Okokuqala, ungakwazi ukuxhuma iluphu yokushaja kuluphu ekwazi ukushajwa, futhi ishaja kufanele ishintshwe ngokushesha. Ibhethri elomile kufanele lifakwe emanzini ahlanzekile noma i-sulfuric acid engu-1.050 ukuze kugcinwe ukushajwa, futhi umthamo webhethri uyatholwa.

Uma kutholakala ukuthi ayikho i-sulfate ephambene, umthamo kufanele ubuyiselwe. Okwesibili, izindleko zokulondolozwa kwebhethri elomile ngemuva kokwengezwa kokushaja okuwuketshezi kufanele zilawulwe: umkhawulo wamanje ongu-1.8a ulawulwa, ushajwa ngamahora ayi-10-15, iqembu ngalinye (3, 4) I-voltage yokushaja yebhethri ilawulwa ku-14.

7V / kuphela noma ngaphezulu Yiba. Ukuhluka kwebhethri yokuguqulwa kwebhethri kungenxa yenani eliqhubekayo lamabhethri, futhi amanzi mancane, futhi ibhethri liyavela: 1. Umthamo wokushisa uncishisiwe, isitoreji esiphezulu sokushisa singamanzi amakhulu kakhulu, ukulahlekelwa kwamanzi, umthamo wokushisa webhethri uyancipha kakhulu, futhi kukhona ukuvela Ukushisa kuyashesha kangangokuthi izinga lokushisa lebhethri liyashesha; 2.

Isiteshi se-oxygen siba bushelelezi, umoya-mpilo ovela ku-electrode enhle kulula ukufinyelela i-electrode engalungile ngokusebenzisa isiteshi; 3. Ukunamathela kwebhethri epuleti elihle nelibi liwohloka, ukumelana kwangaphakathi kuyanda, futhi ukushisa kuyanda ngesikhathi sokushaja nokukhipha inqubo. Temperatura je izjemno hitra in tvori začaran krog, to je tako imenovani termični izven nadzora, končna temperatura doseže 80 stopinj, kar povzroči deformacijo zunanjega ohišja.

Ukuhlola amaphutha kanye nokuhlonza: isethi yamabhethri Uma ekhubazekile kanyekanye, cabangela inkinga yokushintsha ishaja. Kukhona ukuguqulwa okukodwa noma oku-2 kuphela kusethi yamabhethri, kungenzeka ukuthi kulawa maphutha: 1. Ukushajwa kwebhethri kuyaguquguquka, futhi ukushajwa kwebhethri okuthile kubangela ukonakala lapho ishaja.

Lahko gre tudi za kratek stik z eno roko ali nekatere pogoje samopraznjenja. 2. Ibhethri Uma ipuleti le-polar liyi-sulfate engenakuhlehliswa, ukumelana kwangaphakathi kuyanda, futhi ukushisa okushajayo kuwukuguqulwa.

3. Ibhethri Uma uxhuma, ukusabela kubangelwa ukuwohloka kokukhiqizwa kokushisa. 4.

Ibhethri ayigcwalisi ukungezwa kwe-electrolyte ukuze kubangele ukuntuleka kwenqubo, futhi ekugcineni ukukhanya okuluhlaza akuvulwanga ngenxa yokushaja, okubangela ukuguquguquka. Ukulungiswa kanye nokucutshungulwa kwamaphutha esibili: 1. Ngesisekelo sokuqinisekisa uketshezi olungenazici, engeza uketshezi olwengeziwe ngangokunokwenzeka ukuze unwebe noma ugade ukwenzeka kokulahlekelwa ukushisa.

2. Isexwayiso sinesekhethi yangaphakathi emfushane noma isifunda esifushane esincane, futhi sinokuthambekela koku. 3.

Ngesikhathi sokusebenzisa, zama ukukhipha ngokweqile ukuvela kokukhipha ngokweqile, futhi ugcine isitoreji sakho sebhethri. 4. Ngokukhuluma hlola ishaja, akumele kusaba khona izinto ezishajwayo.

Uma ishaja emazingeni okushisa aphezulu, qiniseka ukuthi uqinisekisa ukuthi ibhethri ayihlakazeki ngokuphelele. Kulokhu, kuyadingeka ukuthatha indlela yezinyathelo zokupholisa noma ukunciphisa isikhathi sokushaja. Uma kungenjalo, yeka ukushaja.

Iphakethe lebhethri alilingani ukuze liphathe ibhalansi yamaphakethe ebhethri yinkinga egxile emhlabeni jikelele. Iphrothokholi yayo iyinhlobonhlobo. Ukuhlolwa kanye nesixazululo samaphutha 1.

Okokuqala sebenzisa ibhethri ukushaja ngokugcwele, bese uyikhipha ngesilinganiso samahora angu-2. Phakathi nenqubo yokukhipha, i-voltage yebhethri ihlale ikalwa, futhi ibhethri elibuyela emuva lomthamo wokukhipha likhethiwe ukuze lixazululwe. 2.

