Ibhetri yentsimbi yephosphate yemoto yombane kunye nendlela yokugcina ibhetri ye-ternary

Umbhali : Iflowpower - UMboneleli weSikhululo saMandla esiphathwayo

Imoto yombane i-lithium yentsimbi ye-phosphate ion ibhetri kunye ne-automobile ternary lithium ion indlela yokugcinwa kwebhetri. Okwangoku, amandla aqhelekileyo ezithuthi zamandla amatsha yinkqubo yombane, kwaye abantu bayazi ngokucacileyo, ukukhawulela ukuphuhliswa kweenkqubo zombane, kodwa ingundoqo ye-core. Okwangoku, iimoto zombane ezithengisa kwiimarike zisebenzisa iibhetri ze-lithium-ion, kodwa kukho iintlobo ezimbini zeebhetri ze-lithium-ion, iibhetri ze-lithium-ion ze-ternary kunye ne-lithium iron phosphate ion iibhetri.

Namhlanje, uXiaobian uya kwazisa imoto yombane i-lithium iron phosphate ion iibhetri kunye nemoto ye-lithium-ion yendlela yokugcina ibhetri ye-auto-dimensional three-dimensional. Indlela yokugcina imoto yombane ye-lithium iron phosphate ion ibhetri, ibambe ngokuchanekileyo ixesha lokutshaja ngexesha lokusetyenziswa, kufuneka ibambe ngokuchanekileyo ixesha lokutshaja ngokwemeko yokwenyani, bhekisa kwi-frequency yokusetyenziswa kunye ne-mileage case, bamba ukuphindaphinda. Xa uqhuba ngokuqhelekileyo, ukuba isikali sombane sibonisa ukuba ukukhanya okubomvu kunye nokukhanya okuphuzi kuvuliwe, kufuneka kuhlawulwe; ukuba kuphela isibane esibomvu sivuliwe, kufuneka siyeke ukusebenza, sihlawule ngokukhawuleza, ngaphandle koko ibhetri ikhutshwe ngokugqithisileyo iya kunciphisa kakhulu ubomi bayo.

Xa amandla egcwele ngokupheleleyo, ixesha lokubaleka lifutshane. Ixesha lokutshaja akufanele libe lide kakhulu, ngaphandle koko liya kwenza ukutshaja ngokugqithisileyo, ukwenzela ukuba ibhetri ifudumale. Ukutshaja okugqithisileyo, ukukhutshwa okugqithisileyo kunye nothintelo olungonelanga kuya kunciphisa ubomi bebhetri.

Ngokuqhelekileyo, ixesha lokutshaja eliqhelekileyo le-lithium iron phosphate ion ibhetri limalunga neeyure ezili-10. Inkqubo yokutshaja efana nobushushu bebhetri bungaphezulu kwe-65 ¡ã C, yeka ukutshaja. Okwesibini, imiyalelo yokukhusela itshaja ngokubanzi inemiyalelo yokukhusela itshaja.

Abasebenzisi abaninzi abajongi imikhwa yencwadana. Ukongeza kwingxaki, ndifuna ukufumana imiyalelo kwixesha elizayo, ngokuphindaphindiweyo emva kwexesha, ngoko ndiya kuqala ukujonga imiyalelo iyimfuneko kakhulu. Ukuze kuncitshiswe iindleko, itshaja yangoku ayilungiswanga ngokusisiseko kunye nokungcangcazela okuphezulu, ukwenzela ukuba itshaja ayifanele ibekwe kwi-trunk kunye nebhasikithi yeebhayisikili zombane.

Kwiimeko ezikhethekileyo, kufuneka uhambe, kodwa uphinde upakishe itshaja ngeplastiki ye-foam, uthintele i-vibration. Iitshaja ezininzi ziye zadlula kwi-vibrations, kwaye ii-potentiometers zazo zangaphakathi ziya kukhukuliseka, ukuze yonke ipharamitha ikhukuliswe, okukhokelela kwimeko yokutshaja engaqhelekanga. Ukongezelela, kukuhlawula ingqalelo ekuhlawuleni umoya we-ventilation weshaja, ngaphandle koko akuyi kuchaphazela kuphela ubomi beshaja, kodwa kunye ne-thermal drift inokuchaphazela imeko yokutshaja.

