Ukuqonda iziseko zebhetri kwh
Ibhetri ye-Kilowatt-iyure (kWh) inyathelo elibalulekileyo elisetyenziselwa ukuvavanya amandla kunye nokusebenza kwempumelelo kweIinkqubo zokuGcina amandla. Ngokuchanekileyo ukubala ibhetri kwh inceda ukuba ihlole amandla angaligcini ibhetri okanye ihambise, isenza iParameter ebalulekileyo kwizicelo ezihlaziyiweyo, iimoto zombane, kunye nezinye izinto zombane.
Yintoni i-kilowatt-yure (kWh)?
I-kilowatt-iyure (kWh) yiyunithi yamandla enza i-sumpotion iyonke yokusetyenziswa okanye ukuvelisa ngaphezulu kwexesha elithile. I-kwh ilingana namandla asetyenzisiweyo okanye oveliswe xa amandla e-kilowatt (i-1 000 yatts) ifakwe kwiyure enye. Eyona nto iphambili, ngumlinganiso othimba amandla kunye nexesha lokugcina la mandla.
Umzekelo:
Isixhobo se-1 000 se-Wattle-Watt esiqhuba iiyure ezili-1 sisebenzisa i-1 kWh.
Isixhobo esisebenzayo se-2 500 esisebenza iiyure ezi-2 siza kusebenzisa kwakhona i-1 kWh (500W × 2h = i-1,000Wh okanye i-1 kWh).
Le nto sisisiseko ekuqondeni umthamo webhetri, ulawulo lwamandla kunye nokusebenza kakuhle kwenkqubo.
Ukubaluleka kwebhetri kwh
Ibhetri kwh yimetriki ephambili yokumisela isikhundla sokugcina kunye nokusebenza kwamandla kwiibhetri. Ichaphazela ngokuthe ngqo ukuba ibhetri ingenisa amandla kunye namandla ewonke anokugcina. Ukuqonda okucokisekileyo kwe-kWh kubalulekile ekuvavanyeni iibhetri kumacandelo ngamacandelo, kubandakanya izisombululo zamandla ezihlaziyiweyo,Izithuthi zombane (i-EVs), kunye neenkqubo zamandla ezi-backup.
Umthamo webhetri ucacisiwe
Umthamo webhetri ubhekisa kwinani lamandla ibhetri enokubanjwa, iqhele ukulinganiswa kwiiyure ze-Amprere (Ah) okanye iiyure ze-Watt (wh). Ibonisa ukuba ibhetri ingakanani ibhetri enokuzisa ngaphezulu kwexesha elibekiweyo, ngaloo ndlela ikuphembelela intsebenzo yebhetri, ixesha lobomi, kunye nokufaneleka kwezicelo ezithile.
I-AHTERE-HAT (AH): Misela intlawulo yebhetri malunga nexesha langoku (umzekelo, ibhetri eyi-100 okanye i-10 yeeyure zeyure ezili-10).
Iiyure zomsebenzi (wh): Amanyathelo amandla amandla ngokujonga okwangoku kunye ne-voltage (wh = ah × × thamtage).
Izinto zokuphembelela ubungakanani bebhetri
Umthamo webhetri asiloxabiso elisisigxina kwaye ungahluka ngenxa yezinto ezininzi zokuphembelela:
I-1. I-Voltage (v): I-voltage ephezulu inyusa amandla e-PROPT.
2. Kungoku (a): Umzobo wangoku uchaphazela ukuba ibhetri iphelele kangakanani.
3. Ukusebenza kakuhle: Ukuxhathisa ngempumelelo kunye nezinye iilahleko kunokunciphisa isikhundla sokwenyani xa kuthelekiswa namaxabiso e-theoretical.
I-4mtemiepositurature: omabini amaqondo obushushu aphantsi kunye namazantsi anefuthe ukuphendula kwekhemikhali ngaphakathi kwebhetri, ukutshintsha amandla ayo okusebenzayo.
Iminyaka yobudala ye-5.Batshi: Iibhetri ezindala zihlala zinciphile ngenxa yokhukuliseko ekuhambeni kwexesha.
Iimpawu zokubala ibhetri kwh
Ifomula esisiseko yokubala amandla agcinwe okanye isetyenziswe ngebhetri kwi-kilowatt yeeyure:
kwh = ivolthi (v) × (a) × (i-H)
Phi:
I-probhyuli (v) yi-voltage yebhetri.
I-AHD (A) ngumthwalo okwangoku okanye umthamo (kwi-AH).
I-HATE (H) lithuba lokusebenzisa amandla okanye ukuhanjiswa.
I-· 100,000 isetyenziselwa ukuguqula iiyure ze-Watt (wh) ukuya kwii-Kilowatt-iiyure (kWh).
Imizekelo eSebenzayo yebhetri ye-KWH
Masisebenzise ifomula kwiziganeko ezithile zehlabathi zokwenyani:
Umzekelo 1:
I-prolotty: 48V
· 19: 20a
I-2 iiyure
Sebenzisa ifomula:
kwh = 48v × 20a × 2h ÷ i-1 000 = 1.92kwh
Oku kubalo kubonisa ukuba inkqubo ye-48V ibonelela nge-20a kwiiyure ezi-2 kwaye igcina okanye isebenzise i-1.92 kh yamandla.
Iindidi zeebhetri kunye nokubala kwabo
Iindidi ezahlukeneyo zebhetri zifuna ukwahluka okuncinci kwi-KWh ukubala esekwe kwiimpawu zazo kunye nemeko yokusetyenziswa kwazo.
