Nangona ibhetri ye-lead-asidi inophuculo olukhulu kuyilo lolwakhiwo kunye nokusetyenziswa kwemathiriyeli ekrwada, ukusebenza kunophuculo olubonakalayo, uninzi loyilo kunye nokugcinwa kwe-asidi ye-asidi ye-lead-free iintlawulo ezidadayo ezidadayo zi-15 ~ Ngaphezu kweminyaka engama-20, kodwa ibhetri enokufikelela ngokwenene kubomi obunjalo mhlawumbi ingaphantsi. 1) Uyilo lwezixhobo zokutshaja alufezekanga, alulungele ukusebenzisa. I-2) Ukuba ibhetri ikhutshwe, ayiyi kuxhaswa ngexesha, ngakumbi ukukhutshwa ngokugqithiseleyo kubangele ukulimala okubulalayo.

I-3) Umgangatho weemveliso zabakhiqizi abambalwa abahlwempuzekileyo, kwaye bazaliswe ngamaxesha. Itekhnoloji yokutshaja ibhetri ifuna abavelisi baqinisekise ukuba izalathisi zobugcisa zobomi benkonzo zinikwa kumaqondo obushushu obungange 25 ¡ã C. Ekubeni amandla ombane ebhetri ekhokelela kwimonomer anobushushu obuphantsi malunga ne-4 mV ngokunyuka kwe-1 ¡ã C, ibhetri ye-12V equka iibhetri ze-monomer ezintandathu, amandla ombane wentlawulo edadayo kwi-25 ¡ã C yi-13.

5V; xa ubushushu be-ambient buncitshisiwe ukuya ku-0 At ¡ã C, intlawulo edadayo kufuneka ibe yi-14.1V; xa ubushushu be-ambient bunyuka ukuya kwi-40 ¡ã C, intlawulo edadayo kufuneka ibe yi-13.14V.

Kwangaxeshanye, ibhetri ye-lead-asidi inophawu lokuba xa ubushushu be-ambient buhlala buqinile, i-voltage ye-charge yi-100mV ephezulu, kwaye umsinga wokutshaja uya kunyuka amaxesha amaninzi, ngoko ke i-thermal ephuma ekulawuleni ibhetri iya kubangela ilahleko yobushushu bebhetri kunye nomonakalo ogqithisiweyo. Xa i-voltage yokutshaja i-100mV ene-voltage ephantsi, iya kubangela ukuba ibhetri ihlawule ibhetri, kwaye ibhetri yonakaliswe. Ukongezelela, umthamo webhetri ye-lead-acid nayo ihambelana nokushisa, malunga ne-1 ¡ã C, eya kuhla nge-1 ¡ã C, kwaye umenzi ufuna ukuba umenzi akhuphe ukusuka kwi-50% yomthamo olinganisiweyo kwibhetri yasehlobo, emva kokuba ubusika bukhuphe i-25%.

Kufuneka ihlawulwe ngexesha. Ngokucacileyo, ibhetri ye-lead-acid ekusetyenzisweni kwansuku zonke ayinakwenzeka kwindawo ye-12 ¡ã C ixesha elide, kwaye kukho ukuhluka kweqondo lokushisa kwintlukwano yeqondo lokushisa emini, kwaye ungakhankanyi entwasahlobo, ehlobo, ekwindla, nasebusika. Umahluko wamaqondo obushushu, ke ngoko kukho iindlela ezahlukeneyo zokulungisa i-thyristor, ukulungiswa kwebhaki ye-transformer, kunye nokutshintsha okuqhelekileyo okulawulwayo kohlobo lonikezelo lwamandla ebhetri itshaja yelead-asidi, engumbane ongaguqukiyo okanye itshaja yebhetri yeasidi engaguqukiyo yangoku.

Iimfuno ezingqongqo zobuchwephesha ezingenako ukukhawulelana nentlawulo yebhetri yelead-asidi. Kuzo zonke ezi ndlela zokutshaja iibhetri ze-lead-acid, kunye neeshaja zebhetri ze-lead-acid eziphuhliswe ngokwezi ndlela, asikho nzima ukubona ukuba iteknoloji ayifezekanga, kwaye ibhetri ye-lead-acid ihlawuliswa ngale mveliso. Ukuchaphazela ubomi bebhetri ye-lead-acid, ngelixa ezi tshaja zineengxaki nge-voltage yokusebenza encinci, umthamo omkhulu, ukusebenza kakuhle okuphantsi, into yokhuseleko.

Itshaja yebhalansi yendalo yeyokuxhaphaka kokutshaja kwebhetri yelead-asidi engentla, iChangsha Yuxi Electronics Co., Ltd. inophononongo lwexesha elide lwetshaja ye-lead-asidi yebhetri ixesha elide, enendlela yayo eyodwa kunye noyilo olukrelekrele ukuvelisa ukutshaja okutsha.