Okokuqala faka i-sulfate ye-dilute engu-1.050 ukuze ubone nje ukuthi kukhona i-electrolyte egelezayo, bese ushaja ngokuqhubekayo amahora angu-12-15. Naka izinga lokushisa lebhethri akumele lidlule ku-50 ¡ã C ngesikhathi sokushaja.

Ngemuva kokuthi ukushaja sekuphelile, yima amahora angu-0.5-4, uphinde usebenzise ukukhishwa kwesilinganiso samahora angu-2. Med procesom praznjenja se meri vrednost posamezne napetosti.

Če čas praznjenja ne doseže standarda ali obstaja največja razlika med najdaljšim časom praznjenja celotne baterije, je za izpolnitev zahtev potrebno tudi delovanje programa polnjenja in praznjenja. dokler. Uma iphindaphindwa umjikelezo wokushaja nokukhipha, umthamo webhethri awunaso isimemezelo noma usengu-0V kwesokunxele kanye nokucindezela okuphansi kwesokudla.

Leli bhethri ngokuvamile liyi-short-circuited noma into esebenzayo idonswe kanzima, i-sulfate eqinile engabuyiseleki emuva, njll., ayikwazi ukulungiswa, kufanele ichithwe. Kumabhethri ahlangabezana nezidingo, kufanele aphele ngaphansi kwe-voltage engaguquki engu-15V / izimo zokushaja kuphela, kanye ne-electrolyte egelezayo, sula ingaphezulu lebhethri, i-valve ye-hood, ingcina nge-PVC noma i-chloroform adhesive Fit.

Into eyodwa empilweni yebhethri ukwakheka kwamakhemikhali. Wonke umuntu uzwile ngamabhethri e-lithium-ion, noma amabhethri e-lithium polymer, kodwa lawa magama asabalele kakhulu - njengokunemba okufanayo kwenjini yomlilo yangaphakathi. Ingabe ukhuluma ngezinjini zikaphethiloli noma izinjini zikadizili, noma injini yegesi yemvelo? I-Lithium ions (en.

wikipedia.org/wiki/lithium-ion_battery) ibhekisela kubhethri esebenzisa i-lithium ion ukudlulisa amashaji. Lokhu kufaka phakathi ukwakheka kwamakhemikhali ebhethri okubanzi kakhulu.

I-Lithium polymer (en.wikipedia.org/wiki/lithium_polymer_battery) noma i-LIPO, isho kuphela iyunithi yephakethe yebhethri enezithako zamakhemikhali e-lithium ion.

Into ebaluleke kakhulu ingxenye yamakhemikhali yangempela esabela ebhethrini. Ngokuvamile kuhileleke kulokhu: i-lithium cobaltate (LiCoO2, ICR) i-lithium manganate (LiMn2O4, IMR) i-Nickel-cobalt aluminium (liniMNCO2, NCA) i-Nickel manganese cobalt (liFePO4, LFP) i-lithium titanate (LTO) ) Noma ibe nokuhlukile kwalokhu. Bese, ukwakheka kwamakhemikhali ebhethri okunikezwayo, kukhona ezinye izinto ezinomthelela omkhulu emandleni, emandleni, nasesikhathini sokuphila.

Imininingwane yokwakhiwa/ukwakheka kwe-anode ne-cathode, izingxube ezithile, nezithasiselo (okuthinta kakhulu ukusebenza kwebhethri) ziyahlukahluka kubakhiqizi abahlukene, ngisho naphakathi kwemikhiqizo ehlukene yebhethri yomkhiqizi ofanayo. Ngeshwa, iningi lale mininingwane ayitholakali nje ku-inthanethi. Ngokufanelekile, sithemba ukuthi ibhethri linomthamo omkhulu wamandla we-ultraever x (amandla engeziwe ngeyunithi ngayinye yesisindo noma isitoreji sevolumu), ukuminyana kwamandla we-ultraruff X (amandla angakhishwa ngesikhathi seyunithi), nempilo yomjikelezo ongenamkhawulo (ingasetshenziswa Abazange babe nokulahlekelwa kwamandla kuze kube sekupheleni kwendawo yonke.

Impela, kuleyondawo yonke, i-unicorn izophinde ikhiphe u-ayisikhilimu wothingo (www.youtube.com/watch?v =ybywhdlo43q) kuyishwa elikhulu, asihlali endaweni yonke ye-Utopian.

Asilandeli i-physics, umthetho wamakhemikhali, endaweni yonke yethu, ngokuvamile: ungaba nokuningi kwalokhu, kodwa ngakolunye uhlangothi, kuncane. Uma ufuna inhlanzi nebhere kube okwakho, izindleko zizofa. Ngakho-ke, asikho ngesikhathi, kunesici esikhulu ekukhetheni izimoto zikagesi.

Akekho ozosebenzisa isigidi samadola aseMelika ukuthenga imoto kagesi ngeNissan Ukulalela umoya, noma ngabe ibhethri lingamakhemikhali. Ngakho-ke, siyaqhubeka nokukhetha ukwakheka kwamakhemikhali kwangempela, okuthengekayo.
