Uhlelo lokugcina amandla elanga le-photovoltaic luyisistimu yokugcina amandla esetshenziswa kakhulu emakethe. Amaphakethe ebhethri e-lithium ayizingxenye ezibalulekile ezinhlelweni zokugcina amandla e-off-grid photovoltaic. Ngakho-ke ungafanisa kanjani iphakethe lebhethri le-lithium?

12V uhlelo

Okwamanje, I-voltage yezinhlelo eziningi zokugcina amandla e-photovoltaic ingu-12V, ikakhulukazi off-grid amandla elanga izinhlelo, njengezibani zasemgwaqweni zelanga, imishini yokuqapha ilanga, izinto ezincane eziphathwayo zokugcina amandla e-photovoltaic, njalo njalo. Iningi lamasistimu okugcina amandla e-solar photovoltaic esebenzisa uchungechunge lwe-12V amasistimu okugcina amandla anamandla angaphansi kuka-300W.aic iziteshi zamandla okugcina amandla.

3Isistimu ye-V/6V/9V

Amanye amasistimu okugcina amandla e-photovoltaic aphansi-voltage ahlanganisa: 3V uchungechunge, njengezibani eziphuthumayo zelanga, izibani zodonga ezincane zelanga, njll.; 6V uchungechunge, njengezibani zotshani belanga, izimpawu zelanga, njll.; 9V uchungechunge lwezinhlelo zokugcina amandla e-photovoltaic nazo ziningi, Phakathi kwe-6V kanye ne-12V, amanye amalambu e-solar street nawo ane-9V. Amasistimu we-solar photovoltaic esebenzisa i-9V, 6V, kanye nochungechunge lwe-3V ngokuyisisekelo amasistimu amancane okugcina amandla angaphansi kuka-30W.

24V uhlelo

Ezinye izinhlelo zokugcina amandla ze-photovoltaic eziphezulu ze-voltage zihlanganisa: 24V uchungechunge, ezifana nenkundla yebhola ukukhanya kwelanga, usayizi ophakathi nendawo we-solar photovoltaic ephathekayo yokugcina amandla amasistimu, amandla alezi zinhlelo zokugcina amandla makhulu uma kuqhathaniswa, cishe 500W; kukhona 36V, 48V uchungechunge lwamasistimu okugcina amandla e-Photovoltaic, amandla ayoba makhulu, ngokuyisisekelo ngaphezu kuka-1000W, njengezinhlelo zokugcina amandla e-photovoltaic zasekhaya, amandla okugcina amandla angaphandle aphathekayo, njll., amandla azofinyelela cishe ku-5000W; kunjalo, kunezinhlelo ezinkulu zokugcina amandla e-photovoltaic, I-voltage izofinyelela ku-96V, 192V uchungechunge, lezi zinhlelo zokugcina amandla kagesi we-photovoltaic eziphezulu ikakhulukazi ziyiziteshi zamandla okugcina amandla e-photovoltaic ezinkulu..

Ngokuyisisekelo, ukubala kucatshangelwa ezicini ezimbili, esinye isikhathi sokunikezwa kwamandla kwesistimu yokugcina amandla; enye yisikhathi sokukhanya kwelanga kusuka kuphaneli yelanga nokushaja.

1- Cabangela isikhathi sokunikezwa kwamandla ukuze unqume umthamo wephakethe lebhethri le-lithium

Ngokwesibonelo, uchungechunge lwe-12V lwesistimu yokugcina amandla e-photovoltaic namandla angu-30W ukukhanya komgwaqo welanga okudingayo 10 amahora okukhanyisa nsuku zonke, futhi kuyadingeka ukucabangela isimo sokuthi angeke akhokhiswe ngezinsuku ezintathu zemvula.

Khona-ke umthamo wephakethe lebhethri le-lithium obaliwe ungaba ngu-30W*10h* izinsuku ezi-3/12V=75Ah. Singakwazi ukufanisa iphakethe lebhethri le-lithium le-12V75Ah ukuze sisekele le sistimu yokugcina amandla e-photovoltaic. Ifomula yokubala ithi:

Amandla okusebenzisa amanzi × isikhathi sokusebenza ÷ i-voltage yokusebenza = umthamo odingwa ibhethri

Nokho, ngezinsuku ezinamafu nezina, ngoba ayikwazi ukukhokhiswa, kuyadingeka ukuthi kucatshangelwe ukwandisa umthamo oyisipele ohambisanayo.

No.2 Kucatshangelwa iphaneli yelanga kanye nokushaja isikhathi sokukhanya kwelanga ukuze kunqunywe umthamo wephakethe lebhethri le-lithium

Ngokwesibonelo, ngochungechunge lwe-12V lwesistimu yokugcina amandla we-photovoltaic, amandla okukhipha wephaneli yelanga ngu-100W, futhi isikhathi esisebenzayo sokukhanya kwelanga sokushaja si 5 amahora ngosuku. Isistimu yokugcina amandla idinga ukushaja ngokugcwele ibhethri ye-lithium phakathi nosuku olulodwa. Indlela yokufanisa umthamo wephakethe lebhethri le-lithium?

Indlela yokubala ithi 100W*5h/12V=41.7Ah. Ngamanye amazwi, kulesi simiso se-photovoltaic sokugcina amandla, sidinga okungenani iphakethe lebhethri le-lithium elinomthamo we-12V41.7Ah ukuze sigcine ngokugcwele amandla aguqulelwe iphaneli yelanga ngesikhathi sokukhanya kwelanga.

Kunjalo, kubaluleke kakhulu ukuthi asikwazi ukukuziba ukuthi ifomula engenhla isebenza kuphela lapho kungekho ukulahlekelwa esimweni esiphelele. Ekusetshenzisweni kwangempela, uhlelo lwethu lwesifunda luzoba namazinga ahlukene okulahlekelwa. Uma ubala, izinga lokulahlekelwa lidinga ukucatshangelwa.

Elinye iphuzu okufanele liphawulwe ukuthi izinhlobo ezahlukene zamaphakethe ebhethri ye-lithium zinama-voltage ahlukene epulatifomu ebaliwe. Ngokwesibonelo, uma iphakethe lebhethri le-12V le-lithium lisebenzisa amabhethri e-ternary lithium, 3 amabhethri ayadingeka ochungechungeni, futhi i-voltage yesikhulumi izoba ngu-3.6V*3 String = 10.8V; kanye nephakethe lebhethri le-lithium iron phosphate lizosetshenziswa 4 uchungechunge ochungechungeni, khona-ke ipulatifomu kagesi izoba ngu-3.2V*4=12.8V.

Ngakho-ke, indlela yokubala enembe kakhudlwana kufanele icabangele ukulahlekelwa kwesistimu komkhiqizo othile kanye nevolthemu yesikhulumi ehambisanayo okufanele ibalwe, okuzobe kunembe kakhudlwana.

Uma unemibuzo, wamukelekile ukusishiya amazwana ngezansi noma Xhumana nathi khona manje.
