Ingabe Isistimu Yesitoreji Sebhethri Yasekhaya Iwufanele?Yiziphi Izici Ezincike Kuzo? Isitoreji sebhethri lendawo siyadingeka ukuze ikhaya elinamandla elanga liqhubeke lisebenza phakathi nokucisha kwegridi futhi ngokuqinisekile lizosebenza kusihlwa.Kodwa ngokufanayo, amabhethri elanga athuthukisa ezomnotho zesistimu yebhizinisi ngokugcina amandla kagesi elanga ngokuqinisekile ayengabuyiselwa kugridi ngokulahlekelwa, ukuze nje aphinde akhiphe lawo mandla kagesi ngezinye izikhathi lapho amandla ebiza kakhulu.Isitoreji sebhethri lasendlini sivikela umnikazi welanga ekuhlulekeni kwegridi futhi sivikela ezomnotho zesistimu ngokumelene nokuguqulwa kwezinhlaka zentengo yamandla. Ukuthi kufanelekile ukutshala imali noma cha kuncike ezintweni ezimbalwa: Izinga lezindleko zokutshala imali. Izindleko eziphansi nge-kilowatt-hora yomthamo, ngokushesha uhlelo lokugcina luzozikhokhela lona. Isikhathi sokuphila kweibhethri lasekhaya lelanga Iwaranti yomkhiqizi yeminyaka eyi-10 iyisiko embonini.Nokho, kucatshangelwa ukuphila okusebenzisekayo okude.Amabhethri asekhaya amaningi elanga anobuchwepheshe be-lithium-ion asebenza ngokuthembekile okungenani iminyaka engama-20. Isabelo sikagesi ozisebenzisela wona Ukugcinwa kwe-solar kakhudlwana kwandisa ukuzisebenzisela ngokwakho, maningi amathuba okuba kube nenzuzo. Izindleko zikagesi uma uthengwa kugridi Uma amanani kagesi ephakeme, abanikazi bezinhlelo ze-photovoltaic basindisa ngokudla ugesi owenziwe ngokwabo.Eminyakeni embalwa ezayo, amanani kagesi kulindeleke ukuthi aqhubeke nokukhuphuka, ngakho abaningi babheka amabhethri elanga njengotshalomali oluhlakaniphile. Izintengo ezixhunywe kwigridi Abanikazi besistimu yelanga abancane abathola i-kilowatt-hora, kubakhokhela kakhulu ukuthi bagcine ugesi esikhundleni sokuwufaka kugridi.Eminyakeni engama-20 edlule, amanani entengo axhunywe kwiGridi aye ehla kancane kancane futhi azoqhubeka nokwenza kanjalo. Yiziphi Izinhlobo Zezinhlelo Zesitoreji Samandla Ebhethri Lasekhaya Ezitholakalayo? Amasistimu okulondoloza ibhethri lasekhaya anikeza izinzuzo eziningi, okuhlanganisa ukuqina, ukonga izindleko kanye nokukhiqizwa kukagesi ohlukaniselwe izwe (owaziwa nangokuthi "amasistimu asakazwa ekhaya").Ngakho yiziphi izigaba zamabhethri asekhaya elanga?Kufanele sikhethe kanjani? Ukuhlelwa Okusebenzayo Ngomsebenzi Wokwenza Ikhophi Yasenqolobaneni: 1. I-Home UPS Power Supply Lena isevisi yezinga lezimboni yamandla ayisipele idinga ukuthi izibhedlela, amagumbi edatha, uhulumeni wobumbano noma izimakethe zempi ngokuvamile zidinga ukuze kuqhutshekwe nokusebenza kwamadivayisi azo abalulekile futhi azwelayo.Ngokunikezwa kwamandla e-UPS yendlu, izibani ezisendlini yakho zingase zingacwayizi uma igridi yamandla ihluleka.Amakhaya amaningi awadingi noma awahlosile ukukhokhela leli zinga lokwethenjelwa - ngaphandle uma esebenzisa imishini yokwelapha ebalulekile ekhaya lakho. 2. 'Interruptible' Power Supply (indlu egcwele isipele). Isinyathelo esilandelayo sokwehla ku-UPS yilokho esizokubiza ngokuthi 'ukunikezwa kwamandla okuphazamiseka', noma i-IPS.I-IPS ngokuqinisekile izovumela indlu yakho yonke ukuthi iqhubeke isebenza ku-solar namabhethri uma igridi yehla, kodwa ngokuqinisekile uzothola isikhathi esifushane (imizuzwana embalwa) lapho yonke into iba mnyama noma impunga endlini yakho njengohlelo lokulondoloza. ingena imishini.Ungase udinge ukusetha kabusha amawashi akho e-electronic acwayizayo, kodwa ngaphandle kwalokho uzokwazi ukusebenzisa zonke izinto zakho zikagesi zasendlini ngendlela obujwayele ukwenza ngayo uma nje amabhethri akho esekhona. 