Iimveliso zochungechunge, ukusombulula iingxaki zobugcisa ezintsonkothileyo kwiibhetri ze-lead-acid, ezingqinwe kwiminyaka emininzi yovavanyo, zandisa kakhulu ubomi beebhetri ze-lead-acid. (Obu buchwephesha busetyenziselwe ilungelo elilodwa lomenzi wechiza) indlela yokulinganisa yendalo yokutshaja ibhetri? Kukho izixhobo zombane ezimbini EA, EB. Xa umthombo wamandla u-EA ukwiqondo lobushushu elifanayo le-ambient, i-electrode efanelekileyo kunye ne-electrode efanelekileyo ziqhagamshelwe, i-electrode engalunganga idityaniswe ne-electrode engalunganga, Phakathi kwabo, kukho ubudlelwane bokuba kukho ubudlelwane.

Ukuba i-EA iphezulu, i-EB iya kubonelela nge-EA-EB kwi-EB =δE yombane, iyaδUbungakanani be-E, nikezela enyeδi ngoku kunikezelo lwamandla EB flow kunye neperfuse, xa EB ifunxa unikezelo EAδMna okwangoku, ukwenzela ukuba i-EB iphakame kwi-EB (kwibhetri, i-voltage ye-battery-end iyanda kunye nenani lemali yokugcina intlawulo), umthombo wamandla we-EA uya kumisa ukubonelela ngoku kumbane we-EB, eyi-EA = EB,δE = 0,δmna =0. Kule nkcazo ingentla, sithatha indawo ye-EB ukuba ihlawulwe, ibalwa kwi-voltage ehambelana nebhetri kwiindawo ezahlukeneyo zokukhupha kunye namaqondo okushisa aphakathi. I-EA yenzelwe ngononophelo kumaqondo okushisa ahlukeneyo, kwaye ukunikezelwa kwamandla ombane ophumayo kunye nangoku kunokulungiswa ngokuzenzekelayo ngokwebhalansi yokutshaja ibhetri.

Kwimeko yokulungiswa ngokupheleleyo, umbane we-EA unokuhlawula ibhetri ngokwebhetri, kwaye ibhetri inokuhlawuliswa ngokwebhetri, kwaye ibhetri ihlawuliswe ngokupheleleyo.δE = 0,δi = 0, amandla e-EA akasayi kuphinda asebenzise amandla. Ukususela ngoko, i-EA itshintsha kuphela ubushushu be-ambient, kunye ne-battery yokutshaja i-battery yokulandelela ibhalansi yembuyekezo, kuba yonke inkqubo yokutshaja ibhetri izenzekelayo ngokupheleleyo, ngoko siyibiza ngokuba yi-balance balance Law.

Le ndlela ilungele ngokupheleleyo: ibhetri iyahluka emva kokuba ibhetri ihlawulisiwe, kwaye umehluko wevoltage phakathi kwe-EA kunye nebhetri yokutshaja i-EB iyahluka.δE = 0, indaloδi = 0, ekubeni i-EA ayinayo ibhetri yombane (EB), ibhetri ye-electrolyte ayikwazi ukubilisa, kwaye akunakwenzeka ukubola amanzi kwi-electrolyte kwibhetri, akunakwenzeka ngakumbi ukunyusa uxinzelelo kunye nobushushu kwibhetri, kubonakala iingozi zoKhuseleko. Ngoko ke, indlela inikezelwa kwibhetri engavumeli ukuba ibhetri ihlawule, kwaye ayiyi kuyenza intlawulo yebhetri, kodwa ilungele ngakumbi, ikhuselekile, ithembekile.

Ukususela kolu hlalutyo lungasentla, asikho nzima ukubona ukuba le ndlela ifaneleke ngokukodwa ukugcinwa kwe-free kunye nokugcinwa okuncinci kwebhetri ye-lead-acid, enokuthi ivumelane nokugcinwa kwebhetri yemihla ngemihla yokukhutshwa okungapheliyo, okufanelekileyo ekuphuculeni ukusetyenziswa kwansuku zonke kwebhetri. Ukuthembeka, ukuphucula ubomi benkonzo yebhetri. Okwesibini, uhlalutyo ngokwembono yokufunda imathiriyeli.

Ukuza kuthi ga ngoku, iToyota kuphela ifumene into eyomeleleyo, eyahluke ngokupheleleyo kwizinto zeferrite ezisetyenziswa kwibhetri ye-lithium ion, enokunciphisa ibhetri ye-lithium-ion ibhetri, enokunciphisa ngama-70. % Ubushushu. Nangona kunjalo, nokuba kukho ukutya okuninzi, iToyota ayinakuchaza ukuba akukho nkqubo yokupholisa ibhetri ayisekho.

Ukongeza, ukongeza kule nto eyomeleleyo, akukho lwazi oluye lwabonakaliswa lunento engeyiyo imfiva yokugqiba ukuhlawuliswa kunye nokukhutshwa. Ke ukusuka kule angle, ndiyoyika ukuba kunzima ukufezekisa ukupholisa kwebhetri.
