsatsi a mabeli le masiu a mabeli, ke e sebelisitse nako e telele, koloi ea motlakase lithium ion Bophelo ba pakete ea betri bo tla sokeloa. Haeba ho feta tefiso ho ka fella ka palo e kholo ea poleiti ea electrode ea khase, e etsa hore ntho e ka hare e sebetsang e theohe, e khutsufatse bophelo ba betri, e le hore betri e se ke ea e-ba lefeela, e amang ho senyeha ha electrolyte, e le hore mocheso oa betri o eketsehe, o e etse Lithethefatsi! Sekoti sa valve se koetsoe, se eketsa khatello ea khase e ka hare e etsa hore mokotla oa betri o holofale, &39;me ho arohana ho ruruhe. 4, lebala tjhaja e nang le tjhaja, alima e le &39;ngoe, kapa lelapa la lijajara tse ngata tsa koloi ea motlakase, sena se tloaelehile haholo, mofuta o mong le o mong oa betri ea koloi ea motlakase o na le sebopeho sa ona, boleng ba hajoale, motlakase o fapaneng Koloi e kanna ea ba le li-voltages tse fapaneng tsa ho tjhaja, hajoale ho tjhaja ho fapane, nako ea tlhaho ea ho tjhaja le ts&39;ebetso ea ho tjhaja li fapane, mme tjhaja, tjhaja e nyane, tjhaja e nyane, tjhaja e nyane, tjhaja e nyane. e kholo, ho tjhaja, mocheso o tsoile taolong, e tla be e lla.

Ka holimo ke tlhahlobo ea sesosa sa libeteri tsa lithium-ion, libeteri, meropa ea betri ea koloi ea motlakase. Mathata a polokeho ea pakete ea betri ea iron phosphate e bile sehlooho sa tlhokomelo e tsoelang pele ea batho, leha theknoloji ea betri ea lithium-ion e lula e ntlafala, empa likotsi tsa polokeho li ntse li le teng. Ts&39;ebetso ea polokeho ea betri ha e na pakete ea betri ea lithium-ion e betere.

Haeba ho na le ts&39;ebetso ea mokotla oa drum nakong ea tšebeliso ea lithium-ion battery packs, lihlopha tse nyenyane li buelloa ho nkela betri sebaka, ka mor&39;a tsohle, ea bohlokoa ka ho fetisisa. 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.

Motlakase o tlase ho 3V, pele o etsa precharge, hona joale ho tjhaja ke 1/10 ea sete ea hajoale, &39;me motlakase o nyolohela ho 3V, kenya mokhoa o tloaelehileng oa ho tjhaja. 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. Ka nako ena, ho tjhaja hona joale ho fokotseha butle-butle, &39;me ha hona joale ho theoha ho 1/10 ea sete ea ho tjhaja hona joale, ho tjhaja ho fela. Ena ke ts&39;ebetso ea tefiso ea betri ea lithium-ion ka kakaretso, haeba betri ea lithium ion e le teng ka sesebelisoa se bohlale, mokhoa oa eona oa ho tjhaja o tla laoloa ke software e bohlale ea lisebelisoa.

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. Filimi ea SEI ha e fetohe kamehla, ho tla ba le phetoho e nyane nakong ea tefiso le ts&39;ebetso ea ho tsoa, ​​ke habohlokoa hore lintho tse ling tse phelang li tla fetoha liphetoho. 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.