Iibhetri ze-acid
Iibhetri ezikhokelayo, ezisetyenziswa kwizithuthi kwayeIinkqubo ze-Balls, ngokwesiqhelo banefomula ye-kWh elandelayo:
kwh = i-voltage ×
Umzekelo, ibhetri ye-12v-acid-I-ACID enesikhundla se-100 Ah inokuba:
kwh = 12v × 100,200wh ÷ I-1,000 = 1.2kwh
Kubalulekile ukuba kuqwalaselwe ukusebenza kwebhetri kunye nobunzulu bokukhupha (i-DOD) xa kubalwa i-kWh esebenzayo.
Ibhetri ye-lithium-ion
Ibhetri ye-lithium-ion, isetyenziswe ngokubanzi kwizithuthi zombane kunye ne-Engoma ephathwayo, sebenzisa ifomula esisiseko efanayo kodwa ihlala inempawu ezahlukeneyo zokusebenza xa kuthelekiswa neebhetri ze-Acid:
kwh = i-voltage ×
Umzekelo, i-3.7v, i-2,500mah (2.5ah) ibhetrium-ion iya kuba:
kwh = 3.7V × 2.5ah = 9.25Wh ÷ i-1 000) = 0.00925kwh
Izinto eziza kuqwalaselwa kwibhetri ye-kWh ukubala
I-1.1upitrouolos
Amaqondo obushushu agqithisileyo anokuba nefuthe elikhulu kakhulu kwibhetri. Amaqondo obushushu aphezulu anokukhawulezisa ukuphendula kweekhemikhali, ngelixa amaqondo obushushu asezantsi athotshiwe, ukunciphisa isikhundla esisebenzayo. Ukuveliswa kobushushu ohlukileyo kubalulekile kuqikelelo oluchanekileyo kwh.
2.Depth yokukhupha (i-DOD)
I-DOD ilinganisa ipesenti yomthamo opheleleyo webhetri osetyenzisiweyo. Ukucofa okunzulu kunciphisa ixesha lokuphila kwebhetri, ke ukubala kweKWh kufuneka ilungelelanise amandla okukhutshwa kwamandla kunye nezempilo yebhetri.
3.Mattery esebenzayo
Iibhetri azisebenzi nge-100%; Amanye amandla alahlekile ngenxa yokungaxhathisi sangaphakathi kunye nokungasebenzi kakuhle kwemichiza. Kubandakanywa nento esebenzayo (umz., 90% ukusebenza kakuhle) ekubaleni inika ixabiso le-KWH.
Iingcebiso zebhetri echanekileyo ye-KWH
I-1. I-1.I-1.Ukujonga iinkqubo zokujonga
Iinkqubo zolawulo lwebhetri phambili (ii-BMS) okanye izixhobo zokubeka iliso zinokubonelela ngedatha yexesha lokwenyani kwi-voltage, okwangoku, kunye neqondo lokushisa. Ezi nkqubo zikhuthaza ukuchaneka kwe-KWh ukubala kunye noncedo lokubeka esweni impilo yebhetri.
2. Ukulungiswa kwesondlo
Ukuhlolwa kwesiqhelo kunye nokulungiswa, kubandakanya uvavanyo lwentsebenzo, qinisekisa ukuba iibhetri zisebenza ngaphakathi kweemeko ezifanelekileyo, zibonelela ngokufundwayo kwe-KWh ngokuhamba kwexesha.
Imiceli mngeni kunye nezisombululo
I-1.VlilTAge kunye nokuQala okwangoku
Ukuguquguquka kwi-voltage kwaye okwangoku kunokubala ukubala kubala. Ukusebenzisa ii-voltage oomatshini kunye nokuzinzisa kunceda ukuthoba ezi zinto ziyahluka kwimilinganiselo echanekileyo yamandla.
2. Ukubhalwa
Njengeebhetri, amathayitha abo akhupha, ukutshintsha i-kWh asebenzayo. Kubandakanywa nento ekhathazayo enokubala inokunceda ekulindeleni utshintsho kwizikhundla ngokuhamba kwexesha.
Izicelo zolwazi lwe-KWH
Iinkqubo zamandla ezingenamali
Ukuqonda ibhetri kwh kubalulekile ukuba uyiloIinkqubo zokuGcina amandlakwizicwangciso zamandla ahlaziyiweyo. Iinqobo ezichanekileyo ze-kWh zinceda ekuphumezeni ukusetyenziswa kwamandla kwaye kuqinisekiswe ukuhanjiswa kwamandla kwizinto ngexesha lokuvelisa.
2.Izithuthi zombane (i-EVs)
Ibhetri kwh yinto ebaluleke kakhulu ekuqinisekiseni uluhlu lwezithuthi zombane. Abathengi bahlala bevavanya amandla e-KWH yokuvavanya ukusebenza kwe-Ev kunye nokufaneleka kweemfuno zabo.
Ukuqukumbela, ukubala ibhetri kwh sisakhono esibalulekileyo sokuqonda ukugcinwa kwamandla, ukwenza inkqubo yenkqubo, kunye nokwenza izigqibo ezinolwazi malunga nokukhetha ibhetri kunye nokusetyenziswa. Ngokuthatha izinto ezinjengevolthi, amandla, ukusebenza ngokukuko, kunye neemeko zokusingqongileyo, abasebenzisi banokufumana amaxabiso e-KWH echanekileyo yokwandisa isixhobo sebhetri kwizicelo ezahlukeneyo.
