I-solar photovoltaic energy storage systems ifanelana kanjani namaphakethe ebhethri ye-lithium?

Uhlelo lokugcina amandla elanga le-photovoltaic luwuhlelo olusetshenziswa kakhulu lokugcina amandla emakethe. Kuzinhlelo zokugcina amandla e-off-grid photovoltaic, amaphakethe ebhethri e-lithium ayingxenye ebalulekile. Ngakho-ke ungafanisa kanjani iphakethe lebhethri le-lithium? Yabelana ngalokhu namuhla.

Isistimu yokugcina amandla elanga ye-photovoltaic-- ukukhanya komgwaqo welanga

1. Okokuqala, thola uchungechunge lweplathifomu ye-voltage yesistimu yokugcina amandla elanga ye-photovoltaic
   Njengamanje, amapulatifomu amaningi we-voltaic wesistimu yokugcina amandla e-photovoltaic anguchungechunge lwe-12V, ikakhulukazi amasistimu okugcina amandla e-off-grid, njengezibani zasemgwaqweni zelanga, izinhlelo zokuqapha amandla elanga lokugcina amandla, izinto ezincane eziphathekayo ze-photovoltaic zokugcina amandla okugcina amandla, njalonjalo. Iningi lamasistimu okugcina amandla elanga le-photovoltaic esebenzisa uchungechunge lwe-12V amasistimu okugcina amandla anamandla angaphansi kuka-300W.

Amanye amasistimu okugcina amandla e-photovoltaic aphansi-voltage ahlanganisa: uchungechunge lwe-3V, njengezibani eziphuthumayo zelanga, izimpawu ezincane zelanga, njll.; 6V uchungechunge, ezifana izibani solar utshani, izimpawu solar, njll.; I-9V yochungechunge lwezinhlelo zokugcina amandla e-photovoltaic nazo ziningi, phakathi kwe-6V ne-12V, ezinye izibani zasemgwaqweni zelanga nazo zine-9V. Amasistimu e-solar photovoltaic asebenzisa i-9V, 6V, kanye nochungechunge lwe-3V amasistimu amancane okugcina amandla angaphansi kuka-30W.

ukukhanya kwelanga lotshani

Ezinye izinhlelo zokugcina amandla ze-photovoltaic eziphezulu ze-voltage zihlanganisa: uchungechunge lwe-24V, njengokukhanya kwelanga lenkundla yebhola, amasistimu okugcina amandla aphathekayo we-solar photovoltaic ephathekayo, amandla alezi zinhlelo zokugcina amandla makhulu kakhulu, mayelana ne-500W; kukhona 36V, 48V uchungechunge Photovoltaic isitoreji energy izinhlelo, ukugcizelelwa kuyoba okubaluleke kakhulu. Ngaphezu kwe-1000W, njengezinhlelo zokugcina amandla e-photovoltaic zasekhaya, amandla okugcina amandla aphathekayo angaphandle, njll., amandla azofinyelela cishe ku-5000W; Yebo, kunezinhlelo ezinkulu zokugcina amandla e-photovoltaic, i-voltage izofinyelela ku-96V, uchungechunge lwe-192V, lezi zinhlelo zokugcina amandla ze-photovoltaic eziphezulu kakhulu ziyiziteshi zamandla zokugcina amandla e-photovoltaic ezinkulu.

2. Indlela yokufanisa yomthamo wephakethe lebhethri le-lithium
   Sithatha uchungechunge lwe-12V nenqwaba enkulu emakethe njengesibonelo emikhiqizweni yobuchwepheshe, sizokwabelana ngendlela efanayo yamaphakethe ebhethri ye-lithium.

Njengamanje, kunezici ezimbili ezihambisanayo; esinye isikhathi sokunikezwa kwamandla kwesistimu yokugcina amandla ukubala okufanayo; enye iphaneli yelanga kanye nesikhathi sokushaja sokukhanya kwelanga ukufanisa.

Ake sikhulume ngokufanisa umthamo wephakethe lebhethri le-lithium ngokwesikhathi sokuphakelwa kwamandla.