3. Ukunikezwa Amandla Kwesimo Esiphuthumayo (ingxenye yesipele). Okunye ukusebenza kwamandla okusekelayo kusebenza ngokuvula isekethe yesimo esiphuthumayo uma ithola ukuthi igridi yehlile ngempela.Lokhu kuzovumela imishini yamandla endlu exhunywe kule sekethi– ngokuvamile amafriji, amalambu kanye nezindawo zikagesi ezimbalwa ezizinikele– ukuthi ziqhubeke nokusebenza kwamabhethri kanye/noma amaphaneli e-photovoltaic ngesikhathi sokucisha.Lolu hlobo lwesipele cishe lungenye yezinketho ezidume kakhulu, ezinengqondo futhi ezivumelana nesabelomali emakhaya emhlabeni jikelele, njengoba ukusebenzisa indlu yonke ebhange lebhethri kuzowaqeda ngokushesha. 4. Ingxenye ye-off-grid Solar & Storage System. Inketho yokugcina engase ihehe 'isistimu ye-off-grid eyingxenye'.Ngengxenye yesistimu ye-off-grid, umqondo uwukukhiqiza indawo ezinikele 'engaphandle kwegridi' yekhaya, eqhubeka isebenza ngesistimu yelanga nebhethri enkulu ngokwanele ukuzinakekela ngaphandle kokudonsa amandla kugridi.Ngale ndlela, izinkatho zomndeni ezidingekayo (iziqandisi, izibani, njll) zihlala zivuliwe ngisho noma igridi yehla, ngaphandle kokuphazamiseka.Ukwengeza, njengoba i-solar namabhethri kulinganiswa ukuze azisebenze unomphela ngaphandle kwegridi, ngeke kube nesidingo sokwaba ukusetshenziswa kwamandla ngaphandle kwalapho amadivayisi engeziwe exhunywe kwisekethe engaphandle kwegridi. Ukwahlukaniswa kusuka kuBattery Chemistry Technology: Amabhethri e-lead-acid Njengesipele Sebhethri Lendawo yokuhlala Amabhethri e-lead-acidamabhethri amadala angaphinda ashajwe kanye nebhethri ebiza kancane etholakalayo yokugcina amandla emakethe.Bavela ekuqaleni kwekhulu leminyaka elidlule, ngawo-1900, futhi kuze kube yilolu suku bahlala bengamabhethri athandwayo ezinhlelweni eziningi ngenxa yokuqina kwabo kanye nezindleko eziphansi. Ukungalungi kwabo okuyinhloko ukuminyana kwamandla aphansi (ziyasinda futhi zikhulu) kanye nesikhathi sabo sokuphila esifushane, ukungamukeli inani elikhulu lemijikelezo yokulayisha nokulayisha, amabhethri e-lead-acid adinga ukunakekelwa okuvamile ukuze alinganise ikhemistri ebhethri, ngakho izici zayo. akwenze kungafaneleki ekukhishweni kwemvamisa emaphakathi kuya kwephezulu noma izicelo ezihlala iminyaka eyi-10 noma ngaphezulu. Futhi banobubi bokukhipha ukujula okuphansi, okuvamise ukukhawulelwa ku-80% ezimeni ezimbi kakhulu noma u-20% ekusebenzeni okuvamile, impilo ende.Ukuchichima ngokweqile kwehlisa isithunzi ama-electrode ebhethri, okunciphisa amandla ayo okugcina amandla futhi kukhawulele ukuphila kwayo. Amabhethri aneasidi yomthofu adinga ukunakekelwa okuqhubekayo kwesimo sawo sokushajwa futhi kufanele ngaso sonke isikhathi agcinwe esimeni sawo esiphezulu sokushajwa kusetshenziswa indlela yokuntanta (ukugcinwa kweshaji ngogesi omncane, owanele ukukhansela umphumela wokuzikhulula). Lawa mabhethri angatholakala ezinguqulweni ezimbalwa.Avame kakhulu amabhethri aphuma umoya, asebenzisa i-electrolyte ewuketshezi, amabhethri ejeli alawulwa yi-valve (VRLA) namabhethri ane-electrolyte ashumekwe kumata we-fiberglass (owaziwa ngokuthi i-AGM - ingilazi edonsayo), asebenza okumaphakathi nezindleko ezincishisiwe uma kuqhathaniswa namabhethri ejeli. Amabhethri alawulwa yi-valve avalwa ngokoqobo, okuvimbela ukuvuza nokomisa kwe-electrolyte.I-valve isebenza ekukhishweni kwamagesi ezimeni ezikhokhiswe kakhulu. Amanye amabhethri e-asidi yomthofu athuthukiswa ukuze asetshenziswe ezimbonini ezimile futhi angamukela