Uma ufaka amandla elanga e-United States, ngokuvamile awudingi ukumisa ibhethri elihlukile, kodwa kunalokho uhambisana negridi. Ngenxa yokuthi igridi ilingana nokudlala indima yebhethri: emini, amandla elanga awakwazi ukusetshenziswa, azolethwa kugridi; ebusuku amandla elanga awakwazi ukukhiqiza ugesi, igridi yamandla. Unyaka olandelayo, izinhlangothi ezimbili ze-akhawunti iyonke: uma uhlelo lwakho lwamandla elanga lulethwa kugridi kagesi, ngaphezu kwekhaya lakho ngegridi kagesi, ibhalansi ithengiswa ngisho nakugridi. Kuphela, intengo yokuthenga kabusha kusuka kugridi iphansi kancane. Ngakolunye uhlangothi, uma usebenzisa ugesi omningi kusuka kugridi kunalokho uhlelo lwakho lwelanga olukulethela kugridi, kusadingeka uthenge umehluko kusuka kugridi ngentengo efanayo nangaphambili.
Udinga nini ukumisa ibhethri
1. Ugesi owengeziwe
Ukungazinzi kwegridi noma ukunqanyulwa kukagesi okuvamile:Uma igridi endaweni yakho ingazinzile noma kwenzeka ukunqamuka kwamandla njalo, ukucushwa kwebhethri kungaqinisekisa ukunikezwa kwamandla okuqhubekayo.
Amanani aphezulu kagesi ngesikhathi samahora okusetshenziswa kwegridi:Ukusebenzisa ugesi ogciniwe ngesikhathi samanani kagesi aphezulu kunganciphisa izindleko zikagesi.
Kulezi zimo ezimbili ezingenhla, uhlelo lwamandla elanga kusadingeka luhambisane negridi, isikhathi esikhethekile nje, kudingeka sisebenzise amandla ebhethri, ngakho-ke umthamo walo akudingeki ulungiselelwe kakhulu, ungasekela amahora angu-12.
2. Amandla azimele
Akukho uxhumano lwegridi (uhlelo olungaphandle kwegridi):Kwezinye izindawo ezikude ezingamboziwe yigridi, uhlelo lwelanga alunawo nhlobo ugridi (uhlelo olungaphandle kwegridi), ibhethri ngokusobala liyadingeka ukugcina ugesi okhiqizwa emini, ukuze lisetshenziswe ebusuku noma lapho kungekho ukukhanya okwanele.
Kulesi simo, uhlelo lwelanga alusebenzi ngokuphelele futhi ludinga ukuthembela ngokuphelele ebhethri ukuze luthole amandla ngesikhathi lapho uhlelo lwelanga lungakwazi ukukhiqiza amandla, ngakho-ke ukwakheka komthamo walo kudinga ukuba mkhulu ngokwanele ukusekela okungenani izinsuku ezingu-2-3.
Izidingo zemvelo zokugcina amabhethri:
Ukulawula izinga lokushisa:Amabhethri adinga ukugcinwa endaweni yokushisa ezinzile ukuze alondoloze ukusebenza kahle futhi andise isikhathi sokuphila kwenkonzo.
Umoya opholile:Ezinye izinhlobo zamabhethri zingase zikhiqize ukushisa noma amagesi ngesikhathi sokushaja nokukhipha, ngakho-ke kudingeka umoya omuhle.
Yomile futhi iphephile:Indawo yokugcina kufanele yome ukuze kugwenywe umonakalo womswakama ebhethri futhi kufanele ingafinyeleleki ezinganeni nasezifuyweni ukuze kugwenywe izingozi zokuphepha.
Ukufinyeleleka kalula:Ngezinjongo zokulungisa nokuhlola, ibhethri kufanele libekwe endaweni efinyeleleka kalula.
Umthamo wephaneli yelanga:Ukuze kube nohlelo olungaphandle kwegridi ngokuphelele, kudingeka umthamo owanele wamaphaneli elanga ukuze kukhiqizwe ugesi owanele, okuzokwandisa izindleko zokutshalwa kwezimali kokuqala.
Izindleko zokufaka:Izindleko zokufaka iphaneli yelanga kanye nohlelo lwebhethri nazo kudingeka zicatshangelwe.
Indawo kanye nezimo zelanga:Lokhu kuzothinta ukusebenza kahle kwamaphaneli elanga kanye nenani lamandla akhiqizwayo, okuzothinta iphaneli yelanga edingekayo kanye nomthamo webhethri.
Ukulinganiswa Kwezindleko Zebhethri
Izindleko zebhethri zincike kumthamo walo, uhlobo kanye nohlobo lokuxhumeka kwegridi. Ngaphezu kwezindleko zebhethri uqobo, izindleko zokufakwa kanye nokuhlanganiswa kwesistimu kudingeka zicatshangelwe.
Ake sithi umndeni osebenzisa ugesi waminyaka yonke ongu-10,000 kWh (ama-kilowatt-hours angu-10,000). Ukusetshenziswa kukagesi okujwayelekile kwansuku zonke kungaba cishe ngu-27.4 kWh (10,000 kWh / izinsuku ezingu-365).
Izindleko zeyunithi yebhethri zincike ohlotsheni lwayo kanye nohlobo lwayo. Isibonelo, amabhethri e-lithium-ion avame kakhulu emakethe namuhla abiza cishe u-$500 kuya ku-$1,000 nge-kWh.
Nazi izilinganiso ezihlukile
1. Izindleko zebhethri zokusetshenziswa kwamandla okwengeziwe
Izidingo zomthamo webhethri:Uma ibhethri lisetshenziswa kuphela ukubhekana nokuphazamiseka kukagesi kwesikhashana kanye namanani aphezulu kagesi, khona-ke akudingeki ukuthi limboze ngokugcwele ukusetshenziswa kukagesi okuvamile kwansuku zonke. Uma sicabanga ukuthi kudingeka amahora ayi-12 amandla okusekelayo, isidingo samandla ebhethri singaba ngu-13.7 kWh (27.4 kWh / 2).
Izindleko zebhethri:Izindleko eziphelele zebhethri le-lithium-ion, isibonelo, zisukela ku-$6,850 (500*13.7) kuya ku-$13,700 (1000*13.7).
2. Izindleko zebhethri le-lithium zikagesi ozimele
Amabhethri adinga ukuba namandla anele okwanelisa izidingo zikagesi izinsuku ezimbalwa, ikakhulukazi ezinsukwini ezinamafu noma zemvula eziqhubekayo. Uma sicabanga ukuthi kudingeka amandla okulinda izinsuku ezi-3, khona-ke kudingeka okungenani amandla ebhethri angu-82.2 kWh (27.4 kWh x izinsuku ezi-3).
Ngakho-ke izindleko zizonke ziphakathi kuka-$41,100 no-$82,200.
Ngokufigqiwe
Ukufaka ibhethri le-Lithium kuletha ukuguquguquka okwengeziwe kanye nokuzimela ohlelweni lwelanga, kodwa futhi nezindleko ezengeziwe kanye nezidingo zokulungisa.
Ukucatshangelwa kwesidingo samabhethri kufanele kusekelwe esidingweni sikagesi, isimo sezezimali, kanye nokunikezwa kukagesi endawo.