Isibonelo, uchungechunge lwe-12V isistimu yesitoreji samandla e-photovoltaic namandla angu-50W ukukhanya komgwaqo welanga kudinga ukuba namahora angu-10 okukhanya nsuku zonke. Kudingekile ukucabangela ukuthi Awukwazi ukukhokhisa ngezinsuku ezintathu zemvula.

Bese kubalwa umthamo wephakethe lebhethri le-lithium ungaba ngu-50W10hIzinsuku ezi-3/12V=125Ah. Singakwazi ukufanisa iphakethe lebhethri le-lithium le-12V125Ah ukuze sisekele le sistimu yokugcina amandla e-photovoltaic. Indlela yokubala ihlukanisa isamba senani lamahora wama-watt adingwa isibani somgwaqo ngevolthi yesikhulumi. Uma Ingakwazi ukushaja ngezinsuku ezinamafu nezimvula, kuyadingeka ukuthi ucabangele ukwandisa umthamo oyisipele ohambisanayo.

Ake sikhulume ngendlela yokufanisa umthamo wephakethe lebhethri ye-lithium ngokusho kwephaneli yelanga kanye nesikhathi sokushaja kwelanga.

Isibonelo, kusewuchungechunge lwe-12V yesistimu yokugcina amandla we-photovoltaic. Amandla okukhipha ephaneli yelanga angu-100W, futhi isikhathi esanele sokukhanya kwelanga sokushaja amahora angu-5 ngosuku. Isistimu yokugcina amandla idinga ukushaja ibhethri ye-lithium phakathi nosuku olulodwa ngokugcwele. Ungafanisa kanjani umthamo wephakethe lebhethri le-lithium?

Indlela yokubala ithi 100W*5h/12V=41.7Ah. Okusho ukuthi, kulolu hlelo lokugcina amandla we-photovoltaic, singakwazi ukufanisa iphakethe lebhethri ye-lithium engu-12V41.7Ah.

uhlelo lokugcina amandla elanga

Indlela yokubala engenhla ayikunaki ukulahlekelwa. Ingakwazi ukubala inqubo yokusetshenziswa yangempela ngokwezinga elithile lokuguqulwa kokulahlekelwa. Kukhona futhi izinhlobo ezahlukene zamaphakethe ebhethri ye-lithium, kanye ne-voltage yesikhulumi esihlanganisiwe nayo ihlukile. Isibonelo, iphakethe lebhethri le-lithium lesistimu engu-12V lisebenzisa ibhethri le-lithium le-ternary futhi lidinga ukuxhunywa kochungechunge oluthathu. I-voltage yesikhulumi izoba ngu-3.6V3 izintambo=10.8V; Iphakethe lebhethri le-lithium iron phosphate lizosebenzisa oku-4 ochungechungeni ukuze iplathifomu ye-voltage ibe ngu-3.2V4=12.8V.

Ngakho-ke, indlela yokubala enembe kakhudlwana idinga ukubalwa ngokwengeza ukulahlekelwa kwesistimu komkhiqizo othile kanye ne-voltage yeplathifomu ethize ehambisanayo, ezonemba kakhudlwana.

Isiteshi Samandla Esiphathekayo

I-Power Station Portable iyisisetshenziswa esiphathwayo, esisebenza ngebhethri esingaphakela ugesi emishinini eyahlukene kagesi. Ngokuvamile iqukethe ibhethri ne-inverter, eguqula amandla e-DC agciniwe abe amandla e-AC angasetshenziswa yizinto ezisetshenziswa kakhulu zasendlini nezinto zikagesi. Iziteshi zikagesi eziphathwayo zivame ukusetshenziswa njengomthombo wamandla oyisipele wokukhempa, imicimbi yangaphandle, nezimo eziphuthumayo.

Iziteshi zamandla aphathekayo zivame ukushajwa kusetshenziswa i-outlet yodonga noma iphaneli yelanga, futhi zingathwalwa kalula noma zihanjiswe ezindaweni ezihlukene. Atholakala ngebanga losayizi nokuphuma kwamandla, ngamamodeli amakhulu akwazi ukunika amandla amadivayisi amaningi ngesikhathi esisodwa. Ezinye iziteshi zamandla eziphathwayo nazo zinezici ezengeziwe, njengezimbobo ze-USB zamadivayisi wokushaja, noma izibani ze-LED ezakhelwe ngaphakathi zokukhanyisa.
