Izinhlobo zebhethri - yini umehluko?

Akumangalisi ukuthi amakhasimende avame ukuba nenkinga yokukhetha idivayisi efanelekile ngezidingo zabo. Ngakho-ke, sethula umhlahlandlela omfushane emhlabeni wamabhethri.

Ukuhlukaniswa kwebhethri nesevisi:

• Isevisi: amabhethri ajwayelekile adinga ukulawula nokugcwalisa izinga le-electrolyte ngokungeza amanzi acwecwe, isb. amabhethri e-acid eholayo.
• Usekelo lwamahhala: azidingi ukulawulwa nokugcwaliswa kabusha kwe-electrolyte, ngenxa yokusebenzisa lokho okubizwa ngokuthi. ukuhlangana kabusha kwangaphakathi kwamagesi (i-oksijeni ne-hydrogen kwakheka ngesikhathi sokujiya kokusabela futhi kuhlale kubhethri kusesimweni samanzi). Lokhu kufaka amabhethri e-VRLA lead acid (AGM, GEL, DEEP CYCLE) namabhethri e-LifePo.

Izinhlobo zebhethri esigabeni se-VRLA (I-Valve Regulated lead Acid):

• I-AGM - uchungechunge AGM, VPRO, OPTI (VOLT Poland)
• DEEP CYCLE - uchungechunge DEEP CYCLE VPRO SOLAR VRLA (OWAYENGUMLANDELI WASEPoland)
• I-GEL (ijeli) — Uchungechunge lwe-GEL VPRO PREMIUM VRLA (VOLT Polska)

Izinzuzo ezibaluleke kakhulu zamabhethri e-VRLA ngaphezu kwamabhethri okunakekela i-asidi eholayo ahlanganisa:

• Ukusekela Kwamahhala - sebenzisa ukusabela kwamakhemikhali lapho umoya-mpilo ne-hydrogen, okwakhiwa lapho ibhethri lishajwa kabusha, kuhlala kusesimweni samanzi. Lokhu kuqeda isidingo sokuhlola nokugcwalisa i-electrolyte kudivayisi, njengoba kwenzeka ngokulungiswa kwebhethri le-lead-acid yakudala.
• Ukuqina - ube ne-valve yendlela eyodwa ezivalayo evulekayo lapho ingcindezi ngaphakathi kwe-accumulator ikhuphuka futhi ikhiphe amagesi ngaphandle, ivikele isiqukathi ekuqhumeni. Ngenxa yalokho, amabhethri aphephile ukusetshenziswa futhi anobungani bemvelo. Azidingi amakamelo ane-ventilation ekhethekile, njengamabhethri okulungisa ajwayelekile. Bangakwazi ukusebenza kunoma yisiphi isikhundla (isibonelo, ohlangothini).
• Impilo yenkonzo ende - ekusebenzeni kwe-buffer, banempilo ende yesevisi (iminyaka eminingana).
• Imijikelezo eminingi - ngesikhathi sokusebenza kwe-cyclic bahlukaniswa nenani elikhulu lemijikelezo (ukushaja-ukukhishwa).
• Ubukhulu obubanzi - mancane kakhulu futhi acishe aphindwe kabili njengokukhanya njengamabhethri avamile anomthamo ofanayo.

Amabhethri e-AGM (ingilazi emuncwa) bane-glass mat fiber efakwe i-electrolyte, okwandisa ukusebenza kahle kwabo. Njengamabhethri e-VRLA, anenzuzo ngaphezu kwamabhethri e-lead-asidi evamile ukuze agcinwe, i.e. avaliwe, awadingi ukulawulwa kokwenza uketshezi, angasebenza ezindaweni ezihlukahlukene, aphephile emvelweni nasemvelweni, anempilo ende yesevisi nemijikelezo yomsebenzi, alula, amancane ngosayizi futhi kulula ukusebenza. Uma sikhuluma ngezinzuzo ngaphezu kozakwabo i-GEL (ijeli) noma i-DEEP CYCLE, lezi yizici ezinjengokuthi ashibhile, anempilo ende yesevisi kumodi ye-buffer (eqhubekayo), ukumelana okuphansi kwangaphakathi, futhi asebenza isikhathi eside ngaphansi kwemithwalo esindayo. Amabhethri e-AGM angasebenza kokubili kumodi yebhafa (ukusebenza okuqhubekayo) nakumodi ye-cyclic (ukuphuma njalo nokushajwa kabusha). Kodwa-ke, ngenxa yokuthi asebenza ngemijikelezo embalwa kunamabhethri e-GEL noma e-DEEP CYCLE, anconywa ukuthi asetshenziselwe ikakhulukazi umsebenzi webhafa. Ukusebenza kwe-buffer kusho ukuthi amabhethri e-AGM angasetshenziswa njengomthombo wamandla wesimo esiphuthumayo owengeziwe uma kwenzeka ukuphela kukagesi, njengokunqamuka kukagesi. ukunikezwa kwamandla okuphuthumayo kokufakwa kokushisisa okuphakathi, amaphampu, iziko, i-UPS, amarejista emali, amasistimu ama-alamu, izibani eziphuthumayo.

