Xa ufaka amandla elanga eMelika, awudingi ukumisela ibhetri eyahlukileyo, kodwa kufuneka ulungelelanise negridi. Ngenxa yokuba igridi ilingana nokudlala indima yebhetri: emini, amandla elanga awakwazi ukusetyenziswa, aya kuhanjiswa kwigridi; ebusuku amandla elanga awakwazi ukuvelisa umbane, igridi yamandla. Emva konyaka, amacala amabini e-akhawunti iyonke: ukuba inkqubo yakho yamandla elanga ihanjiswe kwigridi yombane, ngaphezu kwekhaya lakho ngegridi yombane, ibhalansi ithengiswa nakwigridi. Kuphela, ixabiso lokuthenga kwakhona kwigridi liphantsi kancinci. Kwelinye icala, ukuba usebenzisa umbane omninzi kwigridi kunokuba inkqubo yakho yelanga ihambisa kwigridi, kusafuneka uthenge umahluko kwigridi ngexabiso elifanayo nelangaphambili.
Ufanele uyilungiselele nini ibhetri
1. Umbane owongezelelweyo
Ukungazinzi kwegridi okanye ukucinywa kombane rhoqo:Ukuba igridi kwindawo okuyo ayizinzanga okanye umbane ucinywa rhoqo, ulwakhiwo lwebhetri lunokuqinisekisa ukunikezelwa kombane okuqhubekayo.
Amaxabiso aphezulu ombane ngexesha leeyure zokusetyenziswa kwegridi:Ukusebenzisa umbane ogciniweyo ngexesha lamaxabiso aphezulu ombane kunokunciphisa iindleko zombane.
Kwezi meko zimbini zingentla, inkqubo yamandla elanga kusafuneka ihambelane negridi, ixesha elikhethekileyo nje, kufuneka isebenzise amandla ebhetri, ngoko ke amandla ayo akufuneki acwangciswe kakhulu, anokuxhasa iiyure ezili-12.
2. Amandla azimeleyo
Akukho qhagamshelo lwegridi (inkqubo engekho kwigridi):Kwezinye iindawo ezikude ezingagutyungelwanga yigridi, inkqubo yelanga ayixhomekekanga ngokupheleleyo kwigridi (inkqubo engekho kwigridi), ibhetri ngokucacileyo iyimfuneko yokugcina umbane oveliswa emini, ukuze isetyenziswe ebusuku okanye xa kungekho kukhanya kwaneleyo.
Kule meko, inkqubo yelanga ayisebenzi ngokupheleleyo kwaye kufuneka ixhomekeke ngokupheleleyo kwibhetri ukuze ifumane amandla ngexesha leeyure apho inkqubo yelanga ingakwazi ukuvelisa amandla, ngoko ke ulwakhiwo lwamandla ayo kufuneka lube lukhulu ngokwaneleyo ukuxhasa ubuncinci iintsuku ezi-2-3.
Iimfuno zokusingqongileyo zokugcina iibhetri:
Ulawulo lobushushu:Iibhetri kufuneka zigcinwe kwindawo enobushushu obuzinzileyo ukuze zihlale zisebenza kakuhle kwaye zongeze ixesha lokusebenza.
Umoya ongenisayo:Ezinye iintlobo zeebhetri zinokuvelisa ubushushu okanye iigesi ngexesha lokutshaja nokukhupha itshaja, ngoko ke kufuneka umoya ococekileyo.
Yomile kwaye ikhuselekile:Indawo yokugcina kufuneka yome ukuze kuthintelwe ukonakala komswakama kwibhetri kwaye ingabi nakufikeleleka kubantwana nakwizilwanyana zasekhaya ukuze kuthintelwe iingozi zokhuseleko.
Ukufikeleleka lula:Ngeenjongo zokulungisa nokuhlola, ibhetri kufuneka ibekwe kwindawo efikeleleka lula.
Umthamo wephaneli yelanga:Kwinkqubo engasebenzi ngokupheleleyo kwigridi, kufuneka amandla aneleyo ephaneli yelanga ukuvelisa umbane owaneleyo, nto leyo eya kunyusa iindleko zotyalo-mali lokuqala.
Iindleko zokufakela:Kufuneka kuqwalaselwe neendleko zokufaka iphaneli yelanga kunye nenkqubo yebhetri.
Indawo kunye neemeko zelanga:Oku kuya kuchaphazela ukusebenza kakuhle kweephaneli zelanga kunye nobungakanani bamandla aveliswayo, nto leyo eya kuchaphazela iphaneli yelanga efunekayo kunye nomthamo webhetri.
Ukulinganiswa kweendleko zebhetri
Ixabiso lebhetri lixhomekeke kumthamo wayo, uhlobo kunye nohlobo loqhagamshelo lwegridi. Ukongeza kwixabiso lebhetri ngokwayo, iindleko zokufakela kunye nokudibanisa inkqubo kufuneka ziqwalaselwe.
Masithi usapho lusebenzisa umbane we-10,000 kWh (ii-kilowatt-iiyure ezili-10,000). Umbane osetyenziswayo ngemini uphakathi kwama-27.4 kWh (10,000 kWh / iintsuku ezingama-365).
Ixabiso leyunithi yebhetri lixhomekeke kuhlobo lwayo kunye nophawu lwayo. Umzekelo, iibhetri ze-lithium-ion eziqhelekileyo kwimarike namhlanje zixabisa malunga ne-$500 ukuya kwi-$1,000 nge-kWh nganye.
Nazi izilinganiso ezahlukeneyo
1. Ixabiso lebhetri lokusetyenziswa kwamandla ongezelelweyo
Iimfuno zomthamo webhetri:Ukuba ibhetri isetyenziselwa kuphela ukujongana nokucinywa kombane okwethutyana kunye namaxabiso aphezulu ombane, ngoko ke akufuneki ukuba igubungele ngokupheleleyo ukusetyenziswa kombane okuqhelekileyo kwemihla ngemihla. Ukuba kufuneka iiyure ezili-12 zamandla okuxhasa, imfuneko yomthamo webhetri imalunga ne-13.7 kWh (27.4 kWh / 2).
Ixabiso lebhetri:Ixabiso lilonke lebhetri ye-lithium-ion, umzekelo, liqala kwi-$6,850 (500*13.7) ukuya kwi-$13,700 (1000*13.7).
2. Iindleko zebhetri yeLithium yoMbane oZimeleyo
Iibhetri kufuneka zibe namandla aneleyo okwanelisa iimfuno zombane kangangeentsuku ezimbalwa, ingakumbi ngexesha leentsuku ezinamafu okanye ezinemvula rhoqo. Ukuba kufuneka amandla okulinda iintsuku ezi-3, kufuneka ubuncinane i-82.2 kWh (27.4 kWh x iintsuku ezi-3) yomthamo webhetri.
Ixabiso lilonke ke ngoko liphakathi kwe-$41,100 kunye ne-$82,200.
Isishwankathelo
Ukufaka ibhetri yeLithium kuzisa ukuguquguquka okungakumbi kunye nokuzimela kwinkqubo yelanga, kodwa kunye neendleko ezongezelelweyo kunye neemfuno zokugcinwa.
Ukuqwalaselwa kwesidingo seebhetri kufanele kusekelwe kwimfuno yombane, imeko yezemali, kunye nombane wasekuhlaleni.
