Ukuqonda izisekelo zebhethri kWh
I-Battery Kilowatt-Hour (KWH) isilinganiso esibalulekile esisetshenziselwa ukuhlola amandla nokusebenza kahle kweIzinhlelo Zokugcina Amandla. Ukubala ngokunembile i-Battery KWH kusiza ekuhloleni ukuthi malini ibhethri elingakugcina noma ukuletha, okwenza kube yipharamitha ebalulekile yezicelo ezahlukahlukene ezifana nezinhlelo zamandla avuselelekayo, izimoto zikagesi, nezinye izimoto eziphathwayo.
Yini ihora le-Kilowatt (KWH)?
I-Kilowatt-Hour (KWH) iyunithi lamandla athola ukusetshenziswa kwe-Energy okuphelele noma ukukhiqizwa ngaphezulu kwesikhathi esithile. I-KWH eyodwa ilingana namandla asetshenziswayo noma akhiqizwa lapho amandla e-Kilowatt (1,000 Watts) esetshenziswa ngehora elilodwa. Ngamafuphi, kuyisilinganiso esidonsa amandla nesikhathi lapho la mandla asekelwa khona.
Ngokwesibonelo:
I-1,000-watt Appliance egijima ihora eli-1 lisebenzisa 1 kWh.
Ukusebenza kwedivaysi engu-500-watt amahora angama-2 kuzosebenzisa futhi i-1 kWh (500w × 2h = 1,000h noma 1 kWh).
Lo mqondo ubalulekile ekuqondeni umthamo webhethri, ukuphathwa kwamandla, kanye nokusebenza kohlelo.
Ukubaluleka kwebhethri kwh
I-Battery KWH iyi-metric ebalulekile yokuthola amandla okugcina kanye nokusebenza kwamandla kwamabhethri. Kuthinta ngqo ukuthi ibhethri lingahambisa isikhathi esingakanani amandla namandla aphelele angawagcina. Ukuqonda okuphelele kwe-kWh kubalulekile ekuhlolweni kwamabhethri emikhakheni ehlukahlukene, kufaka phakathi izixazululo zamandla avuselelekayo,Izimoto zikagesi (EVS), nezinhlelo zamandla okusekelayo.
Kuchazwe amandla webhethri
Umthamo webhethri ubhekisele enanini lamandla ibhethri elingabamba, ngokujwayelekile elinganiselwa kuma-ampere-amahora (ah) noma amahora watt-(WH). Kubonisa ukuthi ibhethri lingaletha kangakanani isikhathi esibekiwe, ngaleyo ndlela lithonye ukusebenza kwebhethri, isikhathi sokuphila, kanye nokufaneleka kwezicelo ezithile.
· Ampere-amahora (ah): ulinganisa umthamo webhethri ngokuya kwamanje ngesikhathi sesikhathi (isib. Ibhethri le-100 AH linganikeza ama-Amps ayi-100 noma ama-Amps ayi-10).
· Amahora we-Watt (WH): Izinyathelo zamandla wamandla ngokubheka zombili lezi zinto zamanje nezomthamo (wh = ah × voltage).
Izici ezithonya umthamo webhethri
Umthamo webhethri akuyona inani elihleliwe futhi angahluka ngenxa yezici ezithobekile eziningana:
1.
2. Okwamanje (a): Umdwebo wamanje uthinta ukuthi ibhethri liphela ngokushesha kangakanani.
3. Ukusebenza kahle: Ukumelana kwangaphakathi nokunye ukulahleka kunganciphisa umthamo wangempela uma kuqhathaniswa namanani wethiyori.
I-4.Temperature: Amazinga okushisa aphezulu futhi aphansi anomthelela ekwakhekeni kwamakhemikhali ngaphakathi kwebhethri, eguqula umthamo wawo osebenzayo.
I-5.Battery Age: Amabhethri amadala ngokuvamile anciphise umthamo ngenxa yokonakala ngokuhamba kwesikhathi.
Izilinganiso zokubala ibhethri kWh
Ifomula eyisisekelo ukubala amandla agcinwe noma asetshenziswa ibhethri emalowatt-amahora yile:
I-KWH = Voltage (v) × manje (a) × isikhathi (h) ÷ 1,000
Lapho:
· Voltage (v) yi-voltage yebhethri.
· Okwamanje (a) umthamo wamanje noma umthamo (ku-AH).
Isikhathi (h) isikhathi sokusetshenziswa kwamandla noma ukulethwa.
· 1,000Is esetshenziselwa ukuguqula amahora we-watt-amahora (WH) kuya kuma-Kilowatt-amahora (kWh).
Izibonelo ezingokoqobo zokubala kwebhethri kwh
Masisebenzise ifomula kwezinye izimo zangempela zomhlaba wonke:
Isibonelo 1:
· Voltage: 48V
· Okwamanje: 20a
Isikhathi: 2 amahora
Kusetshenziswa ifomula:
kWh = 48V × 20I × 2h ÷ 1,000 = 1.92kWh
Lesi sibalo sibonisa ukuthi uhlelo lwe-48V oluhlinzeka nge-20a amahora amabili luzogcina noma lisebenzise i-1.92 kWh.
Izinhlobo zamabhethri kanye nokubalwa kwawo kwh
Izinhlobo ezahlukahlukene zebhethri zidinga ukuhlukahluka okuncane ekubaleni kwe-KWH ngokuya ngezimpawu zabo kanye nezimo zokusebenzisa.
