Isishwankathelo seemodyuli zebhetri
Iimodyuli zebhetri ziyinxalenye ebalulekileyo yezithuthi zombane. Umsebenzi wazo kukudibanisa iiseli ezininzi zebhetri ukuze zenze i-whole ukuze zinike amandla aneleyo ukuba izithuthi zombane zisebenze.
Iimodyuli zebhetri zizinto zebhetri ezenziwe ziiseli zebhetri ezininzi kwaye ziyinxalenye ebalulekileyo yezithuthi zombane. Umsebenzi wazo kukudibanisa iiseli zebhetri ezininzi ukuze zenze i-whole ukuze zinike amandla aneleyo kwizithuthi zombane okanye imisebenzi yokugcina amandla. Iimodyuli zebhetri azingomthombo wamandla wezithuthi zombane kuphela, kodwa zikwayenye yezona zixhobo zazo zibalulekileyo zokugcina amandla.
Ukuzalwa kweemodyuli zebhetri
Ngokwembono yoshishino lokuvelisa oomatshini, iibhetri zeseli enye zineengxaki ezifana neempawu ezimbi zoomatshini kunye nokudibana kwangaphandle okungenabuhlobo, ikakhulu kuquka:
1. Imeko yangaphandle yomzimba efana nobukhulu kunye nembonakalo ayizinzanga, kwaye iya kutshintsha kakhulu ngenkqubo yomjikelo wobomi;
2. Ukungabikho kofakelo olulula noluthembekileyo loomatshini kunye ne-interface yokulungisa;
3. Ukungabikho konxibelelwano olulula lwemveliso kunye ne-interface yokujonga imeko;
4. Ukhuseleko olubuthathaka loomatshini kunye nolwe-insulation.
Ngenxa yokuba iibhetri zeseli enye zineengxaki ezichazwe apha ngasentla, kuyimfuneko ukongeza umaleko ukuze zitshintshe kwaye zisombululwe, ukuze ibhetri ikwazi ukuhlanganiswa kwaye idityaniswe nesithuthi sonke ngokulula. Imodyuli eyenziwe ziibhetri ezininzi ukuya kwezilishumi okanye ezingamashumi amabini, ezinemeko yangaphandle ezinzileyo, i-mechanical elula nethembekileyo, i-output, i-monitor interface, kunye ne-insulation ephuculweyo kunye nokukhuselwa kwe-mechanical sisiphumo solu khetho lwendalo.
Imodyuli esemgangathweni yangoku isombulula iingxaki ezahlukeneyo zeebhetri kwaye inezi nzuzo zilandelayo:
1. Inokwenza imveliso ezenzekelayo ngokulula kwaye inempumelelo ephezulu yemveliso, kwaye umgangatho wemveliso kunye neendleko zemveliso kulula ukuzilawula;
2. Ingenza umgangatho ophezulu wokwenziwa kwemigangatho, okunceda ekunciphiseni kakhulu iindleko zemigca yemveliso nokuphucula ukusebenza kakuhle kwemveliso; iindlela ezisemgangathweni zokunxibelelana kunye neenkcukacha zilungele ukhuphiswano olupheleleyo lwemarike kunye nokukhetha iindlela ezimbini, kwaye zigcina ukusebenza okungcono kokusetyenziswa kwe-cascade;
3. Ukuthembeka okugqwesileyo, okunokubonelela ngokhuseleko olufanelekileyo loomatshini kunye nokukhusela iibhetri kulo lonke ixesha lobomi;
4. Iindleko zezinto eziluhlaza eziphantsi kakhulu aziyi kubeka uxinzelelo olukhulu kwiindleko zokugqibela zokuhlanganisa inkqubo yamandla;
5. Ixabiso eliphantsi leyunithi enokugcineka lincinci xa lithelekiswa nexabiso leyunithi, nto leyo enefuthe elikhulu ekunciphiseni iindleko emva kokuthengisa.
Ulwakhiwo lwemodyuli yebhetri
Ulwakhiwo lwemodyuli yebhetri ludla ngokuquka iseli yebhetri, inkqubo yolawulo lwebhetri, ibhokisi yebhetri, isixhumi sebhetri kunye nezinye iindawo. Iseli yebhetri yeyona nto iphambili kwimodyuli yebhetri. Yenziwe ziiyunithi ezininzi zebhetri, ngokuqhelekileyo ibhetri ye-lithium-ion, eneempawu zoxinano lwamandla aphezulu, izinga eliphantsi lokuzikhupha kunye nobomi benkonzo ende.
Inkqubo yolawulo lwebhetri ikhona ukuqinisekisa ukhuseleko, ukuthembeka kunye nobomi obude bebhetri. Imisebenzi yayo ephambili ibandakanya ukujonga imeko yebhetri, ulawulo lobushushu bebhetri, ukhuseleko lokutshaja/ukukhupha ibhetri ngaphezulu, njl.