imijikelezo yokukhipha ejulile.Kukhona nenguqulo yesimanjemanje, okuyibhethri le-lead-carbon.Izinto ezisekelwe kukhabhoni ezengezwe kuma-electrode zinikeza ukushaja okuphezulu nokukhipha imisinga, ukuminyana kwamandla aphezulu, nokuphila isikhathi eside. Enye inzuzo yamabhethri e-lead-acid (kunoma yikuphi ukuhluka kwawo) ukuthi awadingi uhlelo lokuphatha ukushaja oluyinkimbinkimbi (njengoba kunjalo ngamabhethri e-lithium, esizowabona ngokulandelayo).Amabhethri omthofu mancane kakhulu amathuba okuthi abambe umlilo futhi aqhume lapho eshajwe ngokweqile ngoba i-electrolyte yawo ayivuthi njengaleyo yamabhethri e-lithium. Futhi, ukushajwa ngokweqile okuncane akuyona ingozi kulezi zinhlobo zamabhethri.Ngisho nezinye izilawuli zokushaja zinomsebenzi wokulinganisa oshajwa kancane ibhethri noma ibhange lebhethri, okubangela ukuthi wonke amabhethri afinyelele esimweni sokushajwa ngokugcwele. Phakathi nenqubo yokulinganisa, amabhethri agcina eshajwe ngokugcwele ngaphambi kokuba amanye abe nogesi okhushulwe kancane, ngaphandle kwengozi, kuyilapho owamanje ugeleza ngokujwayelekile ngenhlangano ye-serial yezinto.Ngale ndlela, singasho ukuthi amabhethri omthofu anamandla okulinganisa ngokwemvelo kanye nokungalingani okuncane phakathi kwamabhethri ebhethri noma phakathi kwamabhethri ebhange anikezi ingozi. Ukusebenza:Ukusebenza kahle kwamabhethri e-lead-acid kuphansi kakhulu kunamabhethri e-lithium.Nakuba ukusebenza kahle kuncike esilinganisweni sokushaja, ukuhamba kahle kokuya nokubuya okungu-85% kuvame ukucatshangwa. Umthamo wesitoreji:Amabhethri ane-asidi yomthofu afika ebangeni lama-voltage nosayizi, kodwa anesisindo esiphindwe izikhathi ezingu-2-3 nge-kWh ngayinye kune-lithium iron phosphate, kuye ngekhwalithi yebhethri. Izindleko zebhethri:Amabhethri aneasidi yomthofu abiza kancane ngo-75% kunamabhethri e-lithium iron phosphate, kodwa ungakhohliswa inani eliphansi.Lawa mabhethri awakwazi ukushajwa noma ukushajwa ngokushesha, abe nempilo emfushane kakhulu, akanalo uhlelo lokulawula ibhethri elivikelayo, futhi angadinga ukunakekelwa kwamasonto onke.Lokhu kuphumela ezindlekweni eziphakeme zizonke ngomjikelezo ngamunye kunezinga elifanele lokunciphisa izindleko zamandla noma ukusekela izinto ezisebenza kanzima. Amabhethri e-Lithium Njengesipele Sebhethri Lendawo yokuhlala Njengamanje, amabhethri aphumelele kakhulu kwezentengiso amabhethri e-lithium-ion.Ngemuva kokuthi ubuchwepheshe be-lithium-ion busetshenziswe emishinini ye-elekthronikhi ephathekayo, ingene emikhakheni yezicelo zezimboni, izinhlelo zamandla, isitoreji samandla e-Photovoltaic kanye nezimoto zikagesi. Amabhethri e-Lithium-ionzidlula ezinye izinhlobo eziningi zamabhethri aphinde ashajwe ezicini eziningi, okuhlanganisa umthamo wokugcina amandla, inani lemijikelezo yomsebenzi, isivinini sokushaja, kanye nokusebenza kahle kwezindleko.Njengamanje, inkinga kuphela ukuphepha, ama-electrolyte avuthayo angabamba umlilo emazingeni okushisa aphezulu, okudinga ukusetshenziswa kokulawulwa kwe-elekthronikhi nokuqapha izinhlelo. I-Lithium iyinsimbi elula kunazo zonke, inamandla aphakeme kakhulu we-electrochemical, futhi inikeza ukuminyana okuphezulu kwevolumu namandla amakhulu kunobunye ubuchwepheshe bebhethri obaziwayo. Ubuchwepheshe be-lithium-ion buye benza kwaba nokwenzeka ukushayela ukusetshenziswa kwezinhlelo zokugcina amandla, ikakhulukazi ezihlotshaniswa nemithombo yamandla avuselelekayo ngezikhathi ezithile (ilanga nomoya), futhi uye waqhuba ukwamukelwa kwezimoto zikagesi. Amabhethri