Ukuzalwa kweemodyuli zebhetri

Ngokwembono yoshishino lokwenziwa koomatshini, iibhetri ezineseli enye zineengxaki ezinje ngeepropathi ezibuthathaka zoomatshini kunye nojongano lwangaphandle olungenabubele, ngakumbi kubandakanya:

1. Isimo somzimba sangaphandle esinjengobukhulu kunye nenkangeleko ayizinzile, kwaye iya kutshintsha kakhulu kunye nenkqubo yomjikelezo wobomi;

2. Ukungabikho kofakelo olulula noluthembekileyo lomatshini kunye nokulungisa ujongano;

3. Ukunqongophala koqhagamshelo oluluncedo lwemveliso kunye nojongano lobume bemeko;

4. Ubuthathaka bokukhuselwa komatshini kunye ne-insulation.

Ngenxa yokuba iibhetri zeseli enye zineengxaki ezingentla, kuyimfuneko yokongeza umaleko ukuze utshintshe kwaye uzisombulule, ukwenzela ukuba ibhetri ihlanganiswe kwaye idibaniswe kunye nesithuthi sonke ngokulula.Imodyuli yenziwe ngeebhetri ezininzi ukuya kweshumi okanye ezingamashumi amabini, ezinesimo sangaphandle esizinzile, esifanelekileyo kunye nesithembekileyo ngoomatshini, imveliso, i-interface yokubeka iliso, kunye ne-insulation eyandisiweyo kunye nokhuseleko lomatshini sisiphumo solu khetho lwendalo.

Imodyuli esemgangathweni yangoku isombulula iingxaki ezahlukeneyo zeebhetri kwaye inezi zinzuzo zilandelayo:

1. Iyakwazi ukuqonda ngokulula imveliso ezenzekelayo kwaye inemveliso ephezulu, kwaye umgangatho wemveliso kunye neendleko zokuvelisa kulula ukulawula;

2. Inokwenza umgangatho ophezulu wokulinganisa, onceda ukunciphisa kakhulu iindleko zemveliso kunye nokuphucula ukusebenza kakuhle kwemveliso;ujongano olusemgangathweni kunye neenkcukacha zikhokelela kukhuphiswano olupheleleyo lwemarike kunye nokukhetha iindlela ezimbini, kunye nokugcina ukusebenza okungcono kokusetyenziswa kwe-cascade;

3. Ukuthembeka okugqwesileyo, okunokubonelela ngokhuseleko oluhle lomatshini kunye nokukhusela iibhetri kuwo wonke umjikelo wobomi;

4. Ngokwentelekiso iindleko zempahla ekrwada eziphantsi aziyi kubeka uxinzelelo olukhulu kwiindleko zokudityaniswa kwenkqubo yamandla yokugqibela;

5. Ubuncinci bexabiso leyunithi elinokugcinwa lincinci, elinempembelelo ebalulekileyo ekunciphiseni iindleko zokuthengisa emva kokuthengisa.

 

Ubume bokwakheka kwemodyuli yebhetri

Ukwakhiwa kwemodyuli yebhetri ngokuqhelekileyo kubandakanya iseli yebhetri, inkqubo yokulawula ibhetri, ibhokisi yebhetri, isixhumi sebhetri kunye nezinye iindawo.Iseli yebhetri yeyona nto isisiseko yemodyuli yebhetri.Iqulunqwe ngeeyunithi ezininzi zebhetri, ngokuqhelekileyo ibhetri ye-lithium-ion, eneempawu zobuninzi bamandla aphezulu, izinga eliphantsi lokuzikhupha kunye nobomi benkonzo ende.

Inkqubo yolawulo lwebhetri ikhona ukuqinisekisa ukhuseleko, ukuthembeka kunye nobomi obude bebhetri.Imisebenzi yayo ephambili ibandakanya ukubeka iliso kwimeko yebhetri, ulawulo lobushushu bebhetri, ukuhlawula ngaphezulu kwebhetri / ukukhuselwa kokukhutshwa, njl.

Ibhokisi yebhetri liqokobhe langaphandle lemodyuli yebhetri, esetyenziselwa ukukhusela imodyuli yebhetri kwindawo yangaphandle.Ibhokisi yebhetri idla ngokwenziwa ngentsimbi okanye izinto zeplastiki, ezinokumelana nokugqwala, ukumelana nomlilo, ukumelana nokudubula kunye nezinye iimpawu.

Isidibanisi sebhetri licandelo elidibanisa iiseli ezininzi zebhetri ziphelele.Ngokuqhelekileyo yenziwe ngezinto zobhedu, kunye ne-conductivity enhle, ukuchasana nokugqoka kunye nokuxhatshazwa kwe-corrosion.

