Ukuminyana kwamandla ebhethri ye-Lithium-ion kuphezulu, ngenxa yezizathu zokuphepha umthamo ojwayelekile ngeke uklanywe ukuthi ube mkhulu kakhulu, kepha amaseli amaningi e-lithium iron phosphate ngokusebenzisa izixhumi ze-conductive ochungechungeni futhi ahambisane nogesi, akha imojula yebhethri ye-lithium yelanga. Nokho, lokhu kudinga ukubhekana nenkinga yokungaguquguquki.
Ukungahambisani kweibhethri ye-solar lithiumamapharamitha ngokuvamile ahlanganisa umthamo, ukumelana kwangaphakathi, ukungahambisani kwe-voltage evulekile-circuit, ukungqubuzana kokusebenza kweseli yebhethri, okwakhiwa enqubweni yokukhiqiza, kuzothuthukiswa nakakhulu ngesikhathi sokusebenzisa, iphakethe lebhethri elifanayo ngaphakathi kweseli, elibuthakathaka njalo iba buthakathaka futhi isheshisa ukuze ibe buthakathaka kanye nezinga lokuhlakazwa kwemingcele phakathi kweseli le-monomer, ngokujula kwezinga lokuguga futhi libe likhudlwana.
Ukufundwa okuhlobene: What ls Solar Lithium Battery Consistency?
Lesi sihloko sizokwethula amaseli angahambisani lapho esetshenziswa ochungechungeni futhi ndawonye, imuphi umonakalo ozolethwa kubhethri ye-lithium-ion PACK nokuthi kufanele sibhekane kanjani nenkinga yamabhethri e-lithium elanga angahambisani.
Yiziphi Izingozi Zokungahambisani Nebhethri Le-Solar Lithium?
Ukulahlekelwa umthamo wokugcina we-solar lithium battery pack
Ekuklanyweni kwephakethe lebhethri ye-lithium yelanga, umthamo wonke uhambisana "nesimiso somgqomo", umthamo weseli ye-lithium yensimbi ye-phosphate embi kakhulu inquma umthamo webhethri yonke ye-solar lithium. Ukuze uvimbele ukushajwa ngokweqile kanye nokuchithwa ngokweqile, isistimu yokuphatha ibhethri izosebenzisa ukucabanga okulandelayo:
Lapho ishajwa: lapho i-voltage yeseli eyodwa ephansi kakhulu ifinyelela ku-voltage enqanyuliwe yokukhipha, lonke iphakethe lebhethri liyayeka ukushajwa;
Ngesikhathi sokushaja: lapho i-voltage ephakeme kakhulu yomuntu ngamunye ithinta i-voltage esike ukushaja, ukushaja kuyamiswa.
Ukwengeza, lapho iseli lebhethri elinamandla amancane lisetshenziswa ochungechungeni neseli yebhethri elinamandla amakhulu, iseli lebhethri elinamandla amancane liyohlala likhishwa ngokuphelele, kuyilapho iseli yebhethri elinamandla amakhulu lizohlala lisebenzisa ingxenye yomthamo walo, okuholela kumthamo webhethri. lonke iphakethe lebhethri lihlala linengxenye yomthamo walo esimweni sokungenzi lutho.
Ukuphila okuncishisiwe kwesitoreji samaphakethe ebhethri e-lithium elanga
Ngokufanayo, isikhathi sokuphila se-aibhethri ye-lithium yelangakuncike kuseli ye-lithium iron phosphate enesikhathi esifushane sokuphila. Kungenzeka ukuthi ingqamuzana elinesikhathi esifushane sokuphila yiseli ye-lithium iron phosphate enamandla aphansi. Iseli ye-LiFePO4 enomthamo ophansi kungenzeka kube ngeyokuqala ukufika ekupheleni kwempilo yayo ngoba ishajwa ngokugcwele futhi iyakhishwa njalo. Lapho ishiselwe njengeqembu lamaseli e-lithium iron phosphate ekupheleni kokuphila, lonke iphakethe lebhethri le-lithium lelanga nalo lizolandela ukuphela kokuphila.