Oku kuya kwenza umonakalo kwibhetri. Ngoko ke, kubaluleke kakhulu ukukhusela itshaja. Okwesithathu, ibhetri edityanisiweyo rhoqo iqhuba ukukhutshwa okunzulu ikwanceda ibhetri "yokuvula", enokuphucula kancinci umthamo webhetri.

Indlela eqhelekileyo kukukhupha ibhetri ngamaxesha athile. Indlela ekhutshwe ngokupheleleyo kukukhwela ukhuseleko lokuqala lwe-undervoltage phantsi komthwalo oqhelekileyo wepavement flat. Qaphela ukuba sigxininisa ngokukodwa ukukhuselwa kwe-undervoltage yokuqala.

Emva kokukhuselwa kwe-undervoltage yokuqala, ibhetri iya kuvuka emva kwexesha elithile, kwaye ibuyisele kwimeko engaphumiyo, ngeli xesha, ukuba ibhetri isetyenziswe, iyingozi kakhulu kwibhetri. Emva kokugqiba ukukhupha ngokupheleleyo, tshaja ibhetri ngokupheleleyo. Iya kuziva ukuba umthamo webhetri uphuculwe.

Okwesine, iplagi ishushu iplagi yokubonelela nge-volts engama-220 okanye iplagi yokuphuma kwetshaja ikhululekile, kwaye i-oxidation yendawo yoqhagamshelwano inokubangela ukuba iplagi ixhonywe, ixesha lokudlulisa ubushushu liya kubangela iplagi isiphaluka esifutshane okanye umfowunelwa, ukonakalisa itshaja kunye nebhetri, ikuzise ilahleko engadingekile. Ngoko ke, xa ufumana oku ngasentla, kufuneka ucoce i-oxide okanye ubuyisele isinxibelelanisi ngexesha. 5.

Nangona uhlawula, nokuba amandla akho okuhlaziya akude, ungayisebenzisa i-2 kwiintsuku ze-3, kodwa kucetyiswa ukuba uhlawule yonke imihla, ukwenzela ukuba ibhetri ibe kumjikelezo ongekho nzulu, ubomi bebhetri buya kwandiswa. Ukusetyenziswa kwangethuba kwabasebenzisi befowuni ephathwayo bacinga ukuba ibhetri yeyona ilungileyo ukuyisebenzisa emva kokuba igcwaliswe ngokupheleleyo. Le mbono ayilunganga.

Imemori yebhetri ayomelele kangako. Hlala ubeka ubomi bebhetri bukhulu kakhulu. Uninzi lweetshaja zibonisa ukuba ukukhanya okwenziwe ukukhanya kubonisa ukuba ibhetri inokutsalwa kumbane we-97% ukuya kwi-99%.

Nangona kuphela i-1% ukuya kwi-3% yombane, impembelelo yokuqhubeka komthamo iphantse ingahoywa, kodwa iya kwenza kwakhona ukuqokelela phantsi kwentlawulo, ngoko ibhetri izaliswe ngokutshintsha kombane, kwaye intlawulo edadayo iya kuqhubeka kangangoko kunokwenzeka, kwaye i-vulcanization yebhetri nayo inenzuzo. Okwesithandathu, kunqatshelwe ngokungqongqo ukuba ibe yilahleko xa igcinwe kwindawo yokugcina enqatshelwe ngokungqongqo. Ukulahlekelwa yilahleko kuthetha ukuba akukho ukutshaja kwangethuba emva kokuba ibhetri isetyenzisiwe.