Amabhethri e-lead-acid
Amabhethri e-lead-acid, asetshenziswe ezimotweni futhiIzinhlelo zamandla ezi-Backup, imvamisa inefomula elandelayo ye-kWh:
kWh = amandla we-voltage × (ku-ah)
Isibonelo, ibhethri le-12V le-Holid-acid elinomthamo we-100 ah lalizoba:
kWh = 12v × 100.200Wh ÷ 1,000 = 1.2KWH
Kubalulekile ukubheka ukusebenza kwebhethri nokujula kokukhululwa (DOD) lapho kubalwa i-kWh esebenzayo.
Amabhethri e-Lithium-ion
Amabhethri e-Lithium-ion, asetshenziswa kabanzi ezimotweni zikagesi kanye nama-elekthronikhi aphathekayo, sebenzisa ifomula efanayo eyisisekelo kepha evame ukuba nezimpawu ezihlukile zokusebenza kahle uma kuqhathaniswa namabhethri e-lead-acid:
kWh = amandla we-voltage × (ku-ah)
Isibonelo, i-3.7V, 2,500MAH (2.5Ah) Ibhethri le-lithium-ion lingaba nalo:
kWh = 3.7V × 2.5h = 9.25WH ÷ 1,000 = 0.00925kkwh
Izici okufanele zicatshangelwe ukubalwa kwebhethri kwh
Imiphumela engu-1.Temperature
Ukushisa okwedlulele kungathinta kakhulu ukusebenza kwebhethri. Amazinga okushisa aphezulu angasheshisa ukusabela kwamakhemikhali, ngenkathi amazinga okushisa aphansi ehlisa umoya, ukunciphisa amandla asebenzayo. Ukuhluka kokushisa kokushisa kubalulekile ekulinganiseni okunembile kwh.
2.Depth of Depection (DOD)
I-DoD ilinganisa iphesenti lomthamo ophelele webhethri osetshenzisiwe. Ukukhishwa okujulile kunciphisa isikhathi sokuphila kwebhethri, ngakho-ke ukubalwa kwe-kWh kufanele kulinganise ukukhishwa kwamandla nempilo yebhethri.
Ukusebenza kahle kwe-3.battery
Amabhethri awasebenzi nge-100%; Amanye amandla alahlekile ngenxa yokumelana kwangaphakathi nokungasebenzi kahle kwamakhemikhali. Kubandakanya isici esisebenza kahle (isib. Ukusebenza kahle kwe-90%) ekubaleni kuhlinzeka ngenani elinengqondo le-kWh.
Amathiphu Wokubalwa Kwebhethri Kwh
Amasistimu wokuqapha
Izinhlelo zokuphatha ibhethri ezithuthukile (BMS) noma amathuluzi wokuqapha anganikeza idatha yesikhathi sangempela kumandla kagesi, wamanje, kanye nokushisa. Lezi zinhlelo zithuthukisa ukunemba kokubala kwe-KWH nosizo ekubhekeni impilo yebhethri.
Ukulungiswa kwe-2.Regular
Ukuhlolwa okujwayelekile nokulungiswa, okubandakanya ukuhlolwa kokusebenza, qinisekisa ukuthi amabhethri asebenza ngaphakathi kwezimo ezifanele, enikeza ukufundwa kwe-kWh okungaguquki futhi okunembile ngokuhamba kwesikhathi.
IZINSELELE NEZixazululo Ezijwayelekile
1.Voltage kanye nokwehluka kwamanje
Ukushintshashintsha kwe-voltage kanye namanje kungaphazamisa izibalo ze-kWh. Kusetshenziswa ama-voltage Regulators kanye nama-Standilivilizer asiza ngokubushelela lokhu kuhlukahluka kwezilinganiso ezinengqondo zamandla.
2. Ukuhlaba amabhethri
Njengamabhethri aneminyaka yobudala, amandla abo ehluleka, eguqula i-kWh ephumelelayo. Kubandakanya isici sokucekelwa phansi ekubaleni kungasiza ukulindela izinguquko ngokuhamba kwesikhathi.
Izicelo zolwazi lwebhethri kwh
Izinhlelo ze-1.RenuseAble Energy
Ukuqonda i-Battery KWH kubalulekile ukuklama kahleIzinhlelo Zokugcina Amandlakumandla avuselelekayo amandla. Amanani anembile we-KWH asiza ukwandisa ukusetshenziswa kwamandla futhi aqinisekise ukunikezwa kwamandla ezinzile ngesikhathi sezizukulwane eziphansi.
2.Izimoto zikagesi (EVS)
I-Battery KWH iyinto ebaluleke kakhulu ekunqumeni uhla lwezimoto zikagesi. Abathengi bavame ukuhlola umthamo we-kWW wokuhlola ukusebenza kwe-EV kanye nokufaneleka kwezidingo zabo.
Ekuphetheni, ukubala i-Battery KWH kuyikhono elibalulekile lokuqonda ukugcinwa kwamandla, ukwenza kahle ukusebenza kohlelo, nokwenza izinqumo ezinolwazi ngokukhethwa kwebhethri nokusetshenziswa. Ngokucabanga ngezinto ezinjenge-voltage, umthamo, ukusebenza kahle, izimo zemvelo, abasebenzisi bangathola amanani we-KWH anembile ukukhulisa ukusetshenziswa kwebhethri kuzo zonke izinhlelo zokusebenza.