Ukwenyuka ukumelana kwangaphakathi kwamaphakethe ebhethri elanga
Lapho okwamanje okufanayo kugeleza kumaseli anokumelana okuhlukile kwangaphakathi, iseli ye-LiFePO4 enokumelana okuphezulu kwangaphakathi ikhiqiza ukushisa okwengeziwe. Lokhu kuholela ekushiseni okuphezulu kwamaseli elanga, okusheshisa izinga lokuwohloka futhi kukhulise ukumelana kwangaphakathi. Ipheya lempendulo engalungile yakheka phakathi kokumelana kwangaphakathi nokukhuphuka kwezinga lokushisa, okusheshisa ukuwohloka kwamaseli anokumelana okuphezulu kwangaphakathi.
Amapharamitha amathathu angenhla awazimele ngokuphelele, futhi amaseli amadala ajulile anokumelana okuphezulu kwangaphakathi kanye nokuwohloka komthamo okwengeziwe. Nakuba lezi zinhlaka zithintana, kodwa zichaza ngokwehlukana isiqondiso sazo sethonya, zisiza ukuqonda kangcono ukulimala kokungahambisani kwebhethri ye-lithium yelanga.
Ungabhekana Kanjani Nokungahambisani Kwebhethri Le-Lithium Solar?
Ukuphatha Okushisayo
Ukuphendula inkinga yokuthi amaseli e-lithium iron phosphate anokumelana kwangaphakathi okungahambisani akhiqiza amanani ahlukene okushisa, isistimu yokuphatha okushisayo ingafakwa ukuze kulawuleke umehluko wezinga lokushisa kulo lonke iphakethe lebhethri ukuze umehluko wezinga lokushisa ugcinwe ngaphakathi kwebanga elincane. Ngale ndlela, ngisho noma ingqamuzana elikhiqiza ukushisa okwengeziwe lisenokushisa okuphezulu, ngeke lisuke kwamanye amaseli, futhi izinga lokuwohloka ngeke lihluke kakhulu. Amasistimu okuphatha okushisayo ajwayelekile ahlanganisa amasistimu okupholisa umoya kanye nawokupholisa uketshezi.
Iyahlunga
Inhloso yokuhlunga ukuhlukanisa imingcele ehlukene namaqoqo amaseli ebhethri ye-lithium iron phosphate ngokukhetha, noma ngabe i-batch efanayo yamaseli ebhethri ye-lithium iron phosphate, kodwa futhi kudingeka ihlolwe, imingcele yokuhlushwa okuhlobene kwebhethri ye-lithium iron phosphate amaseli ebhethri pack, ibhethri Pack. Izindlela zokuhlunga zihlanganisa ukuhlunga okumile kanye nokuhlunga okuguquguqukayo.
Ukulinganisa
Ngenxa yokungaguquguquki kwamaseli e-lithium iron phosphate, i-terminal voltage yamanye amaseli izoba ngaphambi kwamanye amaseli futhi ifinyelele embundwini wokulawula kuqala, okuholela ekutheni amandla alo lonke uhlelo abe mancane. Umsebenzi wokulinganisa wesistimu yokuphatha ibhethri ye-BMS ingaxazulula le nkinga kahle kakhulu.
Lapho iseli yebhethri ye-lithium iron phosphate ingeyokuqala ukufika ku-voltage esike ukushaja, kuyilapho yonke i-lithium iron phosphate cell voltage cell isala ngemuva, i-BMS izoqala umsebenzi wokulinganisa ukushaja, noma ukufinyelela ku-resistor, ukuze ikhiphe. ingxenye yamandla ebhethri yeseli ye-lithium iron phosphate ye-high-voltage, noma udlulise amandla kuseli yebhethri ye-lithium iron phosphate enevoltage ephansi. Ngale ndlela, isimo sokuvala ukushaja siyaphakanyiswa, inqubo yokushaja iqala futhi, futhi iphakethe lebhethri lingashajwa ngamandla engeziwe.