Ibhetri ifakwe ekulahlekeni kwelahleko, ixhomekeke kwi-sulfate, i-crystal ekhokelayo ye-sulfate ifakwe kwi-plate, eya kuthintela ishaneli ye-ion, ibangele ukutshaja okunganeleyo, kunye nomthamo webhetri uyancipha. Okukhona ixesha lelahleko lide, kokukhona ibhetri yonakala. Ngoko ke, xa ibhetri ingasebenzi, kufuneka yongezwe kanye ngenyanga, ukuze impilo yebhetri ibe ngcono.

7. Ukuthintela ukukhutshwa okukhulu kwangoku imoto yombane iqala, iqhutywe, inyuka, zama ukuyithintela ekukhawuleziseni ukukhawuleza, ukwenza ukukhutshwa kwangoku ngokukhawuleza. Ukukhutshwa okukhulu ngoku kunokubangela iikristale zelothe zesulfate, ngaloo ndlela zonakalise iipropathi ezibonakalayo zepleyiti yeplate yebhetri.

Indlela yokugcinwa kwebhetri ye-lithium-ion yemoto ye-thith-dimensional ye-lithium-ion Okwangoku, uhlobo oluqhelekileyo lwesithuthi samandla esitsha se-lithium-ion ibhetri yi-ion-dimensional ion battery kunye ne-lithium iron phosphate ion ibhetri. Phakathi kwabo, ibhetri ye-lithium-ion ene-dimensional-dimensional inendima enkulu, kuba ibhetri ye-lithium ion ye-ternary incinci, ukuxinwa kwekhono kuphezulu, ukumelana nobushushu obuphantsi, kunye nokusebenza komjikelo kukwangcono, ngoko ke ukuba yinto ehamba phambili yemoto entsha yomkhweli. Ukuba ibhetri ayisetyenziswanga ixesha elide, kukhethwa ukuba isixa sombane esihlawuliswayo ukusuka malunga ne-40% sigcinwe kubushushu obuyi-10 ~ 30 ¡ã C, kwaye umbane wongezwa rhoqo kwisiqingatha sonyaka; Ibhetri ye-lithium ion yokukhusela ukuhlawulisa kunye nokukhupha I-voltage yangoku ineemfuno ezingqongqo kakhulu, ukwenzela ukukhusela ibhetri ingonakaliswa ngenxa yendawo yombane yangaphandle, umzimba webhetri uya kumisela i-chip yesimo sebhetri.

Le chip nayo inemisebenzi yokurekhoda umthamo webhetri kunye nokulungisa umthamo webhetri. Ngoku, nokuba ibhetri yeselula ye-cottage ayigcini esi sitshixo ukukhusela i-chip, ngaphandle koko ibhetri yeselula ye-cottage ayisetyenziswanga ixesha elide; Impembelelo yenkumbulo ixhaphakile kwibhetri yokutshaja i-nickel-hydrogen. Ukusebenza okuthe ngqo kukuba: Ukuba uqala ukusebenzisa ibhetri ixesha elide, ibhetri iya kwaliwa kakhulu, nokuba ufuna ukugcwala, ayigcwali.

Ngoko ke, indlela ebalulekileyo yokugcina ibhetri ye-nickel-hydride kukuba umbane kufuneka usetyenziswe ngaphambi kokuba uqalise ukutshaja, ugcwele umbane uvumelekile ukuba usebenzise. Impembelelo yememori yebhetri ye-lithium-ion esetyenziswa ngokuqhelekileyo ngoku incinci ukuba ingahoywa. Iibhetri ze-Lithium ion zisetyenziselwa ukusebenzisa iibhetri ze-lithium-ion ngenxa yomthamo wazo omkhulu, akukho mphumo yememori, iindawo ezininzi nangaphezulu.

Kwimarike yogcino lwamandla, ixhamle kwezinye iinkampani zebhetri ye-lithium ukuqala ishishini lokugcina amandla, kwaye imfuno yentengiso yeebhetri ze-lithium iron phosphate ion iqala ukukhula.