DEEP CYCLE ibhethri eyenziwe ngobuchwepheshe be-VRLA DEEP CYCLE. Njengamabhethri e-AGM, ane-electrolyte-impregnated glass fiber ukwandisa ukusebenza kahle kwawo. Ngaphezu kwalokho, impahla iqiniswa ngamapuleti okuhola. Njengomphumela, amabhethri e-DEEP CYCLE ahlinzeka ngokukhipha okujule kakhulu nemijikelezo eminingi kunamabhethri ajwayelekile e-AGM. Futhi zifaka ukumelana okuphansi kwangaphakathi kanye nezikhathi zokugijima ezinde ngaphansi kwemithwalo esindayo kunamabhethri ejeli (GEL). Abiza kakhulu kune-AGM ejwayelekile, kodwa ashibhile kunejeli (GEL). DEEP CYCLE amabhethri angasebenza kokubili kumodi yebhafa (ukusebenza okuqhubekayo) nakumodi ye-cyclic (ukuphuma njalo nokushajwa). Kusho ukuthini? Imodi yesibhafa ukuthi ibhethri lisebenza njengomthombo wamandla owengeziwe wezimo eziphuthumayo uma kwenzeka ukuphela kukagesi (ngokwesibonelo, ugesi ophuthumayo wokufakwa kokushisisa okuphakathi, amaphampu, iziko, i-UPS, amarejista emali, amasistimu e-alamu, ukukhanyisa kwesimo esiphuthumayo) . Ukusebenza komjikelezo, kulele eqinisweni lokuthi ibhethri isetshenziswa njengomthombo ozimele wamandla (isibonelo, ukufakwa kwe-photovoltaic).

Amabhethri ejeli (GEL) ube ne-electrolyte ngendlela yejeli ewugqinsi eyakhiwe ngemva kokuxuba i-sulfuric acid nezitsha ezikhethekile ze-ceramic. Ngesikhathi sokushaja kokuqala, i-electrolyte iphenduka ijeli, bese igcwalisa zonke izikhala kusihlukanisi sesipontshi se-silicate. Ngenxa yale nqubo, i-electrolyte igcwalisa ngokuphelele indawo etholakalayo ebhethri, okwandisa kakhulu ukumelana nokushaqeka kwayo futhi ivumela ukukhishwa okujulile ngaphandle komthelela omkhulu kumthamo webhethri. Asikho futhi isidingo sokuthi ngezikhathi ezithile ugcwalise futhi uhlole isimo sayo, ngoba i-electrolyte ayihwamuki noma ichithe. Uma kuqhathaniswa namabhethri e-AGM, amabhethri ejeli (GEL) abonakala ngokuyinhloko ngalezi:

• umthamo ophezulu wamandla aqhubekayo
• imijikelezo eminingi ngaphandle komthelela obalulekile kumthamo webhethri
• ukulahlekelwa okuphansi kakhulu kwenkokhiso (ukuzikhulula) ngesikhathi sokugcina kufika ezinyangeni eziyisi-6
• kungenzeka ukukhishwa okujulile kakhulu ngokulungiswa okulungile kwemingcele yokusebenza
• ukumelana nomthelela omkhulu
• ukumelana okukhulu namazinga okushisa aphansi kakhulu noma aphezulu kakhulu ngesikhathi sokusebenza

Ngenxa yemingcele emithathu yokumelana okuphezulu nezimo zokushisa, ukushaqeka nokuhamba ngebhayisikili, amabhethri e-GEL (gel) alungele ukufakwa kwe-photovoltaic noma, isibonelo, ukunikezwa kokukhanyisa okuzenzakalelayo. Kodwa-ke, abiza kakhulu kunamabhethri ajwayelekile angaseviswa noma angalungiseki: AGM, DEEP CYCLE.

Amabhethri e-serial I-LiFePO4

Amabhethri e-LiFePO4 (i-lithium iron phosphate) ane-BMS edidiyelwe abonakala ngokuyinhloko ngesisindo sawo esiphansi kakhulu nempilo yawo yomjikelezo ophezulu (cishe imijikelezo engu-2000 ku-100% DOD kanye nemijikelezo engu-3000 ku-80% DOD). Amandla okusebenza ngenani elikhulu lemijikelezo yokukhipha kanye nokushaja lenza lolu hlobo lwebhethri lube ngcono kakhulu kune-AGM evamile noma amabhethri e-GEL kumasistimu wamabhayisikili. Isisindo esiphansi sebhethri siyenza ilungele izindawo lapho kubalwa khona ikhilogremu ngayinye (isb. abakhempa, amaloli okudla, izakhiwo zezikebhe, izindlu zamanzi). Ukuzikhipha okuphansi kakhulu nekhono lokuzikhipha ngokujulile kwenza amabhethri e-LiFePO4 abe yisinqumo esihle kakhulu samandla aphuthumayo kanye nezinhlelo zokugcina amandla. Isistimu ye-BMS eyakhelwe ngaphakathi iqinisekisa ukugcinwa kwamabhethri ngaphandle kokulahlekelwa amandla okuzisholo isikhathi eside futhi ilawula izinqubo zokushaja nokukhipha amabhethri. Ibhethri ye-LiFePO4 inganika amandla amasistimu kagesi ezimo eziphuthumayo, ukufakwa kwe-photovoltaic ngaphandle kwegridi kanye nokugcinwa kwamandla.