Ibhokisi yebhetri liqokobhe langaphandle lemodyuli yebhetri, elisetyenziselwa ukukhusela imodyuli yebhetri kwimeko-bume yangaphandle. Ibhokisi yebhetri idla ngokwenziwa ngezinto zesinyithi okanye zeplastiki, ezinokumelana nokugqwala, ukumelana nomlilo, ukumelana nokuqhuma kunye nezinye iimpawu.
Isixhumi sebhetri yinxalenye edibanisa iiseli ezininzi zebhetri zibe yinto epheleleyo. Ngokwesiqhelo yenziwe ngezinto zobhedu, enomoya ovumayo, ukumelana nokuguguleka kunye nokumelana nokugqwala.
Izalathi zokusebenza kwemodyuli yebhetri
Ukumelana kwangaphakathi kubhekisa kukumelana kombane ohamba ngebhetri xa ibhetri isebenza, okuchatshazelwa zizinto ezifana nezinto zebhetri, inkqubo yokuvelisa kunye nolwakhiwo lwebhetri. Yahlulwe yaba kukumelana kwangaphakathi kwe-ohmic kunye nokumelana kwangaphakathi kwe-polarization. Ukumelana kwangaphakathi kwe-ohmic kwenziwa kukumelana koqhagamshelwano lwezinto ze-electrode, ii-electrolytes, ii-diaphragms kunye neendawo ezahlukeneyo; ukumelana kwangaphakathi kwe-polarization kubangelwa yi-electrochemical polarization kunye ne-concentration difference polarization.
Amandla athile – amandla ebhetri ngeyunithi nganye yomthamo okanye ubunzima.
Ukusebenza kakuhle kokutshaja nokukhupha umbane – umlinganiselo womlinganiselo apho amandla ombane asetyenziswa yibhetri ngexesha lokutshaja aguqulwa abe ngamandla eekhemikhali anokugcinwa yibhetri.
I-Voltage - umahluko onokubakho phakathi kwee-electrode ezilungileyo nezingalunganga zebhetri.
I-voltage yesekethe evulekileyo: i-voltage yebhetri xa kungekho circuit yangaphandle okanye umthwalo wangaphandle oqhagamshelweyo. I-voltage yesekethe evulekileyo inobudlelwane obuthile nomthamo oseleyo webhetri, ngoko ke i-voltage yebhetri idla ngokulinganiswa ukuqikelela umthamo webhetri. I-voltage esebenzayo: umahluko onokubakho phakathi kwee-electrodes ezilungileyo nezingalunganga zebhetri xa ibhetri ikwimeko yokusebenza, oko kukuthi, xa kukho umbane odlula kwisekethe. I-voltage yokucima umbane: i-voltage efikelelwe emva kokuba ibhetri itshajwe ngokupheleleyo kwaye ikhutshiwe (ukuba ukukhupha kuyaqhubeka, kuya kukhutshwa kakhulu, nto leyo eya konakalisa ubomi kunye nokusebenza kwebhetri). I-voltage yokucima umbane: i-voltage xa umbane oqhubekayo utshintsha uye kwi-voltage eqhubekayo xa kutshajwa.
Izinga lokutshaja kunye nokukhupha ibhetri – khupha ibhetri ngomsinga osisigxina we-1H, oko kukuthi, i-1C. Ukuba ibhetri ye-lithium ilinganiswe kwi-2Ah, ngoko i-1C yebhetri yi-2A kwaye i-3C yi-6A.
Uqhagamshelo oluhambelanayo – Umthamo weebhetri ungandiswa ngokuzidibanisa ngaxeshanye, kwaye umthamo = umthamo webhetri enye * inani loqhagamshelo oluhambelanayo. Umzekelo, imodyuli yeChangan 3P4S, umthamo webhetri enye yi-50Ah, emva koko umthamo wemodyuli = 50*3 = 150Ah.
Uqhagamshelo lwechungechunge – I-voltage yeebhetri inokwandiswa ngokuzidibanisa ngochungechunge. I-voltage = i-voltage yebhetri enye * inani leentambo. Umzekelo, imodyuli yeChangan 3P4S, i-voltage yebhetri enye yi-3.82V, emva koko i-voltage yemodyuli = 3.82*4 = 15.28V.
Njengenxalenye ebalulekileyo kwizithuthi zombane, iimodyuli zebhetri ye-lithium yamandla zidlala indima ebalulekileyo ekugcineni nasekukhupheni amandla ombane, ukubonelela ngamandla, nokulawula nokukhusela iipakethe zebhetri. Zinomahluko athile kwindlela ezibunjwe ngayo, umsebenzi, iimpawu kunye nokusetyenziswa kwazo, kodwa zonke zinempembelelo ebalulekileyo ekusebenzeni nasekuthembekeni kwezithuthi zombane. Ngokuqhubeka kweteknoloji kunye nokwandiswa kwezicelo, iimodyuli zebhetri ye-lithium yamandla ziya kuqhubeka nokuphuhlisa kwaye zenze igalelo elikhulu ekukhuthazeni nasekuthandeni izithuthi zombane.