e-lithium-ion asetshenziswa ezinhlelweni zikagesi nasezimotweni zikagesi awuhlobo oluwuketshezi.Lawa mabhethri asebenzisa isakhiwo sendabuko sebhethri ye-electrochemical, enama-electrode amabili acwiliswe kusixazululo se-electrolyte ewuketshezi. Izihlukanisi (izinto zokuvikela ezinama-porous) zisetshenziselwa ukuhlukanisa ngomshini ama-electrode ngenkathi kuvumela ukunyakaza kwama-ion mahhala nge-electrolyte ewuketshezi. Isici esiyinhloko se-electrolyte ukuvumela ukuqhutshwa kwe-ionic current (eyakhiwe ama-ion, okungama-athomu anokweqile noma ukuntuleka kwama-electron), kuyilapho kungavumeli ama-electron ukuba adlule (njengoba kwenzeka ezintweni zokuqhuba).Ukushintshaniswa kwama-ion phakathi kwama-electrode amahle noma angalungile kuyisisekelo sokusebenza kwamabhethri e-electrochemical. Ucwaningo lwamabhethri e-lithium lungalandelelwa emuva kuma-1970s, futhi ubuchwepheshe buvuthwa futhi baqala ukusetshenziswa kwezohwebo eminyakeni yawo-1990. Amabhethri e-lithium polymer (anama-electrolyte e-polymer) manje asetshenziswa kumafoni ebhethri, amakhompiyutha kanye namadivayisi eselula ahlukahlukene, ashintsha amabhethri e-nickel-cadmium amadala, inkinga eyinhloko "umphumela wememori" onciphisa kancane kancane umthamo wokugcina.Uma ibhethri selishajwe ngaphambi kokuthi liphele. Uma kuqhathaniswa namabhethri amadala e-nickel-cadmium, ikakhulukazi amabhethri e-lead-acid, amabhethri e-lithium-ion anomthamo omkhulu wamandla (agcina amandla engeziwe ngevolumu ngayinye), ane-coefficient ephansi yokuzikhipha, futhi akwazi ukumelana nokushajwa okwengeziwe kanye nenani lemijikelezo yokukhipha , okusho impilo ende yesevisi. Ngasekuqaleni kwawo-2000, amabhethri e-lithium aqala ukusetshenziswa embonini yezimoto.Cishe ngo-2010, amabhethri e-lithium-ion athola isithakazelo ekugcinweni kwamandla kagesi ezindaweni zokuhlala kanyeizinhlelo ezinkulu ze-ESS (Energy Storage System)., ikakhulukazi ngenxa yokwanda kokusetshenziswa kwemithombo yamandla emhlabeni wonke.Amandla avuselelekayo ngezikhathi ezithile (ilanga nomoya). Amabhethri e-lithium-ion angaba nokusebenza okuhlukile, ubude bempilo, nezindleko, kuye ngokuthi enziwa kanjani.Kuye kwahlongozwa izinto eziningana, ikakhulukazi ama-electrode. Ngokuvamile, ibhethri le-lithium liqukethe i-electrode esekwe kwi-lithium eyinsimbi eyenza itheminali ephozithivu yebhethri kanye ne-carbon (graphite) electrode eyenza itheminali enegethivu. Ngokuya ngobuchwepheshe obusetshenzisiwe, ama-electrode asuselwa ku-lithium angaba nezakhiwo ezahlukahlukene.Izinto ezisetshenziswa kakhulu ekwenzeni amabhethri e-lithium nezici eziyinhloko zalawa mabhethri zimi kanje: I-Lithium ne-Cobalt Oxides (LCO):Amandla athile aphezulu (Wh/kg), umthamo omuhle wokugcina kanye nempilo eyanelisayo (inani lemijikelezo), ifaneleka kumadivayisi kagesi, ukungalungi amandla athile (W/kg) Amancane, anciphisa isivinini sokulayisha nokulayisha; I-Lithium neManganese Oxides (LMO):vumela ukushaja okuphezulu nokukhipha imisinga ngamandla athile aphansi (Wh/kg), okunciphisa umthamo wokugcina; I-Lithium, i-Nickel, iManganese ne-Cobalt (NMC):Ihlanganisa izakhiwo zebhethri ye-LCO ne-LMO.Ngaphezu kwalokho, ukuba khona kwe-nickel ekubunjweni kusiza ukwandisa amandla athile, ukunikeza umthamo omkhulu wokugcina.I-Nickel, i-manganese ne-cobalt ingasetshenziswa ngezilinganiso ezihlukene (ukusekela eyodwa noma enye) kuye ngohlobo lwesicelo.Sekukonke, umphumela wale nhlanganisela ibhethri elisebenza kahle, umthamo omuhle wokugcina, impilo ende, kanye nezindleko eziphansi.