Iimpawu zemodyuli yebhetri

Ukuchasana kwangaphakathi kubhekiselele ekuchaseni okuhambayo ngoku ibhetri xa ibhetri isebenza, echaphazelekayo kwizinto ezifana nezixhobo zebhetri, inkqubo yokuvelisa kunye nesakhiwo sebhetri.Ikwahlulwe kwi-ohmic ukuchasana kwangaphakathi kunye nokuchasana kwe-polarization yangaphakathi.I-Ohmic ukuchasana kwangaphakathi iqulethwe ukuxhatshazwa koqhagamshelwano lwezixhobo ze-electrode, i-electrolytes, i-diaphragms kunye neendawo ezahlukeneyo;i-polarization ukumelana kwangaphakathi kubangelwa i-electrochemical polarization kunye ne-concentration difference polarization.

Amandla athile – amandla ebhetri ngeyunithi yomthamo okanye ubunzima.

Ukutshaja kunye nokukhupha ukusebenza kakuhle - umlinganiselo weqondo apho amandla ombane asetyenziswa yibhetri ngexesha lokutshaja aguqulwa abe amandla ekhemikhali enokuthi igcinwe yibhetri.

I-Voltage – umahluko onokubakho phakathi kwee-electrode ezilungileyo nezingalunganga zebhetri.

Umbane ovulekileyo wesekethe: amandla ombane ebhetri xa kungekho sekethi yangaphandle okanye umthwalo wangaphandle uqhagamshelwe.Umbane ovulekileyo wesekethe unobudlelwane obuthile kunye nomthamo oseleyo webhetri, ngoko ke amandla ombane ebhetri aqhele ukulinganiswa ukuqikelela umthamo webhetri.Umbane osebenzayo: Umahluko onokubakho phakathi kwee-electrode ezilungileyo kunye nezingalunganga zebhetri xa ibhetri ikwimo yokusebenza, oko kukuthi, xa kukho ukudlula ngoku kwisekethe.Ukukhutshwa kwe-voltage ye-cut-off: i-voltage efike emva kokuba ibhetri ihlawuliswe ngokupheleleyo kwaye ikhutshwe (ukuba ukukhutshwa kuyaqhubeka, kuya kukhutshwa ngokugqithiseleyo, okuya kulimaza ubomi kunye nokusebenza kwebhetri).I-voltage ye-Charge cut-off voltage: i-voltage xa ​​iguquka ngokuqhubekayo ngoku rhoqo kwi-voltage yokutshaja ngexesha lokutshaja.

Intlawulo kunye nesantya sokukhupha - khupha ibhetri ngokusisigxina kwi-1H, oko kukuthi, i-1C.Ukuba ibhetri ye-lithium ilinganiswe kwi-2Ah, i-1C yebhetri yi-2A kunye ne-3C yi-6A.

Uxhulumaniso oluhambelanayo - Umthamo weebhetri unokunyuswa ngokuzidibanisa ngokufanayo, kunye nomthamo = umthamo webhetri enye * inani loxhumo oluhambelanayo.Ngokomzekelo, imodyuli ye-Changan 3P4S, umthamo webhetri enye yi-50Ah, ngoko umthamo wemodyuli = 50 * 3 = 150Ah.

Uxhulumaniso lweSeries - I-voltage yeebhetri inokunyuswa ngokuzidibanisa kuthotho.Voltage = amandla ombane ebhetri enye * inani leentambo.Ngokomzekelo, imodyuli ye-Changan 3P4S, i-voltage yebhetri enye yi-3.82V, ngoko i-module voltage = 3.82 * 4 = 15.28V.

 

Njengenxalenye ebalulekileyo kwizithuthi zombane, iimodyuli zebhetri ze-lithium zamandla zidlala indima ephambili ekugcineni nokukhulula amandla ombane, ukubonelela ngamandla, nokulawula nokukhusela iipakethi zebhetri.Zinentlukwano ethile ekubunjweni, umsebenzi, iimpawu kunye nesicelo, kodwa zonke zinempembelelo ebalulekileyo ekusebenzeni kunye nokuthembeka kwezithuthi zombane.Ngokuqhubela phambili okuqhubekayo kwethekhnoloji kunye nokwandiswa kwezicelo, iimodyuli zebhetri ze-lithium zamandla ziya kuqhubeka nokuphuhlisa kwaye zenze igalelo elikhulu ekukhuthazeni nasekudumeni izithuthi zombane.
